Delco ECU used in General Motors vehicles built in 1996. An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine. Systems commonly controlled by an ECU include the fuel injection and ignition systems.
By 2008, Detroit Diesel had produced one million Series 60 engines. [7] In 2007 - 2010 (2008 -2011 trucks), the Detroit Diesel 14L engine was modified to meet new emissions standards and went to a dual ECM configuration (DDEC VI). This engine ran higher compression, higher injector pressure and a DPF exhaust filter. The block and crank remained ...
A full authority digital engine (or electronics) control (FADEC) is a system consisting of a digital computer, called an "electronic engine controller" (EEC) or "engine control unit" (ECU), and its related accessories that control all aspects of aircraft engine performance.
The development of an ECU involves both hardware and software required to perform the functions expected from that particular module. Automotive ECU's are being developed following the V-model. [1] Recently the trend is to dedicate a significant amount of time and effort to develop safe modules by following standards like ISO 26262. [5]
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.
The ECU is sealed and cannot be serviced, and the EPROM cannot be re-programmed. Later, the name was synonymous with a form of fuel injection. In such an application, it consists of an ECU and many sensors. It was first seen in engines produced by Renault (Renault 21, 25, and Espace) in 2.0 L (122 cu in) and 2.2 L (134 cu in) capacities. It is ...
The typical modern TCU uses signals from engine sensors, automatic transmission sensors and from other electronic controllers to determine when and how to shift. [2] More modern designs share inputs or obtain information from an input to the ECU, whereas older designs often have their own dedicated inputs and sensors on the engine components.
In the system, air flow into the engine is measured by a moving vane (indicating engine load) known as the volume air flow sensor (VAF) — referred to in German documentation as the LuftMengenMesser or LMM. L-Jetronic used custom-designed integrated circuits, resulting in a simpler and more reliable engine control unit (ECU) than the D ...
