Abstract
An engine choke actuation system automatically controls both the opening degree of the choke and throttle valves of a plurality of charge formers during all phases of engine warmup. The engine choke actuation system also includes a manual override mechanism which allows the associated choke valves to be opened manually in case of a system malfunction.
Claims14
An engine choke actuation system for use with a plurality of choke devices comprising a linkage which interconnects said choke devices so as to operate said choke devices generally in unison, said linkage comprising a plurality of interconnected linkage rods each of which connects to at least one of said choke devices to operate said choke devices between a closed position and an open position, an end of at least one of said linkage rods being readily detachable from the corresponding choke device, and a hook positioned near said detachable end of the linkage rod and configured to receive said detachable end of said linkage rod, the corresponding choke device being positioned in said open position with said detachable end inserted into said hook.
An engine choke actuation system for use with a plurality of choke devices comprising a linkage which interconnects said choke devices so as to operate said choke devices generally in unison, said linkage comprising a plurality of interconnected linkage rods each of which connects to at least one of said choke devices to operate said choke devices between a closed position and an open position, means for manually operating said linkage to open at least a majority of said choke devices, a bracket interconnecting said choke devices together, and a hook being formed on said bracket to engage one of said linkage rods and hold it in a position to open at least one choke valve, wherein said plurality of choke devices are aligned above one another in a generally vertical orientation, and said means for manually operating said linkage operates in connection with an uppermost choke device of said plurality of said choke devices.
A method for manually operating an engine choke actuation system comprising a linkage interconnecting a plurality of choke devices, said linkage comprising a plurality of choke levers interconnected by linkage rods, said choke levers operating choke shafts of the choke devices to operate said choke devices between an open and closed is position, said method comprising the steps of disconnecting one end of one of a linkage rod of said linkage from a choke lever of said linkage, moving the disconnected end to a position near a hook of the engine choke actuation system to open at least some of said choke devices, and engaging the disconnected end with said hook.
