Abstract: Embodiments of two-cycle crankcase compression direct injected internal combustion engines that permit good firing and effective stratification, particularly at low speed, low load conditions. The engine defines a combustion chamber having a recess with a projection extending into the center of the recess and against which fuel is injected by a fuel injector as the piston approaches top dead center at idle. The spark plug firing is initiated prior to completion of the fuel injection. A specific configuration and orientation for the fuel injector nozzle in relation to the projection size and cylinder bore size is established so as to insure that at least 50% of the fuel injected at low and idle speed conditions will impinge upon the projection.

Abstract: A vulcanizing method including a cylindrical vulcanizing drum for winding and molding unvulcanized rubber belt materials thereover, the vulcanizing drum being removably and rotatably supported on a transfer mechanism. A pair of endless pressurizing bands are arranged to oppose each other with the vulcanizing drum between, the pressurizing bands arcuately surrounding and pressing the corresponding portions of the circumferential surface of the vulcanizing drum. While the circumferential surface of the vulcanizing drum is heated inside, and the respective pressurizing bands are opposingly pressed against the vulcanizing drum, the respective pressurizing bands are synchronously rotated so as to turn the vulcanizing drum and continuously vulcanize the unvulcanized rubber belt molding on the drum.

Abstract: A near infrared screening filter glass consisting essentially of from 35 to 60 wt. % of P.sub.2 O.sub.5, from 10 to 30 wt. % of Al.sub.2 O.sub.3, from 1.5 to 15 wt. % of SiO.sub.2, from 3 to 15 wt. % of B.sub.2 O.sub.3 and from 0.1 to 10 wt. % of CuO.

Abstract: Two embodiments of air/fuel injectors wherein the fuel is injected to a chamber through a venturi section that receives pressurized air so that the fuel is injected to an area of lower pressure than the air pressure. The chamber is communicated with the engine through an injector valve which opens and closes. The isolation of the point of fuel delivery from the injector valve reduces the likelihood of fuel variations due to variations of the lift of the injector valve. In one embodiment, the venturi section is formed co-axially with the chamber and in another embodiment it is formed externally of the chamber.

Abstract: A two cycle crankcase compression internal combustion engine including an air/fuel injector unit for injecting fuel and air into the engine. Compressed air is delivered to the fuel/air injector unit from an air compressor and a heat exchanger is provided in this line for cooling the air. The cooling is sufficient to cause condensation of any water vapor in the air and the condensate is drained from the system after the engine is stopped through an electrically operated valve. This valve also serves to reduce the pressure of the air in the system when the engine is stopped so that fuel and air will not be discharged if the fuel/air injector unit is removed when the engine is shut down for servicing.

Abstract: Several embodiments of internal combustion engines as applied to outboard motors incorporating a combined electrical generator and air compressor unit driven by the engine output shaft and having a single input shaft that drives both the electrical generator and the air compressor. The air compressor supplies compressed air for a fuel/air injection system and the combined unit is disposed in a recess formed by the engine so as to provide a compact assembly.

Abstract: A bearing for receiving a crankshaft positioned in a crankcase of an inboard/outboard internal combustion engine which includes a seal member for sealing the inside of the bearing so as to prevent corrosion of the bearing. Preferably, the crankcase includes a plurality of crank chambers to accommodate a crankshaft rotatably received by a plurality of bearings, each of which includes a seal member.

Abstract: An ignition timing control system for an internal combustion engine including a throttle position sensor and a translational mechanism for transmitting movement of the throttle valve into a desired movement of the throttle position sensor so as to achieve variations in the spark advance angle without necessitating reconfiguration or recalibration of the ignition circuit.

Abstract: An improved method and apparatus for mixing fluid and/or granular substances, whereby greater mutual dispersion of at least two substances is achieved by attaining greater turbulence while minimizing the required amount of mechanical structure. Each of at least two substances is fed at a different angle in a belt-shaped stream to a nozzle, under pressures according to the viscosity of each substance. After initial mutual dispersion is achieved in the nozzle, the mixture passes to a mixing tube having a varying cross-section along its length, the varying cross-section creating further turbulence of the mixture passing through the mixing tube, causing further dispersion of the substances within the mixture.
