Abstract
La invención trata de un motor de dos tiempos con dos válvulas rotativas, en forma de discos (1), una a cada lado del cárter (2), y cuyos platos están cortados a 160 grados (1). Las válvulas rotativas poseen tapas adicionales (5) que tienen un grosor que permiten realizarles orificios, en la parte superior de la tapa (6), que conectan en la parte superior con el conducto que va al carburador, y en la parte inferior esta simétricamente alineado con la lumbrera de admisión (4). Esto permite conectar dos lumbreras de admisión con un carburador y controlar la entrada de aire y combustible al cárter del motor, haciendo que las lumbreras de admisión permanezcan abiertas por más tiempo en la carrera ascendente del pistón, esto aumenta la cantidad de mezcla de aire y combustible que entra al cárter.The invention deals with a two-stroke engine with two rotary valves, in the form of discs (1), one on each side of the crankcase (2), and whose plates are cut at 160 degrees (1). The rotary valves have additional covers (5) that are thick enough to allow holes to be made in the upper part of the cover (6), which connect at the top with the duct that goes to the carburetor, and at the bottom is symmetrically aligned with the intake port (4). This allows two intake ports to be connected to one carburetor and control the intake of air and fuel into the crankcase by causing the intake ports to remain open longer on the upstroke of the piston, this increases the amount of air and fuel mixture. fuel entering the crankcase.
