The Omnitek Engine Management System (EMS) is responsible for controlling the correct amount of fuel injected and for adjusting the ignition timing. The spark plug’s main task is to generate the spark to ignite the compressed air-fuel mixture inside the combustion chamber. There are about 20 to 30 actuators in all. The spark-ignition engine requires some device to ignite the compressed air-fuel mixture. Electronic control allows fuel to be burnt efficiently. The reference point is determined by a missing element in the pulse wheel. This saves on the cost of electronics as well as mechanical/physical parts like interconnects across ECUs etc. In 1971, Fairchild Semiconductor and RCA Laboratories proposed the use of MOS large-scale integration (LSI) chips for a wide range of automotive electronic applications, including a transmission control unit (TCU), adaptive cruise control (ACC), alternators, automatic headlight dimmers, electric fuel pumps, electronic fuel-injection, electronic ignition control, electronic tachometers, sequential turn signals, speed indicators, tire-pressure monitors, voltage regulators, windshield wiper control, Electronic Skid Prevention (ESP), and heating, ventilation, and air conditioning (HAVC). All these sensor signals are sent to the ECU, which has the logic circuits to do the actual controlling. The ignition takes place inside the cylinder at the end of the compression stroke, the ignition system serves this purpose. Modern ECUs use a microprocessor which can process the inputs from the engine sensors in real-time. The signal of the throttle position sensor is used to enhance the filling prediction.
