20090293462 | CATALYTIC MUFFLER HAVING CROSSOVER PASSAGEWAY FOR SECONDARY AIR - A catalytic muffler that treats the exhaust gases of an internal combustion engine. The catalytic muffler includes a catalyst chamber, a catalyst disposed in the catalyst chamber, an upstream chamber disposed upstream of the catalyst, an exhaust inlet configured to receive exhaust gases, an exhaust outlet configured to discharge converted gases converted by said catalyst to the atmosphere, and further configured to receive secondary air, and a passageway communicating between the exhaust outlet and the upstream chamber, and configured to provide the secondary air received by the exhaust outlet to the upstream chamber. | 12-03-2009 |
20150036267 | METER SOCKET ADAPTER WITH INTEGRATED AUTOMATIC TRANSER SWITCH - A transfer switch and load controller that can be plugged into an existing utility meter socket and electrically positioned between the meter socket and a distribution panel to allow switching between utility power and standby power. The plug-in transfer switch functions to transfer the power supplied to a home between the utility power source and the generator power source upon loss of power from the utility power source. The transfer switch components are contained in an enclosed housing of a meter socket adapter that is mounted directly to the meter socket of a meter housing. The meter socket adapter is prewired to a standby generator such that the standby generator can be connected to a home power system by plugging the meter socket adapter into the meter socket | 02-05-2015 |
20150053505 | ENGINE OIL RECIRCULATION SYSTEM FOR EXTENDED MAINTENANCE INTERVAL - An oil recirculation system for an internal combustion engine includes an oil sump for storage of engine oil, a supplemental oil tank configured for storage of supplemental engine oil therein, and a conduit configured to fluidly couple the supplemental oil tank and the oil sump such that supplemental engine oil from the supplemental oil tank is selectively delivered to the oil sump and engine oil is selectively extracted from the oil sump and delivered to the supplemental oil tank. The system is configured to deliver supplemental engine oil to the oil sump from the supplemental oil tank and extract engine oil from the oil sump to the supplemental oil tank during a predetermined time period. | 02-26-2015 |

20110081261 | PRESSURE WASHER PUMP AND ENGINE SYSTEM - A pressure washer system includes an engine block, a water conduit, a water pump, and a spray gun. The engine block is for a horizontally-shafted internal combustion engine, and has a chamber therein. The chamber is designed to contain oil for cooling and lubricating the internal combustion engine. The water conduit has a garden hose connector on an end thereof, and is fastened to the engine block. As such, heat transfers from the engine block to a flow of water passing through the water conduit during operation of the internal combustion engine. The water pump is coupled to the water conduit, where the flow of water is driven by the water pump. The spray gun is coupled to the water pump, where the flow of water exits the pressure washer system via the spray gun. | 04-07-2011 |
20110308236 | MUFFLER AND ENGINE SYSTEM - A muffler for a combustion engine includes walls forming a chamber, a first inlet, a first outlet, and a conduit. The first inlet is designed to receive exhaust gases from an exhaust duct of the engine. The exhaust gases pass through the chamber when moving from the first inlet to the first outlet. The exhaust gases then exit the muffler through the first outlet. The conduit extends between a second inlet and a second outlet. The second inlet is configured to receive fresh air entering the muffler. The fresh air then exits the conduit and is introduced into the exhaust gases through the second outlet. | 12-22-2011 |
20120097482 | SYSTEM FOR CHECKING OIL LEVEL - An engine includes a volume configured to hold oil for lubricating components of the engine, a pump, a conduit coupled to the pump and extending into the volume, and a visual interface coupled to the conduit. The conduit includes an opening located on the conduit at a position associated with a desired level for oil in the volume. When oil in the volume is at least up to the desired level, operation of the pump draws oil from the volume through the opening and into the conduit. The visual interface communicates whether or not oil in the volume is at least up to the desired level. | 04-26-2012 |
20130277145 | MUFFLER AND ENGINE SYSTEM - A muffler for exhaust gases of a combustion engine includes walls forming a chamber through which the exhaust gases pass, a first inlet in the walls of the chamber configured to receive the exhaust gases from an exhaust duct of the engine, a first outlet in the walls of the chamber through which the exhaust gases exit the chamber, and a conduit having a second inlet and a second outlet, wherein a substantial length of the conduit is positioned within the chamber. | 10-24-2013 |
