Sample Tamil Nadu HSE First Year Basic Automobile Engineering Practice Questions

Try these sample questions to review concepts for the Tamil Nadu HSE First Year Basic Automobile Engineering exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1An internal combustion (IC) engine produces mechanical work mainly by:
A.Burning fuel inside the engine cylinders to expand gases and move pistons
B.Using only electric motors with no chemical fuel
C.Absorbing heat from ambient air without any fuel
D.Storing compressed air only without combustion
Explanation: In an IC engine, fuel burns inside the cylinder; high-pressure expanding gases push the piston and produce work at the crankshaft.
2Top dead centre (TDC) of a piston is the position when the piston is:
A.Nearest to the crankshaft (bottom of stroke)
B.Halfway between top and bottom of the stroke
C.At the outermost (highest) end of its travel in the cylinder
D.Outside the cylinder completely
Explanation: TDC is the extreme upper position of piston travel; BDC is the extreme lower position nearest the crankshaft.
3Bottom dead centre (BDC) is the piston position:
A.At maximum distance from the crankshaft centreline
B.At the lowest end of piston travel nearest the crankshaft
C.When both valves are fully open only
D.When the spark plug fires in a diesel
Explanation: BDC is the lower extreme of piston travel. From BDC the piston rises toward TDC on the compression or exhaust stroke depending on the cycle.
4The four strokes of a four-stroke engine cycle, in correct order, are:
A.Power, intake, exhaust, compression
B.Intake, compression, power (expansion), exhaust
C.Compression, exhaust, intake, power
D.Exhaust, power, intake, compression
Explanation: Standard four-stroke sequence: intake → compression → power → exhaust, then the cycle repeats.
5Bore of an engine cylinder means the:
A.Length of the connecting rod
B.Diameter of the cylinder (piston diameter)
C.Volume of the crankcase only
D.Thickness of the cylinder head gasket
Explanation: Bore is the cylinder’s internal diameter (essentially the piston diameter). Stroke is piston travel between TDC and BDC.
6Petrol engines used in cars are generally classified as:
A.Spark-ignition (SI) engines
B.Compression-ignition only with no spark
C.Steam engines with external boilers
D.Gas turbines with continuous combustion only
Explanation: Conventional petrol engines ignite a premixed charge with a spark plug and are called spark-ignition (SI) engines.
7Diesel engines used in automobiles are generally:
A.Spark-ignition engines with carburettors only
B.Compression-ignition (CI) engines
C.External combustion engines
D.Stirling engines
Explanation: Diesel engines compress air to high temperature and inject fuel so it auto-ignites — compression-ignition (CI).
8The piston in a reciprocating engine mainly moves:
A.In a continuous rotary path like a turbine blade
B.Up and down (reciprocating) inside the cylinder
C.Only sideways across the cylinder wall
D.Outside the engine block in free air
Explanation: Pistons reciprocate between TDC and BDC; the connecting rod and crank convert that motion to rotation.
9Engine oil in the lubrication system primarily helps to:
A.Increase friction between moving parts
B.Reduce friction, remove heat, and help clean and seal moving parts
C.Replace the need for coolant in all engines
D.Ignite the fuel–air mixture
Explanation: Lubricating oil reduces friction and wear, carries heat away from bearings and pistons, helps suspend contaminants, and assists piston-ring sealing.
10A common purpose of the engine cooling system is to:
A.Keep the engine at a safe operating temperature and prevent overheating
B.Increase combustion temperature without limit
C.Freeze the coolant solid during normal running
D.Remove all lubrication from bearings
Explanation: Cooling systems remove excess heat so the engine stays near design temperature, protecting parts and maintaining efficient combustion.
