How Does a Diesel Engine Work？| Diesel Engine Working Principle
Like a gasoline engine, a diesel engine undergoes four processes of intake, compression, work, and exhaust per work cycle. However, since the viscosity of diesel is larger than that of gasoline, it is not easy to evaporate, but the self-ignition temperature is lower than that of gasoline. Therefore, the formation and combustion of the combustible mixture of the diesel engine are different from that of the gasoline engine. The diesel engine sucks in the intake stroke pure air. When the compressio...

2 Important Points about the Pump Inlet and Outlet – Better Technology CO., LTD.
First: The Inlet and Outlet Size of Pump and Pipe
Pump Inlet is generally larger than the outlet, because of the low pressure of inlet, water density is small, flow is slow, in order to meet the water supply balance requirements and ensure that the entrance has a certain pressure head, to prevent cavitation, the inlet is larger. Pump outlet flow is fast, with the large flow of the same diameter, so the inlet is larger than the outlet. Outlet diameter large, inlet resistance, is conducive to the...
