Liquid Fuel System Method And Apparatus
US Patent:
4651682, Mar 24, 1987
Filed:
Mar 12, 1985
Appl. No.:
6/711086
Inventors:
Richard K. Pefley - Santa Clara CA
James B. Pullman - Santa Clara CA
James B. Pullman - Santa Clara CA
Assignee:
Prodatek Corporation - Sunnyvale CA
International Classification:
F02B 7512
US Classification:
123 1A
Abstract:
A system is described for improving performance of spark ignition, internal combustion engines using fuels such as liquified petroleum gas (LP-gas), which have conventionally been stored as a liquid and delivered to the engine as a vapor. This system stores such fuels as liquids (10) and delivers the fuel to the engine inlet air stream as a liquid. The absorption of heat by the vaporizing fuel lowers engine inlet air temperature, increasing its density and permitting more fuel to be burned in each cycle. Vaporizing heat in a pilot line (17) provides the cooling to the liquid fuel in the main fuel line (20) and provides fuel to maintain the engine idling. A member (27) slides within a fuel delivery chamber (25) for covering or uncovering a series of orifices (26) through which the liquid fuel passes into the inlet air stream of the engine.
Refrigerated Filter Assembly And Method Of Using Same
US Patent:
4466257, Aug 21, 1984
Filed:
Aug 17, 1982
Appl. No.:
6/408911
Inventors:
Richard K. Pefley - Santa Clara CA
J. Barrett Pullman - Santa Clara CA
J. Barrett Pullman - Santa Clara CA
Assignee:
Prodatek Corporation - Portola Valley CA
International Classification:
F25D 302
US Classification:
62318
Abstract:
The present invention is a self-aided refrigerated filter assembly and method for its use for filtration of liquid petroleum gas (LPG) so that a liquid phase is maintained during the filtration process and that the LPG is sufficiently subcooled to suppress the formation bubbles to prevent the risk of vapor lock or cavitation damages to a pump downflow from the filtration process and/or to provide liquid for metering purpose.
