o Monocoque: Body and frame are a single unit
2. Weight:
o Ladder Frame: Heavier
o Monocoque: Lighter
3. Strength:
o Ladder Frame: Better for heavy loads and off-road
o Monocoque: Stronger in crash safety for passengers
4. Cost:

Question 5
(i) A four-stroke internal combustion engine completes one power cycle in four [5]
strokes of the piston:
1. Intake Stroke – The intake valve opens, and the piston moves down,
drawing in the air-fuel mixture.
2. Compression Stroke – The piston moves up with valves closed,
compressing the mixture.

T26 961 – SPECIMEN 3 of 8

3. Power Stroke – A spark ignites the compressed mixture, forcing the piston
downward and producing power.
4. Exhaust Stroke – The exhaust valve opens, and the piston moves up again,
pushing out burnt gases.

(ii) The crankshaft converts the up-and-down (reciprocating) motion of the pistons [5]
into rotational motion that drives the vehicle’s wheels. It is connected to the
pistons through connecting rods and plays a key role in maintaining engine
balance, timing, and delivering power to the drivetrain.

(iii) A fuel injector is an electronically controlled device that sprays a fine mist of fuel [5]
into the engine’s combustion chamber. It receives signals from the engine control
unit (ECU), which determines the exact timing and amount of fuel needed. The
injector opens and closes rapidly, ensuring precise fuel delivery, better
combustion, improved fuel efficiency, and reduced emissions in modern engine.

Question 6
(i) Five Differences Between Diesel Engine and Gasoline Engine: [5]
1. Fuel Type:
o Diesel Engine: Uses diesel fuel
o Gasoline Engine: Uses petrol/gasoline
2. Ignition Method:
o Diesel Engine: Uses compression ignition
o Gasoline Engine: Uses spark ignition
3. Efficiency:
o Diesel Engine: More fuel-efficient
o Gasoline Engine: Less fuel-efficient
4. Power Output:
o Diesel Engine: Higher torque, lower RPM
o Gasoline Engine: Higher speed, lower torque
5. Maintenance Cost:
o Diesel Engine: Generally higher maintenance cost
o Gasoline Engine: Lower maintenance cost

(ii) Five Primary Functions of a Lubrication System in a Vehicle: [5]
1. Reduces Friction – Minimizes wear between moving engine parts.
2. Cools Engine Parts – Helps carry away heat from engine components.
3. Cleans Engine – Removes dirt, metal particles, and sludge through oil
circulation.

T26 961 – SPECIMEN 4 of 8

4. Prevents Corrosion – Forms a protective film on metal surfaces to stop rust.
5. Seals Gaps – Helps seal tiny gaps between piston rings and cylinder walls
for better compression.

(iii) Five Components of a Typical Lubrication System in an Internal Combustion [5]
Engine:
1. Oil Pump – Circulates oil under pressure to engine parts.
2. Oil Filter – Removes impurities and debris from the oil.
3. Oil Pan (Sump) – Stores the engine oil at the bottom of the engine.
4. Pressure Relief Valve – Regulates oil pressure to prevent damage.
5. Oil Galleries (Passages) – Channels through which oil flows to lubricate
engine parts.

Question 7
(i) The oil filter plays a crucial role in maintaining engine health by removing dirt, [5]
metal particles, carbon deposits, and other impurities from the engine oil. Clean
oil ensures smooth engine operation and reduces wear.
How it works:
As oil circulates through the engine, it passes through the oil filter. Inside, a
filtering element traps contaminants while allowing clean oil to flow through.
This filtered oil is then sent back to lubricate engine components, ensuring
efficient and long-lasting engine performance.

(ii) Five Differences Between Wet Sump and Dry Sump Lubrication Systems: [5]
1. Oil Storage
o Wet Sump: Oil is stored in the oil pan (sump) below the engine.
o Dry Sump: Oil is stored in a separate external reservoir.
2. Oil Pump Setup
o Wet Sump: Uses a single oil pump.
o Dry Sump: Uses multiple pumps (scavenge and pressure pump).
3. Engine Height
o Wet Sump: Increases engine height due to the sump.
o Dry Sump: Allows a lower engine profile, suitable for performance
vehicles.

