Kit engine temperature sensor for snowmobile

Additional equipment for a snowmobile

Controlling engine temperature is extremely important for air-cooled engines.

Especially for two-stroke engines, piston cooling is significantly worse compared to four-stroke engines.

Which, if overheated from a lean mixture, can lead to burnout of the bottom of the piston.

And if a two-cylinder snowmobile is still able to continue moving for some time after this, then a single-cylinder one will have to be towed or abandoned while going for help.

To detect signs of overheating in time, engine temperature indicators are used. Most of them provide not only a bright digital temperature display, but also indicate overheating both visually and audibly.

The temperature can be taken from either one or two cylinders.

Additional options may include an indication of engine speed and ambient temperature.

Even the latest turbocharged sleds have tuning solutions like the KOSO X-2 Boost Gauge, which shows boost pressure, mixture ratio, and more.

How it works

Back in the 80s, it was popular to install aircraft instruments obtained in various ways on Burans and Ikars.

They read the temperature through a ring with a built-in thermocouple installed under the spark plug.

Many modern temperature sensors offered for snowmobiles use the same principle.

On Lynxes, the cylinder head has an unoccupied threaded technological hole. Temperature sensors were produced for them that were wrapped in this hole, but due to the discontinuation of snowmobile production, they are quite difficult to find.

Other snowmobiles will require drilling of the cylinder head . For new equipment that is under warranty, this is not very acceptable.

For water-cooled snowmobiles that do not have a standard coolant temperature indicator, there is an offer from Koso and its Chinese clones.

This is a small metal pipe, in the middle of which there is a thread for the sensor, and is inserted into the cut hose of the cooling system.

As mentioned above, the main problem of two-stroke engines is piston burnout when the mixture is lean.

Exhaust gas temperature sensors allow you to track the composition of the mixture quite accurately.

Thus, such a device is not only standardly installed on the Rybinsk Taiga Varyag 550, but is also recommended for use on all Taiga snowmobiles.

A number of manufacturers of such devices are trying to expand their functionality by combining temperature indicators with a tachometer.

This practically does not complicate the installation of the device, since the speed sensor is just a few turns of wire that are wound around a high-voltage wire.

Installation examples

On the Varyag 500 snowmobile, unlike the 550 cc version, there is no standard temperature sensor.
You can install the KOSO RX2N+ RMZ used there in the same way - in this case, the device itself is installed in place of the standard speedometer and connected to the power supply.

And then a special clamp from the installation kit is put on one of the exhaust pipes as close to the engine as possible.

A threaded bushing welded to the clamp is used as a guide for drilling a hole in the pipe, and then the sensor is screwed into it. Installation in this case is simple, but the high price of the kit itself is off-putting.

You can also use kits with temperature sensors for spark plugs - both two-channel (with temperature control for each cylinder) and single-channel.

When installing a single-channel indicator on either this or any other snowmobile with two cylinders, it is advisable to install the sensor under the spark plug of the cylinder remote from the cooling impeller - it is blown with hotter air and will overheat first.

For Lynx snowmobiles, it is convenient to use the technological hole on the side of the cylinder head . When installing the sensors that come with the TSITD-4 device, it needs to be modified by deepening it with a drill by 6 millimeters.

The hole is filled with heat-conducting paste, and the sensor is wrapped there, and the indicator body is cut into the dashboard.

Typically, devices are produced round to simplify installation, since their installation requires only a crown and a screwdriver.

For a small-sized snowmobile like the Irbis Dingo 150, it is optimal to install a temperature sensor in the form of a ring under the spark plug - for example, complete with an affordable “MT-30 Motor Thermometer” device.

The open design of the snowmobile will make wiring much easier.

But there is a requirement for the design of the temperature indicator itself: there is nowhere to embed it, therefore, it must be designed for external installation or you will have to purchase a special mount (podium) for it.

For installation on an imported snowmobile, for example, a popular Yamaha company in Russia, it may be convenient to have different designs of sensors depending on the design of the snowmobile.

