REASON
|
WAY OF ELIMINATION
|
|
The shaft of the engine rotates ovally, high fuel consumption, low engine capacity
|
| Nozzles are faulty | Replace nozzles. |
| Nozzles are not tight (drops), are polluted | Replace nozzles. |
| The nozzle needle hanged or is broken | Replace a nozzle needle. |
| The beginning of giving of the pump is displaced | Check adjustment of the beginning of giving of the pump. |
| The fuel pump of a high pressure is faulty | Establish the new pump of a high pressure. |
| The engine has mechanical defect; valves are not tight, cylinders / pistons are worn-out, laying of a head of the block of the cylinder, narrowing in an exhaust system is not tight | Check a compression, check the engine mount / bearing of a shaft of the engine. |
|
Malfunctions at work in an idling mode
|
| Heavy course of a cable by pressing of a pedal of an accelerator | Adjust a cable of management of gas so that it easily moved. |
| Oval moving of a shaft of the engine when idling and the cold engine, too high frequency of rotation at the warm engine | Check vacuum hoses for increase of frequency of rotation in an idling mode. |
| Are not fixed топливопроводы on the fuel pump of a high pressure and the fuel filter / are faulty топливопроводы | Check rigid landing, if necessary replace the pipeline. |
| Screw connections on the fuel pump of a high pressure are weakened | Check a basic plate on cracks or a break, if necessary replace the pipeline. |
| The system of supply of fuel is faulty | The fuel filter is polluted, fuel drain hydrolines and топливопроводы a high pressure or the ventilating line of a fuel tank are not tight or polluted, bent or narrowed in junctions. |
|
Too high fuel consumption
|
| The air filter is polluted, the power supply system is not tight | Clear or replace filtering element. Check visually tightness of all топливопроводов (inlet, drain, топливопроводов a high pressure, the fuel filter and the fuel pump of a high pressure). |
| The drain hydroline is littered | Weaken on the fuel pump of a high pressure the drain hydroline. Start the engine and check, whether fuel acts. Blow air the drain hydroline from the fuel pump of a high pressure to a fuel tank. |
| Too high frequency of rotation of a shaft of the engine when idling | Check frequency of rotation of a shaft of the engine when idling and possibility of its decrease. |
|
Too low engine capacity
|
| Verifying preconditions: indications of a speedometer should be normal; the size of tires to correspond to serial equipment; wheels (brakes, bearings, naves of wheels) should be blocked, coupling and a drive of management of coupling should be in a normal state; process of a running in should be complete. Speed should not decrease at additional equipment (luggage on a roof etc.). For determination of the maximum speed it is recommended to pass an equal test site in both directions, about 1000 meters to define the maximum speed by means of a stop watch. |
| The emphasis of the lever of the butterfly valve limiting its maximum opening is not reached | Adjust a cable of management of a butterfly valve. |
| The air filter is polluted | Clear or replace filtering element. |
| Air vials in топливопроводе from the filter to the fuel pump / the fuel pump of a high pressure | Check submitting топливопровод and the filter. The fuel filter is not fixed or is not tight; it is not tight submitting топливопровод between a tank and the fuel filter; linear connections on the fuel filter are not tight. |
| Are faulty топливопроводы | Check visually tightness of all топливопроводов (inlet, drain, топливопроводов a high pressure) from the fuel filter and the fuel pump of a high pressure. |
