1Which ideal thermodynamic cycle serves as the theoretical basis for the working of a four-stroke petrol (spark-ignition) engine?

A.Otto cycle

B.Diesel cycle

C.Carnot cycle

D.Rankine cycle

Explanation: The Otto cycle consists of two reversible adiabatic (isentropic) processes and two constant-volume (isochoric) processes. It is the theoretical thermodynamic cycle for spark-ignition (SI) petrol engines, where heat addition occurs at constant volume during spark ignition.

2What is the main function of the oil control ring fitted on an engine piston?

A.To scrape excess lubricating oil off the cylinder wall and return it to the oil sump

B.To seal high-pressure combustion gases inside the combustion chamber

C.To increase engine compression ratio during the intake stroke

D.To connect the piston directly to the crankshaft pin

Explanation: The oil scraper/control ring is positioned in the lower groove of the piston. Its primary function is to scrape excess lubricating oil from the cylinder liner wall during piston motion, preventing oil from burning in the combustion chamber while draining excess oil back into the crankcase sump.

3In engine terminology, what is defined as the distance traveled by the piston between Top Dead Center (TDC) and Bottom Dead Center (BDC)?

A.Stroke length

B.Cylinder bore

C.Clearance volume

D.Piston clearance

Explanation: Stroke length (L) is the linear distance covered by the piston as it moves from its topmost extreme position (TDC) to its bottommost extreme position (BDC) inside the cylinder liner.

4Why is a heavy flywheel mounted at the end of the engine crankshaft?

A.To store energy during the power stroke and release it during non-power idle strokes to smooth engine rotation

B.To mix fuel and air before entering the combustion cylinder

C.To pump coolant from the radiator into the cylinder jacket

D.To generate high electrical voltage for the spark plugs

Explanation: In a 4-stroke engine, power is developed only during 1 stroke out of 4 strokes (180° out of 720° crankshaft rotation). The heavy flywheel acts as a mechanical energy reservoir, absorbing kinetic energy during the power stroke and giving it back during intake, compression, and exhaust strokes, thereby minimizing rotational speed fluctuations.

5Which component provides the high-voltage electrical arc required to ignite the air-fuel mixture in a petrol engine?

A.Spark plug

B.Fuel injector

C.Glow plug

D.Thermostat valve

Explanation: The spark plug receives a high voltage pulse (15,000V to 30,000V) from the ignition system and creates an electric spark across its center and ground electrodes to ignite the compressed petrol-air mixture inside the combustion chamber.

6How is combustion initiated in a four-stroke Compression Ignition (CI) diesel engine?

A.High-pressure diesel fuel is injected into air that has been heated purely by high compression

B.An electric spark plug fires at Top Dead Center

C.A mechanical carburetor mixes fuel vapor with air before compression

D.An external gas flame ignites the intake mixture

Explanation: In a diesel engine, only air is drawn during intake and compressed to high pressures (compression ratio 14:1 to 22:1). The compression raises air temperature above diesel auto-ignition point (~500°C–600°C). Spraying diesel fuel into this hot air causes spontaneous ignition without an electric spark.

7For the same compression ratio and heat input, how do the thermal efficiencies of the Otto cycle, Dual cycle, and Diesel cycle compare?

A.Otto cycle > Dual cycle > Diesel cycle

B.Diesel cycle > Dual cycle > Otto cycle

C.Dual cycle > Otto cycle > Diesel cycle

D.Otto cycle = Dual cycle = Diesel cycle

Explanation: For a given compression ratio, heat addition at constant volume (Otto cycle) yields higher thermal efficiency than heat addition at constant pressure (Diesel cycle) because all heat is added at the peak temperature. Thus, η_Otto > η_Dual > η_Diesel for equal compression ratio.

8What is the speed ratio of the camshaft to the crankshaft in a four-stroke engine?

A.1:2 (camshaft rotates at half crankshaft speed)

B.2:1 (camshaft rotates at double crankshaft speed)

C.1:1 (camshaft rotates at equal crankshaft speed)

D.1:4 (camshaft rotates at one-quarter crankshaft speed)

Explanation: In a 4-stroke engine, a complete cycle requires two full rotations of the crankshaft (720°). However, each intake and exhaust valve must open only ONCE per cycle. Therefore, the camshaft must rotate at half the speed of the crankshaft (1:2 ratio).

9Why must a specific valve clearance (tappet clearance) be maintained in an IC engine valve mechanism?

A.To compensate for the thermal expansion of valve stem and pushrod as the engine heats up, ensuring tight valve seating

B.To allow engine oil to leak out of the combustion chamber into exhaust

C.To increase maximum engine torque at idle RPM

D.To prevent the camshaft from rotating when the engine is hot

Explanation: As the engine reaches operating temperature, valve stems and pushrods expand thermally. If zero clearance were provided when cold, the expanding valve stem would prevent the valve from fully closing against its seat when hot, causing compression loss and burnt valve seats.

10How does a typical two-stroke petrol engine transfer fresh air-fuel mixture from the crankcase to the combustion cylinder?

A.Through the transfer port when uncovered by the downward moving piston

B.Through overhead intake valves controlled by a pushrod

C.Via an external high-pressure supercharger blower

D.Through the exhaust port during the compression stroke

Explanation: A 2-stroke engine uses cylinder ports (intake, transfer, exhaust) instead of poppet valves. As the piston moves downward during the power stroke, it first uncovers the exhaust port and then the transfer port, allowing fresh charge pre-compressed in the crankcase to enter the cylinder.
