Patent number: 4924819Abstract: A rotary exhaust control valve for two-stroke cycle engines is disclosed. This valve is oriented at least partially within the exhaust passage and, for each revolution of the engine, delays flow from the combustion chamber through the exhaust passage during the expansion stroke of the piston while permitting full opening of the exhaust passage and blow down to initiate the scavenging cycle of the engine. The valve of the present invention permits complete opening and closing of the exhaust passage during the appropriate portions of the engine cycle. Also disclosed is a mechanical linkage mechanism between the rotary valve and the crankshaft to provide precise control of the exhaust valve throughout the engine cycle.Type: GrantFiled: May 15, 1989Date of Patent: May 15, 1990Assignee: Performance Industries, Inc.Inventor: Eyvind Boyesen

Patent number: 4909193Abstract: An exhaust control valve for two-stroke cycle engines used in conjunction with a fuel injection system is disclosed. This valve is within the exhaust passage and, for each revolution of the engine, delays opening of the exhaust passage to the combustion chamber during the expansion stroke of the piston for a preselected number of degrees of rotation of the crankshaft while permitting the necessary opening of the exhaust port to give complete blow down before the scavenging cycle. The valve also permits advanced closing of the exhaust port to eliminate short circuiting of the fresh charge out the exhaust port. A fuel injection system, providing fuel either upstream or downstream from valves in the engine's air intake passage, is provided to operate in timed relation to the piston strokes and the exhaust valve. Also disclosed are means for modifying opening of the exhaust valve at high engine speeds to improve scavenging.Type: GrantFiled: May 15, 1989Date of Patent: March 20, 1990Assignee: Performance Industries, Inc.Inventor: Eyvind Boyesen

Patent number: RE40481Abstract: Filtration method and device for filtering solid contaminants from a stream of a flowing fluid such as internal combustion engine intake air. An imperforate housing has a tubular inlet exiting at its downstream end into a conically divergent first wall section terminating in a maximum diameter apex. A convergent second wall section terminates at a housing outlet opening of greater diameter than that of the housing inlet. A perforate filter element disposed within the housing conical portions has an exterior configuration generally complimental to the housing interior, and thus has a first generally conical divergent section, and a second generally conical downstream section convergent from a maximum diameter apex of the filter element and defining the filter device outlet.
