Problems solved by technology
[0003] In order to overcome the insufficient expansion of Diesel cycle and Otto cycle and the low average effective pressure of Atkinson cycle expansion, the invention provides a method for changing the piston stroke. The method can not only make the Otto cycle, Diesel cycle The expansion is sufficient, and at the same time, the expansion mean effective pressure of the Atkinson cycle is not lower than that of the Otto cycle and Diesel cycle

Embodiment Construction
[0019] exist figure 2 In the embodiment shown, the floating sleeve shaft (1) of the eccentric group, the connecting rod journal (5) of the crankshaft, the connecting rod (3), and the connecting rod (4) are respectively connected by clearance and dynamic fit. The ratio is better, the engine supercharging ratio is better, the diesel cycle is better with PT fuel injection system, the piston arrangement is any way, and the function of the eccentric group floating sleeve shaft can also be controlled by the crankshaft at a lower compression ratio. The connecting rod journal position installs a "crankshaft" instead.

Description
Technical field [0001] The invention relates to a method for changing the dead center position of a piston, in particular to an improved method for Otto cycle, Diesel cycle and Atkinson cycle which can reduce fuel consumption and improve the dynamic performance of an internal combustion engine. Background technique [0002] The currently used reciprocating four-stroke internal combustion engine works according to the Otto cycle and the Diesel cycle. The disadvantage is that the compression ratio is equal to the expansion ratio, and the gas cannot expand more. Therefore, there have been cases where the expansion ratio is greater than the compression ratio. Atkinson cycle, but the mean effective pressure of expansion is low, and the gain of work is not greater than the loss. SUMMARY OF THE INVENTION [0003] In order to overcome the insufficient expansion of the Diesel cycle and the Otto cycle and the low average effective pressure of the Atkinson cycle expansion, the invent...
