Scooter engines: review of Chinese models 139QMB and 157QMJ and D1E41QMB

The 157QMJ 150cc engine is a fairly common type of engine, which is now installed on Chinese scooters and is a copy of the Japanese Honda GY6 engine. The characteristics and service life of this 4t engine allow it to be subjected to tuning.

In this article, we present to your attention the tuning of the GY6 engine using the example of the YIBEN YB150T-15 scooter, namely an increase in piston volume from 150 cc to 170 cc. It is worth noting that the modernization of the scooter was carried out in Australia, which introduces adjustments to the prices of spare parts for tuning. The so-called collective farm is minimized here, tuning can be called bourgeois and scooterists who want to save money will not be suitable.

The marketing name of the prototype scooter in Australia is Ozooma 150 Maxx, released in 2007, however, this is not important, since these engines are installed on many models of Chinese cubic scooters, for example Viper Storm 150. The moped owner does not need to upgrade to a more powerful scooter model with 250cc engine. The purpose of upgrading the motor from 150cc to 170cc is to add a little top speed to the scooter, up to about 100 km/h without spinning. An untuned Yiben 150 scooter can travel approximately 80 km/h over a long distance without the risk of causing damage to the power unit. Another goal was to complete this entire upgrade without removing the engine from the scooter.

This engine can be considered Japanese. In the late 1990s, Honda Motor launched a new line of GY6 scooter engines, which replaced the units of the earlier Tact and Dio models. The new engine became a 4-stroke with a cylinder tilted forward (versus 2-stroke with an almost vertical, even slightly tilted cast-iron cylinder back). The number of valves is two, forced air cooling. Initially, two similar designs were developed: for 50 cm3 and 125 or 150 cm3. GY6 was installed on scooters of the (CH125/CH150) Elite and Spacey families.

Now this family of engines is installed on all scooters made in China, because this engine has proven itself to be the best: high performance, low consumption, easy to repair, all spare parts are available in our store and in any city of the Republic of Kazakhstan, low cost of the engine and spare parts, achieved through mass production around the world, ease of repair, reliability of design and components, high power output.

What kind of oil to pour into an ATV engine

ATV engine oil must first match the type of engine. The vast majority of existing models are equipped with one- or two-cylinder water-cooled gasoline engines, that is, they require API S oils. A small number of ATVs produced in the simplest configuration continue to use 2T engines - they are simpler, cheaper and lighter. In this case, only special two-stroke oils of API TC quality class can be used.

Heavy utilitarian ATVs, including those of the Side-by-side class, are also equipped with diesel engines. For them, it is worth choosing a specialized oil for diesel engines (API class group C), but it is also possible to fill with universal motor oils, since their characteristics are suitable for diesel engines used on utilitarian ATVs.

The frequency of oil changes is determined by the manufacturer and is given in the service book. It is recommended to change the oil at the beginning of the season if the ATV is not used in winter, even if it has only had low mileage in the previous year.

Local Ukrainian paragliders have approached me more than once. The reason is that I am engaged in high-quality Taiwanese tuning of scooter engines, which many are trying to adapt to their needs. Maybe there are experienced users on this forum who can correctly formulate the problem. which the engine must solve. I already understand that light weight is needed, but what else? In addition to tuning for Chinese, Taiwanese, Japanese engines with a volume of 50 to 250 cc, there is also a little more tuning for “Europeans”. Moreover, I cooperate with some engine manufacturers in Taiwan - I can find a 2T or 4T engine assembly. Puzzle - maybe I can help you. I have been helping scooter riders since 2010 and quite successfully. We respect the rules of the forum - we do not turn the forum into a “garbage dump” or a commercial platform.

p.s. Maybe in the end nothing will work out, scooters and paragliders are not the same thing. But it's worth a try

For starters: Here is a kit made from 125 cm3 - 233 cm3 Tuning kit GY6, 152QMI, 157QMJ

GY6 233cc

Based on the Chinese and Taiwanese engines, which are clones of the Honda GY6 of different quality, I can say that there are two options:

1. Engine crankcase of most models with dimensions between the engine studs of 54 mm: CPG 63 mm (180 cm3) + long-stroke crankshaft fits into such a crankcase

almost up to 200 cm3 + head with large or super-large intake/exhaust and corresponding “wide” camshaft or 4-valve with large intake/exhaust and corresponding “wide” camshaft

2. Engine crankcase with a distance between studs of 57 mm: CPG fits up to 67 mm + long-stroke crankshaft

up to 233 cm3 + head with large or super-large intake/exhaust and corresponding “wide” camshaft or 4-valve with large intake/exhaust and corresponding “wide” camshaft

