An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.
The Ford EEC (Electronic Engine Control) system, which utilized the Toshiba TLCS-12 microprocessor, went into mass production in 1975. [ 7 ] The first Bosch engine management system was the Motronic 1.0 , which was introduced in the 1979 BMW 7 Series (E23) [ 8 ] This system was based on the existing Bosch Jetronic fuel injection system, to ...
Aero Engine Controls is the former name of Rolls-Royce Controls and Data Services.The company produces engine control software, electronic engine controls (EEC), fuel metering units (FMU), fuel pumps and engine actuators for a large number of common commercial and military aircraft. [1]
Actuators or solenoids which convert the control unit's electrical output signal into mechanical control movement. ECM (Electronic Control Module ) or Engine ECU (Electronic Control Unit) with microprocessors which process information from various sensors in accordance with programmed software, and outputs the required electrical signals into ...
The traction control system (TCS) intervenes; the knock control system intervenes; The ECM regulates the throttle area (opening angle) together with the turbo wastegate so that the correct torque is attained, i.e. air mass per combustion. Fuel injection is sequential and regulated with air mass per combustion and engine speed as parameters.
The system was an evident improvement over mechanical control but had its drawbacks, including common electronic noise interference and reliability issues. Full authority analogue control was used in the 1960s and introduced as a component of the Rolls-Royce/Snecma Olympus 593 engine of the supersonic transport aircraft Concorde . [ 3 ]
The Ford EEC or Electronic Engine Control is a series of ECU (or Engine Control Unit) that was designed and built by Ford Motor Company. The first system, EEC I, used processors and components developed by Toshiba in 1973. It began production in 1974, and went into mass production in 1975. It subsequently went through several model iterations.
In engines with fuel injection system, the lever is typically referred to as power lever and controls the amount of fuel that is injected into the cylinders. Propeller control or Governor - Adjusts the propeller blade pitch and regulates the engine load as necessary to maintain the set revolutions per minute (RPM). See the section on propeller ...
