Question

When the load on the engine increases, it becomes necessary to increase the supply of working fluid and when the load decreases, less working fluid is required. The supply of the working fluid to the engine is controlled by a

(a) D-slide valve

(b) governor

(c) Meyer’s expansion valve

(d) flywheel

This question was addressed to me by my school principal while I was bunking the class.

My question is from Reversing Gears topic in portion Steam Engine Valves and Reversing Gears of Machine Dynamics

Answer 1

The correct choice is (b) governor

The best I can explain: When the load on the engine increases, it becomes necessary to increase the supply of working fluid and when the load decreases, less working fluid is required. The supply of the working fluid to the engine is controlled by a governor.

Flywheel controls the speed variation caused by the fluctuations of the engine turning moment during each cycle of operation.
