Question 164Motor Plants - QMED

The correct answer is B) power the turbocharger. The exhaust system of a turbocharged diesel engine functions to drive the turbocharger. The hot exhaust gases from the engine are directed to the turbocharger, where they spin the turbine. This in turn drives the compressor, which pressurizes the intake air and increases the engine's power output. The other options are incorrect because: A) The aftercoolers are not powered by the exhaust system. C) The exhaust system does not directly reduce the cylinder scavenge effect. D) The turbocharger is not cooled by the exhaust system, but rather by a separate cooling system.
