4.13. Complex Control System of the Engine (CCSE)



Cars with GA14DE, GA16DE and SR20DE engines are equipped with the complex control system of the engine (CCSE) of the Nissan ECCS. KSUD is intended for management of injection of fuel and the ignition advancing corner (IAC). It consists of two subsystems: managements of injection of fuel and management of UOZ. Both systems are interconnected and work synchronously. Synchronization of work of a subsystem and the main operation of the engine is carried out by the controller on signals of sensors. The controller, uniform for both subsystems, on the basis of information obtained from sensors according to the program put in memory operates actuation mechanisms. At the same time UOZ, quantity and the moment of supply of fuel depending on power setting is automatically optimized. At violation of operation of some sensors the controller passes to the reserve program of management. It allows to continue the movement on the car in case of malfunction.
