Apparatus and method for removal of oil or other waste liquid material from an oil filter untit associated with an internal combustion engine and production of any ecologically stable waste oil filter unit

摘要

A method and apparatus for removing spent oil from an internal combustion engine (12) and evacuating oil retained in an associated oil filter or filters (16) which includes the steps of connecting an external, separable apparatus (10) to the internal oil lubrication distribution system at a first point (48) upstream of the oil filter, and at a second point (46) in fluid communication with the oil reservoir; introducing a volume of purge gas in a manner sufficient to evacuate retained spent oil to the oil reservoir; and removing spent oil from the oil reservoir and measuring the amount removed. At least one pulse of pressurized purge gas may be introduced.
