Diesel Engine Oil Cooler 4990291 Parameter:

1. The intercooler plays the role of cooling air, and the high temperature air is cooled by the intercooler and then enters the engine. If the intercooler is lacking and the supercharged high-temperature air directly enters the engine, the engine will knock or even damage the flame due to the high air temperature.

2. The cooling air is obtained through the opening on the engine cover. The intercooler will only be blown by some hot air from the engine compartment. Although the heat dissipation efficiency is affected, because the intake air temperature will rise in such a situation, Therefore, the fuel consumption of the engine will drop a lot, which also indirectly reduces the working efficiency of the engine. 

3. The cooling of the engine must be moderate. If the cooling is excessive, the heat transfer loss will increase, the fuel economy of the engine will be deteriorated, and the following adverse consequences will also be caused: poor fuel vaporization and atomization, worse combustion, and increased oil viscosity at low temperatures.
