Dual Injection engine: DI + MPI – how it works?
More and more new emission standards force engineers to constantly change the design of petrol engines. An increasingly popular trend is mixed injection engines. So in one engine we have two injection systems at the same time – multi-point indirect injection (MPI – Multipoint Injection) and direct injection into the combustion chambers (DI – Direct Injection). This means that there are two petrol injectors per cylinder, operating separately, which dose petrol in front of the valves and directly into the combustion chamber. Auto, depending on the load, uses either 1 type of injection or 2 types simultaneously.
