TH32981B - Fuel injection device for motorcycles with main frame. - Google Patents

Abstract

DC60 in a mainframe motorcycle where the main frame protrudes downward behind the body frame and path. ID filed along the main structure. The fuel injection valve is mounted on the upper wall of the intake path without obstruction to the main frame In order to inject fuel into the intake channels on the cylinder head. In a motorcycle with the Ff main body, where the Ff main body extends down behind the F body frame and the intake path 12, which contacts the intake channel 11 on the cylinder head 9, extends along the Ff main body, the fuel injection valve 30 is obtained. Mounting on the top wall of the intake path 12 with at least a top end which provides It is positioned in front of the midpoint 32 on the outer edge of the mid 14c arc of the main frame Ff in mainframe motorcycles where the main frame protrudes downward behind the body frame and path. ID filed along the main structure. The fuel injection valve is mounted on the upper wall of the intake path without obstruction to the main frame In order to inject fuel into the intake channels on the cylinder head. In a motorcycle with the Ff main body, where the Ff main body extends down behind the F body frame and the intake path 12, which contacts the intake channel 11 on the cylinder head 9, extends along the Ff main body, the fuel injection valve 30 is obtained. Mounting on the wall above the intake path12 Along with at least there is a top end which provides It is positioned in front of the center 32 on the outer edge of the arc between the center 14c of the main frame Ff.
