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 ...
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.
common-rail electronic multi-point Fuel Stratified Injection (FSI) homogeneous direct petrol injection, up to 110 bar high-pressure fuel pump, stratified-charge combustion at partial load aspiration two-position tumble flap in the intake manifold controlling the turbulence exhaust up to 35% exhaust gas recirculation, NOx storage-type catalytic ...
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 ...
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 ...
We break down how much it costs to charge an electric vehicle at home and at public charging stations. Plus, whether installing a level 2 charger is worth it.
Comparing Oral vs. Injectable Semaglutide. It’s hard to watch the news or scroll through social media without encountering stories about weight loss drugs like semaglutide (the active ingredient ...
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).
