Abstract: An apparatus is provided for modifying a crankshaft angle of an internal combustion engine (ICE). An energy converter is configured to be connected to a crankshaft of the ICE. An energy storage unit is configured to deliver energy to the energy converter when the energy converter acts as a motor, and to store energy output from the energy converter when the energy converter acts as a generator. The controller is configured to calculate a current ideal crankshaft angle, calculate a current slip angle using an output of a crankshaft angle sensor, activate the energy converter as a motor to increase the current crankshaft angle when the current slip angle is greater than a predetermined upper threshold value, and activate the energy converter as a generator to decrease the current crankshaft angle when the current slip angle is less than a predetermined lower threshold value.

Abstract: A first generator set may store, in a memory of the first generator set, data representing local attributes associated with an engine. The first generator set may receive, via a network switch of the first generator set, remote data representing remote attributes associated with a second generator set. The first generator set may cause the first controller to update, based on the remote data, the local data in the memory to synchronize the local attributes with the remote attributes. The first generator set may transmit, via the network switch, an indication that the local data was successfully updated in the memory.

Abstract: A vehicle for agricultural use has wheel groups, an engine group, an engine control unit, auxiliary operating groups, a gearbox group, a power take-off group, and a detection system having an engine power detector for detecting an engine power value, an auxiliary power detector for detecting an auxiliary power value, a drive power detector for detecting a drive power value, and an operating unit operatively connected to the detectors to receive the engine power value, auxiliary power value, and drive power value and suitable for identifying a take-off power value corresponding to power used by the power take-off group. The operating unit checks the drive power value with respect to a drive threshold value and/or the power take-off power value with respect to a power take-off threshold value and is connected to the engine control unit to control supply of the engine group as a function of check results.

Abstract: An outboard motor includes an engine, a generator to generate power by driving of the engine, a driving force transmitter to transmit a driving force from the engine, a propeller shaft to rotate by being switched from a neutral state in which a clutch is disconnected from the driving force transmitter of the engine at idle to a non-neutral state in which the clutch is connected to the driving force transmitter, and a controller configured or programmed to perform a control to reduce a rotation speed of the engine by regeneration of the generator based on a user's switching operation on a shift operator to switch the outboard motor from the neutral state to the non-neutral state, and then connect the clutch to the driving force transmitter while rotating the engine.

Abstract: A standby generator includes a standby housing defining a cavity and an internal combustion engine. The engine includes an engine block including a cylinder comprising a piston, an engine housing at least partially covering the engine block, and a crankshaft configured to rotate about a vertical crankshaft axis in response to movement by the piston. The standby generator also includes an alternator configured to generate alternating current electrical power, a controller comprising a rectifier configured to convert the alternating current to a direct current and an inverter configured to convert the direct current to a clean alternating current electrical power, and a transfer switch configured to receive the clean alternating current electrical power from the controller and at least one of grid, solar, or battery power, and configured to supply power to an electrical load. The internal combustion engine, the alternator, and the controller are positioned within the cavity.
