An intake manifold for a compact internal combustion engine includes a pair of arm having air passageways and coolant passageways formed therethrough. The air passageways couple an air inlet at a carburetor flange to respective air outlets at the ends of the arms. The coolant passageways couple coolant inlets at the ends of arms to a coolant chamber having a first and second coolant outlet, the first coolant outlet providing a first coolant path for connecting the coolant chamber to a radiator assembly, and the second coolant outlet providing a second coolant path for connecting the coolant chamber directly to a coolant pump. A thermostatic valve disposed in the coolant chamber directs the engine coolant along the first and second coolant paths as a function of coolant temperature. The manifold further includes an integral radiator support element.

Intake manifold for compact internal combustion engine

A gaseous fuel adaptor for modifying an internal combustion engine having a liquid fuel carburetor. The carburetor has an air intake for receiving air to mix with a liquid fuel. The adaptor includes a body mounted over the carburetor air intake and a passageway having an inlet and an outlet formed in the body. Air enters the passageway through the inlet and air exits the passageway through the outlet into the carburetor air intake. A gaseous fuel feed port disposed between the passageway inlet and outlet feeds gaseous fuel into the passageway, and a butterfly valve disposed in the passageway between the gaseous fuel feed port and the passageway inlet meters air entering the passageway to mix with the gaseous fuel.

Dual fuel system for an internal combustion engine

A dual bore intake manifold for an internal combustion engine is disclosed which has a simplified construction and provides improved engine performance. A one-piece manifold and throttle housing is disclosed resulting in reduced production costs. The one-piece manifold and throttle housing affords easy attachment to an engine as it can be mounted in the same manner as a single bore manifold.