According to two-stroke variants from the common ones: Engine from BVS 100 + piston 135 cm + crankshaft

There is no need to confuse real Taiwanese CPG with a fake. Unfortunately, such “good” is enough to sell the Chinamotoprom CPG as a Taiwanese one - this has become a favorite “business”

Many Taiwanese tuning manufacturers have only begun to promote their brands in the last couple of years, and previously worked as OEM/ODM partners of many European and American tuning brands. Modern European scooters often contain a majority of Taiwanese parts, including engines. In Taiwan there are 5 manufacturers of motorcycle equipment and they do everything well and with high quality, unlike China where there are hundreds of “manufacturers” and only a few do it well, and then under European or Japanese supervision. I was in Taiwan personally at the factories, I know what I’m talking about.

Sorry, yes *** let's say you need a Taiwanese tuning piston for which you need to remake half of the engine so that those 125 or more cubes do not bend the rest into the unit, if the scooter from its native Japanese produces 10 hp?

Here's a different approach. A green teapot comes to the store, for example, for a new CPG and the seller tells him that for his scooter there are 3 types of spare parts manufacturers, analogue (Japan, Italy, etc.), Taiwan and China! The pricing policy, I think, is clear to everyone. And here the buyer thinks that China is f***, the original is too expensive, and in the end the average is Taiwan. That’s the whole market. From here it emerges that the stingy pays twice, and the stupid pays three times.

And why fuss and throw away your hands if you can buy a budget version of the same Rocket or Archimedych for a PM installation?

I apologize again - this is my personal opinion and attitude towards second-rate products.

You probably started talking about 2T engines? If yes, sorry, I didn’t understand right away.

Small-scale equipment fell out of interest back in 2009 in Ukraine and almost completely stopped being imported to us, so we never even bothered with tuning for “fifty dollars” and 90 cc 2T Japanese-made ones. The only thing supplied for the 2T was a 135 cc CPG with a crankshaft for the Yamaha BVS.

Despite all the variety and variety of Chinese scooters on Russian roads, their engines belong to only two categories. This is a two-stroke scooter engine and a four-stroke one.

These categories differ greatly in the number of models produced, so let's start with the largest category - the 139QMB four-stroke scooter engine. Its history began at the end of the last century, when in the 90s the Honda branch developed the first such scooter engine model, and today it is called KYMKO. Ten years later, China adopted this development and, together with Honda, began mass production. How good the final version turned out can be judged by the fact that scooter engines labeled 139QMB are regularly purchased from Japan and sold there under the Honda brand.

The 139QMB scooter engine has already become a legend in the motorcycle world, and Hongling Corporation, which officially produces it, installs this engine not only on motorcycles of its own brand, but also successfully sells them for assembly at prices of other motorcycle brands. The recognition of this scooter engine is simply colossal: the marking is located on the left side of the crankcase. The serial number begins with 139QMB, followed by the product number in the production batch.

The 139QMB scooter engine is practically flawless, it can be treated with some degree of carelessness or negligence (but, of course, in moderation). The warranty usually covers the first 5 thousand kilometers. This distance is necessary for the scooter engine to allow grinding in of all its units and components. Once the initial parameters are passed, the lifespan of which the 139QMB scooter engine is capable is about another 20 thousand kilometers. And this is at an average speed of 90 km/h. The engine power is more than enough for a full-size 2-seater scooter.

Some Chinese corporations decided not to look for easy ways and created their own unit. This scooter engine is marked 1P39QMB, and in terms of its external characteristics it is an exact copy of 139QMB. But if you look in more detail, the differences are clearly striking. The 1P39QMB scooter engine is assembled without adjusting the clearances in all valves. The same negligence can be seen in the carburetor, which requires mandatory adjustment and cleaning before starting. In the hands of an experienced scooter rider, the engine will, of course, work, but its main purpose is to make the scooter even less expensive. All budget options that are good for several trips are equipped with just such engines.

The engine of the scooter model 1P39QMB will not have proper dynamics if it has not been run in before use. Only after 2 thousand kilometers does it enter the optimal phase of operation, but after 10 thousand kilometers its performance drops sharply.

The 157QMJ scooter engine models can be produced in two volumes - 150 and 125 cc. see. They are installed on more expensive scooters “BM”, “Honling”, “Forsazh” and others. In terms of reliability and functionality, the 157QMJ scooter engine is an absolute copy of the 139QMB. Also, many design details in it are reminiscent of mass-produced Japanese analogues.