T26 961 – SPECIMEN 5 of 8

4. Lubrication Efficiency
o Wet Sump: Less efficient under high-speed or inclined conditions.
o Dry Sump: Maintains consistent oil flow even during aggressive
driving or racing.
5. Cost and Complexity
o Wet Sump: Simpler and cheaper.
o Dry Sump: More complex and expensive to maintain.

(iii) Importance of Oil Viscosity in the Lubrication System: [5]
Oil viscosity refers to the thickness or resistance to flow of the oil. It plays a crucial
role in the effectiveness of the lubrication system:
1. Proper Film Formation – Correct viscosity ensures a stable oil film
between moving parts, reducing friction and wear.
2. Cold Start Protection – Low-viscosity oil flows quickly during cold starts,
providing immediate lubrication.
3. Heat Resistance – High-viscosity oil maintains its protective qualities at
high temperatures without breaking down.
4. Engine Efficiency – The right viscosity reduces energy loss from internal
resistance, improving fuel efficiency.
5. Component Protection – Ensures engine parts like bearings, pistons, and
crankshaft remain well-lubricated under varying conditions, extending
engine life.

Question 8
(i) Five Functions of a Vehicle's Cooling System: [5]
1. Maintains Optimal Engine Temperature – Prevents the engine from
overheating by regulating temperature.
2. Removes Excess Heat – Transfers heat away from engine components to
the atmosphere.
3. Prevents Engine Damage – Avoids warping, cracking, or seizing of parts
due to excessive heat.
4. Improves Engine Efficiency – Keeps engine parts at ideal operating
temperature for better performance and fuel efficiency.
5. Maintains Lubrication – Prevents oil from breaking down due to high
temperatures, ensuring proper lubrication.

(ii) Components of a Typical Liquid Cooling System in an Internal Combustion [5]
Engine:
1. Radiator – Cools the hot coolant by transferring heat to the air.
2. Water Pump – Circulates coolant throughout the engine and cooling
system.

T26 961 – SPECIMEN 6 of 8

3. Thermostat – Regulates coolant flow based on engine temperature.
4. Coolant (Antifreeze) – A liquid mixture that absorbs and transfers heat from
the engine.
5. Radiator Fan – Assists in cooling the radiator, especially when the vehicle
is stationary or moving slowly.

(iii) Role and Operation of the Thermostat in a Vehicle's Cooling System : [5]
The thermostat regulates the flow of coolant between the engine and the radiator
to maintain the engine’s optimal operating temperature.
How it operates:
• When the engine is cold, the thermostat stays closed, allowing the engine to
warm up quickly by restricting coolant flow.
• Once the engine reaches a specific temperature (usually around 80–90°C),
the thermostat opens, allowing coolant to flow to the radiator for heat
dissipation.
This helps in improving fuel efficiency, reducing engine wear, and
preventing overheating.
Question 9
(i) Five Primary Functions of a Vehicle's Transmission System: [5]
1. Transfers Power – Transmits engine power to the wheels.
2. Speed and Torque Control – Adjusts speed and torque as needed through
gear changes.
3. Allows Vehicle to Move in Reverse – Enables backward motion using
reverse gear.
4. Disconnects Engine from Wheels – Allows the engine to run without
moving the vehicle (via neutral or clutch).
5. Improves Fuel Efficiency – Maintains optimal engine speed for different
driving conditions.

(ii) Five Primary Functions of a Vehicle's Steering System : [5]
1. Controls Direction – Allows the driver to guide and change the direction of
the vehicle.
2. Provides Stability – Maintains vehicle balance and control while turning.
3. Ensures Cornering Safety – Enables smooth and safe turns at various
speeds.
4. Reduces Driver Effort – Power-assisted systems make steering easier and
more comfortable.
5. Absorbs Road Shocks – Works with suspension to reduce the impact of
road irregularities on steering.

Perform basic underbody inspections or repairs
(d) Combination Pliers (also known as Linesman Pliers) : Combination pliers
are multi-purpose hand tools used by mechanics and electricians for gripping
and holding objects, cutting wires etc.
