1How many revolutions of the crankshaft are required for a four-stroke motorcycle engine to complete one full operating cycle (intake, compression, power, exhaust)?

A.One revolution

B.Two revolutions

C.Three revolutions

D.Four revolutions

Explanation: A four-stroke engine completes its cycle in four piston strokes, and since two strokes occur per crankshaft revolution, the full intake-compression-power-exhaust cycle takes exactly two crankshaft revolutions.

2In which stroke of a four-stroke engine does the actual combustion of the air-fuel mixture drive the piston downward?

A.Intake stroke

B.Compression stroke

C.Power stroke

D.Exhaust stroke

Explanation: During the power (combustion) stroke, the ignited air-fuel mixture expands rapidly, forcing the piston down and producing the engine's useful work that turns the crankshaft.

3A two-stroke motorcycle engine produces a power stroke once every how many crankshaft revolutions?

A.Every revolution

B.Every two revolutions

C.Every three revolutions

D.Every four revolutions

Explanation: A two-stroke engine fires on every crankshaft revolution because it completes intake, compression, power and exhaust functions within two strokes (one revolution), giving more power strokes per minute than a four-stroke of similar size.

4Why do most two-stroke motorcycle engines require oil to be mixed with the petrol or injected into the intake?

A.To increase the octane rating of the fuel

B.To lubricate the crankshaft, bearings and cylinder since there is no separate oil sump circulation

C.To cool the exhaust gases

D.To raise the fuel's flash point

Explanation: A typical two-stroke uses crankcase induction and has no pressurised sump, so lubricating oil is carried with the fuel charge (premix or oil-injection) to lubricate the bearings, crank and cylinder walls as the mixture passes through.

5What is the main advantage of a multi-cylinder engine over a single-cylinder engine of the same total displacement on a motorcycle?

A.It always uses less fuel

B.It generally runs smoother with less vibration and can rev higher

C.It needs no cooling system

D.It eliminates the need for a gearbox

Explanation: Multi-cylinder engines distribute power pulses across more, smaller cylinders, which reduces vibration, allows higher engine speeds and produces smoother power delivery than a single large cylinder.

6In a carburettor, what is the primary function of the venturi (the narrowed throat)?

A.To store excess fuel

B.To speed up the airflow and lower its pressure so fuel is drawn from the jet

C.To filter incoming air

D.To cool the air-fuel mixture

Explanation: The venturi narrows the air passage, accelerating the air and lowering its static pressure; this pressure drop draws fuel out of the main jet, atomising it into the airstream to form the combustible mixture.

7What component in a carburettor float bowl maintains the correct fuel level by opening and closing fuel inlet flow?

A.Main jet

B.Float and needle valve

C.Throttle slide

D.Choke plate

Explanation: The float rises and falls with fuel level and operates the needle valve, closing the inlet when the level is correct and opening it as fuel is consumed, keeping the bowl at a steady level for consistent metering.

8Which carburettor circuit primarily supplies fuel at idle and small throttle openings?

A.Main jet

B.Pilot (slow) jet

C.Accelerator pump

D.Float chamber vent

Explanation: The pilot (or slow) jet meters fuel for idle and low throttle openings; the main jet takes over progressively as the throttle opens toward wide-open.

9What is the purpose of the choke (or enrichener) on a motorcycle carburettor?

A.To lean the mixture for high-speed running

B.To enrich the air-fuel mixture for easier cold starting

C.To increase the idle air supply

D.To shut off the fuel when parking

Explanation: The choke temporarily enriches the mixture (more fuel relative to air) so a cold engine, which needs extra fuel because some condenses on cold surfaces, will start and run until it warms up.

10Compared with a carburettor, a key advantage of electronic fuel injection (EFI) on modern motorcycles is that it:

A.Requires no electrical power

B.Precisely meters fuel using sensors for better efficiency and emissions

C.Cannot be used with a catalytic converter

D.Eliminates the need for an air filter

Explanation: EFI uses sensors (throttle position, air and engine temperature, oxygen, etc.) and an ECU to deliver a precise fuel quantity for the operating condition, improving fuel economy, cold starting, drivability and emissions control.

About the BTEB Motorcycle Servicing Exam

The BTEB National Skill Certificate in Motorcycle Servicing certifies competence in servicing and repairing motorcycles in Bangladesh. The trade-theory component covers two-stroke and four-stroke engines, fuel and ignition systems, lubrication and cooling, transmission and braking, suspension, electrical systems, wheels and tyres, periodic maintenance and workshop safety, alongside a hands-on practical assessment.

Assessment

Competency-based assessment combining a theory paper (multiple-choice and short written questions) with a separate supervised practical test, administered by BTEB through affiliated technical institutes. Question counts vary by level (Basic/NSC).

Time Limit

Theory papers typically run a few hours, with the practical competency test conducted separately under supervision. Confirm exact timing with your institute.

Passing Score

BTEB sets the competency standard, generally requiring a pass in both theory and practical components; written-paper thresholds of around 40-50% are commonly reported, but the definitive standard depends on your level and institute.

Exam Fee

Registration and assessment fees are set by BTEB and the enrolling institute and are government-subsidised but change periodically. Confirm the current amount with your institute. (Bangladesh Technical Education Board (BTEB))

BTEB Motorcycle Servicing Study Tips from Top Performers

1Master the difference between two-stroke and four-stroke operation first, then build up through fuel, ignition, lubrication and cooling, because later topics assume you understand the basic engine cycle.

2Pair each theory topic with hands-on practice in the workshop, such as setting a spark-plug gap, checking chain slack or measuring battery specific gravity, since BTEB assesses practical competence alongside theory.

3Always observe workshop safety and use the correct tool for each job, for example a feeler gauge for gaps, a hydrometer for battery electrolyte and a torque wrench for fasteners, as safe and correct tool use is tested and expected on the job.
