Trionic T5.2
The Trionic T5.2, an advanced engine management system in the Trionic series, was introduced in Saab 9000 year 1993 and was discontinued the same year. This engine management system was used on the "long block" engines. It was superseded by the Trionic T5.5 engine management system. Features Its Engine Control Unit is based on a Motorola 32 bit CPU A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and .... The Trionic T5.2 uses a Mecel patented ion-current measurement1 to decide which cylinder was in the compression phase and had just ignited the air/fuel mixture. The ion-current measurement is thus used to synchronise the ignition's firing of the spark plug with the cylinder which is full of compressed air/fuel. This ion-current measurement can also determine whether there had been de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Trionic
Trionic is an engine management system developed by Saab Automobile. It consists of an engine control unit (ECU) that controls 3 engine aspects: # Ignition timing # Fuel injection # Acts as a boost controller. The numerical prefix 'tri-' in Trionic. 'Ion' comes from the fact that it uses ion current, measured by the spark plugs between combustion events which acts as a sensor for knock, misfire and synchronization detection. The ion current stream which was developed within the ion sensing system due to combustion, can be deduced by monitoring the secondary current of the ignition coil. Using the value and wave shape of the current, after the actual spark event, the quality of the actual combustion process is determined, thus allowing the engine control unit to optimize the timing of the spark for the best engine performance while keeping emissions low on a much wider range of rpms. Since Trionic 7, the throttle and thereby the air charge has also been electronically controlled, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saab 9000
The Saab 9000 is an automobile produced by the Swedish company Saab from 1984 to 1998. Representing the company's foray into the executive car scene, it was developed as a result of the successes of the turbocharged 99 and 900 models. The 9000 remained in production until May 1998 and it was replaced by the Saab 9-5 in late 1997, although some final cars were produced into 1998. The Saab 9000 was only available with petrol engines, as 5-door hatchback or 4-door notchback and never as a convertible (except for one prototype) or a Coupé. Saab designed the 9000 as part of the Type Four platform in conjunction with the Italian automaker Fiat Automobiles. Fiat retailed similar derivative versions as the more basic Fiat Croma, the luxury-themed Lancia Thema, and the sports-oriented Alfa Romeo 164. Unlike the 164, which shares only the chassis, the Croma and Thema are outwardly similar to the 9000. As such, much of the bodywork appeared interchangeable between the 9000, Croma and Thema; ...

Motorola
Motorola, Inc. () was an American Multinational corporation, multinational telecommunications company based in Schaumburg, Illinois, United States. After having lost $4.3 billion from 2007 to 2009, the company split into two independent public companies, Motorola Mobility and Motorola Solutions on January 4, 2011. Motorola Solutions is the legal successor to Motorola, Inc., as the reorganization was structured with Motorola Mobility being spun off. Motorola Mobility was acquired by Lenovo in 2014. Motorola designed and sold wireless network equipment such as cellular transmission base stations and signal amplifiers. Motorola's home and broadcast network products included set-top boxes, digital video recorders, and network equipment used to enable video broadcasting, computer telephony, and high-definition television. Its business and government customers consisted mainly of wireless voice and broadband systems (used to build private networks), and, public safety communicat ...

Mecel
Mecel is a software and systems consulting firm, specializing in the automotive industry. The company has offices in Gothenburg and has approximately 120 employees. History Mecel was founded in Sweden in 1982 by Jan Nytomt and Hasse Johansson, who later became technical manager at Scania. The company idea was to provide the automotive industry with electronic engine control devices. In 1982, Saab-Scania Combitech Group, as the company was named at the time, acquired Mecel. When General Motors bought the Saab-Scania car operations in 1990, Mecel followed with it. In 1997, General Motors created the company Delphi Automotive Systems and subsequently Mecel became a wholly owned subsidiary of Delphi. Mecel has since been operating as an independent software and system house being able to offer services to all customers. In 1987, a software division, Mecel Gothenburg, was started in Chalmers University Science Park with the intention of investigating and developing multiplexed s ...

Engine Control Systems
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form, so heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine, in ...
