General information about settings and adjustments

The name "control" in the real Management is meant as not separately taken procedure of adjustment any of parameters of systems of the car, and the whole complex of the adjustments, allowing to achieve maximum efficiency of return of the engine.

If the owner of the new car from the date of its acquisition strictly adhered to the schedule of procedures of routine maintenance (see. Undressed the Schedule of routine maintenance), rather often carried out checks of critical parameters, supported demanded level of lubricant liquids, the engine will need extremely seldom performance of additional service and regenerative repair (over replacement of components subject to raised wear and expendables).

On the other hand, in case of the negligent relation to performance of procedures of regular maintenance and frequent violation of established periods of carrying out checks, efficiency of return of the engine will surely decrease sooner or later. The probability of emergence of such situation in case of acquisition of the car which was in the use is especially high. In such cases there is a need for performance of a complex of settings of the power unit over amount of works on routine maintenance of the car.

The first step at control or diagnostics of malfunctions of the engine working with lowered return always is check of kompressionny pressure in cylinders (see. Head the Engine) which analysis of results allows to estimate the general condition of internal components of the engine and to draw up the plan of the forthcoming adjusting and/or recovery operations. For example, if check of kompressionny pressure revealed signs of serious internal wear of the engine, a usual complex of settings will be insufficiently to correct a situation, and its carrying out is waste of time and means. In view of value of information received as a result of check of kompressionny pressure, it is necessary to charge its performance to rather skilled and qualified mechanic having necessary diagnostic devices.

Below lists of the main adjusting procedures, allowing to achieve maximum efficiency of return from the engine which was in a working mechanical order are provided.

List of the minimum complex of checks and adjustments

• Check levels of all concerning operation of the engine of liquids (see. Section Check of levels of liquids).
• Make cleaning and check of a condition of the storage battery (see. Section Check, service and battery room charging).
• Make check of a condition and service of components of system of cooling (see. Section Check of a condition of components of system of cooling).
• Check a condition of all hoses located in an impellent compartment (see. The section Check of a condition and replacement of the hoses located in an impellent compartment).
• Check a condition and serviceability of functioning of the PCV valve (see. The section Check and replacement of the valve of system of operated ventilation of a case (PCV)).
• Check a condition of a filtering element of an air purifier (see. The section Replacement of a filtering element of an air purifier).
• Check a condition of spark plugs (the petrol engine) (see. Section Check of a condition and replacement of spark plugs (petrol engines)).
• Check installation of klapanny gaps, in case of need make the corresponding adjustment (see. Section Check and adjustment of gaps of valves.
• Check installation of turns of idling (see. Section Check and adjustment of turns of idling).
• Check installation of a corner of an advancing of ignition, in case of need make the corresponding adjustment (see. Head engine Electric equipment).
• Check a condition and effort of a tension of driving belts, in case of need make necessary adjustment (see. Section condition Check, adjustment of effort of a tension and replacement of driving belts).
• (see. Section Check of a condition of components of a suspension bracket and steering drive).

List of a full complex of checks and adjustments

In addition to the checks listed above:

• Check a condition and serviceability of functioning of EGR system (see. The section Check of serviceability of a condition of components of system of a retsirkulyatsiya of the fulfilled gases (EGR)).
• Replace the PCV valve (see. The section Check and replacement of the valve of system of operated ventilation of a case (PCV)).
• Replace filtering element of an air purifier (see. The section Replacement of a filtering element of an air purifier).
• Check serviceability of functioning of a power supply system and a condition of its components (see. Section Check of a condition of components of a power supply system).
• Replace the fuel filter (see. Section Replacement of the fuel filter).
• Check serviceability of functioning of system of ignition and a condition of its components (see. Head engine Electric equipment).
• Check serviceability of functioning of system of a charge and a condition of its components (see. Head engine Electric equipment).
