FUEL SYSTEM FOR INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To feed fuel in various forms. SOLUTION: A common rail 4 connected to an injection valve 2 is selectively connected by either one of a non-mixed fuel rail 6 or a mixed fuel rail 8. Non- mixed fuel comprising liquid fuel not containing a fluid to be mixed is fed into the non-mixed fuel rail 6. Mixed fuel comprising the liquid fuel and the fluid to be mixed in a supercritical state is fed into the mixed fuel rail 8. During normal operation, the mixed fuel rail 8 is connected to the common rail 4 to feed the mixed fuel to an engine 1. During high load or low load, the non-mixed fuel rail 6 is connected to the common rail 4 to feed the non-mixed fuel to the engine 1.
