机械-About the machinery

 A  truck engine  is usually a heavy-duty diesel engine. The choice of this type of engine is not random but based on careful consideration of the specific needs and challenges trucks face on the road. The dominance of the heavy-duty diesel engine Why Diesel? The use of heavy-duty  diesel engines in trucks  is based primarily on their high efficiency and torque characteristics. Diesel engines are known for producing high torque at low rpm, ideal for the large loads and frequent starts and stops required in long-haul transportation. ● Fuel Efficiency Diesel engines are more fuel-efficient than gasoline engines. The energy density of diesel fuel allows trucks to travel longer distances, reducing the number of refueling trips and improving the overall efficiency of long-haul transportation. ● Performance Factors Torque and Power Heavy-duty diesel engines provide the ample torque and power needed to move large loads. This is critical for trucks, especially when climbing hills, pulling heav

What is the difference between a Semi-Trailer and a Tractor-Trailer? It's a common question, but the answer could be more satisfying. Before answering this question, let's look at how these two types of trucks are defined and the substantial differences between them. Defining Semi-Trailer and Tractor-Trailer First, let's briefly define semi-trailers and tractor-trailers. A Semi-Trailer is a truck whose trailer is partially attached to the rear of a tractor-trailer, not directly, but through a hitch. Conversely, a tractor-trailer is a type of truck in which the trailer portion is attached directly to the rear of the tractor, forming a complete single vehicle. The Structural Difference The most obvious difference between a semi-trailer and a tractor-trailer is their structure. The trailer section of the semi-trailer is only connected to the rear of the tractor rather than via a full connecting bridge. This design allows the semi-trailer to be more flexible and steer around c
