Sample Assam ASSEB Higher Secondary Skill Subject Automotive Practice Questions

Try these sample questions to review concepts for the Assam ASSEB Higher Secondary Skill Subject Automotive exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In a four-stroke petrol engine, during which stroke does the spark plug ignite the compressed air-fuel mixture?
A.Power stroke
B.Compression stroke
C.Suction stroke
D.Exhaust stroke
Explanation: Ignition occurs near the end of the compression stroke, initiating rapid combustion that forces the piston down during the power stroke.
2Which engine component converts the reciprocating linear motion of the piston into rotational motion?
A.Camshaft
B.Crankshaft
C.Flywheel
D.Connecting rod
Explanation: The crankshaft converts the up-and-down (reciprocating) motion of pistons into rotational torque transmitted to the flywheel and drive train.
3What is drawn into the cylinder during the intake (suction) stroke of a four-stroke diesel engine?
A.Air and petrol mixture
B.Air and diesel mixture
C.Air only
D.Diesel spray only
Explanation: Unlike petrol engines which intake a fuel-air mixture, a diesel engine inducts only pure air during its suction stroke.
4What is the primary function of the thermostat valve in an automotive liquid cooling system?
A.To pump coolant to the engine block
B.To cool down the engine oil inside the oil sump
C.To filter rust particles from the coolant
D.To maintain engine operating temperature by controlling coolant flow to the radiator
Explanation: The thermostat remains closed when the engine is cold to allow rapid warmup, and opens at preset temperatures to permit coolant flow through the radiator.
5Which component in a forced-feed engine lubrication system draws oil from the oil sump and delivers it under pressure to bearings?
A.Oil pump
B.Oil strainer
C.Dipstick
D.Baffle plate
Explanation: The positive displacement oil pump (gear or rotor type) pressurizes engine oil and distributes it to the crankshaft, camshaft, and rocker arm bearings.
6What term describes the process of clearing exhaust gases from a two-stroke engine cylinder using fresh air-fuel mixture?
A.Supercharging
B.Scavenging
C.Turbocharging
D.Carburetion
Explanation: Scavenging is the process in two-stroke engines where incoming fresh charge pushes out burned exhaust gases through the exhaust port.
7In a four-stroke internal combustion engine, what is the speed ratio between the camshaft and the crankshaft?
A.Camshaft rotates at twice crankshaft speed (2:1)
B.Camshaft rotates at equal speed to crankshaft (1:1)
C.Camshaft rotates at half crankshaft speed (1:2)
D.Camshaft rotates at one-fourth crankshaft speed (1:4)
Explanation: In a 4-stroke cycle engine, each valve opens once every two crankshaft revolutions, so the camshaft gear has twice as many teeth and turns at half crankshaft speed (1:2).
8What is the primary function of the compression rings fitted on an engine piston?
A.To scrape excess oil off the cylinder wall
B.To align the connecting rod with the crankshaft journal
C.To lock the gudgeon pin inside the piston boss
D.To seal the combustion chamber and prevent blow-by of combustion gases into the crankcase
Explanation: Compression rings seal the high-pressure gas above the piston to prevent blow-by into the crankcase and transfer heat from piston to cylinder wall.
9How does the compression ratio of a compression-ignition (diesel) engine compare to that of a spark-ignition (petrol) engine?
A.Diesel compression ratio (14:1 to 22:1) is significantly higher than petrol (6:1 to 10:1)
B.Diesel compression ratio (6:1 to 8:1) is significantly lower than petrol (14:1 to 18:1)
C.Both petrol and diesel engines operate at an identical 10:1 compression ratio
D.Diesel compression ratio varies continuously between 2:1 and 4:1 depending on load
Explanation: Diesel engines rely on high heat generated by air compression to self-ignite fuel, requiring high compression ratios (14:1 to 22:1) compared to petrol engines (6:1 to 10:1).
10In the engine oil specification SAE 15W-40, what does the letter 'W' stand for?
A.Weight
B.Winter
C.Waterproof
D.Withstand
Explanation: The 'W' in multi-grade oils stands for 'Winter', indicating cold-start flow rating at low temperatures alongside high-temperature viscosity (40).