The service life of such engines is already an order of magnitude higher and amounts to 25 thousand kilometers. It has powerful acceleration coupled with very high speed. Their main drawback (if this can be considered a drawback) is their higher cost compared to the previous model. But having bought a 157QMJ scooter engine once, this purchase will serve faithfully for many years, without requiring major intervention in its operation.

There is only one two-stroke scooter engine made in China. Its model is D1E41QMB. It has a chain reverse gear, which fundamentally distinguishes it from all other representatives of this class of units. Reliable operation of such a scooter engine is achieved by adding oil to gasoline (proportion 40 to 1). The engine's lifespan is short - about 10 thousand kilometers, and subsequent repairs are required. It is necessary to replace the rings, which in terms of monetary investment will not be an expensive process. This scooter engine cannot handle speeds that exceed 50 km per hour.

Photo report: Repair of engine 157 QMJ of Atlant scooter (150 CC)

This article will show only the main stages of assembly and repair of the 157QMJ engine, which is very popular in Russia. If you describe the entire assembly process from start to finish, the article simply will not load in your browser. Therefore, for your convenience, at the end of the article and more, there are links that will lead you to where any stage of assembly and disassembly of a mechanism or assembly is of interest to you will be described in more detail.

It is worth noting that the 157QMJ engine is very simple in design, so to repair it there is no need to install additional pullers or devices. The engine that we will be assembling today was very worn out, so much so that there is nothing to talk about here. Whether you like it or not, you will have to change almost all the parts, from oil seals to the crankshaft. More details about disassembling this engine are written in the article: Disassembling the engine 157 QMJ of the Atlant scooter (150 SS)

So, first we clean off the remnants of old gaskets and sealant from the planes of the crankcase halves; if necessary, we “drive” the threads under the mounting bolts; by the way, we also do not forget to “drive” the threads on the bolts.

We blow through the oil channels with a compressor, thoroughly clean all parts from dirt and wash them.

Let's start assembling the engine as usual by installing new seals. Before installing the seals, it is advisable to heat the crankcase halves with a hair dryer and then press them into place using a mandrel. After pressing the oil seals, their edges must be lubricated with some kind of grease or engine oil. We will install a new crankshaft, since the old one “decided to live a long time.”

Take the crankshaft and insert it into the right half of the crankcase.

We turn the engine around, take the key of the overrunning clutch and insert it into the groove on the axle.

Lightly tap it with a hammer, making sure that it sits evenly in the groove without distortion.

We insert the oil pump drive axis into place.

We take the oil pump drive chain (in our case the chain is new), put it on the oil pump sprocket, then put it on the middle sprocket of the crankshaft, then put the pump sprocket on the drive axis.

Please note: the oil pump drive chain must be placed on the middle sprocket of the crankshaft.

We insert sprockets, a tin rod or a stick under the tooth and tighten the nut on the oil pump axis.

Screw the oil pump drive housing into place.

We take the overrunning clutch body, put it on the axle, turn the body so that the key on the axle fits into its groove on the body, then push the clutch all the way.

Insert the starter idler gear shaft

We put the starter intermediate gear on the axle

We put the overrunning clutch gear separator in its place.

We put the overrunning clutch gear on the axle

We put on the washer, thoroughly clean the threads of the trunnion and the nut, then degrease it, apply a “blue” locking agent to the threads (preferably) and using an old unnecessary screwdriver and hammer, tighten the nut (left-hand thread).

We take the second half of the crankcase, place some kind of block under it and insert the timing chain into it (the timing chain is also new).

We degrease the crankcase connector planes, insert the guide bushings (marked with arrows), and install a new gasket. For greater reliability, we apply sealant to the surface.

Lubricate the left crankshaft bearing with engine oil; it is best to apply oil to the bearing with a medical syringe. After everything has been done, carefully connect the crankcase mats.

Immediately tighten the bolts (marked with arrows).

In the same way, degrease the surfaces, insert the guide bushings (marked with arrows), install a new gasket and put on the cover.

We take the mounting bolts and insert them into place.

The bolts should be tightened crosswise, first tighten them lightly, then tighten them again but with greater force, and so gradually increasing the tightening force over several “circles”, tighten the bolts completely. Immediately after assembly (otherwise you will forget), pump engine oil into the bearing of the lower connecting rod head with a syringe. Just in case, apply sealant to the starter O-ring.

We install the starter in its place and tighten the bolts.

