System for injecting fuel e.g. diesel, into combustion chamber of diesel engine, has valve arranged between high pressure injection rail and separating device, and another valve arranged between separating device and fluid pump

摘要

The system (1) has a fuel injector (5) supplying fuel by a high pressure injection rail (2). A separating device (14) is arranged in a line (13) and separates fuel e.g. diesel, and fluid i.e. water, from each other, where the fluid is restored into a fluid container (11) by a return-flow pipe (15). A first valve (16) is arranged between a fluid pump (10) and a mixing device (9), and a second valve (17) is arranged between the high pressure injection rail and separating device, and a third valve (18) is arranged between the separating device and fluid pump. An independent claim is also included for a method for operating an internal combustion engine with a fuel injection system.
