Engine Revision for Peristaltic Oil Change

摘要

A method and a kit for oil removal or injection into the oil pan of a vehicle, marine or aircraft engine. A modified dip stick tube extends to the bottom of the oil pan has at least one or more openings at its bottom end to allow oil to enter or exit. The top has an air-tight seal that can be attached to a flexible tube that can be run to a peristaltic pump. The pump can have an exit tube that runs into an oil recovery receptacle. After draining, the oil, the tube can be valved or physically relocated to a fresh oil source. The direction of rotation of the pump can be reversed to fill the oil pan with fresh oil. An electric control can run the pump in both a forward and reverse direction typically from a vehicle battery voltage source.

主权项

1. A method of facilitating removal or addition of oil for a boat or vehicle engine having an oil pan comprising:
modifying an existing vehicle dip stick tube to have an air-tight seal at a proximal end and to extend to the bottom of the oil pan, and to have at least one hole at a distal end, or providing to the vehicle a dip stick tube having an air-tight seal at a proximal end that extends to the bottom of the oil pan and at least one opening at a distal end; providing at least: a peristaltic pump adapted to receive and pass through a flexible tube, the flexible tube adapted to mate with the air-tight seal on the dip stick tube at a first end, pass through the peristaltic pump, and run to an oil recovery receptacle at a second end; providing a peristaltic pump motor mechanically coupled to the peristaltic pump adapted to rotate the peristaltic pump; providing an electric control adapted to allow the peristaltic pump motor to be powered from a voltage source; instructing a user to run the flexible tube through the peristaltic pump; instructing the user to attach the first end of the flexible tube to the dip stick tube; instructing the user to run the second end of the flexible tube into the oil recovery receptacle; instructing the user to power the peristaltic pump from the voltage source through the control unit to pump oil from the oil pan into the recovery receptacle.
