1In a four-stroke spark-ignition engine, the power stroke begins when:
A.The spark plug ignites the compressed air–fuel mixture near the end of the compression stroke
B.The exhaust valve opens fully at BDC only
C.Only the cooling fan starts rotating
D.The battery is disconnected from the alternator
Explanation: Near the end of the compression stroke the spark ignites the charge; expanding gases force the piston down on the power stroke. Exhaust-valve timing, the cooling fan, and battery disconnection are not what starts combustion power.
2Compared with a four-stroke petrol engine, a two-stroke petrol engine generally:
A.Completes a power cycle in two piston strokes (one crankshaft revolution) and often uses ports instead of a full valve train
B.Always requires four crankshaft revolutions per power stroke
C.Cannot use petrol as a fuel under any design
D.Has no lubrication requirement of any kind
Explanation: A two-stroke cycle produces a power stroke every crank revolution and commonly uses intake/exhaust ports. It still needs lubrication (often oil mixed with fuel or separate oiling) and can run on petrol; four revolutions per power stroke would describe two complete four-stroke cycles incorrectly.
3The main function of the engine oil pump in a pressure lubrication system is to:
A.Circulate lubricant under pressure to bearings and oil galleries
B.Generate spark at the plug electrodes
C.Meter diesel into the combustion chamber as the injector
D.Cool cabin air through the evaporator only
Explanation: The oil pump drives pressurised oil through galleries to crankshaft/rod bearings and other lubricated points. Spark is ignition; diesel metering is injection; cabin A/C is a separate system.
4A thermostat in a liquid-cooled engine is primarily intended to:
A.Help the engine reach and maintain a suitable operating temperature by controlling coolant flow through the radiator
B.Store fuel for the carburettor float chamber
C.Charge the battery during idle only
D.Measure tyre inflation pressure
Explanation: The thermostat restricts coolant flow to the radiator until the engine warms, then opens to regulate temperature. It is not a fuel tank, charging device, or tyre gauge.
5In multi-cylinder engines, firing order is chosen mainly to:
A.Balance dynamic forces and produce smoother power delivery
B.Eliminate the need for any cooling system
C.Make the clutch unnecessary
D.Replace the differential on rear-drive cars
Explanation: Firing order sequences power strokes so crankshaft loading is smoother and vibration is reduced. Cooling, clutch, and differential remain necessary for their own functions.
6OHV and OHC valve arrangements differ mainly because:
A.OHC places the camshaft in or on the cylinder head, while OHV typically drives valves via pushrods from a lower camshaft
B.OHV engines never have valves at all
C.OHC engines cannot use liquid cooling
D.Both terms only describe diesel injectors
Explanation: Overhead-valve (pushrod) designs usually keep the cam in the block and lift valves through pushrods/rockers; overhead-cam designs locate the camshaft in the head. Both can be cooled and are about valve gear, not injectors.
7Which statement best describes a major difference between SI and CI engines as taught in HSC Automobile Technology?
A.SI engines ignite a premixed charge with a spark; CI engines compress air and inject fuel that auto-ignites
B.CI engines always use spark plugs and petrol only
C.SI engines never use a cooling system
D.CI engines cannot have multi-cylinder layouts
Explanation: Spark-ignition mixes air and fuel (or injects petrol) and uses a spark; compression-ignition compresses air highly and injects diesel that ignites from heat of compression. CI does not rely on spark plugs for normal operation; both engine types can be multi-cylinder and cooled.
8The primary purpose of a radiator pressure cap is to:
A.Raise the coolant boiling point by pressurising the cooling system and allow controlled relief/return of coolant
B.Meter fuel to the injectors
C.Provide the only path for exhaust gases
D.Lubricate the main bearings directly
Explanation: A pressure cap maintains system pressure so coolant boils at a higher temperature and includes relief/return functions with the reservoir as designed. It does not meter fuel, carry exhaust, or lubricate bearings.
9MPFI (multi-point fuel injection) systems are preferred over simple carburettors mainly because they:
A.Meter fuel more accurately to each cylinder, improving efficiency, emissions control, and response
B.Completely remove the need for any air filter
C.Eliminate all electrical sensors from the vehicle
D.Replace the need for engine oil
Explanation: MPFI uses injectors (and sensors/ECU control) to deliver fuel more precisely than a carburettor, aiding economy, drivability, and emissions. Air filtration, sensors, and oil lubrication remain essential.
10In a conventional diesel fuel system, the fuel injection pump (FIP) mainly:
A.Raises fuel pressure and times/meters delivery to the injectors
B.Cools the radiator by circulating water only
C.Charges the battery at high idle
D.Opens the intake valves mechanically
Explanation: The FIP pressurises diesel and delivers timed, metered fuel toward injectors. Cooling pumps move coolant; charging is the alternator; valves are driven by the valve train.
