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 ML ...

Volvo 850
The Volvo 850 is a compact executive car that was produced by the Swedish manufacturer Volvo Cars from 1991 until 1996. Designed by Jan Wilsgaard, the car was introduced in a saloon body style; an estate style was introduced in 1993. The Volvo 850 was shown for the first time in June 1991, and the car marked a departure for Volvo, featuring multiple unprecedented features for the company; these included a transverse 5-cylinder engine driving the front wheels, a Delta-link rear axle, a side impact protection system, and a self-adjusting front seat belt mechanism. The Volvo 850 was succeeded by the Volvo S70 and Volvo V70. Models Development of what would become the 800 series first began in 1978. The so-called ''Project Galaxy'' ultimately resulted in the Volvo 850, the smaller 400 series, new manufacturing technologies as well as the Volvo Modular engine and M Gearbox lines. When development had finished, Volvo had spent the highest sum in the history of the country on an ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BMW M20
The BMW M20 is a SOHC straight-six petrol engine which was produced from 1977 to 1993. It was introduced eight years after the larger BMW M30 straight-six engine, which remained in production alongside the M20. The first cars to use the M20 were the E12 5 Series and the E21 3 Series. The initial M20 model had a displacement of , with later versions having displacements of up to . The M20 began to be phased out following the introduction of the M50 engine in 1990. The final M20 engines were fitted to the E30 3 Series wagon (estate) and convertible model built in April 1993. The M20 was the basis for the BMW M21 diesel engine. It is also loosely related to the BMW M70 V12 petrol engine. History By the 1970s, BMW felt the need for a six-cylinder engine smaller than the BMW M30, to use in the 3 Series and 5 Series. The resulting M20 had a displacement of , BMW's smallest straight-six engine of its day. BMW presented the M20 engine at the 1977 IAA as a 90 kW 2.0-litre Sol ...

BMW M44
The BMW M44 is a DOHC four-cylinder petrol engine which replaced the BMW M42 and was produced from 1996 to 2000 at the Steyr factory. It was produced alongside the BMW M43 SOHC four-cylinder engine, with the M44 being the higher performance engine. In 2000, the M44 was replaced by the BMW N42 engine. Design Compared with the M42, the M44 has roller rocker arms, a hot-wire MAF, displacement increased from and other detail changes such as a grey casst iron crankshaft replacing the forged steel item from the previous M42. As per the final versions of the M42, the M44 has a dual length intake manifold ("DISA"). Peak power is the same as the M42, however mid-range power is increased significantly and peak torque is increased by at 200 rpm lower. There was also a 70% reduction in valve train friction which contributed to the engine being more quiet and fuel efficient than its predecessor. The M44 has a cast iron block and aluminium cylinder head, as per its predecessor. Vers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BMW M50
The BMW M50 is a straight-6 DOHC petrol engine which was produced from 1990 to 1996. It was released in the E34 520i and 525i, to replace the M20 engine. In September 1992, the M50 was upgraded to the M50TU ("technical update"), which was BMW's first engine to use variable valve timing. Called single VANOS by BMW, the system adjusted the phasing of the intake camshaft. The M50 began to be phased out following the introduction of the M52 engine in 1994. The E36 M3 is powered by the S50 engine series, which is a high output version of the M50. Design A significant advance over its M20 predecessor, the M50 features dual overhead camshaft (DOHC) with four valves per cylinder (the M20 has a single overhead camshaft with 2 valves per cylinder), coil-on-plug ignition, a knock sensor and a lightweight plastic intake manifold. Both engines use an iron block with an aluminum alloy head. The redline is 6,500 rpm for the M50B25 and 6,750 rpm for the M50B20 (7,000 r ...

