摘要： Methods and systems are described for controlling fuel injection in an engine equipped with a dual injector system including a port injector and a direct injector. A ratio of port injected fuel to direct injected fuel is adjusted based at least on intake valve temperature. The proportion of fuel port injected into a cylinder is increased as the intake valve temperature for the given cylinder increases to improve fuel vaporization in the intake port.

摘要： A fuel supply system supplies composite fuel containing alcohol and gasoline to multiple cylinders of an internal combustion engine. The composite fuel includes main-fuel and sub-fuel. The sub-fuel is lower than main-fuel in concentration of alcohol. Each of multiple first fuel injection valves is provided to each of the cylinders for injecting fuel. Each of multiple second fuel injection valves is provided to each of the cylinders for injecting fuel. A fuel inlet portion supplies at least sub-fuel to each of the first fuel injection valves and each of the second fuel injection valves. A selector control unit selects one of main-fuel and sub-fuel supplied through the fuel inlet portion to each of the first fuel injection valves.

摘要： A fuel injection system for an internal combustion system includes an Engine Management System (EMS), a fuel feed pump, a return line, a high-pressure pump, supplying fuel under pressure to a common rail, a hydraulically operated valve forming an outlet chamber connected to the common rail and a control chamber, the valve being designed such that, in its closed position, the valve prevents the flow out of the outlet chamber, and an electrically operated pilot valve. A nozzle with a resilient member that biases the nozzle towards closing is connected to the outlet of the hydraulically operated valve in such a way that pressure at the outlet of the hydraulically operated valve tends to overcome the force of the resilient member and open the nozzle. An electrically operated spill valve is connected between the outlet of the hydraulically operated valve and the return line.

摘要： A control valve and a fuel injection valve provided with same should be produced, in which it is possible to switch from a first operating state to a second operating state inexpensively and with short switching times, without requiring a hydraulic control line. To this end, a control valve is provided, which has a valve housing, a pressure chamber filled with electrorheological fluid, a displacing element that can slide in the valve housing and protrudes into the pressure chamber, and two electrodes that can apply an electrical field to the electrorheological fluid.

摘要： In a fuel injection system for an internal combustion engine, in which fuel at at least two differently high fuel pressures can be injected via injectors into the combustion chamber of the engine, parallel to a bypass line a hydraulic pressure booster is provided for generating the higher fuel pressure; the pressure booster is actuatable and deactuatable via a valve unit. Since the pressure booster is not constantly in operation, and the losses from friction are also reduced, the efficiency is improved.

摘要： A common-rail injection system includes a first accumulator of high pressure and a second accumulator of low pressure. The common-rail injection system includes a post injection control device for injecting additional low-pressure fuel from the second accumulator through a fuel injection nozzle after main fuel is injected. The post injection control device injects the additional fuel the injection terminates at a first timing when the fuel pressure in either fuel passage or second accumulator lowers to a predetermined value lower than that of the high-pressure fuel or at a second timing when an exhaust stroke of the engine is completed, whichever earlier.
