If you have a Cummins diesel power generator, maybe you meet some problems in diesel engine, today Starlight will tell you some common problems and causes. 1.Why diesel engine starts up more difficult in winter? Start-up of diesel engine, not only depends on itself technical situation, but also is influenced by ambient air temperature. Here is the reason as follows: A.In winter, the climate is cold, the ambient temperature is low, the oil viscosity increases, and the friction resistance of the moving parts increases, which reduces the starting speed and makes it difficult to start; B.The capacity of storage battery decreases with the decrease of temperature, which further reduces the starting speed; C.Because of low speed of start-up, leakage of compressed air increasing and heat dissipation of cylinder wall increasing, the temperature and pressure of air at the end of compression are greatly reduced, and the delay period of diesel ignition is increased, even ...
