Engine flushing apparatus

An engine flushing system for flushing an engine having an oil circulation system including an oil fill opening at an upper location on the engine and an oil drain opening on a lower location on the engine, the engine flushing system comprising:

• a solution tank for holding a solution, the solution tank having an upper opening and a substantially hollow interior, the solution tank having a bottom, a suction conduit extending into the interior of the solution tank from the opening toward the bottom thereof, a bypass conduit extending through the opening toward the bottom of the solution tank, wherein the solution comprises a solvent, wherein the solution comprises kerosene;
• a waste solution tank for holding waste solution, the waste solution tank having an upper opening and a substantially hollow interior, the waste solution tank having a bottom, a drain conduit extending into the interior of the waste solution tank from the opening toward the bottom thereof, wherein the waste solution comprises a solution that has been circulated through the engine;
• a pump for circulating solution, the pump being in fluid communication with the suction conduit of the solution tank, a valve being fluidly interposed between the pump and the suction conduit, the pump being in fluid communication with the drain conduit of the waste solution tank, a valve being fluidly interposed between the pump and the drain conduit;
• an inlet conduit for carrying solution to the engine, the inlet conduit being adapted for connection to the oil fill opening of the engine, the inlet conduit having a first end and a second end, the first end being connected to the pump and the second end being connectable to the oil fill opening of the engine, a valve being fluidly interposed between the pump and the inlet conduit, an inlet adapter for connecting to the oil fill opening of the engine, the inlet adapter being mounted on the second end of the inlet conduit, the inlet adapter having a cap with a aperture therethrough, the cap having a structure similar to a closure cap for closing the oil fill opening of the engine, a valve in fluid communication with the inlet conduit for selectively blocking flow of solution through the inlet conduit, the valve being located near the second end of the inlet conduit;
• an outlet conduit for carrying solution away from the engine, the outlet conduit being adapted for connection to the oil drain opening of the engine, the outlet conduit having a first end and a second end, the first end being connected to the pump and the second end being connectable to the oil drain opening of the engine, a valve being fluidly interposed between the pump and the outlet conduit, an outlet adapter for connecting to the oil drain opening of the engine, the outlet adapter being mounted to the second end of the outlet conduit, the outlet adapter comprising a nipple portion for inserting into the oil drain opening of the engine, the nipple portion having a threaded exterior surface for threading into the oil drain opening, a nut being threaded on the nipple portion for locking the outlet adapter in the oil drain opening, the nipple portion having a first passage therethrough, the first passage having a shoulder formed therein, a ball being positioned adjacent to the shoulder and having a diameter permitting the ball to close the first passage when the ball is abutted against the shoulder, a threaded member positioned in the first passage for selectively abutting the ball against the shoulder, the threaded member having a threaded exterior surface for engaging threads on the interior surface of the first passage such that the threaded member may be advanced and retracted by rotation of the threaded member, the threaded member having a hex head thereon for permitting a wrench to engage the threaded member, a connector portion mounted to the nipple portion and having a second passage in fluid communication with the first passage, the connector portion having an opening in communication with the second passage, an exterior surface of the connector portion having an annular groove, a coupler on the second end of the outlet conduit being removably couplable to the connector portion of the outlet adapter;
• a transport cart, the transport cart having a base with an upper surface for resting the solution and drain tanks, a pump support being mounted on the transport cart, the pump support extending upward from the base, the pump support comprising:
• an upstanding member mounted on the base,
• a support mounted on an upper end of the upstanding member, the support having an upper surface for resting the pump thereon,
• a plurality of brace members extending from the upstanding member and the base,
• a plurality of wheels mounted on the base;
• wherein the solution tank and the waste solution tank are rested on the upper surface of the base and being adapted for permitting lifting removal from the base for filling or emptying the tanks;
• a washer tray having a bottom wall and a perimeter wall extending substantially perpendicularly to a perimeter of the bottom wall, the washer tray having a solution return fitting extending through the perimeter wall and having a portion extending adjacent to the bottom wall for suctioning solution from the bottom of the washer tray.
