How to check the compression in the engine?

There are times when the car starts to vibrate, reduced engine power, increased fuel and oil. In this case, be sure to pay attention to the engine cylinders, which ceased to function properly. On how to properly check the compression in the engine, tell that story. Reduced pressure in the cylinders, primarily due to the leakage of the pressure that occurs due to a number of circumstances. First, it can be formed valve clearance, and secondly, damaged piston rings, and thirdly, you may need to replace the candles. You have changed the spark, and it is no effect? Then, to determine the causes of leakage of pressure you need to use compressometer to determine the compression in the engine car. Compression - a measurement of maximum cylinder pressure, which occurs when idling motor starter. A compressometer represents equipment that resembles a pressure gauge, connected to a hose with a nipple and check valve. Compressometer readily available in financial instrument. It does not require time-consuming and easy to use. Manufacturers offer two types of compressometer. Some compressometer can twist into place candles (at the time of diagnosis), other compressometer require the retention of power. It is recommended to measure the pressure of having Shiftmen. How to check the compression in the engine car. Initially, ask your assistant to take the driver's seat. Let it will turn off the engine and gearbox set to "neytralku. Then you must remove the candle, but before that check the lid, forming a contact with high voltage wires. This is necessary not to forget what the candle is associated with a particular wire. Tangles postings may result in failure of the engine. Previous candles are placed so that they are not dirty and dusty. In addition, you should pay attention to the sequence in which you removed the candle. It is very important, because after diagnosis, without the hassle, you can once again regain their former place. After performing all these actions, tell your Shiftmen that he has set in motion a starter. And so seven times. Further your actions are as follows: you put a candle in the hole compressometer first cylinder; your Shiftmen sets in motion the engine with the starter. Do not forget that compressometer should form an indissoluble contact with the candle hole. Starter scrolls at least seven times, follow the indications compressometer. In a normally functioning engine pressure rises instantaneously. But in grinding of piston rings will experience a slow and gradual increase in compression. Pressure does not appear to be if worn cylinder head gasket, or gaps formed in the cylinder head. Fall of compression may be related to the accumulation on the disks of various valve deposits; register the highest data unit, then all data must reset the; entire operation carried out for the first cylinder, conduct and respect the other two cylinders, and if at the time of diagnosis you have received too little data it is recommended to pour motor oil in the engine cylinders through the spark hole. Enough for one tablespoon for each cylinder. Then re-measure the compression. If you fail out piston rings, the addition of engine oil must increase the pressure. But in the case where the compression is low, you should check the valves on the existence of a leak, as well as draw attention to the tightness of gaskets cylinder heads. Low compression pressure in all three cylinders can conceive that destroyed the unity of the rubber strip that connects all the cylinders together. Reduced compression at 15%, at least one of the cylinders, notifies you wear drive cams valves. After removing all the problems that screw into place the candles in the order in which you take them off. Then ride the car a short time in order to restore the customized settings. But if the diagnosis of the car at home, you will systematically get low, then the car is recommended to ward off the service station.
