Chapter 1 Describes the SIMK-31 engine management system
一、
Overview
The engine management system mainly consists of sensors, microprocessors (ECU), executive
device is composed of three parts, the inhalation of air traffic control, fuel injection and ignition
advance angle of the engine work.
In the engine electronic control system, sensor as input part, for a variety of physical
measurements (temperature, pressure), and turn it into a corresponding electrical signal; the role
of ECU is to accept input signal sensor, processing and calculation according to the program, to
generate a control signal output corresponding to the power drive circuit, power driving circuit is
driven by the actuator perform different actions, make the engine run in accordance with the
established control strategy; at the same time, fault diagnosis system of ECU for each component
or control functions of the system for monitoring, once detected faults and confirmation, the
memory fault code, call "limp home" function, when the detected fault is eliminate, then normal
recovery using.
二、
The basic components of electronic control system
The electronic controller (ECU) Injector Crank position sensor
Oil rail Camshaft position sensor Carbon canister control valve
Intake manifold Oxygen sensor Temperature sensor
Three way catalytic converter Inlet pressure / temperature sensor
Ignition coil and the high-voltage wire
Idle speed regulator Oil pump assembly Solar term door position sensor
Solar term door assembly Knock sensor Temperature sensor
