Abstract
A gaseous fuel management system for an internal combustion engine having a source of gaseous fuel such as LPG or CNG, a throttle control and an exhaust system and having an air intake tube for conducting combustion air into the manifold of the engine and an angularly movable butterfly valve disposed in the air intake tube, responsive to the operation of the throttle control. A fuel delivery bar having an interior longitudinal fuel conducting bore is diametrically disposed in the air intake tube upstream from the butterfly valve and has a plurality of fuel delivery orifices in its downstream facing side which orifices communicate with the interior of the bar. A fuel lane interconnects the interior bore of the fuel delivery bar to the fuel source and an electronically controlled valve meters the amount of fuel admitted to the interior bore of the fuel delivery bar as a function of the oxygen content of the products of combustion in the exhaust system.
