An external wastegate requires a specially constructed turbo manifold with a dedicated runner going to the wastegate. The external wastegate may be part of the exhaust housing itself. External wastegates are commonly used for regulating boost levels more precisely than internal wastegates in high power applications, where high boost levels can ...
The BorgWarner developed turbo can produce up to 27 psi (1.9 bar) of boost thanks in part to its unique dual volute turbine housing and an electrically actuated wastegate. Instead of two side-by-side exhaust passages like on a regular twin-scroll turbocharger , in this design the two exhaust passages are concentric and allow for better use of ...
Ford F-Series (full-size pickup trucks) Mid-1994 – Mid-2003 7.3 L [30] ... (119 kW) (wastegate turbo), is the electronic version of the Power Stroke. It has only ...
The first version of this engine family was a normally aspirated 2.2 L (134 cu in) unit. Developed under the leadership of Chief Engineer – Engine Design and Development Willem Weertman and head of performance tuning Charles "Pete" Hagenbuch, who had worked on most of Chrysler's V-8 engines and the Chrysler Slant-6 engine, [1] it was introduced in the 1981 Dodge Aries, Dodge Omni, Plymouth ...
The GM E-Turbo engine is a gasoline-fueled engine developed by General Motors as part of the company’s next-generation turbocharged engine family. The engine features a start-stop system , gasoline direct injection , an electric water pump and an electric turbocharger wastegate to optimize fuel efficiency .
Saab Full Pressure Turbo (FPT) models with this unit include the APC name displayed on a non-numeric boost pressure gauge in the instrument panel. Although knock sensors are common even on non-turbocharged and turbocharged engines today, Saab has continued to use the APC name prominently as a differentiating feature.
In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement .
Still, the turbocharger improves the engine's thermal efficiency, resulting in a BSFC of 245 g/(kW·h), an improvement of ca. 20 g over the naturally aspirated version. [7] The original performance figures for the 2998 cm 3 unit were 85 kW at 4200/min [ 8 ] and a BMEP of 1.0 MPa, [ 6 ] equivalent to a maximum torque of ca. 235 N·m at 2400/min ...
