ABSTRACT:
A slow-run system for gaseous fueled internal combustion engines, including gaseous fuel conversions of liquid fuel engines for alternate operation on either fuel, employs a valve having an inlet receiving gaseous fuel from between the primary regulator and zero pressure governor and an outlet emptying into the air cleaner assembly upstream of the liquid fuel carburetor or equivalent means. The valve is actuated through a connection into the engine air intake manifold or similar passage below the throttle such that the valve opens to supply gaseous fuel to the air cleaner assembly during slow-run when manifold vacuum is high and remains open throughout substantially all of the engine's operating range.