Volvo 960
The Volvo 900 Series is a range of executive cars produced by the Swedish manufacturer Volvo Cars from 1990 to 1998. The 900 Series was introduced in 1990 to replace the 700 Series from which it derived. Prior to the end of its production, the 960 was renamed as the Volvo S90 (saloon) and Volvo V90 (estate), and the 940 was renamed 940 Classic, becoming the last rear-wheel-drive cars from Volvo. Visible differences between the 700 and the 900 Series included redesigned rear styling of the saloon models (late 700 estates and early 900 estates are visually identical). The 960 was introduced in 1991 along with a new family of modular engines, and then was substantially revised for the 1995 model year, improving the handling. The range was augmented by the new Volvo 850 in 1991. The last of the 900s was sold in 1998. Some 900 Series were built as chassis for ambulances and hearses after the main production run had been completed. __TOC__ Volvo 940 The Volvo 940 is among the la ...

Alfa Romeo V6 Engine
The Alfa Romeo V6 engine (also called the Busso V6) is a 60° V6 engine made by Alfa Romeo from 1979 to 2005. It was developed in the early 1970s by Giuseppe Busso, and used on the Alfa 6 with a displacement of and a SOHC 12-valve cylinder head. Later versions ranged from and had DOHC 24-valve valvetrains. The original design had short pushrods for the exhaust valves in a design similar to earlier Lancia Fulvia engines. The first DOHC version was in the 1993 Alfa Romeo 164, with an aluminium alloy engine block and head with sodium filled exhaust valves. The Alfa Romeo V6 has been used in kit cars like the Ultima GTR, Hawk HF Series, and DAX, as well as the Gillet Vertigo sports car and the Lancia Aurelia B20GT Outlaw. https://www.thornleykelham.com/wp-content/uploads/2022/03/The-final-3-Outlaws.pdf In August 2011 EVO magazine wrote that "the original Alfa Romeo V6 was the most glorious-sounding six-cylinder road engine ever," The Alfa Romeo V6 engine has also been used in ...

Lambda Sensor
An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) or probe or sond, is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analysed. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Dr. Günter Bauman. The original sensing element is made with a thimble-shaped zirconia ceramic coated on both the exhaust and reference sides with a thin layer of platinum and comes in both heated and unheated forms. The planar-style sensor entered the market in 1990 and significantly reduced the mass of the ceramic sensing element, as well as incorporating the heater within the ceramic structure. This resulted in a sensor that started sooner and responded faster. The most common application is to measure the exhaust-gas concentration of oxygen for internal combustion engines in automobiles and other vehicles in order to calculate and, if required, dynamically adj ...

Jetronic
Jetronic is a trade name of a manifold injection technology for automotive petrol engines, developed and marketed by Robert Bosch GmbH from the 1960s onwards. Bosch licensed the concept to many automobile manufacturers. There are several variations of the technology offering technological development and refinement. D-Jetronic (1967–1979) Analogue fuel injection, 'D' is from german: "Druck" meaning pressure. Inlet manifold vacuum is measured using a pressure sensor located in, or connected to the intake manifold, in order to calculate the duration of fuel injection pulses. Originally, this system was called Jetronic, but the name D-Jetronic was later created as a retronym A retronym is a newer name for an existing thing that helps differentiate the original form/version from a more recent one. It is thus a word or phrase created to avoid confusion between older and newer types, whereas previously (before there were ... to distinguish it from subsequent Jetronic iterations. D-J ...

Engine Control Unit
An engine control unit (ECU), also commonly called an engine control module (ECM), is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance. It does this by reading values from a multitude of sensors within the engine bay, interpreting the data using multidimensional performance maps (called lookup tables), and adjusting the engine actuators. Before ECUs, air–fuel mixture, ignition timing, and idle speed were mechanically set and dynamically controlled by mechanical and pneumatic means. If the ECU has control over the fuel lines, then it is referred to as an electronic engine management system (EEMS). The fuel injection system has the major role of controlling the engine's fuel supply. The whole mechanism of the EEMS is controlled by a stack of sensors and actuators. Workings Control of air–fuel ratio Most modern engines use some type of fuel injection to deliver fuel to the cylinders. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
