Question 329Motor Plants - Assistant Engineer

The correct answer is B) power the turbocharger. The exhaust system of a turbocharged diesel engine functions to power the turbocharger. The hot exhaust gases from the engine are directed to the turbocharger, where they spin the turbine wheel, which in turn drives the compressor wheel to force more air into the engine's intake. This increased airflow allows the engine to produce more power. The exhaust system is a critical component that enables the turbocharger to function properly. The other answer choices are incorrect because: A) The aftercoolers are cooled by the engine's cooling system, not the exhaust. C) The exhaust system does not directly affect the cylinder scavenge effect. D) The turbocharger itself is responsible for cooling, not the exhaust system.
