摘要： An injection unit (9) for injection of a first fuel (f1) and a second fuel (f2) in a combustion space. The injection unit (9) receives the first fuel (f1) from a fuel source (7) at a high pressure, and a second fuel (f2) from a second fuel source (15) at a lower pressure, an actuator (29) initiates a process of injecting at least the second fuel (f2) in the combustion space, and an injection nozzle (36) injects at least the second fuel (f2) in the combustion space. The injection unit includes a pressure boosting device (40) for increasing the pressure of the second fuel (f2) higher than the pressure in the second fuel source (15) by means of the pressure of the first fuel (f1), before the second fuel is injected.

摘要： Fuel injectors with intensified fuel storage and methods of operating an engine therewith. At least one storage cavity is provided in the intensifier type fuel injector, with a check valve between the intensifier and the needle chamber and storage cavity preventing loss of injection pressure while the intensifier plunger cylinder is refilling with fuel. This provides very efficient injector operation, particularly at low engine loads, by eliminating the wasted energy of compressing, venting and recompressing fuel for injection. Various injector designs and methods of operating the same in an engine are disclosed.

摘要： An apparatus for injecting fuel into an internal combustion engine having a fuel injector acted on with highly pressurized fuel actuated by means of a metering valve device that is able to control the pressure in a pressure booster control chamber so that in a pressure booster pressure chamber delimited by a pressure booster piston which can be filled via a check valve with high-pressure fuel and communicates with an injection valve member pressure chamber, the pressure booster piston increases the pressure, causing an injection valve member for injecting fuel to open. To assure a correct injection quantity even if an abrupt pressure drop occurs in the high-pressure fuel source, the pressure booster piston is situated and designed so that if a pressure drop occurs in the high-pressure fuel source, then starting from its neutral position, the pressure booster piston has the capacity to execute a pressure compensation movement by means of which the pressure in the pressure booster pressure chamber is adapted to the pressure of the high-pressure fuel source.

摘要： The present invention provides a simplified fuel injector which uses fuel as hydraulic oil to intensify the injection pressure.A pressure intensifier of the fuel injector is provided with a pressurization piston 106, a first fuel chamber 107 that communicates with a fuel inlet passage 101 (or a fuel supply passage), and a fuel pressurization chamber 111. The pressurization chamber 111 is provided inside a valve body 110. The pressurization piston 106 is formed displaceably relative to the valve body 110 and is provided with a first pressure receiving surface 106a and a pressurization piston portion 106b. The first pressure receiving surface 106a is one end surface of the pressurization piston 106 which faces one of the piston displacement directions 106d, that is, faces the first fuel chamber 107. The pressurization piston portion 106b is provided on the other end surface of the piston 106 which faces the other direction of the piston displacement directions 106d, that is, faces the pressurization chamber 111. The area of the pressurization piston portion 106b which faces the pressurization chamber 111 is smaller than that of the first pressure receiving surface 106a, and the pressurization piston portion 106b serves to change the volume of the pressurization chamber 111.

摘要： A fuel injector for injecting fuel into a combustion chamber of an internal combustion engine, including a pressure booster, whose booster piston separates a work chamber, subjected to fuel via a pressure reservoir, from a pressure-relievable differential pressure chamber. A pressure change in the differential pressure chamber is effected via an actuation of a servo valve, which opens or closes a hydraulic connection of the differential pressure chamber to a first low-pressure-side return. The servo valve has a piston guided between a control chamber and a first hydraulic chamber. On this servo valve piston, a hydraulic face that positions the servo valve piston constantly in the opening direction when system pressure is applied and a first sealing seat that closes or opens a low-pressure-side return are embodied.
