| 摘要 |
The invention is in a regulator and converter operated to fumigate a volatile material, preferably a liquified petroleum gas (LPG), under vacuum, into an intake air flow of an internal combustion diesel engine to provide, on demand generated by an operator closing a throttle, passage of LPG to the regulator and converter wherein it is vaporized and the LPG vapors are passed into the engine intake air flow that travels into the engine. The injection of LPG vapors provides for an increase in engine output power and an improvement in fuel percentage of burn. The regulator and converter is connected the engine coolant system to receive a hot coolant flow, heating an LPG flow path therethrough to vaporize the LPG with the LPG vapors then directed from the regulator and converter into the engine intake air flow. With the control of LPG passage to the regulator and converter controlled by operation of an LPG cutoff valve that is operated responsive to a presence of a system as sense by high and/or low pressure switches.
