Worked Solution & Example Answer:6.1 Name THREE engine parts that are indirectly driven by the crankshaft - NSC Mechanical Technology Automotive - Question 6 - 2022 - Paper 1
Step 1
Name THREE engine parts that are indirectly driven by the crankshaft.
Answer
Three engine parts that are indirectly driven by the crankshaft include:
- Camshaft - This component controls the opening and closing of engine valves.
- Water pump - This is responsible for circulating coolant throughout the engine to maintain the optimum operating temperature.
- Alternator - The alternator generates electrical power to charge the battery and power the electrical system of the vehicle.
Step 2
Step 3
State FOUR features, other than vibration dampers, which are built into an engine to improve balance.
Answer
Features that improve engine balance include:
- Counterweights on the crankshaft - These help to counteract the imbalance of the rotating components.
- Careful balancing of flywheels - This helps maintain rotational stability.
- Uniformity in connecting rods and pistons - Keeping these components as light and uniform as possible facilitates balance.
- Equal intervals between power strokes - This ensures that the forces acting on the engine are evenly distributed.
Step 4
State TWO advantages of using V-type engines compared to in-line (straight) engines in motor vehicles.
Answer
Advantages of V-type engines include:
- Compact design - V-type engines can be mounted in smaller engine compartments, allowing for more design flexibility in vehicle engineering.
- Improved power-to-weight ratio - The shorter length of V engines results in a lighter overall engine, enhancing performance.
