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 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. ...
2NR-VEX engine on a Toyota Yaris Cross. Based on the 1.5-litre 2NR-VE engine, the 2NR-VEX unit is an Atkinson cycle engine used with a hybrid system paired with an electric motor and a lithium-ion battery. Maximum output: 67 kW (90 hp; 91 PS) Maximum torque: 121 N⋅m (89 lb⋅ft) Applications: Toyota Yaris Cross Hybrid (NYC200, 2023–present) [8]
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.
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.
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. [1] It is commonly used as an expression of an engine's size, and by extension as an indicator of the power (through mean effective pressure and rotational speed ) an engine might be capable of producing ...
The first person to build a working four-stroke engine, a stationary engine using a coal gas-air mixture for fuel (a gas engine), was German engineer Nicolaus Otto. [4] This is why the four-stroke principle today is commonly known as the Otto cycle and four-stroke engines using spark plugs often are called Otto engines.
