Abstract
During servicing, used lubricating oil is pumped (7) from the sump of a compression ignition engine (4) crankcase to a reservoir means (8), then filtered (10) and mixed (2) with fuel oil returning (12) to a supply tank (14). The filtered (10) used lubricating oil is effectively mixed (2) with the fuel (12) for burning in the engine (4).
Claims4
A system for addition of used lubricating oil to fuel oil to be burned by a compression ignition engine, said system comprising:
- a disconnect means releasibly connected to the compression ignition engine and having an outlet;
- a pump having an inlet for receiving used lubricating oil from the disconnect means and having an outlet;
- a reservoir having an inlet for receiving from the pump used lubricating oil and having a valved outlet;
- filter means having an inlet for receiving from the reservoir used lubricating oil and having an outlet;
- mixing means for receiving the used, filtered lubricating oil from the filter means and excess fuel oil and having an inlet and an outlet, said mixing means including:
- a first conduit reducer;
- a second conduit reducer fitting inside the first conduit reducer;
- a ball bearing resting in the neck of said first conduit reducer;
- a conduit cap covering the ball bearing and allowing the ball bearing adequate movement for dispensing the lubricating oil into the mixing means;
- and
- a nipple attaching the tint conduit reducer to a tee, wherein the tee is used to allow the excess fuel oil into the mixer means and to further allow the mixture of fuel oil and lubricating oil to enter into the engine fuel tank;
- and
- a fuel tank having an inlet connected to the mixing means.
A system for addition of used lubricating oil to fuel oil to be burned by a compression ignition engine, said system comprising:
- a disconnect means releasibly connected to the compression ignition diesel engine and having an outlet;
- a pump having an inlet for receiving used lubricating oil and an outlet;
- a reservoir having an inlet for receiving used lubricating oil and a valved outlet;
- filter means having an inlet for receiving used lubricating oil and an outlet;
- mixing means for receiving the used, filtered lubricating oil and excess fuel oil having an inlet and an outlet;
- a fuel tank having an inlet;
- first conduit means extending from the outlet of the disconnect means to the inlet of the pump;
- second conduit means extending from the outlet of the pump to the inlet of the reservoir;
- third conduit means extending from the valved outlet of the reservoir to the inlet of the filter means;
- fourth conduit means extending from the outlet of the filter means to the inlet of the mixing means;
- and
- fifth conduit means extending from the outlet of the mixing means to the inlet of a fuel oil tank.
A system for addition of used lubricating oil to fuel oil to be burned by a compression ignition engine, said system comprising:
- means for extracting used lubricating oil from the compression ignition engine;
- means for receiving and storing the extracted lubricating oil for further processing;
- means for filtering the extracted lubricating oil;
- means for mixing the filtered lubricating oil with fuel oil wherein the mixing means includes a first and second conduit reducer, a ball bearing, a conduit cap, a nipple and a tee;
- and
- means for adding the mixture of filtered lubricating oil and fuel oil to a fuel tank.
