The difference between EFI and Denso EFI

Both EFI and EFI refer to the fuel injection system of internal combustion engine, but there are some differences between them.

1. Principle: EFI refers to the precise control of the injector by the electronic control unit (ECU) to achieve more accurate fuel injection. On the other hand, on the basis of EFI, Denso EFI adds Denso throttle. The electronic throttle can change the pressure in the intake manifold according to the requirements of different working conditions, so as to realize more accurate fuel injection and intake adjustment.

2. Effect: Compared with the traditional mechanical fuel injection system, EFI can provide more accurate fuel injection and better combustion effect, thus improving power and fuel economy. On this basis, through the control of electronic throttle, the intake air can be controlled more accurately, and the combustion efficiency and fuel economy can be improved.

3. Maintenance: Because EFI and EFI systems involve complex components such as electronic control unit (ECU) and electronic throttle, their maintenance and repair are more complicated than traditional mechanical fuel injection systems. Professional technicians are needed for maintenance and troubleshooting.

In a word, both EFI and EFI are advanced fuel injection systems, which are more accurate and efficient than traditional mechanical fuel injection systems. However, on this basis, the electronic throttle valve is added, which further improves the combustion efficiency and fuel economy.
