A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM).

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 began production in 1974, and went into mass production in 1975. It subsequently went through several model iterations.
The OM646 engine is sold under the 200 CDI and 220 CDI designation and features an electric fuel pump, exhaust gas recirculation, particulate filters, [1] and Euro 4 emission standard compliance (from 2003). [2] In 2006, the engine was updated under the EVO name and replaced the OM647 engine.
The motor from a 3.5 in floppy disk drive. The coils, arranged radially, are made from copper wire coated with blue insulation. The rotor (upper right) has been removed and turned upside-down. The gray ring inside its cup is a permanent magnet. This particular motor is an outrunner, with the stator inside the rotor. DC brushless ducted fan. The ...
The 9-3 received some revisions in 2011 for the 2012 model year. Changes were in the engine range with an overall reduction in diesel and petrol engine fuel consumption of 12% and 7% respectively. [32] An entry-level 163 hp, 2.0 L gasoline/BioPower engine was added for 9-3 saloon, estate, and 9-3X models with Saab XWD.
This engine family was updated in 1968 for the use of 2.45 in (62.2 mm) medium-sized journals. The first engine in this family was the small journal 327 in 1962 and the last being 2000s medium journal 350 in pickup trucks and commercial vehicles. The medium journal 350 was further developed into the Generation II LT1/4 350 in the early 1990s.
Enigma was designed to be secure even if the rotor wiring was known to an opponent, although in practice considerable effort protected the wiring configuration. If the wiring is secret, the total number of possible configurations has been calculated to be around 3 × 10 114 (approximately 380 bits); with known wiring and other operational ...
