FUEL SUPPLY SYSTEM FOR FOUR-CYCLE ENGINE FOR OUTBOARD MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a fuel supply system for a four-cycle engine for an outboard motor having high degree of freedom on the arranging position of a high-pressure fuel pump and capable of miniaturizing an outboard motor by reducing a necessary arranging space. SOLUTION: This fuel supply system is used for a four-cycle engine for an outboard motor mounted on a hull by directing a crankshaft 8 in the longitudinal direction. A vapor separator tank 25 and the high-pressure pump 21 for fuel injection are so disposed as to establish a height relationship allowing the fuel in the vapor separator tank 25 to be fed to the high-pressure fuel pump by gravitation.
