Anh Tuan, owner of a Hyundai HD120 truck used for transporting construction materials on the Lang – Hoa Lac route, shared: “When I first started using trucks, I always struggled with the carburetor, constantly worried about engine stalls and high fuel consumption. Since switching to a newer truck with an electronic fuel injection system, everything has become much easier. The truck runs smoothly, accelerates better, and saves fuel.”

What is an Electronic Fuel Injection System?

No longer unfamiliar to car users, electronic fuel injection (EFI) systems are becoming increasingly popular in trucks in Vietnam. So, what makes this system so special?

Simply put, an electronic fuel injection system acts like a smart “chef,” responsible for mixing fuel and air in the optimal ratio before delivering it to the combustion chamber. Thanks to the precise control of the Engine Control Unit (ECU), the EFI system offers several advantages over traditional carburetors:

Fuel Efficiency: The amount of fuel injected into the combustion chamber is precisely controlled, resulting in more efficient operation and better fuel economy.
Increased Engine Performance: Optimal fuel delivery leads to a more powerful engine, faster acceleration, and reduced harmful emissions.
Easy Starting: The EFI system eliminates the problem of hard starting in cold weather, making it easier than ever to start your vehicle.
