JENGINE CONTROL SYSTEM 1. General
The engine control system of the 1KD-FTV and 2KD-FTV engines has the following system.
System Fuel Injection Volume Control (See page EG-156) Fuel Injection Timing Control (See page EG-157) During Starting Control (See page EG-158) Idle Speed Control (See page EG-159) Fuel Pressure Control (See page EG-160) Pilot Injection Control (See page EG-163) Glow Plug Control Intake Shutter Control (See page EG-164) Swirl Control (See page EG-164) Turbocharger Control (See page EG-165) EGR Control (See page EG-169) Air Conditioner Cut-Off Control*1 Engine Immobilizer*2 Diagnosis (See page EG-171) Fail-Safe (See page EG-171) Outline Based on the signals received from the sensors, the engine ECU determines the fuel injection volume in accordance with the engine condition. Based on the signals received from the sensors, the engine ECU determines the fuel injection timing in accordance with the engine condition. To facilitate startability, the engine ECU optimally controls the injection volume and injection timing during starting. The engine ECU determines the idle speed in accordance with the engine condition, and controls the fuel injection volume in order to maintain the target idle speed. Based on the signals received from the sensors, the engine ECU determines the fuel pressure via SCV (Suction Control Valve) in accordance with the engine condition. Based on the signals received from the sensors, the engine ECU determines pilot injection volume/timing, and interval (between pilot injection and main injection) in accordance with the engine condition. Controls the length of time when the current is applied to the glow plugs, in accordance with the coolant temperature. D Controls the intake shutter valve (throttle valve) opening angle in accordance with the engine condition. D Fully close the intake shutter valve (throttle valve) in order to reduce the vibration when the engine is stopped. Based on
