Sample Tamil Nadu HSE Second Year Basic Automobile Engineering Practice Questions

Try these sample questions to review concepts for the Tamil Nadu HSE Second 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.

1In a four-stroke petrol engine, one complete working cycle requires how many crankshaft revolutions?
A.Two revolutions
B.One revolution
C.Three revolutions
D.Four revolutions
Explanation: A four-stroke cycle comprises intake, compression, power, and exhaust. Each stroke is half a crank revolution, so four strokes need two full crankshaft revolutions.
2Stroke length of a reciprocating engine is the:
A.Diameter of the piston
B.Distance between TDC and BDC of piston travel
C.Length of the connecting rod only
D.Circumference of the flywheel
Explanation: Stroke is the linear distance the piston travels between top dead centre (TDC) and bottom dead centre (BDC). Together with bore it determines swept volume.
3Compression ratio of an engine is best defined as the ratio of:
A.Swept volume alone to zero
B.Clearance volume to swept volume
C.Total cylinder volume at BDC to clearance volume at TDC
D.Bore diameter to stroke length
Explanation: Compression ratio CR = (Vs + Vc)/Vc, where Vs is swept volume and Vc is clearance volume — equivalently total volume at BDC divided by volume at TDC.
4In a spark-ignition (SI) engine, combustion is initiated by:
A.Injector pilot fuel without air compression
B.Compression heat alone without a spark
C.A glow plug as the only ignition source
D.A high-tension spark at the spark plug
Explanation: SI petrol engines ignite a premixed charge with an electric spark at the plug near the end of compression. Compression-ignition diesels rely on hot compressed air plus injected fuel.
5In a compression-ignition diesel engine, fuel mainly ignites because:
A.High compression heats the air above the fuel auto-ignition temperature
B.A magneto supplies continuous spark to all cylinders
C.A carburettor enriches a petrol mixture
D.A spark plug fires every compression stroke
Explanation: Diesel engines compress air only to a high ratio so air temperature becomes high enough that atomised fuel auto-ignites when injected near the end of compression.
6The component that converts reciprocating piston motion into rotary crankshaft motion is the:
A.Camshaft
B.Connecting rod
C.Rocker arm
D.Push rod
Explanation: The connecting rod joins the piston (via the gudgeon pin) to the crank pin. Through the crank mechanism it converts linear piston motion into crankshaft rotation.
7Clearance volume in a cylinder is the volume:
A.Of the intake manifold plenum only
B.Swept by the piston during one full stroke
C.Remaining above the piston when it is at TDC
D.Of oil stored only in the sump
Explanation: Clearance volume is the residual chamber volume with the piston at TDC. It forms the combustion space and appears in the compression-ratio formula.
8During the power stroke of a four-stroke SI engine, the valves are normally:
A.Both fully open
B.Only the inlet valve wide open
C.Only the exhaust valve wide open
D.Both closed
Explanation: On the power stroke the charge burns and expands with both valves closed so pressure can push the piston down usefully. Valve opening is reserved for intake and exhaust events.
9The flywheel on an automobile engine mainly:
A.Stores kinetic energy and smooths torque pulses between power strokes
B.Filters contaminants from engine oil
C.Cools the radiator core
D.Increases geometric compression ratio
Explanation: A heavy flywheel stores rotational energy and releases it between power impulses, reducing speed fluctuation. In manuals it also provides a friction face for the clutch disc.
10Compared with a four-stroke engine of similar displacement, a two-stroke engine generally produces a power stroke:
A.Once every two crankshaft revolutions only
B.Once every crankshaft revolution
C.Only every four crankshaft revolutions
D.Never, because two-strokes have no combustion
Explanation: In the two-stroke cycle a power stroke occurs once per crankshaft revolution, whereas a four-stroke produces power once every two revolutions — a key reason for high power density in two-strokes.
