There are more and more small displacement turbine engines. How does the turbine cool the hot air?

The turbine will make the cold air hot. It can't be used directly by the engine. It must be cooled in the intercooler and sent to the front of the valve by the oncoming wind. However, the pipeline is too long and the throttle response is slow. (turbine engines)

With the increasing number of small-displacement turbine engines, intercoolers are becoming more widespread, because the turbine blades pressurize cold air at high speeds, increasing the density of the air and heating it, but not the oxygen content. Low hot air is used directly to the engine (which can cause knock) and requires an intercooler to cool down.

Some original turbine engines are equipped with water-cooled intercoolers that use the constant temperature of the water to control the intake air temperature, helping to avoid overheating in the city where the traffic jam occurs.

The intercooler is also constructed with fins. The hot air from the turbine enters the intercooler. After the oncoming wind is used to accelerate the heat dissipation of the air, the cold air flows from the outlet to the intake line and the intake manifold. The pipe is supplied to the engine. In theory, the larger the intercooler, the better the cooling efficiency, but the disadvantage is that the pressurized air is weakened. Before the intake valve, sufficient pressure is established again until the pressure relief valve is opened, causing the throttle response to be slow and half beat. It is also a common turbo delay. Therefore, the development of water-cooled intercoolers is to shorten the intake line and improve the throttle response, especially when the city stops.
