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] |

Trionic 8
The Trionic 8 is an advanced engine management system in the Trionic series, created by Saab Automobile. It is used in both Saab 9-3 and Opel Vectra vehicles, and is available with 150, 175 and engines. It will also be used for a flexifuel version starting production spring 2007. Saab Trionic T8 has been developed by Saab and is a very advanced engine management system. The Engine Control Module (ECM) is used principally to regulated the air mass, fuel and ignition timing. Functionality Trionic monitors ionization rates at each spark plug to individually control and adjust the combustion process for each cylinder. Other primary functions are: * Ignition timing * Fuel injection * Turbo boost pressure * Air mass measurement * Throttle Throttle regulation Trionic 8 calculates how much power the driver wants as early as possible to avoid turbo kick or lag, therefore making driving smooth. As the driver depresses the accelerator pedal, it acts on a pedal position sensor integrated i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saab 9-3
The Saab 9-3 (pronounced ''nine-three'') is a compact executive car initially developed and manufactured by the Swedish automaker Saab. The first generation 9-3 (1998-2003) is based on the GM2900 platform, changing to the GM Epsilon platform with the introduction of the second-generation car (2003-2012). Other vehicles using this platform include the Opel Vectra, Chevrolet Malibu, and Cadillac BLS. Saab's last owners, National Electric Vehicle Sweden (NEVS), assembled the 9-3 sedan as Saab's only model. Overview The car was badged as 93 starting in the 1998 model year when Saab revised the naming strategy of their small car to match that of their larger 95. The model was marketed as 9-3, pronounced as "nine three.” The Saab 9-3 was launched in 1998 for the 1999 model year essentially as a rebadged second-generation Saab 900 (1994–1998 model) and succeeded by a redesigned 9-3 for the 2003 model year. It is not to be confused with the Saab 93 (pronounced "ninety-th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saab H Engine
The Saab H engine is a redesign of the Saab B engine, which in turn was based on the Triumph Slant-4 engine. Despite the name it is not an H engine or horizontally opposed engine, but a slanted inline-4. The H engine was introduced in 1981 in the Saab 900 and was also used in the Saab 99 from 1982 onwards. H stood for high compression; higher compression was part of the update from B to H engine. It continued in use in the 900/ 9-3, 9000, and 9-5. The 2003 GM Epsilon-based 9-3 switched to the GM Ecotec engine, leaving the 9-5 as the sole user of the H engine. The H family of engine was used in the first-generation 9-5 until it was discontinued in 2010. The tooling and know-how was sold to BAIC. The latter B2X4 and B2X5 engines have in practice nothing in common with the early B engines except cylinder spacing. All versions feature a grey cast iron block and an aluminum head with a single or double overhead chain driven camshafts. SOHC engines use two valves per cylinder an ...

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 ...

Saab Automobile
Saab Automobile AB () is a defunct car manufacturer that was founded in Sweden in 1945 when its parent company, Saab AB, began a project to design a small automobile. The first production model, the Saab 92, was launched in 1949. In 1968 the parent company merged with Scania-Vabis, and ten years later the Saab 900 was launched, in time becoming Saab's best-selling model. In the mid-1980s the new Saab 9000 model also appeared. In 1989, the automobile division of Saab-Scania was restructured into an independent company, Saab Automobile AB. The American manufacturer General Motors (GM) took 50 percent ownership. Two well-known models to come out of this period were the Saab 9-3 and the Saab 9-5. Then in 2000, GM exercised its option to acquire the remaining 50 percent. In 2010 GM sold Saab Automobile AB to the Dutch automobile manufacturer Spyker Cars N.V. After many years establishing a sound engineering reputation and ultimately a luxury price tag, Saab failed to buil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saab 900
The Saab 900 is a mid-sized automobile which was produced by Saab from 1978 until 1998 in two generations; the first from 1978 to 1993, and the second from 1994 to 1998. The first-generation car was based on the Saab 99 chassis, though with a longer front end . The 900 was produced in 2- and 4-door sedan, and 3- and 5-door hatchback configurations and, from 1986, as a cabriolet (convertible) model. There were single- and twin- Zenith carburettor; fuel injected, and turbocharged engines, including both Full Pressure Turbo (FPT), and, in European models during the early 1990s, Low Pressure Turbos (LPT). Saab 900 "Classic" Overview The Saab 900 is a front-engine, front-wheel-drive mid-size car with a longitudinally mounted, 45-degree slanted, inline four-cylinder engine, double wishbone front suspension and beam-axle rear suspension.

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 cylind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Automatic Performance Control
Automatic Performance Control (APC) was the first engine knock and boost control system. The APC was invented by Per Gillbrand at the Swedish car maker SAAB. SAAB introduced it on the turbo charged Saab H engines in 1982, and the APC was fitted to all subsequent 900 Turbos through 1993 (and 1994 convertibles), as well as 9000 Turbos through 1989. The APC was sold to Maserati to equip the carbureted Maserati Biturbo, with different settings for the Biturbo, and was known as the Maserati Automatic Boost Controller (MABC). The APC allowed a higher compression ratio (initially, 8.5:1 as opposed to 7.2:1, and, on 16-valve variants introduced in 1985, 9.0:1). This improved fuel economy and allowed the use of low-octane petrol without causing engine damage caused by knock. The APC controls boost pressure and the overall performance, specifically the rate of rise and maximum boost level - and it detects and manages harmful knock events. To control the turbocharger, the APC moni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saab Information Display
Saab Information Display (SID) later also called "Saab Car Computer"1995 Saab 900SE owner's manual (SCC) is the name for various in-car computer systems found on most Saab automobiles beginning in 1985 with the Saab 9000 and followed in 1994 with the Saab 900 NG. SIDs typically provide functions useful to the driver such as multiple trip odometers, fuel efficiency, estimated range ("distance to empty" – DTE), current CD track or radio station, and also brief description of car system failures. SIDs designed prior to the full General Motors takeover of Saab in 2000 were mounted in the center console, usually just above the head unit and below climate control vents with the exception of 9000 models, possibly after the "facelift" in the early 1990s. The 9000 featured the SID on the standard instrument cluster, with a car pictogram, showing open doors/tailgate/boot (trunk), lamp failures and low oil pressure in red. If there were no warnings, the white pictogram would disappear. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pulse-width Modulation
Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a method of reducing the average power delivered by an electrical signal, by effectively chopping it up into discrete parts. The average value of voltage (and current) fed to the load is controlled by turning the switch between supply and load on and off at a fast rate. The longer the switch is on compared to the off periods, the higher the total power supplied to the load. Along with maximum power point tracking (MPPT), it is one of the primary methods of reducing the output of solar panels to that which can be utilized by a battery. PWM is particularly suited for running inertial loads such as motors, which are not as easily affected by this discrete switching, because their inertia causes them to react slowly. The PWM switching frequency has to be high enough not to affect the load, which is to say that the resultant waveform perceived by the load must be as smooth as possible. The rate (or frequency) ...
