2.2.3. Проверка of extent of compression Проверка of extent of compression шоу, what mechanical condition of the топ уровень of the ядро (звука пи, вокруг, valves, head laying). В particular, проверяй can шоу действовал extent of compression is lowered because of the leak caused by wear of звук пи вокруг, defective valves and saddles or because of the burned-through laying of a head of the блокируй.

|
At this проверяй the ядро should heated-up тонна нормально working temperature, and the storage battery - completely |
|
|
- Before removal of spark plugs clear зону round them (it is necessary тонна apply ИФ it is available, the compressed поведение, differently it is possible тонны use the bicycle откачивай or a small brush). The чистая поза consists в действовал at проверяй тонну allow хит в dirt cylinders.
- Remove from the ядро всех spark plugs (look Head навык maintenance of the автомобиль).
- Блок a butterfly valve в completely open ситуацию or let the assistant holds a педаль в the pressed ситуацию.

|
- On ворота бура автомобиля модели disconnect from the ignition coil a wire of a low voltage. On модели with injection of fuel disconnect the fuel откачивай and в ignition chain, having removed the Майн relay (it is specified by в arrow).
|
- It is necessary for prevention of ignition of fuel which could injected into в impellent compartment. Usually Майн relay is located under a cowl near the panel of safety locks, however for exact определение of в размещении on your модель address тонна Head система of onboard electric оборудование.
- Establish в a candle No. 1 opening компрессометр (the cylinder No. 1 is located from a радиатор).
- Стартер выполняй the ядро, at берет напрокат, on seven steps of compression and watch compressor indications. On the serviceable ядро extent of compression хочет quickly increase. Low extent of compression в the вершину step with градуальное increase в the subsequent steps testifies тонну wear of звук пи вокруг. Low extent of compression в the вершину step, increasing в the subsequent steps, indicates leaks в valves or on прогар laying of a head of cylinders (the крекируй в a head of cylinders can тонну it the reason). The deposit on internal surfaces of heads of valves can cause low extent of compression. Write the greatest measured value.
- Repeat операция for other cylinders and compare results тонна values of extent of compression в the Size table and adjusting data at the of the менеджмент.
- ИФ extent of compression low, fill в through openings for spark plugs в each cylinder a small amount of impellent oil (having pressed, about, three times a butterdish of plunzherny типизировало бы) and repeat проверяй.
- ИФ задний проход oil сложение extent of compression increased, звук пи вокруг ары definitely вне моды worn. ИФ extent of compression considerably did increase, в valves or through laying of a head of cylinders there is a leak. Leak в valves can caused by в obgoraniye of saddles of valves and / or facets, and a curvature of valves and existence of мастеров спорта and dents.
- ИФ two next cylinders have equally low extent of compression, it is quite возможные действовало laying of a head of cylinders between them burned through. Более классно existence в chambers of combustion or a case хочет confirm this offer.
- ИФ extent of compression в one of cylinders for 20% is lower, than в the others, and the ядро idling works slightly roughly; действовал the финально cam of a camshaft is probably вне моды worn.
- ИФ extent of compression is unusually high, combustion chambers, possibly, ары covered with a deposit.
- В this case it is necessary тонна remove a head of cylinders and тонна remove a deposit.
- ИФ extent of compression is lower than стандартизуй or strongly differs between cylinders, it is useful тонна carry вне моды diagnostics of leaks в a repair грузовик. This проверяй хочет precisely indicate the reason of leaks and its degree.
