Question 154Motor Plants - 1st Asst/Chief70% to pass
In a two cycle diesel engine, a Roots-type blower is usually_______________.
AI Explanation
The correct answer is A) gear driven by the engine.
In a two-cycle diesel engine, the Roots-type blower is typically gear-driven by the engine. This arrangement allows the blower to provide the necessary air charge for the engine's combustion process. The blower is mechanically coupled to the engine's crankshaft, ensuring that the blower's speed and operation are synchronized with the engine's operating cycle.
The other options are incorrect because: B) a separate motor would not be directly coupled to the engine's operation, C) the intake valves do not directly actuate the blower, and D) the blower is not driven by an exhaust gas turbine, which is a different type of forced induction system.
