Product Description
Many of fuel system of the engine are electrically
controlled. Multi Point Injection (MPI) system is that injectors are
installed in each cylinder. We offer two kinds of a injector, “top feed”
and “side feed (bottom feed)” (cf. fig. 1). 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 (cf.
fig. 2). The injector capacity becomes larger and larger, the bad
influence of this problem is increased. We designed and developed
injectors for RB26 (normal one has one intake port.), 1JZ and 2JZ. PWR big
capacity injectors realize not only high power output but also improvement
of the response and cleaning exhaust gas.
