What do you mean by a single point and more points for a Jinbei car?

When the gasoline engine evolved into the era of electronic control injection, it was generally single-point injection, that is, the injector was on the throttle body or intake manifold. However, because the length and bending angle of the intake manifold cannot be the same, in other words, the stroke of mixed steam from the throttle to the intake valve is different, and the mixed concentration is different, which is easy to cause the disadvantages of cylinder deviation and severe vibration.

Later, multi-point injection came out, but the difference was that the number of injectors changed from one to many, which were installed near the intake valve (intake manifold) or directly in the combustion chamber (direct injection in the cylinder), thus avoiding the shortcomings of single-point injection and accurately controlling the fuel injection quantity of each cylinder according to the working conditions.
