Mitsubishi L200 4 car engine management system

Engine management system — design description
The engine management system is designed to perform a number of basic and additional functions. The main functions of the system include injecting the right amount of...

Electronic engine control unit (ECM)
The block issues control signals to actuators based on sensor data. 1. Input signals from sensors; 2. Input signal processing device; 3. Microprocessor (32 bit); 4....

Accelerator pedal position sensors (primary and backup)
They give a signal in the form of a voltage about the position of the accelerator pedal. Duplication is used to eliminate random errors. In this case, the ECM compares...

Pressure sensor in TKVD
Sensor data (voltage) are used to regulate the pressure in the TKVD. The sensor is installed on the TKVD. Sensor characteristic

Temperature sensors
The operation of temperature sensors is based on the use of special temperature-sensitive resistors, in which the dependence of resistance on temperature is close to...

Air flow meter (by weight)
Measures the mass of air passing through it. The data is used to maintain the optimum air-fuel ratio. The sensor is installed in the air filter housing. The measured...

Crankshaft position sensor
This sensor measures the angle of rotation of the crankshaft. At the same time, by correlating the angle of rotation with time, the crankshaft speed is obtained. This...

Camshaft position sensor
Determines the position of the TDC of the compression stroke in the 1st cylinder. The sensor is installed in the cylinder head. The driving element is a rotor with...

EGR valve position sensor
Generates a feedback signal in the exhaust gas recirculation system. The sensor is mounted on the EGR valve housing.

Manifold absolute pressure sensor
The signal from this sensor is used to correct the amount of injected fuel depending on the air pressure in the intake manifold.

Fuel filter pressure sensor (if equipped)
The sensor signal is used to determine the degree of contamination of the fuel filter. The sensor is installed on the fuel filter.

Other sensors and signaling devices
Ignition key (turning on the power of the devices) When the ignition is turned on, a voltage signal is transmitted to the ECM to turn on the control system power relay....

Fuel injectors
Fuel is injected into the engine cylinders in accordance with the signal from the ECM. Each instance of this product is assigned a 30-digit alphanumeric identification...

Fuel supply control valve to injection pump
Regulates the fuel supply to the high pressure fuel pump, and in connection with this, the pressure in the high pressure fuel pump. The opening of the valve is...

Stepper motor of the exhaust gas recirculation valve servo
Controls the EGR valve.

Control relays and indicators
Control power relay Provides power to the motor control circuits. Throttle Servo Motor Controls throttle closing according to ECM signals. Glow plug indicator light...
