摘要： A fuel injection system for automotive diesel engine is provided which is equipped with a fuel pressure sensor working to measure the pressure of fuel in an accumulator and a pressure-reducing valve working to drain the fuel from the accumulator. The system is designed to ensure enhanced reliability of diagnosis of the pressure-reducing valve. The system works to make a temporal diagnosis of the pressure-reducing valve based on the behavior of the pressure in the accumulator upon opening of the pressure-reducing valve after an ignition switch is turned off. After elapse of a given period of time, when it is determined that a value of the pressure in the accumulator, as measured by the fuel pressure sensor, lies near the atmospheric pressure, the system determines that the fuel pressure sensor is operating properly and fixes the temporal diagnosis of the pressure-reducing valve ultimately.

摘要： The present invention provides a fuel supply system which can supply fuel accurately in accordance with driving conditions, while achieving cost reduction by adopting an inexpensive pump without a fuel return passage for returning surplus fuel. A positive displacement pump which intakes and discharges a specific volume of fluid is adopted as the fuel pump 40, and discharges the amount of fuel needed for the injector 30 to inject. The fuel pump 40 is located outside the vapor separator 20. The discharged fuel from the fuel pump 40 is supplied to the injector 30 through the returnless pressure regulator 50. With this structure, the temperature rising of the fuel in the vapor separator 20 due to disposing the high pressure fuel pump and the pressure regulator within the vapor separator 20 can be prevented, and the connecting passage for connecting the pressure regulator and the vapor separator can be eliminated.
摘要翻译：本发明提供一种燃料供给系统，其可以根据驾驶条件准确地供给燃料，同时通过采用廉价的泵，而不需要用于返回多余燃料的燃料返回通道来实现成本降低。作为燃料泵40，采用吸入和排出特定体积流体的容积式泵，并排出喷射器30所需的燃料量。燃料泵40位于蒸汽分离器20的外部。来自燃料泵40的排出的燃料通过无返回压力调节器50被供给到喷射器30。利用这种结构，可以防止由于在蒸气分离器20内设置高压燃料泵和压力调节器而使蒸气分离器20中的燃料升温，并且用于连接压力调节器和蒸气分离器的连接通道可以被淘汰。

摘要： A precision fuel rail assembly for direct fuel injection comprising a plurality of formed parts first assembled and positioned loosely on a precision fixture, then joined (e.g. tack welded), by applying a BFM on all joints forming a “green” assembly and firing in a brazing oven, to produce a precision assembly formed from stainless steel parts. A bracket defining a sole plate for the assembly may be formed as a continuous element or a plurality of individual fuel rail brackets. Flanged sockets are attached to the bracket at locations corresponding to the fuel injector locations on an engine bank. Bolt holes are provided along the centerline of the sockets and fuel injectors. The bracket supports a fuel distribution tube via saddle elements disposed between the bracket and the tube. A jump tube supplies fuel from the distribution tube to each socket.
