";s:4:"text";s:4568:" Batch injection… All components are integrated in a single unit mounted on a multi-position valve. Many diesel engines , however, use direct injection in which the diesel is injected directly into the cylinder filled with compressed air. This ensures that the fuel is well mixed with the air before it enters the chamber. 3. These systems provide more accurate fuel metering and quicker response.
sequential fuel injection is a type of multi-port fuel injection system in which each injection valve will open just. The sequential fuel injection is also known as timed injection and is a multi-port injector. Sequential injection analysis with lab-on-valve was conceived by Ruzicka in 2000 [84] as a progression of the sequential injection system towards downscaling. Sequential fuel injection: lt;p|>||||| | ||||| || This article has multiple issues. The detector compartment is reduced and placed very close to the sample inlet, thus minimising the required volumes of sample, reagent and wash solution. The detector compartment is reduced and placed very close to the sample inlet, thus minimising the required volumes of sample, reagent and wash solution. DI (Direct Injection) is the next evolution of fuel injection where the fuel is injected after the intake valve directly into each cylinder at over 3000 psi. Sequential Fuel Injection. before the cylinder intake valve opens.
The advantage of sequential fuel injection is that if the driver makes a sudden change, the system can respond more quickly because from the time the change is made, it only has to wait only until the next intake valve opens, instead of for the next complete revolution of the engine. All components are integrated in a single unit mounted on a multi-position valve. This ensures that the fuel is well mixed with the air before it enters the chamber. The Sequential Electronic Fuel Injection (SEFI) system is used on all Super High Output (SHO) vehicles, as well as on 1993 and later 3.0L and 3.8L engines. The gasoline fuel injector is an electromagnetic (solenoid-operated) or mechanical device used to direct delivery of or to meter pressurized fuel, or both. Sequential fuel injection synonyms, Sequential fuel injection pronunciation, Sequential fuel injection translation, English dictionary definition of Sequential fuel injection. Sequential injection attempts to only spray fuel while the intake valve is open for the cylinder that is about to fire, which in most cases is only possible at low engine speeds between idle and low speed cruising. The fuel injection system in petrolengined cars is always indirect, petrol being injected into the inlet manifold or inlet port rather than directly into the combustion chambers . Sequential Fuel Injection. The different injectors available in this type of fuel injection works in groups and thus deliver the fuel at the optimized time. In the typical gasoline fuel-injection system, an electric fuel pump provides a specified fuel flow at the required system pressure to one or more fuel-injection valves, or fuel injectors. The fuel injection system in petrolengined cars is always indirect, petrol being injected into the inlet manifold or inlet port rather than directly into the combustion chambers . It is classified as a multi-point, pulse time, speed density control fuel injection system. Sequential injection analysis with lab-on-valve was conceived by Ruzicka in 2000 [84] as a progression of the sequential injection system towards downscaling. Benefits can be seen in emissions, drivability, and fuel economy at these low engine speeds. This can be viewed very similar to the multi-port fuel injection; however, it is a These systems have a fuel injector for each cylinder, usually located so that they spray right at the intake valve. Gradually, as new engines were designed, throttle body fuel injection was replaced by multi-port fuel injection (also known as port, multi-point or sequential fuel injection). The Sequential Electronic Fuel Injection (SEFI) system is used on all Super High Output (SHO) vehicles, as well as on 1993 and later 3.0L and 3.8L engines.
