More and more operators not only need to install supercharger, but also require the installation of intercooler, after all, the knowledge of friends is more and more rich.
Many machine operators say that the turbocharger is afraid of the engine can not stand, easy to break, so do not dare to install, so today say the engine can not stand, easy to break. After the turbocharger is installed, the engine horsepower increases, the crankshaft, connecting rod, cylinder liner, piston and other parts of the engine are stressed. More importantly, the supercharger discharge air temperature is high, the intake gas is large, and it is directly sent to the engine intake pipe, which is easy to cause knock, that is to say, the engine is easy to break.
Intercoolers are usually only seen in cars with turbo charges. Because the intercooler is actually a turbocharged accessory, its role is to improve the efficiency of the engine air exchange.
The influence of high temperature gas on the engine is mainly in two points: first, the air volume is large, equivalent to the engine suction air is less; And the second point is more important, high temperature air is particularly bad for engine combustion, power will be reduced, emissions will become bad. Under the same combustion conditions, the engine power will decrease by about 3% to 5% for every 10 ℃ increase in the temperature of pressurized air. This problem is very serious. The increased power will be offset by the high air temperature. In order to solve these problems, we need to cool the pressurized air again before sending it to the engine. The part that undertakes this heavy duty is the intercooler.
Intercoolers are generally made of aluminum alloy materials. According to the different cooling medium, common intercoolers can be divided into two kinds.
One is through the vehicle driving head-on into the cold wind cooling, namely, air cooling;
The other is just the opposite of air cooling. Is to put a cooler (the shape and principle of the air cooled intercooler is basically the same) into the intake pipe, let the pressurized hot air flow through. In the cooler, there is a constant flow of cooling water, which takes away the heat of the pressurized air, or water cooling
