What does MPI on a car engine mean?
1 Answers
MPI on a car engine stands for Multi-Point Injection, also known as multi-valve injection, sequential fuel injection, or individual fuel injection. It involves injecting gasoline at the rear end of the intake manifold of each cylinder, in front of the intake valve, before the valve opens, to form a combustible mixture that then enters the cylinder for combustion. The characteristics of multi-point fuel injection are: 1. Avoiding uneven air distribution and power loss caused by overlapping intake of adjacent cylinders; 2. Precise control of fuel injection quantity and timing based on timing. The forms of multi-point fuel injection include: simultaneous injection, group injection, and sequential injection.
