摘要:
Several embodiments of outboard motors having four cycle internal combustion engines wherein one or more fuel pumps are directly driven by the lobes of the camshafts that operate the valves of the engine. This provides a very compact assembly, permits latitude in the location of the fuel pump or pumps and also minimizes the number of driving connections that are required.

An exhaust manifold for an outboard motor that has a vertically extending crankshaft and which exhaust manifold is formed in the cylinder head and cylinder block. The cylinder block forms the exhaust manifold by runner sections that are configured in such a way so as to facilitate the casting process by which they are formed and which provide an effective smooth flow path without requiring complex cores or patterns.

Each CPU registers jobs of its own in the form of nodes in a normal node queue, executes the registered jobs in a registration order, has a queue (remote node queue) for registering a job requested by another CPU in the form of a node, and executes the remote nodes in a registration order as in the normal nodes. When the first CPU causes the second CPU to execute a job, the first CPU transmits the job in the form of a node processed by the second CPU. The second CPU registers the received node in the remote node queue and executes it as in the normal node. The second CPU sends back, to the first CPU, the processing result of the received node in the form of a node processed by the first CPU, as needed.

An induction system for an outboard motor of the type having a water propulsion device powered by an internal combustion engine positioned within an engine compartment defined by a cowling, is disclosed. The induction system includes a cover extending over a top end of the engine. The cover defines an air duct leading from an intake chamber defined by the cowling to an intake pipe of the air intake system of the engine. The cover also defines an air duct in communication with the engine compartment and leading to an exhaust chamber defined by the cowling. A pair of intake ports lead through a cover of the cowling from the intake chamber, and an exhaust port leads through the cover from the exhaust chamber. The intake ports are positioned forward of the exhaust port when considering the forward movement of a watercraft which is powered by the motor.

An information processing method and apparatus includes elements and steps to rapid figure editing and its execution environment by quickly executing a program and a file from a diagram showing a flow of the program and file. According to the invention, a rectangular figure object in which a line width is set to "0.2 mm", a line type is set to "solid line", and a line color is set to "black" and which is filled by a pattern of a "diagonal-1" of "red" is pasted to a drawing sheet by using a mouse or the like by the user. After a character attribute "dir" was pasted to the rectangular object by using a keyboard, for example, when an instruction to point the rectangular object by using the mouse or the like or to depress a button of the mouse while depressing a control key of the keyboard, or the like is performed, a command interpreter stored in a memory device is activated by a CPU, the character attribute "dir" of the rectangular object is read out, the characters "dir" are sent to the activated command interpreter, and the computer command "dir" is executed, so that the above object can be accomplished.

A fuel injection system for an internal combustion engine of the type utilized to power an outboard motor of a watercraft is disclosed. The engine is oriented with its crankshaft vertically extending, such that the engine has a top and a bottom, a first end and a second end, and a side between the ends. An air delivery passage extends generally from the first end along said side to an intake passage leading through the engine to a combustion chamber therein. A fuel injector is positioned along the side of the engine and arranged to deliver fuel into air flowing through the passage. In one arrangement, the fuel injector is connected to an intake manifold defining at least a part of the air delivery passage and is adapted to deliver fuel opposite the flow of air through the passage at the point of delivery. In a second embodiment, the fuel injector is positioned between the air delivery passage and the side of the engine. In this embodiment, the fuel injector is preferably arranged to deliver fuel perpendicular to the flow of air through the passage.

A fuel injected induction system for a crankcase compression, two-cycle, V-type internal combustion engine includes a plurality of throttle valves corresponding in number to the number of crankcase chamber of the engine. Each throttle valve communicates with a dedicated intake passage that directly communicates with a respective crankcase chamber. At least one fuel injector is positioned within each intake passage in order to form the air/fuel charge delivered to the crankcase chamber. The corresponding number of throttle valves, fuel injectors and crankcase chambers allows for enhanced control over the air-fuel ratio delivered to each of the cylinders, as well as improved consistence of the air-fuel charge delivered to each of the cylinders of the engine.

A number of embodiments of four-cycle V-type outboard motors embodying an improved and simplified oil filter arrangement wherein the oil filter is easily accessible for servicing is located in close proximity to the oil tank for facilitating pressure relief and is disposed so as to facilitate communication with the main oil gallery of the engine.
摘要:
A high-performance outboard motor embodying a V-type four overhead camshaft four-cycle internal combustion engine. A compact cam driving arrangement is provided for driving the camshafts from the crankshaft of the engine at the upper end. A flywheel is mounted to the lower end of the crankshaft and is driven by a starter motor for starting of the engine. Another engine accessory is driven off the upper end of the crankshaft so as to maintain a compact and yet highly serviceable arrangement.
