Question

Varying the governor setting in an IC engine

(a) Does not vary the maximum power developed in the engine

(b) Varies the maximum torque developed by the engine

(c) Does not vary the governed range of speed in which engine runs

(d) Remains constant

I have been asked this question during an online interview.

I want to ask this question from Principles of Governor in section Governor of Farm Machinery

Answer 1

Correct choice is (c) Does not vary the governed range of speed in which engine runs

Explanation: Governor is a mechanical device which controls the speed of the engine by supplying fuel on varying load condition. When there is less load on engine speed of rotation of spindle increases and more centrifugal force acts on flyballs throwing them outwards thus sleeve moves upward and fuel supply is decreased.
