Which type of governing is used in petrol engine?

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.

How is governing of fuel done?

7. How is governing of fuel done? Explanation: The governing engine maintains constant speed of the engine irrespective of the load on plant. This is done by varying the fuel supplied to the engine.

What is quality governed engine?

Basically petrol enginesare quantity governing b’coz , in this case fuel is mixed in the carburetter , so to change the speed we need to control the quantity of mixture that is going in the cylinder.but diesel engines are quality governing b’coz, in this case compressed air enter in the cylinder and now to change …

How knocking can be reduced?

Because pressure and temperature are strongly linked, knock can also be attenuated by controlling peak combustion chamber temperatures by compression ratio reduction, exhaust gas recirculation, appropriate calibration of the engine’s ignition timing schedule, and careful design of the engine’s combustion chambers and …

Which cycle is mostly used in high compression engines?

The dual cycle or limited pressure cycle is a thermodynamic cycle for high-speed compression diesel and hot spot ignition engine.

Why CI engine is called quality governing engine?

Whereas a I.C diesel engine is a qualitygoverned engine b’coz compressed air goes in the cylinder , hence to change the speed , we have to control the quality of fuel injected .

What is quality and quantity governing?

In ic engine,there are two terms we often use , first is quantity governing and another is quality governing . Quantity governing is a term of ic engine. The simple meaning of this is you cannot control the fuel (air & fuel mixture) with respect to load , it can only change by varying the speed.
