Jichai Diesel Generator Supercharged Intercooling System

Sep. 21, 2022

Jichai diesel generator supercharging and intercooling system is mainly composed of left and right intake and exhaust pipes, left and right superchargers, left and right intercoolers and related pipelines. When supercharging, the air is compressed, and the temperature and pressure are increased at the same time. If the intercooling technology is adopted, the density of the intake air can be increased. If the intercooling technology is not used, the intake air density will be limited by the adiabatic efficiency of the compressor. Below, Starlight Power Generation Equipment will explain the working principle of the supercharged and intercooling system of Jichai diesel generator in detail.

Nowadays, YC12VC series diesel engines for power generation all adopt an independent supercharged intercooling system, and Jichai diesel generators are no exception. When the engine is working, the waste from the exhaust pipe of the engine enters the turbine and the heat can make the full wheel rotate, and make the compressor with the lubricating wheel to rotate. The compressed air enters and compresses the air, and then enters the engine intake pipe through a pipe, and the cold expanded exhaust gas leaving the turbine is led by the turbine casing to the engine exhaust system and enters the atmosphere. After the intake air is compressed, the density of the air charged into the cylinder is increased, and with the good cooperation of the oil supply system, more fuel can be fully burned, the power is increased, and the economy is improved. The supercharged intercooling is to cool the compressed air to further increase the air density and increase the intake air volume, thereby further improving the power and reducing the temperature of the combustion chamber.


To increase the output power of Jichai diesel generator, the most economical and effective way is to increase the air volume entering the cylinder. Under the condition that the volume of the cylinder of Jichai diesel generator remains unchanged, increasing the density of the air entering the cylinder is the most important means. However, the density of the air is proportional to the pressure and inversely proportional to the temperature. Therefore, increasing the pressure of the intake air and reducing the temperature of the intake air can increase the intake air density. At present, diesel generators generally use superchargers. To increase the pressure, use the intercooler to reduce the temperature of the gas.


At present, medium and high voltage diesel generators are generally equipped with intercoolers. The intercooler is actually a heat exchanger, which is installed between the turbocharger and the combustion chamber. When the supercharger of the Cummins 300KW diesel generator supercharger is relatively high, the intake air temperature is relatively high, which reduces the density of the air. The intercooler is used to cool the charge air and reduce the temperature of the intake air after supercharging. Charge air can generally be lowered by 25 to 60°C in the intercooler. On the one hand, the density of the charge can be increased, and on the other hand, the cylinder temperature of the intake air and the average temperature of the entire cycle can be reduced.
