Abstract
An economizer valve for use with an induction and fuel supply system for an internal combustion engine operated on gaseous fuels, for example, LPG or natural gas. The system is used with a conventional mixing valve which supplies air according to engine demand, together with fuel appropriate to the desired charge, and includes a regulator for providing gas to the mixing valve, and an economizer valve responsive to pressure regions upstream from and at and downstream from a throttle valve, effective on the regulator to cause it to lean out the charge under certain conditions and to permit the charge to be enriched at other conditions.
