摘要： An internal combustion engine has first and second cylinders (12, 14), the first cylinder (12) having a larger swept volume than the second cylinder (14) and the second cylinder being formed in the crown of the first cylinder. First and second pistons (16, 18) are reciprocable respectively in the first and second cylinders (12, 14), the second piston (18) being formed as a protrusion on the crown of the first piston (16). A combustion chamber (20) is formed in the second piston (18) with an air port (44) opening into the first cylinder (12) and a second port (40) opening into the second cylinder (14). A first inlet is provided (25) for supplying air or the like into the first cylinder (12) during an induction stroke of the first piston (16) together with a fuel inlet (36) for supplying fuel to said second cylinder (14). A passage extends between the first and second cylinder to enable transfer of air from said first cylinder (12) to said second cylinder (14) other than through said combustion chamber (20) over a preselected angle of movement of the pistons relative to the cylinders for assisting movement of gases from said second cylinder (14) into said combustion chamber (20). Additional control means for controlling the movement of air is also provided.

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。

摘要： An internal combustion engine has a pair of first and second cylinders (12,14) communicating with a combustion chamber (20) the first cylinder having a larger swept volume than the second cylinder. First and second pistons (16,18) are provided in the cylinders. An inlet port is provided in the first cylinder for delivering a charge of unthrottled fuel while a fuel injector (36) is controlled by a control means (37) to deliver a charge of fuel into the second cylinder (14) as soon as possible after commencement of an induction stroke of the second piston. Movement of the fuel/air mixture from the second cylinder (14) into the combustion chamber (20) is prevented until the second piston (18) is at or near its inner dead center position. The second piston (18) may be formed as a protrusion on the crown of the first piston (16) with the second cylinder (14) being an extension of the first cylinder (12). The engine can be a compression ignition engine in which ignition takes place spontaneously in the combustion chamber, or alternatively a catalyst or hot surface ignition means can be provided in the combustion chamber.
