Charge Air Cooler For Diesel Generator

Charge air Cooler for Diesel Generator

Function
Lowering intake air temperature: The exhaust gas from the diesel engine can heat the turbocharger and the intake air. Additionally, the compression of air by the turbocharger also generates heat. High intake air temperatures can lead to engine knocking, reducing the supercharging effect and engine life. The charge air cooler cools the compressed air, reducing the intake air temperature by about 50-60°C. This allows for an appropriate increase in the engine's compression ratio, improves low-speed power output, and increases 进气 density, thereby enhancing engine efficiency. For every 10°C decrease in intake air temperature, the engine power can increase by 3%-5%.
Reducing emissions: It helps reduce the emissions of pollutants such as CO, HC, NOₓ, and particulate matter. For example, by increasing the intake air density, it promotes more complete fuel combustion, reducing CO emissions. Lowering the intake air temperature can also control the combustion temperature, which is beneficial for reducing NOₓ emissions.

Inspection methods
Leakage and blockage inspection: Check whether the pipes and hoses of the air - to - air charge air cooler have leaks, holes, cracks, or loose connections. Also, check whether the heat sink fins of the charge air cooler are blocked by dirt and debris, and whether there are cracks, holes, or other damages.
Leakage and blockage test: For the leakage test, install on the air outlet of the intercooler, install a pressure gauge and an adjustable compressed air supply pipe with a cut - off valve on the air inlet, apply air pressure, and if the pressure drop is equal to or less than 34kPa (5psi) within 15s, the intercooler is in good condition; otherwise, there is a leak and it needs to be replaced. The temperature difference test can be used to check whether the outside of the air - to - air charge air cooler is blocked.
