Engine mass affects vehicle performance, fuel efficiency, and handling.

• A heavier engine can negatively impact fuel efficiency as it requires more energy to move the vehicle.

• A lighter engine can improve handling and acceleration.

• Engine mass also affects weight distribution, which can impact stability and traction.

• Engine mass is particularly important in sports cars and racing vehicles where weight and performance are cr

The material used for piston is typically aluminum alloy or cast iron.

• Aluminum alloy is lightweight and has good thermal conductivity, making it suitable for high-performance engines.

• Cast iron is heavier but more durable and can withstand high temperatures and pressures.

• Other materials like steel, titanium, and ceramic are also used in specialized applications.

• The choice of material depends on factors like engine type,
