Introduction
EMS (Engine Management System)
EMS is a self contained set of components including a custom built computer, sensors,
and actuators which control the operation of an engine by monitoring the engine speed,
load and temperature. While doing that it also provides the ignition spark at the right
time for the prevailing conditions and metering the fuel to the engine in the exact
quantity required.
Typical Components of EMS
1. Electronic Control Unit
2. Multec 3.5 Injectors
3. Throttle Body Assembly (with stepper motor)
4. Engine Coolant Temperature Sensor
5. Intake Air Pressure and Temperature Sensor
6. Oxygen Sensor
7. Ignition Coil
8. Fuel Pump Module
