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 ...
GM has used KIVA in the development of direct-injection, stratified charge gasoline engines as well as the fast burn, homogeneous-charge gasoline engine. [30] Mercedes-Benz developed a prototype engine called DiesOtto, with controlled auto ignition. It was displayed in its F 700 concept car at the 2007 Frankfurt Auto Show. [33]
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).
mapped direct ignition with centrally mounted longlife spark plugs and eight individual direct-acting single spark coils; Bosch Motronic MED 9.1.1 electronic engine control unit (ECU) (two MED 9.1 ECUs in the RS 4 and R8, working on the 'master and slave' concept due to the high revving nature of the engine), four knock sensors, EU4 emissions ...
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.
Compared with its N52 predecessor which was port-injected, the N53 uses direct injection. The direct injection system uses piezoelectric fuel injectors which inject into the combustion chamber, using a stratified lean mixture operation. [2] The compression ratio was increased to 12.0:1 for the N53. [3]
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.
An all new cylinder head was needed for the Audi-developed Fuel Stratified Injection (FSI), which features cylinder-direct fuel injection straight into the combustion chambers. The result of needing to site both spark plug and fuel injector meant that the former five-valve layout had to be changed to a four-valve-per-cylinder arrangement.
