Check and adjustment of turns of idling of the engine and level WITH


The engine should be heated-up to normal working temperature, with correctly established corner of an advancing of ignition and the adjusted backlashes of valves (there where they are regulated). The air filter should be in a good condition, and all electric components (including air central air where it is available) should be switched off.

The petrol engine


1. Connect a tachometre and a measuring instrument WITH to the engine. Mechanics use a special With-tester, which probe is established in the pipeline of system of release, but it is possible to use a usual tester which is inserted into an exhaust pipe. However pay attention that on models with каталитическим the converter on an exhaust pipe it is impossible to receive correct indications of the maintenance WITH.
2. To adjust manually idling turns it is impossible, as the stabilising valve of idling is put in action by the electronic block of management. If at normal working temperature of the engine idling turns do not correspond to the values specified in Specifications, check up system of a fence of air on presence of leaks, and also work of the valve of idling.
3. Verify indications of a measuring instrument WITH with the values resulted in Specifications. If adjustment is required, take заглушку from a measuring instrument of an air stream and turn the adjusting screw before reception of demanded value (on some models it can be demanded шестигранный a key). In summary establish new protective заглушку.

The diesel engine

Most the challenge at idling adjustment is represented by tachometre joining as available and tachometres are intended sale for connection to the coil of ignition of the petrol engine. To reach necessary adjustment of idling it is possible under condition of correct adjustment of valves and the moment of injection of fuel.

Check of idling of the Diesel engine is made as follows:


1. Start and warm up the engine to working temperature. Disconnect from the engine all electric consumers. If automatic transmission is established, switch a transmission in neutral position.
2. Start the engine and check up number of its turns on a tachometre or estimate it on hearing. Non-uniform work of the engine is felt at once.
3. If the number of turns of the engine falls outside the limits Specifications, a screw-driver turn the adjusting screw so that the engine worked in regular intervals on single turns. For increase of number of turns the screw is rolled. The control lever gas thus moves outside.
4. Keeping the adjusting screw a screw-driver, tighten a counternut.
