Leakage point diagnosis component for engine fuel system has leakage collection cavity in connecting block connected to each leakage path; leakage diagnosis connection in block extends between each cavity and outer surface of block

摘要

The device (50) has a connection block with inlets and at least one outlet opening at an external surface of the block. The inlets are connected to the at least one outlet via leakage paths arranged in the block. A leakage collection cavity in the block is connected to each leakage path and a leakage diagnosis connection in the block extends between each cavity and the outer surface of the block. Independent claims are also included for the following: (A) a fuel system with high-pressure fuel chambers, leakage lines and a leakage diagnosis connection (B) and a method of diagnosing leakage points in a fuel system for an engine.
