摘要： A protective cowling arrangement defining an air inlet opening for an outboard motor that facilitates the ingestion of large amounts of air at low velocity. This aids in the assurance that water is not ingested into the engine. The configuration of the inlet opening is such that the water that is separated by the inlet system can easily flow away from the inlet opening and also the water that collects on the housing surfaces can be easily separated and will drain away from the actual inlet openings into the interior of the cowling.

摘要： In an outboard motor having a fuel-injected two-cycle engine, engine speed, throttle setting, engine boost pressure, and/or other variables are detected and a basic fuel injection volume determined. Fuel is supplied to each of the engine's cylinders according to the detected values. When the engine is stopped, information about the operating conditions of the engine before the engine was stopped are saved in a memory of a controller. These saved values represent the residual fuel volume left in the engine's cylinders at a subsequent start-up of the engine. The saved values are used to correct the basic fuel injection volume determined at start-up by the controller.

摘要： A flange portion formed on an inner periphery of a flywheel is facet-fitted to an end of a crankshaft. A spline piece is facet-fitted to an inner peripheral surface of the flywheel. The flange portion of the flywheel and a flange portion of the spline piece are commonly fastened to the end of the crankshaft by bolts. An upper end of a driving shaft is spline-fitted at a point into a driving shaft coupled portion of the spline piece which is accommodated in an internal hole in the crankshaft. Thus, in coaxially coupling the flywheel and the driving shaft to the end of the crankshaft, it is possible to make such a coupled area compact and to reduce vibration by an accurate centering thereof.

摘要： To prevent deformation, in the upper portions of cylinder bores, that occurs when the cylinder head is mounted on the cylinder block by using head bolts and to prevent deformation in the upper portions of the cylinder bores caused by the thermal expansion of the cylinder head. In an open deck type cylinder block of an internal combustion engine in which the cylinder bores are separated from the outer shell of the cylinder block by water jackets in the upper deck, thick portions are formed near the ends of the cylinder bores located at both ends of the internal combustion engine in the direction of the crank shaft, the end portions being opposed to the outer shell of the cylinder block in the axial direction of the crank shaft, the thick portions being smoothly continuous with the outer shell of the initial cylinder bores. The thick portions have the greatest thickness at the ends in the direction of the crank shaft. A decreased-diameter portion having a thickness smaller than that of the upper portions is formed in the lower portions of the cylinder bores neighboring the regions where the thick portions are formed, and the decreased-diameter portion and the ordinary cylinder bores of the upper portions thereof are connected together through the tapered portion to decrease the weight of the cylinder block.

摘要： An air intake system for an engine powering an outboard motor is disclosed. The engine is positioned within a cowling of the motor, the cowling including an air intake vent. The engine is vertically positioned, having a camshaft drive at an upper end thereof, the camshaft drive enclosed by a drive cover. An air passage is defined between the drive cover and cowling and leads from the vent to an engine air intake. The air intake comprises a passage formed by the cover and extending therethrough. The passage through the cover leads to a throttle body having a throttle plate therein, the throttle body connected to a surge tank from which runners extends to provide air to the combustion chambers. Air flows through the passage in the cover through a flexible hose member extending between the cover and the throttle body.
