摘要： An improved supporting arrangement for an outboard motor or marine outboard drive wherein a pair of links are pivotally connected at one of their ends to the transom of the associated watercraft and at the other of their ends to the outboard drive for movement of the outboard drive between a trimmed down position and a tilted up out of the water position. One of the links is expandible in length and a fluid motor is provided for this purpose. In addition, a further fluid motor is pivotally connected between one of the links and the transom for effecting the pivotal movement. Various alternative linkage arrangements are illustrated.

摘要： A combustion chamber and scavenging configuration for a two-cycle internal combustion engine. The combustion chamber is comprised of an offset recess surrounded by a squish area. An exhaust port is formed on the side of the cylinder opposite to the area where the recess is offset while the intake or transfer ports are disposed on the side to which the recess is offset. The transfer or scavenge ports are configured so as to open progressively first diametrically opposite to the exhaust port and then in an area extending around the area toward the exhaust port.

摘要： Several embodiments of engine speed control mechanisms that permit the running speed of an engine to be maintained at a predetermined value. The mechanical components of the system include a linkage system that connects an operator position throttle control with the throttle valves of the engine and that incorporates a lost motion connection so that the throttle valves may be positioned independently of the operator throttle control to maintain the speed control. In one embodiment of the invention, the throttle and speed control mechanism is mounted on the engine while in another embodiment, these components are mounted remotely from the engine. In one embodiment of the invention, a control circuit is provided that prevents hunting.

摘要： A lubricating system for a two cycle engine, particularly of the outboard type, wherein the engine has a separate lubricating system and lubricant is supplied to this system by a relatively small delivery tank via gravity feed. In addition, an arrangement is provided for supplying lubricant to the delivery tank from a separate oil storage tank to maintain a predetermined liquid level in the delivery tank. This system includes a pump located in the separate storage tank. In accordance with certain embodiments of the invention, the pump is operated if the liquid level in the delivery tank falls below a predetermined level. In accordance with one embodiment, the operation of the pump is stopped when the liquid level exceeds a predetermined level.

摘要： A number of embodiments of treating the exhaust gases of an internal combustion engine with a catalyzer so as to render lubricant in the exhaust gases in a non-polluting form. A number of embodiments applying this principle to marine propulsion units are illustrated and described which include outboard motors and inboards. In each embodiment, the catalyst is position so that the exhaust gases will impinge upon it but need not flow through it for their discharge to the atmosphere. In addition, the exhaust system is designed in such a way that the catalyst may be removed and replaced simply by the use of a removable wall section of the exhaust system.
