For example, if the static compression ratio is 10:1, and the dynamic compression ratio is 7.5:1, a useful value for cylinder pressure would be 7.5 1.3 × atmospheric pressure, or 13.7 bar (relative to atmospheric pressure). The two corrections for dynamic compression ratio affect cylinder pressure in opposite directions, but not in equal strength.
Hybrid turbocharger with typical 3.5-5.0 bar boost pressure: Fuel system: 500 bar (7,252 psi) gasoline ... The V6 turbo engine was developed under the direction of ...
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 ...
Boost gauge on a Ford Focus RS (left) 30 psi Boost gauge Top: Turbo/APC boost gauge in a Saab 900. A boost gauge [1] is a pressure gauge that indicates manifold air pressure or turbocharger or supercharger boost pressure [2] in an internal combustion engine. They are commonly mounted on the dashboard, on the driver's side pillar, or in a radio ...
Peak engine pressure 130 bar (1,900 psi) Air delivery Forced induction, 2x twin scroll turbochargers spinning to 186,000 rpm with electronically controlled blow-off valves Fuel delivery Electronically controlled direct petrol injection with spray-guided combustion, fully variable, fuel pressure 100–200 bar (1,500–2,900 psi)
A compressor map is a chart which shows the performance of a turbomachinery compressor. This type of compressor is used in gas turbine engines, for supercharging reciprocating engines and for industrial processes, where it is known as a dynamic compressor. A map is created from compressor rig test results or predicted by a special computer program.

The Ferrari 126C engine, dubbed the Tipo 021/1, was designed to replace the highly successful but obsolete flat-12 used in the 312T series in use since 1975.The V6 engine used forced induction, better suiting the ground effect aerodynamics now needed to be competitive (the previous car's wide flat-12 boxer engine obstructed the airflow necessary to generate efficient ground effect), and was a ...
