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.
An ECU from a Geo Storm. 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 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 can control the ignition and fuel injection. It does not contain built-in power drivers for ignition coils, fuel injectors and idling air control (IAC) valve. External drivers must be used. SECU-3L. [3] It was designed for ignition control only and it can be considered as a light version of the SECU-3T unit.
The part number of a pole piece and plate assembly can be dete3rmined by visual inspection by the colored ties or connectors ant he number of teeth on the timer core and pole piece. The following is a list of pole piece and plate assemblies by pick-up coil color code. Blue tie or black connector body: 1876210 (V-8), 1891209 (V-6), 1880020 (L-4)
Motronic is the trade name given to a range of digital engine control units developed by Robert Bosch GmbH (commonly known as Bosch) which combined control of fuel injection and ignition in a single unit. By controlling both major systems in a single unit, many aspects of the engine's characteristics (such as power, fuel economy, drivability ...
A power-train control module, abbreviated PCM, is an automotive component, a control unit, used on motor vehicles. It is generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the TCU, and the Body Control ...
Of all the electronics in any car, the computing power of the engine control unit is the highest, typically a 32-bit processor. [citation needed] A modern car may have up to 100 ECU's and a commercial vehicle up to 40. [citation needed] An engine ECU controls such functions as: In a diesel engine: Fuel injection rate; Emission control, NOx control
