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.
If the unit had no variable geometry, there would be handling problems, because the surge line would be very steep and cross the working line at part-flow. During a slam-acceleration from a mid-throttle setting, the compressor working line will move rapidly towards surge and then slowly approach the steady state operating point, further up the map.
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.
MAP sensor data can be converted to air mass data by using a second variable coming from an IAT Sensor (intake air temperature sensor). This is called the speed-density method. Engine speed (RPM) is also used to determine where on a look up table to determine fuelling, hence speed-density (engine speed / air density).
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 pressure wave supercharger (also known as a wave rotor [1]) is a type of supercharger technology that harnesses the pressure waves produced by an internal combustion engine exhaust gas pulses to compress the intake air. Its automotive use is not widespread; the most widely used example is the Comprex, developed by Brown Boveri. [2] [3] [4]
An Eaton M62 Roots-type supercharger is visible at the front of this Ecotec LSJ engine in a 2006 Saturn Ion Red Line.. The Roots-type blower is simple and widely used. It can be more effective than alternative superchargers at developing positive intake manifold pressure (i.e., above atmospheric pressure) at low engine speeds, making it a popular choice for passenger automobile applications.
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.
