Abstract: 【課題】本発明者が出願した「内燃機関の点火機構」(特願2012−276596)に使用することが出来るカム機構として「立ち上がりが急峻なカム機構」(特願2013−28576)を出願したが、この性能を更に向上させたものを開発することをその課題とした。【解決手段】同じカムリフトに対してカムの回転速度を大きくすれば、回転角が大きくなり相対的に圧力角を小さくすることが出来ることになる。この関係を利用して基本カムの整数倍で回転する高速カムを用いて圧力角を小さくし、さらには「立ち上がりが急峻なカム機構」に記した対称カムと組み合わせる方法によって、より急峻な立ち上がりをすることが出来る高速カム機構を実現した。【選択図】図1

Abstract: In a cylinder lubrication system for a two-stroke engine, a plurality of lubricating oil supply openings (78) open out in the inner circumferential surface of the cylinder (42) at a point lower than a top ring (22b) of a piston (22) located at a bottom dead center. The lubricating oil supply openings are configured to provide a larger amount of lubricating oil in the thrust side and anti-thrust side of the cylinder than in a remaining part of the cylinder. Thereby, the consumption of lubricating oil and the emission of undesired substances can be minimized while providing an optimum lubrication of the sliding part between the piston and the cylinder.

Abstract: Fluid working reciprocating devices are described, including internal combustion engines, compressors and pumps, and how such devices may transfer power to electric generators or turbines. Devices can be within casings which may be “snapped into” larger machinery, such as vehicles, aircraft or marine craft. A number of arrangements for pistons and cylinders of unconventional configuration are described, mostly intended for use in IC engines operating without cooling. Included are toroidal combustion or working chambers, some with fluid flow through the core of the toroid, a single piston reciprocating between a pair of working chambers, tensile valve actuation, tensile links between piston and crankshaft, energy absorbing piston—crank links, crankshafts supported on gas bearings, cylinders rotating in housings, injectors having components which reciprocate or rotate during fuel delivery. In some embodiments pistons may rotate while reciprocating. High temperature exhaust emissions systems are described, including those containing filamentary material.
