Volvo began offering a 4.4 L (4,414 cc) V8 engine in its large P2 platform automobiles in 2005. [6] [7] It was initially offered only for the Volvo XC90 [6] [7] but later found its way in the second generation Volvo S80, [5] and was mated to a six speed Aisin Seiki AWTF80-SC transmission of Japan also with a Swedish Haldex all-wheel drive (AWD) system.
Turbochargers and superchargers are both engine-driven air compressors (exhaust-driven or mechanically driven, respectively) and provide varying levels of boost according to engine rpm, load etc. [4] Quite often there is a power band within a given range of available boost pressure and it is an aid to performance driving to be aware of when ...
The MAP sensor is then used for rationality checks and to test the EGR valve. The way they do this is during a deceleration of the vehicle when there is low absolute pressure in the intake manifold (i.e., a high vacuum present in the intake manifold relative to the outside air) the powertrain control module (PCM) will open the EGR valve and ...
The Volvo XC90 is a mid-size luxury SUV [1] [2] manufactured and marketed by Volvo Cars since 2002 and now in its second generation.. The first generation was introduced at the 2002 North American International Auto Show and used the Volvo P2 platform shared with the first generation Volvo S80 and other large Volvo cars.
Distancing the supercharger from the engine via a mounting bracket greatly reduces heat transfer from the engine to the supercharger during operation. By comparison, a twin screw or roots blower which is nested in the center (valley) of the engine, will absorb heat (heat soak) during operation due to thermal transfer from the engine block and ...
A throttle position sensor (TPS) is a sensor used to monitor the throttle body valve position for the ECU of an engine. The sensor is usually located on the butterfly spindle/shaft, so that it can directly monitor the position of the throttle. More advanced forms of the sensor are also used.
A map is created from compressor rig test results or predicted by a special computer program. Alternatively the map of a similar compressor can be suitably scaled. This article is an overview of compressor maps and their different applications and also has detailed explanations of maps for a fan and intermediate and high-pressure compressors ...
A more successful application was in the RF series diesel engine found in the 1988 Mazda 626 Capella; ultimately 150,000 Mazda diesel cars were fitted with a Comprex supercharger. Other users included Peugeot, Opel and Mercedes-Benz. The Greenpeace SmILE concept car uses a Hyprex pressure wave supercharger developed by the Swiss company Wenko ...
