A common rail fuel injection system in which the pressure in the return line is controlled as a function of the delivery pressure of the presupply pump. This improves the operating behavior of a high-pressure fuel pump and the injectors which are supplied with fuel by means of a common ...
I would like opinions of where the return fuel line from my injection set up should go, either the fuel tank or collector pot. I have a 35 litre fuel tank with a 3 litre internal collector. There are 2 low pressure pumps feeding the high pressure unit in the collector. If I put the...

The pressure regulator maintains the correct fuel pressure by allowing unneeded fuel to return to the fuel tank through a fuel return line. The return line must be unrestricted to prevent excess fuel system pressure. 压力调节器维持正确的燃油压力,允许多余的燃油通过燃油回流管返回油箱来实现。 回流...
The invention relates to a fuel injection device with a multi-part injector body containing a pressure booster that can be actuated by means of a differential pressure chamber, and includes a pressure booster piston that seals a working chamber off from the differential pressure chamber. An on-of...
The unit has a control valve (5) to increase and reduce the pressure in the control chamber (4), whereby the jet needle (12) is opened if the pressure in the control chamber drops. The fuel injection unit additionally has a control section in order to control the lift position of the ...
