    摘要： A split-cycle engine includes a compression cylinder having a first volume for a first working fluid and a second volume for a second working fluid, the first volume and second volume being separated by the compression piston, an expansion cylinder having a first volume for the first working fluid and a second volume for the second working fluid, the first volume and second volume being separated by the expansion piston, and a fluid coupling between the second volume of the compression cylinder and the second volume of the expansion cylinder, wherein the two second volumes and the fluid coupling provide a closed volume for the second working fluid, wherein the fluid coupling includes a regenerator arranged such that the two second volumes are thermally decoupled.

    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.

    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.
