Engine Tubro Question

I was just curious about engines with a turbo, gas or diesel, vehicle

if they have a "turbo cooler"

Re: Engine Tubro Question

Turbo's spin at tens of thousands of RPM, and this creates heat. They can be oil cooled from your engine oil or cooled from engine coolant. Without proper cooling, the bearings in your turbo will destroy themselves.

If your referring to intercooled, then that is a heat exchanger located in the air intake system between the turbo and the intake manifold. What it does, is remove heat from the incoming air. The cooler air, the denser, the more you can fit into the engine and the more power you can make!

Re: Engine Tubro Question

Earlier diesels usually didn't have intercoolers. The Ford diesel didn't have one until 1999. The GM 6.2 didn't even have a turbo, but the 6.5s are intercooled. Some cummins have intercoolers, others don't.

Some turbos lately have been using engine coolant circulated around the bearings to cool them, but for the most part, many original turbos have a low enough stress level that they are just cooled by the oil circulating through the bearing.

Let me add that they can spin to over 100,000 RPM.
