Abstract
A remote drain and filter arrangement for a portable engine-driven generator is disclosed that positions the oil filter and oil drain at a location outside the enclosure of the generator. The arrangement generally consists of an oil filter assembly and oil drain assembly. The oil filter assembly includes an oil filter adapter used to interface with the oil filter and is coupled to the engine via oil conduits. The oil drain assembly includes an oil drain conduit and a flow control device that allows the oil to be drained from a location outside of the enclosure of the generator. A pump can be used to allow for sufficiently longer oil conduits. The invention is retrofittable to current engine-driven generators and can also be incorporated into future designs.
