Sample RBSE Prav Voc Automotive Practice Questions

Try these sample questions to test your RBSE Prav Voc Automotive exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In a four-stroke spark-ignition engine, the power stroke occurs when:
A.The intake valve opens and air alone enters the cylinder
B.Compressed air–fuel mixture is ignited and expanding gases push the piston down
C.The exhaust valve stays closed and no combustion takes place
D.Only the starter motor turns the crankshaft without combustion
Explanation: On the power (expansion) stroke, the spark plug ignites the compressed mixture; high-pressure gases drive the piston downward, producing useful work.
2The primary job of the clutch in a manual-transmission vehicle is to:
A.Cool the radiator automatically during highway driving
B.Temporarily disconnect engine torque from the gearbox during gear changes and starts
C.Generate high-voltage sparks for the spark plugs
D.Measure tyre pressure at each wheel hub
Explanation: The clutch couples and uncouples engine torque to the transmission so the driver can start from rest and shift gears smoothly without grinding gears.
3Which component stores chemical energy and supplies electrical energy when the engine is not running?
A.Radiator core
B.Lead-acid battery
C.Fuel pump only
D.Exhaust muffler
Explanation: The battery stores chemical energy and provides electrical power for starting, lighting, and accessories when the alternator is not generating.
4Disc brakes slow a vehicle primarily by converting kinetic energy into:
A.Chemical energy stored in the fuel tank
B.Heat energy through friction at the pad and rotor interface
C.Magnetic energy in the alternator windings only
D.Sound energy only from the horn
Explanation: Friction between brake pads and rotors converts vehicle kinetic energy into heat, which is then dissipated to the surrounding air.
5Engine oil in a lubricated four-stroke engine mainly:
A.Replaces the need for coolant forever
B.Reduces friction, cools parts, and helps seal and clean internal surfaces
C.Increases tyre grip on wet roads
D.Charges the battery through the oil pump
Explanation: Lubricating oil forms films that cut friction and wear, carries heat away from bearings, aids ring sealing, and suspends contaminants for filtration.
6What does the thermostat in a liquid-cooled engine control?
A.The opening and closing of the fuel filler cap
B.Coolant flow between the engine and radiator to help manage operating temperature
C.Cabin seat height adjustment only
D.Tyre rotation schedule in kilometres
Explanation: The thermostat restricts coolant flow until the engine warms, then opens to allow flow through the radiator so the engine stays near its designed temperature range.
7The alternator’s main function while the engine is running is to:
A.Compress intake air for the turbo only
B.Generate electricity to power systems and recharge the battery
C.Meter fuel into each cylinder
D.Hold the parking brake on steep slopes
Explanation: Driven by the engine, the alternator produces electrical power for loads and restores charge to the battery after starting and during operation.
8Shock absorbers (dampers) in the suspension system primarily:
A.Increase engine horsepower at high rpm
B.Control spring oscillations and improve tyre contact with the road
C.Filter fuel before it reaches the injectors
D.Raise battery voltage above 24 V on 12 V systems
Explanation: Dampers dissipate energy from spring bounce so the vehicle settles quickly and the tyres stay in better contact with the road for control and comfort.
9In a typical light vehicle, the differential allows:
A.Both drive wheels to always spin at exactly the same speed in every turn
B.Drive wheels to rotate at different speeds when cornering
C.The engine to run without any lubrication
D.The radiator to empty automatically on every stop
Explanation: When cornering, the outer wheel travels a longer path than the inner wheel. The differential permits different wheel speeds while still transmitting torque.
10Spark plugs in a petrol engine are designed to:
A.Ignite the compressed air–fuel mixture at the correct time
B.Pump coolant through the cylinder head
C.Measure exhaust oxygen concentration only
D.Lock the transmission in park
Explanation: Spark plugs provide the high-voltage spark that ignites the compressed mixture at the scheduled crank angle for efficient combustion.