Thus, the free space on the Yamaha Viking VK 540 panel allows you to embed popular CITD devices there.

The design of a number of snowmobiles allows temperature sensors to be installed not under the spark plugs, but under the nuts securing the cylinder heads.

This method is more convenient, as it simplifies changing spark plugs and eliminates the possibility of damaging the sensor.

In this case, the sensors need to be placed closer to the center of the engine - in this case, the range of readings will be the smallest due to the different distance from the cooling fan.

What is the operating temperature of the Taiga 500 snowmobile engine: critical and peak overheating rates

Correct, stable operation of the engine depends on many factors, the most important of which is its temperature, this is especially important for two-stroke air-cooled engines - this fully applies to snowmobiles.

At high speeds, as well as under significant or even extreme loads, this parameter can rise to a critical level. Long-term operation in this mode leads to quite serious damage, which means expensive repairs.

Therefore, users need to know what the operating and critical temperature of the Taiga 500 snowmobile is.

How to Measure Snowmobile Engine Temperature

It is necessary to monitor the operation of the engine. Need to:

• Listen to the engine running.
• Monitor his temperature.

In order for the mode to be maintained at the desired level, all snowmobiles have a cooling system. It is better to control it using a special temperature sensor.

This is especially important to do on two-stroke engines.

Not all snowmobiles have sensors installed from the factory; therefore, on many it is highly recommended to install them yourself or in a workshop.

So, when a digital display is displayed on the dashboard, you can control the fairly accurate temperature of each cylinder.

The principle of operation of the sensor for measuring engine temperature on the Taiga 500 Snowmobile

The operating principle of most sensors is the same as on Soviet-made snowmobiles:

1. Under the glow plug there is a ring with a thermocouple inside.
2. The signal from this element comes to a device that controls the temperature.

On the Lynx snowmobile there is a threaded hole on the cylinder into which the indicator is screwed.

Other models of similar equipment do not have such holes - they need to be drilled in order to install the sensor. If the snowmobile is under warranty, then this solution is not the most successful - this could result in losing the warranty.

If the snowmobile is water-cooled, then it is possible to install a metal pipe with a thread, which is built into the cut hose of the cooling system.

On the Taiga 500 snowmobile, a temperature sensor (CITD-5 TPT-3-6U) is installed under the spark plug.

This solution is relevant for any motorcycle.

Using CITD 5, you can identify not only the engine temperature, but also other important indicators:

• Broken fan belt.
• Air inlet clogged with snow.
• Based on the temperature difference (between the cylinders), determine malfunctions in the fuel supply or spark formation, air leaks and engine overload.

High temperature is the cause of the above malfunctions, and the snowmobile owner should not only be alert to it, but also look for the reasons for its occurrence.

a brief description of

Brief characteristics of the device:

1. Range minus 50 – plus 250 °C.
2. Critical (at which a signal about engine overheating is given) - 195°C.
3. The error is 2 degrees, no more.
4. The device is intended for both snowmobiles with and without batteries (AC or DC). Voltage – 12V.
5. Ambient operating temperature – minus 50 – plus 50 °C.
6. The case is made in size 45×93 cm.
7. There are two LED indicators that display the temperature of each cylinder individually.
8. The device is controlled from a multifunction button.

When the temperature of one or both cylinders reaches 195°, the display displays the temperature up to the measurement limit (250°C) in pulsation mode.

This signal from the indicators indicates that the critical temperature is approaching.

How to install the device

In order to install the CITD 5 device, you need to embed it into the panel. The housing is protected from falling out of the cut-out window by means of L-shaped brackets secured with screws.

What is the operating temperature of the engine on the Taiga snowmobile?

As is already clear from the above, the operating temperature of the Taiga snowmobile engine should not exceed 190°C, and its increase serves as a signal to take measures to reduce it.

