摘要： The present invention concerns an engine comprising at least one working cylinder (1) which has valves (16) and/or nozzles for the feed or injection of fuel and air and for the outlet of exhaust gas and a method of operating such an engine. In order to provide an engine and a corresponding method by which the fuel is used considerably more efficiently without excessively high temperatures occurring, which entail the risk of misfires, it is proposed according to the invention that each working cylinder (1) is coupled to a subsequent cylinder (11) which is driven by the pressure of hot exhaust gases from the working cylinder (1) and which is so designed and arranged that on the other hand it feeds pre-compressed combustion air to the working cylinder (1), a cooling device (17) which cools the pre-compressed gas, a device (9, 7) for transferring the cooled pre-compressed gas into the working cylinder (1) and a transfer valve (16) which for a further stroke of the subsequent cylinder (1) transfers exhaust gas under pressure from the working cylinder (1) into the subsequent cylinder (11).

摘要： A four-cycle internal combustion engine has a single or multi-stage pre-cooled compression, which allows the temperature and pressure of intake air to the combustion cylinders to be tightly controlled, so that a much higher compression ratio and pre-ignition compression pressure can be achieved without approaching the air/fuel mixture auto-ignition threshold. The minimal threshold pressure of air intake is determined to be >1.8 Bars at sea level and a minimal temperature drop of at least 50° C. at the heat exchanger air cooling radiator. Because this design can effectively regulate and set the maximum pre-ignition temperature of the fuel-air mixture, it can combust virtually any type of liquid hydrocarbon fuel without knocking. This four-cycle engine, due to its higher compression ratio, generates power equivalent to or greater than a standard four-cycle engine in a smaller and lighter engine and at a higher efficiency.
摘要翻译：四循环内燃机具有单级或多级预冷压缩，这允许对燃烧气缸的进气的温度和压力进行严格控制，使得高得多的压缩比和预点火压缩压力可以在不接近空气/燃料混合物自动点火阈值的情况下实现。在热交换器空气冷却散热器处，空气入口的最小临界压力被确定为海平面以上> 1.8Bars和至少50℃的最小温度降。因为这种设计可以有效地调节和设定燃油混合物的最高预燃温度，所以它几乎可以燃烧任何类型的液体碳氢化合物燃料，而不会发生爆震。这种四冲程发动机由于其较高的压缩比，在更小且更轻的发动机中以更高的效率产生等于或大于标准四冲程发动机的功率。
