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 gaps of valves (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.

Petrol engine


1. Connect a tachometer and a measuring instrument WITH to the engine. Mechanics use special WITH - a 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 the catalytic converter on an exhaust pipe it is impossible to receive the correct indications of the contents WITH.
2. To adjust manually turns of idling it is impossible, as the stabilizing valve of idling is put in action by the electronic control unit. If at normal working temperature of the engine turns of idling do not correspond to the values specified in Specifications, check system of a fence of air on existence of leaks, and also operation of the valve of idling.
3. Verify measuring instrument indications WITH with the values given in Specifications. If adjustment is required, take a cap from a measuring instrument of an air stream and turn the adjusting screw before obtaining demanded value (on some models the six-sided key can be demanded). In summary establish a new protective cap.

Diesel engine

The most complex problem at adjustment of idling is represented by tachometer accession as available and tachometers are intended to sale for connection to the coil of ignition of the petrol engine. To reach necessary adjustment of idling it is possible under condition of the 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 everything electric consumers. If automatic transmission is established, switch a transmission in neutral situation.
2. Start the engine and check number of its turnovers of a tachometer or estimate it aurally. Non-uniform operation 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 evenly at single turns. For increase of number of turns the screw is rolled. The control lever gas thus moves outside.
4. Holding the adjusting screw a screw-driver, tighten a lock-nut.
