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 (ECU)
The unit 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 secondary)
They give a signal in the form of voltage about the position of the accelerator pedal. Duplication is used to eliminate random errors. In this case, the ECU compares the...

Pressure sensor in the high pressure fuel system
The sensor data (voltage) is used to regulate the pressure in the HPTC. The sensor is installed on the high pressure fuel tank. Sensor characteristics

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

Air flow meter (by mass)
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 crankshaft rotation angle. At the same time, by relating the rotation angle to time, the crankshaft rotation speed is obtained. This data is...

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

EGR valve position sensor
Generates a feedback signal in the EGR system. The sensor is installed on the EGR valve body.

Manifold Absolute Pressure Sensor
The signal from this sensor is used to adjust the amount of fuel injected depending on the air pressure in the intake manifold.

Fuel filter pressure sensor (if the vehicle is equipped with one)
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 alarms
Ignition switch (switching on the power supply of the devices) When the ignition is turned on, a voltage signal is transmitted to the ECU to turn on the control system...

Fuel injectors
Inject fuel into the engine cylinders in accordance with the signal coming from the ECU. Each unit of this product is assigned a 30-digit alphanumeric identification...

Fuel supply control valve to the high-pressure fuel 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 valve opening is proportional to...

Stepper motor for servo drive of EGR valve
Controls the EGR valve.

Control relays and indicators
Control system power supply relay Provides power to the engine control circuits. Electric motor of throttle servo Controls the closing of the throttle valve based on ECM...
