To create faster and more economical internal combustion engines, I propose to use my invention - Riyanov double slider-crank mechanism. I received 4 patents in Russia (RU2634851C1), China (CN108235713B), Japan (JP6373516B1) and the UK (EP3530879B1) for my invention - Riyanov double slider-crank mechanism (Two-slider crank mechanism), which can be used to create more environmentally friendly and faster engines, generators or in other projects.

SUBSTANCE: crank double-slider mechanism includes a crank, two connecting rods and two sliders. The second connecting rod is connected to the first slider at one end, and to the second slider at the other end. The second connecting rod length is equal to the sum of the double crank length and the distance between the connection point of the second connecting rod with the first slider in the initial phase of its movement measured in the direction of the first slider travel and the longitudinal axis of the second slider.
