The N53 uses the same High-Pressure Fuel Pump (HPFP) as the BMW N54 turbocharged straight-six engine, [12] which had HPFP failures leading to Lemon Law "buy backs" and legal action in the United States. The N53 engine was not sold in the United States, therefore the N53 engine was not involved with these actions.
It is similar to that of a piston pump, but the high-pressure seal is stationary while the smooth cylindrical plunger slides through the seal. Plunger-type pumps are often mounted on the side of the injection pump and driven by the camshaft. [4] These pumps usually run at a fuel pressure of 3,600–26,100 psi (250–1,800 bar). [3]
The final model powered by the N54 is the E89 Z4 roadster, which was produced until 2016. The N54 has won six straight International Engine of the Year awards [2] and three straight Ward's 10 Best Engines awards. [3] There is no BMW M version of the N54, however a high-output version of the N54 is used in the 1 Series M Coupe, Z4 35iS and 335iS ...
A gasoline pump or fuel dispenser is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers (in Australia and South Africa), [2] [3] petrol pumps (in Commonwealth countries), or gas pumps (in North America).
Furthermore, vane pumps can be used in low-pressure gas applications such as secondary air injection for auto exhaust emission control, or in low-pressure chemical vapor deposition systems [citation needed]. Rotary-vane pumps are also a common type of vacuum pump, with two-stage pumps able to reach pressures well below 10 −6 bar.
The S55 engine is the high performance engine developed from the N55 by BMW M. It was introduced in the F80 M3 and F82 M4 replacing the BMW S65 naturally aspirated V8 engine used in the previous generation M3 and was later used in the F87 M2 Competition/CS .

Breathing gas blending for underwater diving where the gas is to be supplied from high-pressure cylinders, as in scuba, scuba replacement and surface-supplied mixed gas diving, where the component gases are blended by partial pressure addition to the storage cylinders, and the mixture storage pressure may be higher than the available pressure ...
