Abstract

The Common Rail fuel injection system is a system with many advantages: the fuel is injected at a very high pressure, possibly over 2500 (bar); injection pressure and time are independent of engine speed; allows multi-stage injection to limit the pressure increase in the cylinder. The engine ECU receives signals from the sensors and calculates the timing and flow to control the pressure and injection volume in accordance with the engine’s condition, thereby increasing the engine’s efficiency and reducing fuel consumption. The CR control fuel injection system consists of the engine ECU, high pressure pump, distribution pipe, injectors and various sensors. From the results obtained from experiment and research, the author builds a control model of Common Rail fuel system on CRDI D4CB engine of KIA FRONTIER.
