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.
A Dual VVT-i equipped version was later introduced and first used in Toyota Avanza and in many 1.5L models in the Asian market from the 2017 model year. [2] Technical specifications of the engine: Displacement: 1.5 L (1,496 cc) Bore x Stroke: 72.5 mm × 90.6 mm (2.85 in × 3.57 in) Max. output:
The mean effective pressure (MEP) is a quantity relating to the operation of a reciprocating engine and is a measure of an engine's capacity to do work that is independent of engine displacement. [1] Despite having the dimension of pressure, MEP cannot be measured. [ 2 ]
GM claims that the 1.0-liter turbo is 25 percent (3 dBA) quieter than the Ford Fiesta's 1.0-liter turbo, and the 1.4-liter is up to 50 percent (6 dBA) quieter than the VW/Audi 1.4-liter turbo. Other silencing measures include a bed-plate cylinder block that increases stiffness and a stiffened aluminum front cam cover.
The BMW B38 is a 1.2 and 1.5 L (1,198 and 1,499 cc) turbocharged straight-three DOHC petrol engine, which replaced the straight-four BMW N13.Production started in 2013. It is part of a modular BMW engine family, of straight-three (B38), straight-four and straight-six alloy block and head petrol engines, [1] which use a displacement of 400 cc (24.4 cu in) per cylinder in the 1.2 and 500 cc (30. ...
As of 2010, the L15A7 (i-VTEC) is a class legal engine choice for SCCA sanctioned Formula F competition, joining the 1.6L Ford Kent engine. [ 1 ] In 2016 Honda introduced the L15B (DOHC-VTC-TURBO-VTEC) engine as part of their continuing global earth dreams strategy for lower emissions and higher fuel economy for a range of their cars, available ...
The 5L-E is a 3.0 L (2,985 cc) EFI version of the 5L engine. It is the latest member of the L family. It is the latest member of the L family. It has a bore and stroke of 99.5 mm × 96 mm (3.92 in × 3.78 in), with a compression ratio of 22.2:1.
The 1.1 L (1,120 cc) U diesel engine is a 3-cylinder version of the 1.5L U series unit and is made with cast iron block and aluminum cylinder head with chain driven DOHC with 4 valves per cylinder, Delphi common rail direct injection (CRDi), variable geometry turbocharger (VGT) and intake air swirl control.
