Mercedes-Benz has been employing stratified charge engines with its Blue DIRECT system. With the stratified-charge application, the 3.0L V-6 will continue to employ direct fuel injection, but the injectors have been redesigned to spray under higher pressure later in the intake stroke, just before compression, and the fuel is shaped to arrive in ...
Gasoline direct injection (GDI), also known as petrol direct injection (PDI), [1] is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber. This is distinct from manifold injection systems, which inject fuel into the intake manifold (inlet manifold).
Typically, hydraulic direct injection systems spray fuel into the air inside the cylinder or combustion chamber. Direct injection can be achieved with a conventional helix-controlled injection pump, unit injectors, or a sophisticated common-rail injection system. The last is the most common system in modern automotive engines.
fully demand-controlled and returnless; – fuel tank–mounted low-pressure fuel pump; Fuel Stratified Injection (FSI): single-piston high-pressure injection pump driven by a four-lobe cam on the exhaust camshaft supplying up to 190 bar (2,760 psi) fuel pressure in the stainless steel common rail fuel rail, four combustion chamber sited direct ...
Modern direct injection diesel engines combine stratified charge (SC) with compression ignition (CI), abbreviated as SCCI. As in HCSI, HCCI injects fuel during the intake stroke. However, rather than using an electric discharge (spark) to ignite a portion of the mixture, HCCI raises density and temperature by compression until the entire ...
Why is the FDA recommending an intradermal injection for the monkeypox vaccine? The FDA is recommending that monkeypox vaccines be given intradermally to try to stretch out the current vaccine supply.
fully demand-controlled, (Q7 returnless, RS 4 return to tank); fuel tank–mounted low-pressure fuel pump; Fuel Stratified Injection (FSI): two inlet camshaft double-cam driven single-piston high-pressure injection pumps maintaining a pressure of between 30 and 100 bar (435 and 1,450 psi) in the two stainless steel common rail fuel distributor ...
