Bprotect the crankcase from overpressure in event of explosion
Cprovide cooling water circulation through the engine
Dprovide air starting pressure
AI Explanation

The correct answer is A) utilize the flow of exhaust gases to supercharge the engine. This device is commonly referred to as a turbocharger. Turbochargers use the flow of the engine's exhaust gases to drive a turbine, which in turn spins a compressor that forces more air into the engine's intake. This increases the density of the air-fuel mixture, allowing the engine to produce more power. This is a common technique used to supercharge engines and boost their performance. The other answer choices are incorrect because: B) is describing a crankcase ventilation system, C) is describing a water pump, and D) is describing an air start system, none of which are the function of a turbocharger.
