This engine uses double solenoid unit injectors. Unlike systems that require separate
components for delivering, pressurizing and injecting, this unit injector combines
these functions. These injectors precisely control the fuel delivery because of the two
solenoids. The solenoids, pump and nozzle are in a single body in close proximity
to each other.

The injector is set in a pressurized fuel gallery where the fuel temperature is constant.
Uniform fuel temperature means uniform quantity in each injection which means
uniform power output from each cylinder.

The fuel pump pressurizes the gallery so that fuel rushes into each injector when it
opens. Gallery pressure is regulated by a valve that delivers excess fuel back to the
tank.

Copper sleeves, acting as coolant jackets, line the bottoms of the injector bores.
Engine coolant circulates around these sleeves aiding the process of controlling
injection temperature.
