Many of fuel system of the engine are electrically controlled. Multi Point Injection (MPI) system is that injectors are installed in each cylinder. Power offers two kinds of a injector, gtop feed h and gside feed (bottom feed) h.
The number of injector nozzles is divided into one and two by the specification of the engine. DOHC 4 valve engine has two intake ports and often takes two injector nozzles. The reason is to avoid incomplete combustion caused by fuel mist hit and crushed on the wall of a intake port and flowing in drops. The injector basically sprays fuel (150-200 microns) on the back of a valve head preventing fuel mist from hitting against the wall of a intake port
The injector capacity becomes larger and larger, the bad influence of this problem is increased.
PWR big capacity injectors realize not only high power output but also improvement of the response and cleaning exhaust gas. |