Engine device

Beginning scooter riders, if they need to repair the motor, try to understand its design. Diagram 157QMJ will help you obtain information about the structure of the power unit and its components. Having dealt with it, you can not only purchase the necessary spare parts for the 157 QMJ engine, but also correctly perform the work of assembling and disassembling the engine. Structurally, the motor is practically no different from its GY6 counterpart. The 157 QMJ has the same cylinder-piston group, clutch, crankcase, camshaft and muffler.

Technical characteristics and design of ZIL 157

Serial production of this car began in the late 40s of the last century. The technical characteristics of the ZIL-157 allowed this technology to be in demand for half a century. The cars were discontinued only in 1994.

Application of the ZIL-157 car

The initial purpose of the ZIL-157 is to meet the needs of the defense industry. The vehicle carried ammunition, various cargo and soldiers. Additional equipment with a winch made this type of transport convenient for evacuation of tracked and wheeled vehicles.

Over time, modifying the truck, the designers adapted it into the national economy:

• in construction;
• in various industries;
• in agriculture;
• in logging;
• on fish farms;
• in hunting grounds.

The ZIL-157 truck was actively in demand abroad. In Finland, this technique is still used in logging.

Thanks to its successful design, the car was successfully operated in all weather conditions. Adjusting the tire pressure made it possible to move at optimal speed on any soil - on arable land and off-road, in swampy areas and on sand dunes, as well as snow drifts.

Specifications

ZIL-157 has been popular for so long due to its technical parameters, the main ones of which are shown in the table.

Technical characteristics of the first models

In the first models, a worm steering mechanism with a 5-speed gearbox was used for control. In more modern cars, the steering wheel is equipped with a hydraulic booster. The transfer case is 2-speed and has a front axle clutch. The rear axles are parallel-separate.

In improved models, each bridge was supplemented with a reinforced casing. The front suspension is a set of polyelliptic springs with hydrotelescoping shock absorbers, the rear suspension is a balancing type of springs.

The main braking system is a drum-type, pneumatic-driven type on all wheels. The parking brake is also a drum type, but has a mechanical drive to the transmission.

Description of the car engine

The first engines for the ZIL-157 were created taking into account the elimination of the shortcomings of the engines installed on the predecessor (ZIS-151). The improvements included such parameters as engine power, degree of overheating, trouble-free operation, gasoline consumption, etc. The modernization of the engine lasted until 1978.

The main type of engine of this car is carburetor, running on gasoline. But several models were released with a diesel engine, and it did not live up to expectations. The main disadvantage is the high level of vibration and shaking, leading to discomfort for the driver and passengers.

Engine Specifications

Type of gasoline engine – 4-stroke. The block consists of 6 cylinders arranged in a row. Made of cast iron, and the cylinder head is made of aluminum. The block has a closed “jacket”. The coolant circulates through the block circuit.

Engine characteristics:

The table shows the parameters of the base car.
Thanks to improvements in subsequent models of the crankshaft, oil pump, pump seals, and the introduction of closed crankcase ventilation, many characteristics of the ZIL-157 engine were improved. In the latest models, it has become possible to install an additional tank with a capacity of 65 liters. This makes it possible to cover a distance of more than 500 km on one gas station.

Despite the simplicity of the design and unpretentiousness, the engine is trouble-free and reliable in operation. Even after inactivity, it starts quickly, but is sensitive to low temperatures, so in winter it requires special care.

Over time, the thermostat on the engine was modified, but the cars continued to be equipped with insulating covers until the last moment. The modifications also eliminated problems with motor overheating.

Cabin structure

The original cabin of the ZIL-157 was uncomfortable for both the 2 passengers and the driver. Over time, thanks to telescopic shock absorbers, the designers made the steering easier, and the driver began to exert less physical effort when driving. By introducing an additional radiator with a fan-impeller, it became possible to heat the cabin and the front window.

Equipping the interior with a dashboard made it possible to control the car’s systems: axle gears, turning off headlights, lubrication and brake pneumatic pressure gauges, foot start, winch levers, etc.

Modifications of the ZIL-157 truck

During the entire time that ZIL-157 rolled out of the container at the Likhachev plant, the cars were constantly modernized. Basic models are characterized by the presence of a tire pressure system, single-pitch tires, split wheels, foot-operated starter, and a winch mounted on extended brackets.

The main stages of truck modernization are shown in the table.

Modifications of ZIL-157:

In addition to the basic models, other options were used: special vehicles for the army, workshops on wheels, vehicles for electrical supply, fire trucks.
