摘要： A reciprocating compressor. A hollow cylinder tube contains a piston assembly having two pistons connected by a piston rod. At each end of the cylinder tube is an outer chamber between an end plate and an outer end of the proximate piston. These two outer chambers and the outer ends of the pistons define a power cylinder at each end of the cylinder tube. In the mid-portion of the cylinder tube, a center divider is situated between the pistons and has an aperture that allows the piston rod to reciprocate through it. The two inner chambers formed thereby and the inner ends of the pistons define two compression cylinders in the mid-portion of the cylinder tube. The two compression chambers share a suction manifold and a discharge manifold, but have independently operating suction and discharge valves.

摘要： A two-stroke internal combustion engine is disclosed having opposed cylinders, each cylinder having a pair of opposed pistons, with all the pistons connected to a common central crankshaft. The inboard pistons of each cylinder are connected to the crankshaft with pushrods and the outboard pistons are connected to the crankshaft with pullrods. Each opposed cylinder further comprises an integrated scavenge pump for providing positive intake pressure. This configuration results in a compact engine with a very low profile, in which the free mass forces can be substantially balanced. The engine configuration also allows for asymmetrical timing of the intake and exhaust ports through angular positioning of the journals on the crankshaft.

摘要： A free piston engine is configured with a pair of opposed engine cylinders located on opposite sides of a fluid pumping assembly. An inner piston assembly includes a pair of inner pistons, one each operatively located in a respective one of the engine cylinders, with a push rod connected between the inner pistons. The push rod extends through an inner pumping chamber in the fluid pumping assembly and forms a fluid plunger within this chamber. An outer piston assembly includes a pair of pistons, one each operatively located in a respective one of the engine cylinders, with at least one pull rod connected between the outer pistons. The pull rod extends through an outer pumping chamber in the fluid pumping assembly and forms a fluid plunger within this chamber. Each outer piston cooperates with an integrated scavenge pump in order to compress the charge air, thus significantly increasing the air charge density into the engine cylinders for each stroke of the engine.

摘要： A catalytic internal combustion engine has an air cylinder (12) and a fuel management cylinder (14) interconnected at their head ends by a combustion chamber (5) and having respective pistons (16, 18) reciprocating in phase. Petrol is injected into the fuel management cylinder where is vaporizes in air during the compression stroke to form a very high air/fuel vapor mixture which cannot be spontaneously ignited by the high compression pressures used in the engine. Low octane petrol is a suitable fuel even when compression ratios of 12-16:1 are used. Air from cylinder (12) is forced into the combustion chamber (5) during the compression stroke through a port (44) which imparts a vortex motion in the air in the chamber (5). This mixes with the fuel/air mixture entering the combustion chamber from cylinder (14). A thin platinum layer catalyst on the wall of the combustion chamber triggers compression ignition of the fuel/air mixture as it mixes with the air in the combustion chamber. The continuous ignition produced by the catalyst as fuel molecules contact it results in complete combustion of the fuel/air mixture. Since the catalyst is capable of igniting very lean fuel/air mixtures which cannot be spark ignited considerable fuel economy is achieved with complete combustion and low exhaust emission, obviating the need for catalytic after burners in the exhaust system.
摘要翻译：催化内燃机具有气缸（12）和燃料管理筒（14），燃料管理筒（14）在其头端处由燃烧室（5）互相连接并具有相位往复运动的相应的活塞（16,18）。汽油被注入到燃料管理缸中，在压缩行程中在空气中蒸发，形成非常高的空气/燃料蒸汽混合物，其不能被发动机中使用的高压缩压力自发地点燃。即使使用12-16：1的压缩比，低辛烷值汽油也是合适的燃料。在压缩行程期间，来自气缸（12）的空气通过端口（44）被迫进入燃烧室（5），该端口在室（5）中的空气中产生涡旋运动。这与从气缸（14）进入燃烧室的燃料/空气混合物混合。在燃烧室壁上的薄铂层催化剂在燃料/空气混合物与燃烧室中的空气混合时触发燃料/空气混合物的压燃。作为燃料分子接触的催化剂产生的连续点火导致燃料/空气混合物的完全燃烧。由于催化剂能够点燃不能被火花点燃的非常贫的燃料/空气混合物，因此在完全燃烧和低废气排放的情况下实现了相当大的燃料经济性，从而避免了在排气系统中的燃烧器之后催化的需要。
