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, then providing 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
