For context, here are some common engine sizes found in trucks and buses:
1. Small Trucks and Buses:
- 4-6 liters (diesel)
- 5-8 liters (gasoline)
2. Medium-Duty Trucks and Buses:
- 7-10 liters (diesel)
- 9-13 liters (gasoline)
3. Heavy-Duty Trucks and Buses:
- 11-15 liters (diesel)
- 14-18 liters (gasoline)
4. Semi-Trucks and Long-Haul Buses:
- 16-24 liters (diesel)
- 19-26 liters (gasoline)
5. Specialized Vehicles:
- Some specialized trucks and buses may have even larger engines, exceeding 26 liters in displacement.
It's worth noting that diesel engines are more common in trucks and buses due to their higher torque output and fuel efficiency compared to gasoline engines. However, there are still some trucks and buses that use gasoline engines, particularly in regions where gasoline is more affordable.
