Abstract: A suspension system for a tracked vehicle including a unitary suspension frame with track wheels mounted thereon for engagement with the lower run of the drive track. Idler means mounted on the rear end of the suspension frame support the rear end of the drive track. Spring means are provided to support the vehicle body on the suspension frame. The spring means are connected such that a predetermined amount of longitudinal relative movement is permitted between the suspension frame and the body. A rearwardly and downwardly sloping control arm is pivotally connected between the body and the front end of the suspension frame so that the forwardly located track wheels are forced downwardly by the control arm when the suspension frame moves forwardly with respect to the body.

Abstract: A low pressure fuel injection system for a two cycle internal combustion engine. Fuel is introduced into the combustion chamber during the intake cycle from a cavity in the wall of the combustion chamber supplied with fuel by metering apparatus that controls the flow of fuel in accordance with engine demand. The fuel is compressibly accumulated when the cavity is covered by the piston during the compression and combustion cycles. As the piston moves into the fuel intake cycle, the cavity is opened and the fuel charge is discharged therefrom and swept out by the flow of intake air for subsequent vaporization and combustion.

Abstract: A suspension system for a tracked vehicle is shown, having a unitary suspension frame including a pair of relatively flexible slide rails for engagement with the lower run of the drive track. Idler means mounted on the rear end of the frame support the rear end of the track. Front and rear pairs of sloping support arms are pivotally connected to the body at their upper ends and are connected to the frame at their lower ends by pivotable link members that accommodate limited relative longitudinal movements between the frame and the body. Front and rear suspension spring means are mounted between the body and the frame. Rearwardly and downwardly sloping control arm means are pivotally connected between the body and the front end portion of the frame so that the pivotal movements thereof force the frame away from the body when the frame moves forwardly with respect to the body, thereby forcing the drive track into tighter engagement with the ground. The front pair of support arms limits the pivotal movements of the control arm means.
