Turbocharger for passenger car gasoline applications with water-cooled bearing housing
Petrol engines, where the exhaust gas temperatures are 200 to 300 °C higher than in diesel engines, are generally equipped with water-cooled centre housings. During operation of the engine, the centre housing is integrated into the cooling circuit of the engine. After the engine's shutdown, the residual heat is carried away by means of a small cooling circuit, which is driven by a thermostatically controlled electric water pump.
is this true for exo cfe ,
There are people saying, after switching off the engine, the electrical fan is still running for a while. So I guess what Borg said is true.
