- Turbo charge engine
- IC engine
- Dual charged engine
- None of these
- d
-
Engine does not send air pressure into the cylinder.
It creates low pressure area inside the cylinder and high pressure air outside the engine.

What is the function of water body?
- To provide water
- To regulate water
- To cool engine
- To use water
- b
-
Water Body is also called Water Pump.
It pumps the water / coolent from radiator to engine.
If it damaged, it will directly damage the head of the engine.
What is function of shaft?
- Rotate the engine
- Rotate the clutch
- Rotate the axle
- Transmit the power
- d
-
Shaft transmit power from one part to another.
How many valves available on single piston?
- 2
- 4
- Both A & B
- 5
- c
-
A single piston in an engine works with a cylinder.
The number of valves depend on the design and configuration of engine.
Some engines have two valves (one for intake and one for exhaust) and some have four valves (two for intake and two for exhaust).
Intake Valves allow the fuel and air mixture in the cylinder.
Exhaust valves exit the gases from cylinder after combustion.
How many rings available in engine piston?
- 1
- 2
- 3
- 4
- c
-
The top two rings are called “Compression Rigs”.
The bottom ring is called “Oil Controlling Ring”.
What is function of axle in vehicle?
- Provide speed to wheels
- Rotates the shaft
- Rotates the wheels
- None of these
- c
-
An axle is a shaft or rod which is connected with a pair of wheel.
Axle rotates the vehicle wheels an supports the weight of vehicle.
Engine applies force to the axle which rotates the wheels and moves the vehicle forward.
There are three types of axles in vehicles which are Front Axle, Rear Axle and Stub Axle.
What is function of Governor in engine?
- Control the fueling
- Control the speed
- Control the pressure
- Control the vibration
- b
-
Governor controls the engine speed or maintain the speed.
When a load is applied on engine, its speed decreased. In this situation, the Governor maintain the engine speed or RPM.
There are two types of Governors i.e. Centrifugal Governor and Inertia Governor.
