EMS(Engine Management System)
2. THE COMPONENT PARTS OF THE EMS
EMS CONSISTS OF INTAKE AND FULE, IGNITION AND CONTROL SYSTEM.
1) INTAKE SYSTEM
As a system which controls and measures air to be necessary for combustion in engine, the intake system
is composed of pressure sensor of intake parts, intake on sensor, throttle position sensor, throttle body, air
cleaner and ISA(Idle Speed Actuator), etc.
In idling, because throttle value is almost closed, the idle status of engine shall be controlled by means
that idle speed control system is installed in order to control small of quantity of air being necessary for
combustion.
2) FUEL SYSTEM
As a system to supply required fuel for consumption in engine combustion chamber from fuel tank to
injector, this Fuel system is composed of fuel tank, fuel pump, fuel filter, fuel pressure regulator, division
pipe and injector.
The fuel in tank, being high pressed by fuel pump, moves to the division pipe through fuel filter.
Next the fuel is supplied to injector being highly maintained as regulated pressure about the pressure of
intake system.
Injector sprays fuel into the intake system by injection signals of ECU.
3) IGNITION SYSTEM
The ignition system is composed of spark plug which makes ignition spark, a spark timing control part to
control proper spark time in cylinder, high-voltage system, and so forth.
4) CONTROL SYSTEM
①
Various sensors to move electric signals converted by checking the current engine status
②
Input interface which works various processes like regulating voltage levels, removal of noise, A/D
conversion, amplifying of inputted signals from above sensors.
③
Micro-computer which decides output value through various calculating, arithmetic and logic
processing.
④
Output interface to amplify the above output signals.
⑤
Actuator being mechanically worked by receiving the amplified output signals.
