* Variety of Engines: 18-wheelers, or semi-trucks, come with a wide range of engine sizes and types. This depends on the truck's intended use, weight capacity, and desired fuel efficiency.
* Common Types:
* Diesel Engines: These are the most common type for long-haul trucking due to their high torque and fuel efficiency.
* Gasoline Engines: Less common but still used for some applications, especially lighter-duty trucks.
* Engine Displacement: This is measured in liters (L) and indicates the volume of the engine cylinders. Typical displacement ranges for semi-trucks are:
* Small: 10-13L
* Medium: 13-15L
* Large: 15L and above
Here's what's important to know:
* Horsepower: This is a measure of the engine's power output and is often more relevant than displacement.
* Torque: This is the twisting force that an engine produces, crucial for moving heavy loads.
* Fuel Efficiency: This is a key consideration for long-haul trucking and influences engine choice.
If you have a specific truck model in mind, you can find detailed engine specifications from the manufacturer's website.
