Detailed Product Description: | Nanjing diesel generator rental | compression process compression process: To make sucked into the cylinder of the combustible mixture can burn rapidly to produce a greater pressure, so that the engine is higher power, you must burn combustible mixture before compression, it reduce the volume, density increased, temperature, that needs to have the compression process. In this process, the intake and exhaust valves closed, crankshaft pushes the piston from the bottom dead point ended up moving one stroke, namely compression stroke. At this point the mixture pressure will increase to 0.6-1.2MPa, temperature up to 600-700K. In this journey there is a very important concept, that is, the compression ratio. The so-called compression ratio, that is, before compression, the maximum volume of gas in the cylinder and the compression ratio of a minimum volume. Normal compression ratio increases, the end of the compression pressure and temperature of the mixture will be higher, the combustion speed is faster, and thus the power of engine is larger, better economy. General car compression ratio between 8-10, but now the latest listing of Polo reached 10.5 high compression ratio, so it's relatively good performance of torque. However, the compression ratio is too large, not only can not be further improved combustion, deflagration, and it will appear abnormal combustion such surface ignition phenomenon.
