ABSTRACT:
In a system in which a common rail accumulates fuel pressurized by a high pressure supply pump, when a pipe connected to the common rail is damaged or a pulsation of fuel injection is caused in the system, reliability of the system is greatly affected because of high pressure. According to the present invention, a mechanism to prevent leakage of fuel from the common rail even when the pipe is damaged, or a mechanism to damp a pulsation of fuel pressure, is provided in a pipe close to the common rail. Therefore, reliability of the system is improved.
