Electronic Fuel Injection System (EFI) and Advanced Engine Management System (EMS)

Technology Outline

The Engine Management System (EMS) is responsible for controlling the amount of fuel being injected and for adjusting the ignition timing. Optimum functioning of the EMS assures maximum engine power, with the lowest amount of exhaust emissions and the lowest fuel consumption. The Omnitek EMS offers self diagnostic capabilities (OBD) and CAN communication.

The EMS is comprised of sensors for intake air and coolant temperature, intake manifold absolute pressure (MAP) and throttle position (TPS), as well as sensors for engine speed and signals for the required injection and ignition spark events, and a sensor for information about the oxygen content in the exhaust (4-Wire Oxygen Sensor or Wideband UEGO Sensor). Furthermore, there is an idle speed motor for adjusting and stabilizing the idle speed, or an electronic throttle body and finally a fuel pressure regulator and fuel injector(s). The supplied high-energy ignition coils are controlled by the integrated ignition module. For alternative fuel applications fuel rail pressure and temperature sensors are also utilized.

The ECU calculates the correct amount of fuel and ignition timing by "reading" the information supplied by various sensors and compares these values with the appropriate points in fuel and ignition-map of the ECU.

The Omnitek EMS is easy to calibrate, which guaranties a reduced time to go from prototype to production. Engine manufacturers can even perform most of the system integration in their own laboratory.
