Power Enterprise Injectors

Many of fuel system of the engine are electrically controlled. Multi Point Injection (MPI) system is that injectors are installed in each cylinder.

Power Enterprise(PWR) 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. PWR designed and developed injectors for RB26 (normal one has one intake port.), 1JZ and 2JZ. Big capacity injectors realize not only high power output but also improvement of the response and cleaning exhaust gas.

For Power Enterprise 850cc and above injectors which are also a direct drop in replacement, Although for injector sizes this big, a standalone fuel management system is needed. A piggy back system like the E-Manage or Super AFC will not work. This injector size supports 500+rwhp applications.
