Fuel injecting device for diesel engine of motor vehicle, has insulation unit alternatively stopping flow of one of two parts with other part while maintaining latter part in communication with inlet interface

摘要

The device (1) has a common ramp (4) in which fuel storage volumes (V1, V2) are defined. A fuel inlet interface is emerged from the fuel storage volumes, and is connected to a fuel pump (2). Outlet pipes (51-54) are emerged from the fuel storage volumes and connected to injectors (61-64), respectively. An insulation unit (7) separates the fuel storage volumes into two parts, and alternatively stops flow of the one of the two parts with the other part while maintaining the latter part in communication with the inlet interface. An independent claim is also included for a method for starting an internal combustion engine with a common injection slope.
