Repair and operation of the car

At suspicion that the cylinder has the lowered compression, it is necessary to check by means of the measuring instrument of a compression it in separate cylinders. On the diesel engine it is more difficult to do it as the adapter which is rolled instead of candles is required. At the same time pistons, valves or piston rings which do not hold pressure are defined. If the engine still rather new, the compression about 32,0 Bars has to be provided. Limit of wear is value of 20,0 Bars. If the compression is lower than this value, it is necessary to solve, to replace or repair the engine. Important also that, one or all cylinders have a bad compression. If, for example, the difference at separate cylinders makes 5,0 atm, maybe, that at the "bad" cylinder valves freeze up and repair only of a head of cylinders, that is repair of valves is required. It is possible also that piston rings in flutes burned that leads to pressure relief along the piston in the krivoshipno-conrod mechanism. At identical loss of a compression it is possible to judge in the majority a case wear of cylinders. For check of a compression warm the engine up to the working temperature and turn out glow plugs. Disconnect a wire from the fuel supply stop valve. Connect the device for check of a compression in compliance with the maintenance instruction of the manufacturer. The assistant has to get into the car and include approximately for 5 seconds a starter, at the same time pressing the accelerator pedal against the stop. Consistently check a compression in all cylinders and compare to a preset value. If the compression is small in one cylinder, it is possible as first aid for temporary restoration of density to fill in the corresponding medicine in a candle opening. Certificates of these products can be received at dealers in auto parts.
