Question 164Motor Plants - QMED
70% to passThe exhaust system for a turbocharged diesel engine functions to _______________.
Apower the aftercoolers
Bpower the turbocharger
Creduce the cylinder scavenge effect
Dcool the turbocharger
AI Explanation
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.
