Direct
fuel injection sprays fuel directly into the cylinders, or more precisely the combustion chambers.
That's achieved by precisely controlling the mixture motion and
fuel injection spray pattern.
Not exact matches
Gasoline direct
injection involves
spraying high - pressure liquid gasoline directly into the engine cylinder rather than mixing and vaporizing the
fuel in the intake port outside the cylinder.
In direct
Injection, the injector
sprays the air
fuel mixture directly into the cylinder thus you have optimum computer controlled combustion.
I forget who, but some manufacturer has a small injector that
sprays a tiny bit of gas in like regular
fuel injection to keep the valves clean.
Sequential Multi-port Electronic

High - pressure direct -
injection (2,900 psi / 200 bar) with multi-hole
fuel injectors provide a more even
spray.

This dual injector system allows a wider
injection of
fuel, with the smaller nozzles delivering a finer
spray (approximately 57 percent finer than the previous generation single injector design's particle size) to help achieve stable combustion.
The common rail
injection system has also undergone further development: it has a maximum operating pressure of 2,000 bar and can therefore inject
fuel in an extremely precise
spray pattern.
Its advanced six - cylinder engine featuring piezoelectric direct
injection and
spray - guided combustion generates 215 kW / 292 hp and returns impressively low
fuel consumption figures of 9.1 to 9.3 litres per 100 kilometres (NEDC combined).
The engine block is newly designed to reduce mechanical friction and achieve an optimal air -
fuel mix, and a direct
fuel injection system is employed due to the wide variety of
spray profiles that are possible, enabling the maximum expansion ratio to be achieved.
For 2018, numerous reversions were made to the 5.0, most notably the adoption of a port and direct
fuel injection system, as well as
spray - on bore liner, eliminating the need for conventional cylinder liners (changes shared with the 2018 Mustang).
One of the key features of the new LR - V8 is an industry first, centrally - mounted, multi-hole,
spray - guided
fuel injection system, delivering
fuel at a pressure of up to 150bar (2,175 psi) directly to the cylinder.
Direct
fuel injection, which
sprays fuel directly into the cylinder to mix with incoming air.
Spray - guided direct
fuel injection with piezo injectors, all - aluminum crankcase, four - valve - per - cylinder design with camshaft adjustment, an air - water intercooler, alternator management, ECO start / stop function and gliding mode have all been retained.
Higher
fuel -
injection pressure results in an improved
injection spray, helping reduce raw hydrocarbon emissions in a cold engine.
One of the secrets of the V8's efficiency is the centrally - mounted, multi-hole,
spray - guided
fuel injection system delivering
fuel at a pressure of up to 2175psi (150bar) directly to each cylinder.
Like the current generation of technically advanced Ecotec engines, the 2.5 L also features a high pressure direct
injection fuel system, dual overhead camshafts with continuously variable valve timing, electronic throttle control, and pistons with jet -
spray oil cooling.

Declaring that a few per cent less
fuel consumption throughout an entire model range gives the public and society in general more than a significant improvement of
fuel economy on just one niche model, BMW has stated that it will implement
spray - guided direct
injection on all its gasoline models in the future, as well as regenerative braking and stop / start functionality.
For the
spray - guided combustion process, the engineers developed a special piezo
injection valve and a
fuel system with a high pressure of 200 bar.
The engine features dual overhead camshafts with continuously variable valve timing and increased - authority cam phasing (increased phase rotation angle), a high - pressure returnless direct -
injection fuel system with camshaft - driven
fuel pump delivering 750 psi at idle and 2250 psi at full load, higher - flowing intake and exhaust ports in the cylinder head, electronic throttle control and pistons with jet -
spray oil cooling.
The engine benefits from higher
fuel injection pressure of 2,000 bar and more efficient piezo injectors with smaller holes for a finer
spray.
Direct
injection (DI) delivers a precise, fine mist of
fuel directly into each cylinder, unlike conventional port
fuel injection that
sprays into the intake system.
The engine includes a range of cutting - edge technologies, including a dual
fuel injector system that allows a wider
injection of
fuel (versus traditional single injector systems), with the smaller nozzles delivering a
spray approximately 57 percent finer than the previous generation single injector design's particle size to help achieve more complete combustion.
Note the while the engine has variable valve timing, it does not have gasoline direct
injection (GDI) where high - pressure
fuel is
sprayed directly into the combustion chambers.
