Abstract
One embodiment of a method for operating an internal combustion engine under a pressure less than atmospheric pressure includes the steps of positioning a vacuum pump such that said vacuum pump is in fluid communication with a crankcase of said internal combustion engine, connecting a discharge of said vacuum pump to a separator, wherein a portion of said discharge of said vacuum pump condenses in said separator, connecting a vapor discharge of said separator to a filter, wherein said filter removes a portion of volatile organic compounds from said vapor discharge, and venting said filter to an ambient atmosphere.
Claims5
A method of operating an internal combustion engine under a pressure less than atmospheric pressure, said method comprising the steps of:
- a. positioning a vacuum pump such that said vacuum pump is in fluid communication with a crankcase of said internal combustion engine, wherein said vacuum pump is further defined as subjecting said crankcase to a pressure that is less than an atmosphere pressure, and wherein said vacuum pump is further defined as subjecting said crankcase to a pressure that is between 0.5 and 8.5 inches of water less than an atmosphere pressure and a pressure differential, of the vacuum pump, is dictated by a rate of speed at which said internal combustion engine is turning;
- b. connecting a discharge of said vacuum pump to a separator, wherein a portion of said discharge of said vacuum pump condenses in said separator;
- c. connecting a vapor discharge of said separator to a filter, wherein said filter removes a portion of volatile organic compounds from said vapor discharge;
- and,
- d. venting said filter to an ambient atmosphere.
