20110030640CHOKE AND PRIMING SYSTEM FOR AN INTERNAL COMBUSTION ENGINE - An internal combustion engine that includes a carburetor having a choke valve and an actuator configured to move the choke valve between a closed choke position and an open choke position. A passageway is configured to direct a pressure pulse from the engine into a fuel chamber of the carburetor. The engine further includes a priming valve at least partially located within the passageway. The priming valve is configured to move between an open primer position that allows the pressure pulse to enter the fuel chamber through the passageway and a closed primer position that substantially restricts the pressure pulse from entering the fuel chamber through the passageway. The priming valve is configured to move between the open primer position and the closed primer position by the actuator when the actuator moves the choke valve between the closed choke position and the open choke position, respectively.02-10-2011

A transfer switch is electrically connected to the primary and secondary power sources, and a plurality of branch circuits are electrically connected to the transfer switch. The plurality of branch circuits includes a plurality of electrical outlets. The system includes a controller wirelessly coupled to a plurality of portable receptacles, which are coupled between respective electrical outlets and managed devices. The controller manages the receptacles, and consequently the managed devices, during the second power source powering the transfer switch.09-09-2010
20100147264FUEL SHUTOFF SYSTEM - A fuel control system that has a fuel control device to control the flow of fuel to a carburetor of an internal combustion engine. The fuel control device includes a control member that is movable between a first position and a second position to control the flow of fuel into a carburetor. When a kill switch within the fuel control system is closed, induced current from a primary ignition coil within the internal combustion engine is fed through an electromagnetic coil, causing the fuel flow control device to interrupt the supply of fuel to the carburetor. Thus, when an operator desires to stop the internal combustion engine, the kill switch closes and the fuel control device interrupts the supply of fuel to the carburetor to prevent backfires.06-17-2010
20100114464SMART TRACTOR INCLUDING COMMUNICATION SYSTEM AND ENGINE STARTING SYSTEM - An engine control, communication and starting system for outdoor power equipment that has a controller and a one or more safety interlocks. The controller monitors the status of the safety interlocks to determine whether the internal combustion engine can be started upon activation of a starting device. If the starting device is activated and one or more of the safety interlocks is in a condition that prevents operation of the engine, the controller generates a feedback message to the operator through a feedback system. The feedback message can be either an audible or visual message that relays information to the operator. The system further includes a speed selection circuit that allows the operator to select the desired engine speed. The controller operates the internal combustion engine at the selected engine speed. During engine operation, the controller terminates operation of the engine if any of the safety interlocks move to an un-allowed status.05-06-2010
20090260596IGNITION AND FUEL SHUTOFF FOR ENGINE - A carburetor assembly includes a carburetor, a fuel supply valve, a valve member and a normally open switch. The fuel supply valve is coupled to the carburetor housing and is fluidly connected to the carburetor. The fuel supply valve includes a lever pivotable between first and second positions. The valve member is configured to move in response to the lever such that fuel is allowed to flow to the carburetor when the lever is in the first position and fuel is not allowed to flow to the carburetor when the lever is in the second position. The normally open switch is adjacent the fuel supply valve and includes a switch actuator. The lever is configured to engage and release the switch actuator to move the switch actuator between a non-actuated position and an actuated position respectively when the lever moves between the first and second positions.10-22-2009
20090240377POWER MONITORING SYSTEM - The invention provides a hierarchically accessible monitoring system configured to be used with a standby generator, and a method of remotely accessing generator information from a standby generator. The hierarchically accessible monitoring system includes an interface unit configured to receive information from the standby generator and to communicate the generator information, and a remote data server in communication with the interface unit. The remote data server receives the generator information from the interface unit, stores the generator information, and controls access to the generator information based upon at least two hierarchical levels, each hierarchical level having different access privileges. The hierarchically accessible monitoring system also includes a user interface configured to display the generator information from the remote data server to at least one user. The user has access privileges to read the generator information based upon the user's assigned hierarchical level.09-24-2009
20090236860GENERATOR SET - A generator system for a portable, residential or small business generator includes an engine, an alternator, a continuously variable transmission pulley system and a governor. The engine includes a drive shaft and a throttle. The alternator includes a rotor disposed on a rotor shaft. The continuously variable transmission pulley system includes a drive pulley coupled to the drive shaft, a driven pulley coupled to the rotor shaft, and a belt configured to engage the drive pulley and the driven pulley. The governor adjusts the engine throttle to control the speed of the engine in response to a speed of the rotor shaft.09-24-2009
20090232674ENGINE STARTER ASSEMBLY - A pressure washer, connected to a water source by a hose, includes a frame, an engine supported by the frame and having a crankshaft, a pump driven by the engine, a wheel supported for rotation relative to the frame, an input configured to receive water from the hose and discharge the water against the wheel to cause the wheel to rotate, and a spring having a first end that is coupled to the crankshaft and a second end that is rotatable about an axis relative to the first end in response to rotation of the wheel to wind the spring. The wound spring is released to rotate the crankshaft to start the engine.09-17-2009
20090058191TRANSFER SWITCH - A system for use with an electrical distribution panel having a bonded neutral connection. In some embodiments, the system includes a generator having a first bonded neutral connection and a ground fault circuit interrupter. The system also includes a neutral bus that is connected to either the bonded neutral connection of the distribution panel or the bonded neutral connection of the generator. Additionally, the system includes a switch for disconnecting the neutral bus from the bonded neutral connection of the distribution panel and connecting the neutral bus to the bonded neutral connection of the generator.03-05-2009
