General information on control

The term "control" is used in this manual rather for designation of a complex of procedures, than one separate procedure.

If from the moment of purchase of the car the schedule of routine maintenance is strictly observed, frequent inspections of level of liquids and a state subject to the increased wear of components will be carried out as it is offered in this manual, the engine will long remain in a good working condition, and need for carrying out any additional work will be minimized.

Is more often, however, happens so that the engine works inefficiently owing to neglect with regular service. Even more often it happens upon purchase of the second-hand car which owners did not trouble themselves frequent and regular checks and service. In this case, besides performance of usual procedures for routine maintenance, it will be necessary to make setup of the engine.

The first step in any procedure of control or diagnostics for the purpose of improvement of operation of the engine is check of extent of compression in cylinders. Check of a compression (address to the Section Check of a Compression) will help to define a condition of internal components of the engine and has to serve as the index when carrying out control and repair. If, for example, check of extent of compression indicates serious internal wear of the engine, usual control will not help to improve its work and will be waste of time and money. As procedure of check of extent of compression is the extremely important, the expert owning the equipment which is specially intended for this purpose has to see off it.

Reduction of the engine in a good working condition most often requires performance of the following procedures.
