FUEL SUPPLY SYSTEM FOR MULTI-CYLINDER ENGINE

摘要

In a fuel supply system for a multi-cylinder engine, a pump driving cam is provided between an intake cam and an exhaust cam on a camshaft. The pump driving cam and a fuel pump are interconnected by a pump driving member. The pump driving member is slidably supported on a pair of supporting portion projectingly, integrally provided on a cylinder head and disposed between valve springs of a pair of intake valves. Thus, the intake valves and the valve springs are prevented from interfering with the pump driving member and the supporting portions and therefore, the fuel pump driven by the camshaft in the multi-cylinder engine can be disposed at a lengthwise intermediate portion of the cam shaft. As a result, the distance between the fuel pump and each of carburetors can be decreased to enable a stable supplying of fuel.
