摘要： By the utilizing of a slave cylinder working in coordination with a master cylinder, the slave cylinder both receives cool atmospheric air and receives hot, partially un-burnt exhaust gases from the master cylinder to create a second power-stroke in the slave cylinder. With the two coordinating cylinders, the entire working process is from 0 to 810 degrees of revolution crankshaft. The master cylinder cycles work from 0 to 720 degrees of revolution and slave cylinder cycles work from 90 to 810 degrees of revolution. The master cylinder begins to intake air and fuel at 0 degree of revolution and slave cylinder begins to intake air at 90 degrees of revolution. There is an angle of 60-120 degrees differences between master and slave cylinder, where the slave cylinder is trailing the master.

摘要： The modification of the exhaust valve of a two cycle diesel engine in order to increase the amount of the valve stem travel and hence larger annular opening, without changing the total time period or degrees of crank shaft rotation during which time the exhaust valve is open and permits the combusted fuel air mixture to exhaust is disclosed. In cooperation with the improved valve opening, the intake port for the intake air is lowered and lengthened to therefore permit a longer power stroke, and the input of more air which, when combined with the improved scavenging, increases the amount of oxygen available for combustion. The increase in the opening of the valve is achieved by shortening one of the two arms of the rocker arm which engages the valve stem, the arm shortened being the arm which is activated by the push rod. This results in a lengthening of the stroke of the valve stem and the valve which translates into a larger annular opening for exhaust. In addition, the exhaust sector of the 180.degree. of the power stroke is delayed by retarding the exhaust valve cam shaft to a point where the piston is further down the cylinder, and the air intake port is similarly lowered. Finally, in combination with the foregoing, the crank shaft throw is extended, while the connecting rod is shortened somewhat in order to increase the travel of the power stroke by approximately 5%. The fuel injection-timing remains essentially the same as with the original style engine. In order to avoid seriously increasing the compression ratio of about 17:1, the piston is modified to a desirably modified domed configuration.
摘要翻译：改进两循环柴油发动机的排气阀，以增加阀杆行程的数量，从而增加环形开口的大小，而不改变排气阀打开期间曲轴转动的总时间或程度; 公开了燃烧的燃料空气混合物排气。与改进的阀门开口配合，吸入口的进气口被降低并延长，从而允许更长的动力行程，并且输入更多的空气，当与改进的清除相结合时，可增加可用于燃烧的氧气的量。阀的开度的增加通过缩短与阀杆接合的摇臂的两个臂中的一个来实现，该臂缩短为由推杆启动的臂。这导致阀杆和阀的行程的延长，其转换成用于排气的较大的环形开口。此外，通过将排气阀凸轮轴延迟到活塞进一步向下向下的点，动力行程的180度的排气扇段被延迟，并且进气口也同样降低。最后，与上述相结合，曲柄轴的延伸延伸，同时连杆稍微缩短，以便将动力冲程的行程增加约5％。燃油喷射时间与原始风格的发动机基本保持一致。为了避免严重地增加约17:1的压缩比，将活塞修改为理想的改进的圆顶形状。

摘要： An engine including at least two piston and cylinder assemblies that, when operating with a fuel savings cycle, establish at the end of the simultaneous compression strokes a charge of compressed air in one cylinder of one assembly and a charge of compressed air fuel mixture in the other cylinder of the other assembly. When the air fuel mixture is ignited, the high pressure conditions in the other cylinder are immediately communicated through a passage to the one cylinder to accomplish a double expansion during the simultaneous power drive strokes thus using much of the pressure energy before exhaust occurs by the pistons themselves. The improvement comprises changing the other assembly which has the charge of compressed air fuel mixture therein between the two piston and cylinder assemblies in a predetermined pattern as, for example, an operative alternation between the two piston and cylinder assembles.

摘要： Valve assembly and method in which a valve member is connected to an elongated lever arm for controlling communication between two chambers in an engine. The valve assembly is disposed at least partially within one of the chambers, and the valve member is moved between open and closed by an actuator connected to the lever arm. In some disclosed embodiments, a pilot valve is opened to equalize pressure on both sides of the valve member prior to moving the valve member toward the open position. In others, where a piston in an expansion cylinder is driven by hot, expanding gases from a separate combustion chamber or heat exchanger, the exhaust valve is closed before the piston has completed its exhaust stroke, and pressure is allowed to build up in the expansion cylinder to a level corresponding to the pressure in the combustion chamber before the valve member is moved toward the open position.

摘要： A piston compound internal combustion engine is disclosed with an expander piston deactivation feature. A piston internal combustion engine is compounded with a secondary expander piston, where the expander piston extracts energy from the exhaust gases being expelled from the primary power pistons. The secondary expander piston can be deactivated and immobilized, or its stroke can be reduced, under low load conditions in order to reduce parasitic losses and over-expansion. Two mechanizations are disclosed for the secondary expander piston's coupling with the power pistons and crankshaft. Control strategies for activation and deactivation of the secondary expander piston are also disclosed. In addition, six-cylinder engine configurations are defined by replicating groups of two power pistons and one expander piston.

摘要： The present invention provides a coordination pressure management system for raising the maximum operational range of the eight-stroke engine; said coordination pressure management system includes a real-time control system for adjusting the phase-difference between the master piston and the slave piston according to the combustion condition of the master cylinder and the compression condition of the slave cylinder, so that the maximum compression pressure of the slave-compression-process is regulated within the range of 75% to 25% of the concurrent maximum combustion pressure of the master cylinder, thereby maintaining a high coordination-efficiency in any operational load and rpm condition.In addition the coordination pressure management system is able to provide a flow of high-density-air at controlled temperature in the heavy load operation, which ensures a stable cooling effect to the hot-combustion-medium of the master cylinder, so that the overall temperature of the master cylinder can be reduced in the heavy load operation for better durability and higher fuel efficiency.
