摘要： With a cylinder direct injection engine in which fuel is injected directly into combustion chambers and air-fuel mixture is guided by an air flow, it is difficult to secure combustion stability under low engine speed and low load conditions such as during idling. Furthermore, there are needs for improvement of emission characteristics and fuel economy in other operation modes as well. An engine according to the invention injects fuel while dividing the same in plural parts during a compression stroke. The first injection forms a lean air-fuel mixture around an ignition plug, and the second injection makes a flammable air-fuel mixture reach an area around the ignition plug. This ensures efficient stratified combustion and allows improvement in emission and fuel economy performance.

摘要： A control unit is used for controlling a direct fuel injection type internal combustion engine. The control unit controls a fuel injection valve to have a first fuel injection mode wherein a penetration force of an injected fuel sharply increases at an initial stage of a fuel injection and thereafter an increasing rate of the penetration force gradually lowers with passage of time and a second fuel injection mode wherein the penetration force of the injected fuel sharply increases at a middle stage of the fuel injection. The control unit further controls the fuel injection valve in a manner to switch the first and second fuel injection modes in accordance with an operation condition of the engine.

The nozzle hole plate is disposed at a downstream side of a fuel passage of the valve seat. The nozzle hole plate has a nozzle hole for injecting fuel flowing out from the fuel passage. The valve member seats on the valve seat to close the fuel passage and unseats from the valve seat to open the fuel passage. Diameter of the inner circumferential surface decreases as approaching to a downstream side. The nozzle hole of the nozzle hole plate is formed so that length of radial outside of the nozzle hole with respect to a shaft center of the fuel injection valve is smaller than that of radial inside of the nozzle hole.

摘要： A fuel injector that allows spray targeting and distribution of fuel to be configured using non-angled or straight orifice having an axis parallel to a longitudinal axis of a valve subassembly. Metering orifices are located about the longitudinal axis and defining a first virtual circle greater than a second virtual circle defined by a projection of the sealing surface onto the metering disc so that all of the metering orifices are disposed outside the second virtual circle. The projection of the sealing surface converges at a virtual apex disposed within the metering disc. At least one channel extends between a first end and second end. The first end is disposed at a first radius from the longitudinal axis and spaced at a first distance from the metering disc. The second end is disposed at a second radius with respect to the longitudinal axis and spaced at a second distance from the metering disc such that a product of the first radius and the first distance is approximately equal to a product of the second radius and the second distance. Methods of controlling spray distribution and targeting are also provided.
