BMW M70
The BMW M70 is a Naturally aspirated engine, naturally-aspirated, Overhead camshaft#Single overhead camshaft, SOHC, V12 engine, V12 petrol engine, which was BMW's first production V12 and was produced from 1987 to 1996. It was also the first German 12-cylinder post-war automobile engine, predating Mercedes-Benz M120 engine, Mercedes-Benz's M120 by four years and VAG's Volkswagen Group W-12 engine, W12 by fourteen. The BMW S70/2 engine, largely unrelated to the M70 and S70B56 engines, is a naturally-aspirated, Overhead camshaft#Dual overhead camshaft, DOHC, V12 petrol engine, which powered the 1993 to 1998 McLaren F1. Design The M70's design is similar to that of two 2.5 L BMW M20, M20 straight-six engines joined at a 60-degree angle, due to the following features: Overhead camshaft#Single overhead camshaft, single overhead camshaft valvetrain, bore spacing of , bore (engine), bore of , stroke (engine), stroke of , and a compression ratio of 8.8:1. The M70 has the following differ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V12 Engine
A V12 engine is a twelve-Cylinder (engine), cylinder Internal combustion engine#Reciprocating engines, piston engine where two banks of six cylinders are arranged in a V engine, V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in Boat racing, racing boats. Due to the balanced nature of the engine and the smooth delivery of Engine power, power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, after which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars. Design Balance and smoothness Each bank of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Throttle Control
Electronic throttle control (ETC) is an Automotive engineering, automotive technology that uses electronics to replace the traditional mechanical linkages between the driver's input such as a Car controls#Throttle control, foot pedal to the vehicle's throttle mechanism which regulates speed or acceleration. This concept is often called drive by wire, and sometimes called accelerate-by-wire or throttle-by-wire. Operation 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). The ECM is a type of electronic control unit (ECU), which is an embedded system that employs software to determine the required throttle position by calculations from data measured by other sensors, including the accelerato ...

BMW 7 Series (E32)
The BMW E32 is the second generation of the BMW 7 Series luxury cars and was produced from 1986 until 1994. It replaced the E23 and was initially available with straight-six or V12 powerplants. In 1992, V8 engines became available. From its inception, the E32 was among the most technologically advanced cars in its day. The E32 introduced numerous features including adaptive suspension (EDC), traction control, two available wheelbases (i and iL), and dual-zone climate control.

Other automotive passenger vehicles features introduced with the E32 included: projector lens headlamps (1986); double glazed windows (1991); HID (Xenon) headlamps (1991). E32 also introduced BMW's first V8 engine since the BMW 501/502, last produced in 1962, and their first V12 engine, which was also the first German car to have a V12 engine since the 1939 Maybach Zepp ...

Alternator
An alternator (or synchronous generator) is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature.Gordon R. Selmon, ''Magnetoelectric Devices'', John Wiley and Sons, 1966 no ISBN pp. 391-393 Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called an alternator, but usually, the term refers to small rotating machines driven by automotive and other internal combustion engines. An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators. Large 50 or 60 Hz three-phase alternators in power plants generate most of the world's electric power, which is distributed by electric power grids. History ...

Engine Control Unit
An engine control unit (ECU), also called an engine control module (ECM), 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. The earliest ECUs (used by aircraft engines in the late 1930s) were mechanical-hydraulic units; however, most 21st-century ECUs operate using digital electronics. Functions The main functions of the ECU are typically: * Fuel injection system * Ignition system * Idle speed control (typically either via an idle air control valve or the electronic throttle system) * Variable valve timing and/or variable valve lift systems The sensors used by the ECU include: * accelerator pedal position sensor * camshaft position sensor * coolant temperature sensor * crankshaft position sensor * knock sensors * inlet manifold pressure sensor ( MAP sensor) * intake air temperature * intake air mass flow rate sensor ( MAF sensor) * oxygen (lambda) s ...

Motronic
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, and emissions) can be improved. Motronic 1.x Motronic M1.x is powered by various i8051 derivatives made by Siemens, usually SAB80C515 or SAB80C535. Code/data is stored in DIL or PLCC EPROM and ranges from 32k to 128k. 1.0 Often known as "Motronic basic", Motronic ML1.x was one of the first digital engine-management systems developed by Bosch. These early Motronic systems integrated the spark timing element with then-existing Jetronic fuel injection technology. It was originally developed and first used in the BMW 7 Series, before being implemented on several Volvo and Porsche engines throughout the 1980s. The components of the Motronic ...
