5. FUEL SYSTEM

[1] OVERVIEW

The fuel system of this engine is completely different from previous jerk fuel injection pumps. Our common rail
system not only complies with strict emission regulations, it enables multiple, precise high-pressure injections that do
not vary with engine RPM.
The system is an electronically controlled fuel injection device, with a supply pump (3) that pressurizes the fuel,
a rail (2) that stores the high-pressure fuel, injectors (1) that inject the fuel under high-pressure via solenoids into each
cylinder and an engine ECU that controls them all.
Various parameters are controlled by the engine ECU, such as the amount of fuel from the injectors and their
timing, the pressure of fuel in the rail, etc., as sensed via signals from each sensor and CAN communications from
the engine's ECU.
This results in fuel always being injected under ideal conditions, which suppresses the hallmark of a diesel engine,
the black smoke during takeoff and acceleration, so there is less smoke, it is cleaner and with a higher output of
power.
