SYSTEM / ECM System OUTLINE ECM (Engine Control Module) receives the signals from sensors and MC ECM processes and drives the two-way valve, suction control valve and EGR (Exhaust Gas Recirculation) motor in order to control the supply pump, injector pump and EGR valve. Fuel Injection Control Fuel Injection Amount Correction Preheating Control EGR Control Engine Stop Control The supply pump is driven by the engine and produces high-pressure fuel. The common rail distributes high-pressure fuel produced by the supply pump to the injector in each engine cylinder. The injector injects high-pressure from the com- mon rail.
