In a manifold injection system, air and fuel are mixed outside the combustion chamber so that a mixture of air and fuel is sucked into the engine. The main types of manifold injections systems are multi-point injection and single-point injection. These systems use either a continuous injection or an intermittent injection design. [16]
The atomisation quality is relative to the injection pressure, which means that a relatively low injection pressure (compared with direct injection) is sufficient for multi-point injected engines. A low injection pressure results in a low relative air-fuel velocity, which causes large, and slowly vapourising fuel droplets. [8]
Programmed Fuel Injection, or PGMFI/PGM-FI, is the name given by Honda to a proprietary digital electronic multi-point injection system for internal combustion engines. It has been available since the early 1980s. This system has been used in motorcycles, automobiles, and outboard motors.
Indirect injection in an internal combustion engine is fuel injection where fuel is not directly injected into the combustion chamber. Gasoline engines equipped with indirect injection systems, wherein a fuel injector delivers the fuel at some point before the intake valve, have mostly fallen out of favor to direct injection. However, certain ...
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.
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).
The 2.4L Theta II Hybrid engine compression ratio is 13.0:1, it features multi-point fuel injection and the gasoline engine produce 171 PS (126 kW; 169 hp) at 6,000 rpm and 21.6 kg⋅m (156 lb⋅ft; 212 N⋅m) of torque at 4,500 rpm, the electric motor is rated 41 PS (30 kW; 40 hp) between 1,400 and 6,000 rpm with 20.9 kg⋅m (151 lb⋅ft; 205 ...
It has a cast iron engine block with Multi-point fuel injection and an aluminum SOHC cylinder head with forged steel connecting rods and four valves per cylinder. The 4G94 Also comes in the GDI DOHC variant which can be found in the Mitsubishi Galant. 4G94 SOHC 16 Valve MPI. Multi-Point Injection (MPI) Total Displacement - 2.0 L (1,999 cc)
