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 certain areas within the cylinder to optimize combustion.
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 ...
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).
common-rail Fuel Stratified Injection (FSI) high-pressure direct injection between 30 and 100 bar (435 and 1,450 psi) aspiration & exhaust system variable intake manifold, two ceramic catalytic converters dimensions length: 360 mm (14.2 in), width: 430 mm (16.9 in), mass: 169.5 kg (374 lb) DIN-rated motive power & torque outputs
In a continuous injection system, fuel flows at all times from the fuel injectors, but at a variable flow rate. The most common automotive continuous injection system is the Bosch K-Jetronic system, introduced in 1974 and used until the mid-1990s by various car manufacturers.
It features some of the latest engine technology such as direct fuel injection, sintered camshaft lobes, thin-walled engine block, variable valve timing and lift for intake and exhaust valves, downstream oxygen sensors, exhaust manifold integrated into the cylinder head, exhaust gas recirculation and cooling, distributors coil-on-plug ignition ...
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.
Specifically, it is an all-aluminium alloy 32-valve (four valves per cylinder) petrol engine, [12] utilising Fuel Stratified Injection (FSI), [12] and has a displacement of 4,163 cc (4.2 L). [12] It develops a motive power output of 420 PS (309 kW; 414 hp) ( Directive 80/1269/EEC ) , [ 12 ] and generates 430 N⋅m (317 lbf⋅ft) of torque, [ 12 ...
