ABSTRACT:
Several embodiments of additional fuel supply systems for internal combustion engines that supply supplemental fuel in addition to the normal charge forming device to satisfy certain specific requirements such as cold starting and cold running. In each embodiment, a separate fuel pump is provided for the supplemental fuel discharge but it is contained within and operated by the same operator of the main fuel pump for supplying fuel to the main fuel discharge. In some embodiments, the fuel pump is downstream of the supplemental fuel control and in other embodiments it is upstream of it. In one embodiment, the fuel pump and the supplemental control are all formed in the same housing.
