56 108, 1231791

Abstract:

A lawn mower includes an internal combustion engine, an electric motor configured to start the internal combustion engine, and a blade driven by the internal combustion engine. The lawn mower further includes an assembly for stopping at least one of the blade and the internal combustion engine. The assembly includes a brake mechanism, a release mechanism, a linkage between the brake mechanism and the release mechanism. The assembly further includes an interlock configured to prevent the release mechanism from releasing the brake mechanism, and an interface allowing an operator to release the interlock. The electric motor is coupled to the assembly such that release of the brake mechanism automatically engages the electric motor to start the internal combustion engine.

H02J 1/00

Abstract:

An operating system for a standby generator includes a control unit, a switch, an inverter, a terminal, a current sensor, a starter circuit, a power control circuit, and an ignition kill circuit. The control unit is powered by a rechargeable twelve volt DC battery. The switch is selectively operable by the control unit to connect one of a first input or a second input to an output. The second input receives the supply of electrical power from an internal combustion engine. The inverter is positioned between the DC battery and the first input, and supplies electrical power to the electrical device when a movable contact of the switch connects the output to the first input. The power control circuit is connected to the control unit and is operable to adjust the movable contact of the switch to selectively connect the output to either the first input or the second input.

H01M 2/10
F02N 11/14

Abstract:

A battery pack for use in providing starting power for a starter motor of an internal combustion engine and to supply power to one or more auxiliary loads. The battery pack includes an outer housing that encloses a plurality of battery cells. A control unit is positioned within the outer housing and is connected to at least a starter switching element and an auxiliary switching element. The control unit controls the position of both the starter switching element and the auxiliary switching element to selectively connect the battery cells to the starter motor and the auxiliary loads. The battery pack further includes an ignition input terminal that is connected to the ignition circuit of the internal combustion engine such that the control unit can monitor the operational status of the internal combustion engine. The control unit can selectively ground the ignition coil of the ignition circuit to enable and/or terminate operation of the internal combustion engine.

H02J 7/00
H02J 1/00

Abstract:

An on-demand generator starting system and method is disclosed. The generator starting system is included as part of a standby or portable generator that includes one or more outlets that provide electrical power to an electrical device. The operating system includes a generator controller that monitors for a request for power from the electrical device connected to the outlet. When the control circuit of the generator controller determines that electric power is required from the generator, the control circuit initiates operation of the internal combustion engine. After the internal combustion engine starts, the control circuit operates a relay to provide power from the generator to the outlet of the generator. When the electrical device is no longer operating, the control circuit of the generator controller terminates operation of the internal combustion engine of the generator. In this manner, the generator operates only when the electrical device is requesting electrical power.

International Classification:

H02K 3/26
H02K 11/00
H01F 5/00
F02N 11/08

Abstract:

A device including a number of printed circuit board layers assembled in a stack that functions as a starting device for an internal combustion engine. Each of the circuit board layers includes a number of loops formed by copper traces on a dielectric substrate and each oriented in a coiled pattern. A rotor, which may take the form of a flywheel, is closely spaced from the stack of printed circuit board layers and includes a series of permanent magnets. When alternating current is supplied to the circuit board layers, the magnetic fields created by the loops induce rotation of the rotor. The device can operate in an alternator mode in which the device generates current as the rotor rotates past the loops on the circuit board during operation of the internal combustion engine.

International Classification:

F02P 3/05
F02P 15/12
F02P 1/02

Abstract:

A system and method for enhancing spark generation in an ignition coil of an internal combustion engine at low rotational speeds of the flywheel. The method and system monitor the rotational speed of the flywheel and, when the rotational speed of the flywheel is below a threshold rotational speed, the system and method supplies voltage pulses to the primary winding. The timing of the voltage pulses supplied to the primary winding are triggered off of voltage transitions in pulses induced in the primary winding upon rotation of the flywheel. Once the internal combustion engine has started, the switching device transitions into a second condition to disconnect the electrical storage device from the primary winding. The spark generation system of the present disclosure allows for starting of an internal combustion engine upon slower initial rotational speeds.

F02N 11/10

Abstract:

A starter motor that includes an integrated solid state switching device. The solid state switching device is mounted within the outer housing of the starter motor such that the entire starter motor can be installed as a single unit. In one embodiment, the solid state switching device includes a MOSFET positioned on the low side of the starter motor. The solid state switching device opens and closes to control the flow of current through the starter motor. In another embodiment, the solid state switching device is positioned on the high side of the starter motor. The solid state switching device can include a speed sensing circuit to prevent operation of the starter motor when the internal combustion engine is operation, a crank limiting circuit that limits the amount of time the starter motor can operate without starting the internal combustion engine and/or a thermal limiting circuit to prevent operation during overheating of the starter motor.
