Check of depression of the engine


  1. Razryazheniye of the engine, being created in a soaking-up branch pipe, is a good indicator of a condition of the engine. There is the following procedure of check of a razryazheniye:
  2. Warm up the engine to normal working temperature.

After a warming up of the engine put the gear shifting lever on "Neutral" (for And/t models put the gear shifting lever on a range of "R"), both establish the parking brake and block driving wheels.

  1. At the disconnected engine disconnect a vacuum hose of a regulator of pressure of fuel from an inlet collector and connect a tee, hoses and the special tool (компрессиметр and the hinge) between an inlet collector and the disconnected vacuum hose.

  1. Start the engine the every speed of idling, and consider indicators компрессиметра. Razryazheniye should be within the following technical characteristics. Technical characteristics of a razryazheniye (at a sea level): 52.6-72.3 kPa (40-55 cm рт. St, 15.7 – 21.6 inch hg) on the specified speed of idling.
  2. After check attach a vacuum hose to an inlet collector.
