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.
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 ...
The G16E-GTS is a turbocharged engine model with 10.5:1 compression ratio and D-4ST direct/port injection system with multi-oil jet piston cooling, large-diameter exhaust valves and a part-machined intake port. The turbo boost is set between 1.4 and 1.81 bar (20.3 and 26.3 psi).

The high-performance turbocharged 1,995 cc (2.0 L) 20A4E engine with central direct injection has 79 mm × 81.5 mm (3.11 in × 3.21 in) bore and stroke, with cylinder pressure of 130 bar (1,900 psi) and compression ratio of 9.5:1 for Performance version and 10.5:1 for Eco version is developed and manufactured by Chinese Saic Motor company.
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 ...
Single-turbocharged by Garrett Advancing Motion with 3.5 bar (51 psi) of turbo boost pressure: Fuel system: Bosch HDEV6 350 bar (5,076 psi) central high-pressure gasoline direct fuel injection. One direct injector per cylinder fed by an engine-driven high-pressure fuel pump: Management: Bosch Motronic MS 7.4: Fuel type: Various (102 RON ...
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.
