    摘要： An internal combustion engine includes an engine housing, a crankshaft supported within the engine housing for rotation with respect to the engine housing, and a flywheel fixedly mounted to the crankshaft and rotatable with the crankshaft in a starting direction to start the engine. A coil spring has an outer end fixedly interconnected with respect to the engine housing, and an inner end. A unidirectional clutch has a portion connected to the inner end of the spring. The unidirectional clutch is characterized by an interference condition in which the unidirectional clutch couples the inner end of the spring to the flywheel such that the flywheel and crankshaft may be rotated in the starting direction in response to unloading of the spring. The unidirectional clutch is also characterized by a non-interference condition in which the inner end of the spring is uncoupled from the flywheel. An input assembly is interconnected with the spring and selectively movable into contact with flywheel to load the spring in response to rotation of the flywheel. A locking mechanism selectively prevents the spring from unloading, and at least one manual actuator is actuable to disengage the locking mechanism from the spring to enable unloading of the spring.

    摘要： An internal combustion engine includes a spring housing rotatably mounted to the engine's engine housing for rotation about an axis of rotation. An energy storing mechanism including at least one elastic member is housed within the spring housing. A spring loading mechanism includes at least one roller movable into and out of engagement between the engine's flywheel and the spring housing, such that rotation of the flywheel is converted through the at least one roller to cause rotation of the spring housing in a direction that loads the elastic member. An engine starting mechanism includes a helically threaded member interconnected with the spring housing and a starter pinion threaded onto the helically threaded member. Rotation of the spring housing in response to unloading of the elastic member causes the starter pinion to move into engagement with the flywheel, thereby rotating the flywheel and starting the engine.

    摘要： An engine starting and stopping device includes a first roller selectively abutting the flywheel of an engine for rotation on a first shaft in response to rotation of the flywheel. A second roller abuts the first roller and rotates in response to rotation of the first roller. A second shaft and an overwind clutch couple the second roller with a third roller such that the third roller rotates in response to rotation of the second roller. The third roller abuts a spring housing and causes rotation of the spring housing in response to rotation of the third roller. A spring is housed within the spring housing and is loaded in response to rotation of the spring housing. The overwind clutch slips when the spring is loaded to a preselected level to protect the spring from overwinding. The spring is selectively unloaded to rotate the spring housing in an unloading direction. Rotation of the spring housing in the unloading direction causes rotation of the engine's crankshaft and startup of the engine.

    摘要： An internal combustion engine includes an engine housing and a crankshaft supported for rotation within the engine housing and rotatable in a starting direction to start said engine. At least one cup is fixedly mounted to the crankshaft for rotation therewith. A starter shaft is supported by the engine housing for rotation. A spring housing includes a circumferential flange that defines an annular track with the at least one cup, and a spring is housed within the spring housing. The spring has a first end interconnected with the spring housing and a second end interconnected with the engine housing. A friction roller is movable into the annular track and into engagement with both of the circumferential flange and the at least one cup to cause rotation of the spring housing and loading of the spring in response to rotation of the crankshaft. A unidirectional clutch is interconnected between the spring housing and the starter shaft, the unidirectional clutch causing rotation of the starter shaft in a starting direction in response to unloading of the spring, but not causing rotation of the starter shaft in a direction opposite the starting direction. At least one dog is interconnected with the starter shaft to engage the at least one cup in response to rotation of the starter shaft in the starting direction to thereby causes rotation of the crankshaft in the starting direction.

    摘要： The automatic enrichment mechanism for an internal combustion engine is thermally-responsive and may also be centrifugally-responsive. The invention increases engine startability and minimizes stumbling and stalling of the engine during engine warmup. The thermally-responsive mechanism allows an additional reverse gas flow through the intake manifold to thereby increase the fuel discharged by the carburetor fuel nozzle. In several embodiments, the thermally-responsive mechanism, at low engine temperatures, causes a blocking or retaining member to keep an auxiliary cam member engaged with the cam follower of the valve assembly. As a result, the intake valve is partially unseated at low engine temperatures and a portion of the air/fuel mixture is fed back to the intake manifold. In these embodiments, when the engine temperature reaches a predetermined level, the thermally-responsive mechanism allows the auxiliary cam member to disengage from the cam follower in response to centrifugal force on the flyweights. In other embodiments, the thermally-responsive device allows crankcase gases to be fed to the intake manifold downstream of the fuel nozzle, causing a reverse flow of gas through the carburetor. The thermally-responsive member may be made from a thermal actuating polymer, commercial wax, bimetallic material, or from a nickel-titanium alloy which contracts at a predetermined engine temperature.

    摘要： 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.
