Flywheel Overbalance
US Patent:
4262548, Apr 21, 1981
Filed:
May 7, 1979
Appl. No.:
6/036761
Inventors:
Gerald Haft - Brookfield WI
Otto H. Scharpf - Brookfield WI
Otto H. Scharpf - Brookfield WI
Assignee:
Outboard Marine Corporation - Waukegan IL
International Classification:
F16H 2122
F02B 7506
F02B 7506
US Classification:
74 44
Abstract:
A powered device has a center of gravity and includes an engine comprising a block member, a crankshaft having opposite first and second end portions, and generally spaced supports on the block member for supporting the crankshaft for rotation with the first end portion extending toward the center of gravity and the second end portion extending beyond the supports. A piston is located in the block member for reciprocative movement, and a connecting rod has a first end portion pivotally connected with the piston and a rotationally balanced second end portion rotationally connected with the crankshaft intermediate the supports for converting the reciprocative movement of the piston into rotation of the crankshaft about its axis. The engine includes a counterweight on the crankshaft adjacent to the second end portion of the crankshaft for generating an offsetting foce during piston reciprocation to reduce vibration axially along the reciprocative axis of the piston and rotationally about an axis which extends through the center of gravity of the device.
Outboard Motor Including Folded Tuned Exhaust Gas Passage
US Patent:
4337054, Jun 29, 1982
Filed:
Mar 17, 1980
Appl. No.:
6/131117
Inventors:
Theodore J. Holtermann - Milwaukee WI
Otto H. Scharpf - Brookfield WI
Otto H. Scharpf - Brookfield WI
Assignee:
Outboard Marine Corporation - Waukegan IL
International Classification:
B63H 2126
US Classification:
440 89
Abstract:
The invention includes an outboard motor comprising a power head having an exhaust gas port, a drive shaft housing extending downwardly from the power head and including an exhaust gas discharge outlet adjacent its lower end, and a continuous folded passage housed in the drive shaft housing. The folded passage includes a first passage portion having an upper end communicating with the exhaust gas port a second portion extending upwardly from the lower end of the first portion and having an upper end, and a third portion communicating with the upper end of the second portion. The folded passage functions to return to the exhaust port as positive pressure pulses the pressure pulses emitted by the exhaust ports, the folded passage causing return of the pressure pulses in timed relation with respect to closing of the exhaust port to thereby facilitate precompression of the fuel mixture entering the cylinder.
Two-Cycle Internal Combustion Engine Having High Swirl Combustion Chamber
US Patent:
4359027, Nov 16, 1982
Filed:
Sep 22, 1980
Appl. No.:
6/189010
Inventors:
Otto H. Scharpf - Brookfield WI
Assignee:
Outboard Marine Corporation - Waukegan IL
International Classification:
F02B 2308
US Classification:
123307
Abstract:
Disclosed is a two-cycle, internal combustion engine including an engine block, and a cylinder in the engine block having a head and generally opposed inlet and outlet walls respectively including at least one intake port through which a fresh charge is admitted into the cylinder and at least one outlet port through which exhaust gases are exhausted from the cylinder. A piston is mounted for reciprocative movement inside the cylinder between a first position spaced from the cylinder head wherein the intake port is uncovered, a top dead center position, and a third position wherein the piston approaches the top dead center position. The piston has a top, an inlet face portion which periodically covers and uncovers the intake port and an outlet face portion which periodically covers and uncovers the outlet port. The piston and cylinder have a configuration causing increased swirling of the fresh charge in the cylinder as the piston moves from the third position to the top dead center position. The piston and cylinder are constructed so as to form two spaced apart chambers in the cylinder when the piston is in the third position and for causing that portion of the charge in one of the chambers to be forced into the other of the chambers as the piston moves to the top dead center position.
Exhaust System With Side Branch
US Patent:
4660378, Apr 28, 1987
Filed:
Dec 21, 1984
Appl. No.:
6/685238
Inventors:
Otto H. Scharpf - Brookfield WI
Assignee:
Outboard Marine Corporation - Waukegan IL
International Classification:
F02B 2702
US Classification:
60313
Abstract:
An engine apparatus comprising an internal combustion engine having a cylinder with an exhaust port, an exhaust gas passageway system communicating with the exhaust port for providing a first compressive wave arriving at the exhaust port prior to closure thereof, and an exhaust gas side branch for providing a second compressive wave arriving at the exhaust port after the first compressive wave and prior to closure of the exhaust port.
