Pick up the false statement

Answer & Solution
Correct Answer: Option D
In this system of governing, the quality of charge (i.e. air-fuel ratio of the mixture) is kept constant. But the quantity of mixture supplied to the engine cylinder is varied by means of a throttle valve which is regulated by the centrifugal governor through rack and pinion arrangement.

Carburated Petrol Engine uses Quantitative Governing. Carburated Petrols use Quantitative Governing since Air Fuel Quality is pre-determined & varying quantity through Throttle Valve determines combustion.

Whereas Diesels works on Excess Air Cycle & varying Quality of Fuel Air mixture inside the cylinder determines combustion.
