High pressure fuel holding unit has a hollow metal body to contain the fuel for injection at a diesel motor with a plastics coating on the inner wall to withstand fuel pressure waves

摘要

The high pressure fuel holding unit, for the fuel injection system of an internal combustion motor, has a hollow metal body (1) with connections and/or branches (3) for the fuel (4) inflow and outflow. The inner wall (15) is covered by a plastics coating (2), and especially an elastomer or thermoplastic material or a thermosetting resin. The coating can contain reinforcement glass or carbon fibers.
