Abstract
A fuel management system for blending of an alternative fuel such as waste oil with a conventional fuel and the continuous filtration thereof before delivery to fuel injection system of a conventional diesel engine. The system attaches to the storage tanks of a heavy duty truck using a proportioning device for withdrawing of the fuels from their respective tanks before blending by use of an air operated diaphragm transfer pump. The blended fuel is continuously recirculated through at least one fiberglass filter with a device for metering the final flow to the injection system and the remainder to the storage tanks. The system can remove up to 99.5 percent of the heavy contaminants found in the diesel fuel and alternative fuels.
