WAEC GCE Auto Mechanics 2025 Practice Theory Questions (Sample)

Question 1: Explain the difference between a two-stroke engine and a four-stroke engine.

Answer:

  • A two-stroke engine completes a power cycle in two strokes of the piston (one revolution of the crankshaft). It is lighter, produces more power for its size, but consumes more fuel.

  • A four-stroke engine completes a power cycle in four strokes (two revolutions of the crankshaft). It is more fuel-efficient, durable, and widely used in cars.

Question 2: List and explain three causes of engine overheating.

Answer:

  1. Low coolant level: Insufficient water or coolant in the radiator can cause overheating.

  2. Faulty thermostat: A thermostat stuck in the closed position prevents coolant circulation.

  3. Damaged water pump: When the pump fails, coolant does not flow properly, leading to overheating.

Question 3: What are the functions of engine oil in an automobile?

Answer:

  1. Lubricates engine parts to reduce friction.

  2. Cools engine components by carrying away heat.

  3. Cleans the engine by removing dirt and deposits.

  4. Seals gaps between piston rings and cylinder walls.
