Abstract: The invention relates to a connecting rod/crank transmission system in which the force (F1) applied by the connecting rod is transmitted via a pin (1) to two diverging arms (7, 8) of the crank that are joined to the counterweight (3) thereof at points (C, D) located at a radial distance (r2) greater than the radial distance (r2) of the connecting rod pin (1), in order to increase the torque transmitted and the performance of the system. The invention also relates to a crankshaft formed with said cranks.

Abstract: The invention of the present application provides a method and a device to optimize the combustion of a liquid fuel by means of gasification of said fuel. Gasification of liquid fuel through the method and the device of the present invention is achieved by atomizing liquid fuel that is converted in very fine liquid particles, and wherein the atomization of said very fine liquid particles is done in a closed camera of an adequate volume, and wherein in said closed camera a vacuum has been generated, and wherein in said closed camera there is an adequate flow, and wherein the adequate flow is achieved by means of a flow control mechanism, and wherein the very fine liquid particles, due to the effect of the vacuum, to the proper environment generated by the existence of an adequate volume of the camera, and the adequate flow, are gasified without need of increasing temperature, nor using any mechanical mean inside the camera.
