The temperature in winter is low, compared with the difficulty of starting diesel generator sets in winter in summer, the following is the reason why diesel generator sets are difficult to start in winter by gogopower.
- The viscosity of lubricating oil increases greatly at low temperature, or even solidifies, which increases the starting resistance of the engine, and cannot reach the minimum speed + (generally above 100r/min (revolution/min) required for starting the engine).
- Due to the decrease of the starting speed, the leakage of compressed air increases, and the heat dissipation of the cylinder wall increases, which greatly reduces the temperature and pressure of the air at the end of compression, which increases the delay period of diesel ignition, and even can not burn in severe cases.
- The viscosity of diesel oil at low temperature increases, which reduces the injection speed. In addition, the swirl speed, temperature and pressure of the air at the end of compression are relatively low, so that the atomization quality of the diesel injected into the cylinder is poor, and it is difficult to form quickly with the air. A good combustible gas will ignite and burn in time, or even fail to catch fire, resulting in difficulty in starting.
The above content is why diesel generator sets are difficult to start in winter, and I hope to be helpful to everyone.
