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).
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 ...
Another form of direct impingement using a fluted chamber instead of a gas port. With this operation, the gas circumvents around the chambered cartridge through the grooves of the fluted chamber surpassing through the locking lugs to the front of the bolt carrier that operates as a gas piston unlocking the bolt to cycle the weapons operation.
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 ...
In firearms, a blowback system is generally defined as an operating system in which energy to operate the firearm's various mechanisms, and automate the loading of another cartridge, is derived from the inertia of the spent cartridge case being pushed out the rear of the chamber by rapidly expanding gases produced by a burning propellant, typically gunpowder.