If this indicator continues to increase, then it is strongly recommended not to turn off the snowmobile engine. In this case, the gas is released and movement continues at medium speeds, or if this does not help, then you should stop and sharply release the high temperature.

The readings of the device must be constantly monitored, and the temperature difference between both cylinders must also be monitored - it should not exceed 15 ° C, although ideally differences are allowed no more than five degrees.

When the engine warms up, you need to start driving at 30-35°C.

What is the critical engine temperature of the Taiga snowmobile?

When the engine temperature exceeds 200 degrees, there is a high probability that the engine may undergo irreversible physical changes, which will result in expensive repairs. The critical engine temperature of the Taiga Varyag 550V snowmobile, as well as the 550 model, is no different.

However, the same 200 degrees are acceptable, but only for a short time.

The consumer should have an idea of ​​what operating temperature the engine should be on the Taiga snowmobile.

You should not skimp on high-quality oils - this will significantly extend the “life” of the engine.

Functionality check

You can check the functionality of the sensor after purchase even before installing it on the snowmobile. Subsequence:

• Connect the device to the battery.
• Heat the sensor in any way. For example, using a construction or even a regular hairdryer.

Of course, it would be more correct to subject the sensor to the maximum specified heating of 250 degrees in order to finally verify its serviceability.

Sensor cost

The cost of the CITD with sensors for snowmobile spark plugs is up to 7 thousand rubles. This is the factory price.

The length of the wire (including spark plug cables) is 2.4 meters, and if necessary, you can increase it yourself.

The device is supplied with everything necessary for installation.

The warranty is 12 months and the minimum service life is 5 years.

Technical characteristics of CITD 5

Choosing between two models

Quite often, consumers are faced with the question: is the Taiga Varyag 500 snowmobile or 550? Both models are very popular.

In order to answer this question correctly. The characteristics of both models should be studied.

Technical characteristics of "Taiga Varyag 500"

1. 2-cylinder engine with a volume of 503 cm3
2. Air cooling
3. Reliable and advanced carburetor “RMZ 500”
4. Fuel system - “MIKUNI” (Japan)
5. Electronic ignition from DUCATI (Italy)
6. Two seats - driver/passenger (the model was planned to be single-seat)
7. Chassis - shock absorbers. Stroke – 115 mm (previous – 150 mm)
8. Heated grips
9. Ergonomic tubular steering wheel from the Tiksi snowmobile

Not included in the standard configuration:

• Electric start
• Separate lubrication system

Technical characteristics of "Taiga Varyag 550"

"Taiga Varyag 550" is equipped with components suitable for the climate of Siberia, the Urals, and the Far North.

Technical characteristics of “Varyag Taiga 550V” (what has been added):

1. Telescopic suspension "Bars 850". Stroke – 277 mm.
2. The front suspension is equipped with a horizontally mounted shock absorber to facilitate movement on uneven roads. This added energy consumption.
3. The tracked ground hitch has been modernized. This improved cross-country ability, dynamics at high speed and when braking, as well as maneuverability.
4. The high handlebar improves both ergonomics and appearance.

Thus, this “Varyag” comes with improved equipment, but is not a source of competitive advantages.

Conclusion

It is advisable to purchase sensors from the manufacturer to avoid buying counterfeits. You can, of course, not buy or install anything, thus saving your own money, effort and time. But, as practice shows, such savings can very easily backfire on the owner of a snowmobile - engine repairs cost many times more.

What is the cost of the work?

The cost of installing additional devices on snowmobiles can vary significantly, even in the same city.

The most expensive installation of mortise indicators is made even more expensive by the need to drill holes for threaded temperature sensors.

Also, the order of numbers in price lists is inversely proportional to the level of competition.

On average, the work of installing a mortise indicator with sensors for spark plugs costs the client 200-2500 rubles; threaded sensors can add another thousand to the price.

If the indicator housing is attached to the dashboard with double-sided tape or through a bracket, installing such a kit is unlikely to cost more than one and a half thousand rubles.
