  • Patent number: 9499248
    Abstract: There is provided a toe angle control system for outboard motors. A memory stores therein a toe angle data table in which a running state of a ship and a lifting force generated along with propulsion of a plurality of outboard motors which are mounted on a body of the ship are associated with each other for each toe angle of the outboard motors. A controller is configured to adjust a toe angle of the outboard motors based on the running state of the ship and the toe angle data table. The toe angle data table is adapted to be associated with a plurality of running states of the ship mounted with the outboard motors. The controller selects a toe angle of the outboard motors so as to minimize the lifting force depending on a speed of the ship and trim angles of the outboard motors.

  • Patent number: 9347417
    Abstract: In the process of starting by a recoil starter, a maximum value detection section of an ECM detects a maximum value of pressure (basic atmospheric pressure) in an intake pipe detected by a pressure sensor, within a predetermined range of crank angle after activation of the ECM. An idling control unit gives feedback control on an ISC valve based on engine speed detected by an engine speed sensor, to thereby keep idling engine speed at a specified value. A correction unit corrects a basic atmospheric pressure detected by the maximum value detection section based on the duty ratio of the ISC valve in idling, and uses the result as the atmospheric pressure. A storage unit 9d stores a map in which the duty ratio of the ISC valve in idling is correlated with the amount of correction to be made on the basic atmospheric pressure.
