3.7. The car is badly dispersed
So the knots which malfunction influences dynamics of the car are located in подкапотном space.
It is a lot of reasons of deterioration of dynamics, the cores can be defined so.
1. Malfunction of the engine — compression decrease in one or several cylinders, подсос additional air in an inlet path of the engine. Zakoksovyvanie systems of release or damage of neutralizer of the fulfilled gases.
2. Malfunction of the power supply system — a contamination of atomizers, the fuel filter and hoses of system of giving of fuel. Insufficient giving of a gasoline pump. Application of bad quality fuel.
3. Malfunction of system of ignition — spark plug failure, breakdown of a high-voltage chain of system.
4. Malfunction of a control system of the engine — refusal of gauges of system. At refusal of any gauge the electronic block of management passes to work under the reserve program, allowing to reach to garage or car-care centre, but in this case decrease мощностные and economic characteristics of the engine.
5. Proslipping of coupling owing to deterioration or adjustment infringement.
6. Malfunction of brake system — притормаживание one or several wheels during movement, wrong adjustment of a lay brake.
7. Insufficient pressure of air in tyres.
8. A car overload.
Highly skilled masters with application of the special diagnostic equipment should spend full diagnostics of the car, therefore address in car-care centre.
It is independently possible to spend following works.
1. Check up and finish to norm pressure of air in tyres.
2. Check up work of working brake system and a lay brake. To remove wheels for this purpose it is unessential. Find an equal site of road and to dry windless weather spend arrival on definition выбега the car. The car should be completely filled, in salon only the driver. Disperse the car to 50 km/h, level speed, and then switch off transfer and move by inertia to a full stop. Make one more arrival in the opposite direction. Выбег should make about 500 m.
3. Check up work of system of ignition as it is described above.
4. Check up coupling work. Initial check spend on an equal, free platform from obstacles. An accelerator pedal establish the raised frequency of rotation of a cranked shaft in an idling mode — approximately 1500 mines-1. Brake the car a lay brake. Squeeze out coupling and include I transfer. Then start to release a coupling pedal smoothly. If the engine decays, coupling regularly and does not slip. If the engine not глохнет, coupling is worn out and demands replacement or adjustment of a drive of deenergizing.
