6.4. The block of adjustment of temperature of air arriving in the engine

GENERAL INFORMATION

The block of adjustment of temperature of air arriving in the engine

1–folding shutter;

2–draft

The block of adjustment of temperature поступа yushchy air in the engine supports optimum air temperature for fuel combustion with the minimum quantity of emissions of harmful substances.

The optimum temperature of air submitted to the engine is reached by mixing of the fresh cold air arriving from a zabornik of air on the forward party of the car with air, a warmed-up final collector. The proportion of warmed-up and cold air is regulated by the provision of a folding shutter in the block in front of the air filter. The block of adjustment copes either a vacuum diaphragm or a wax capsule. The vacuum diaphragm copes the sensor of temperature located in the case of the air filter (see drawing).

PERFORMANCE ORDER
1. Check of the block of adjustment температу ры air arriving in the engine start to make on the cold engine. First of all check the provision of a folding shutter for what on a vacuum regulator uncover the air filter and be convinced that the folding shutter is completely open. At completely open folding shutter in the engine cold air arrives. Start the engine and check that the folding shutter moved, passing in the engine the air which has been warmed up by a final collector. If in the block of adjustment the wax capsule is established, the folding shutter on the cold engine should be in the provision of a transmission in the engine of the air which has been warmed up by a final collector.
2. Temporarily establish a cover on a vacuum regulator.
3. Start the engine and warm up it to working temperature.
4. Uncover a vacuum regulator and check that a folding shutter установ Lena in the provision of a transmission in the engine of only cold air. At low temperatures of external air the shutter should be established in the provision of mixing of cold and warmed-up air. On models with a wax capsule, using a mirror, check the provision of a folding shutter which should be same, as well as at a vacuum regulator.
5. If the folding shutter does not work as it is required, replace the case of the air filter.
