摘要： A four-cycle engine including a magnetic detection sensor mounted on a non-magnetic cam shaft pulley which is rotated in operative association with a crank pulley for detecting a plurality of detecting portions formed on the magnetic detection member by coils mounted in the cylinder head. The magnetic detection member is integrally formed with the plurality of detection portions for different uses such that distances from the center of rotation of the cam shaft pulley to the plurality of detection portions are different, and wherein the coils are separately mounted in correspondence to the detection portions. Thus, it is possible not only to take out timing signals for different uses from a single cam shaft pulley, but also to eliminate interference between the discrete coils.

摘要： A four-cycle engine for an outboard motor includes an upwardly extending breather chamber which communicates with a projecting portion provided at a lower part of a crankcase and with an induction system via a PCV passage for returning a blow-by gas to intake manifolds. With this arrangement, it becomes possible to remove oil components from the blow-by gas within the PCV passage and hence to return the substantially oil-free blow-by gas to the intake manifolds.

摘要： An idling speed control system for an outboard motor mounted on a boat and equipped with an internal combustion engine, whose output is connected to a propeller through a clutch, having secondary air supplier that supplies secondary air. In the system, the engine start-state as to whether the engine has been started is determined and the clutch position is detected and based thereon, the desired idling speed and the desired secondary air supply amount is determined through learning control. With this, the system can therefore accurately determine the desired idling speed and the desired secondary air supply amount and achieve steady idling speed even if load changes owing to a change in clutch position or propeller replacement.

摘要： An engine ignition timing control system for outboard motor having a propeller connected to the engine to be rotated and mounted on a boat such that the boat is propelled forward or backward. The engine is equipped with a decompression mechanism and is started by a recoil starter. In the system, at the time of engine starting, the ignition timing is set to a predetermined crank angle until the detected engine speed exceeds a first prescribed engine speed, while it is set to a value obtained by retrieving a table by at least the detected engine speed after the detected engine speed exceeds the first prescribed engine speed. And, the ignition timing is advanced until the detected engine speed is equal to or greater than a second prescribed value and is then returned to the retrieved value. With this, the engine speed can be reliably increased at starting, without need for a throttle opener or air-fuel ratio enrichment, thereby enhancing engine starting performance.

摘要： An oil pressure switch failure detection system for an outboard motor, having a first oil pressure switch which generates an ON signal indicating that the oil pressure is less than or equal to a first predetermined oil pressure and a second oil pressure switch which generates an ON signal indicating that the oil pressure is less than or equal to a second predetermined oil pressure which is set higher than the first predetermined oil pressure. In the system, by discriminating whether the generated signals of the first and second oil pressure switches are equal to be expected signals expected under operating conditions of the engine, it is determined whether at least one of the first and second oil pressure switches fails. With this, it become possible to detect failure of the first and second oil pressure switches, accurately.

摘要： A control apparatus for controlling an engine mounted on a watercraft and driving it so as to finely and stably control a low speed of the watercraft. The control apparatus is adapted to compute a target engine speed on the basis of a correction value for the engine speed which is determined by a correction signal generated by a correction signal generator which is manually operable. The control apparatus controls the opening degree of the secondary air valve in accordance with a desired opening computed on the basis of the computed target engine speed.
