Which engine is used in heavy duty truck?

The vast majority of heavy-duty trucks are powered by diesel engines.

There are several reasons why diesel engines are the preferred choice for heavy-duty trucks:

  • High power density: Diesel engines can produce a lot of power for their size, which is important for hauling heavy loads.
  • Durability: Diesel engines are known for being very durable and lasting for a long time, even with heavy use.
  • Fuel efficiency (for heavy loads): While not the most fuel-efficient option overall, diesel engines are more efficient than gasoline engines when it comes to hauling heavy loads.

However, the landscape of truck engines is changing. While diesel engines are still dominant, there is a growing market for electric trucks.

Electric trucks are becoming more popular due to concerns about emissions and the potential for lower operating costs. As battery technology continues to improve, electric trucks are expected to become even more common in the future.

In addition to diesel and electric engines, some heavy-duty trucks also use compressed natural gas (CNG) engines.

CNG engines are becoming more popular in some areas due to the lower cost of natural gas compared to diesel. However, CNG engines are not as common as diesel engines, and they have a shorter range than diesel or electric trucks.
