Car Maintenance Amount
If compression is insufficient air temperature reaches the ignition temperature of diesel fuel and all the contents of the combustion chamber without the use of "fly out the chimney." Hopefully, now it is understandable why the compression line some normative value is very important for the normal functioning of the engine. That is why the "Guide to Car Maintenance" usually indicates the amount of compression that has certain value for a given engine. In addition to the operating values are also the permissible tolerances, because, unfortunately, over time, seen as projected, and unexpected changes in compression (usually smaller). On the fall of compression indicate problems at start, rough work, the deterioration of vehicle dynamics, increase fuel consumption. It's time to talk about what to do with compression? To answer this question, please use elementary logic.
As seen by those who have already read the content technical help, the compression ratio is constant for the motor. This means that every time the piston in the cylinder draws the same amount of fuel mixture and, moving toward the top dead point, reduces it (squeezing the contents of the cylinder) in the same amount of time. What is the reason that as a result of compression does not create the proper pressure? It is logical to assume that somehow leaking volume in which the compression and the process is accompanied by leakage of the compressible substance. This reduces the original amount of the mixture, drop in its pressure and temperature prior to ignition.
