Abstract

Un motor de piston de dos tiempos de auto encendido controlado o de encendido por chispa, alimentado por mezcla homogénea de aire combustible, con barrido por carter, donde la mezcla que se transfiere desde el carter hacia el cilindro no supera el 50% del volumen del mismo, dicho motor posee válvulas de laminas en los canales de transferencia que comunican el carter con el cilindro para controlar la dinámica interna de la mezcla aire combustible, limitando el flujo máximo instantáneo que se transfiere hacia el cilindro para lograr mejor nivel de estratificacion entre la mezcla aire combustible y los gases residuales de escape lográndose así la activacion termoquímica de parte del combustible contenido en la mezcla. Dicho motor posee también una válvula rotativa adyacente a la lumbrera de escape del cilindro que gira en sincronismo con el cigüenal la cual cierra la lumbrera de escape pocos grados después que el piston alcanza el punto muerto inferior, evitando así la fuga de mezcla termoquimicamente activada y reteniendo parte de los gases quemados dentro del cilindro. Luego durante la carrera de compresion se aporta mas calor a la mezcla termoquimicamente activada descomponiéndose parte del combustible contenido en la misma en radicales activados los cuales en la cercanía del punto muerto superior actuan como ignitores encendiendo la mezcla en forma simultánea y completa, obteniéndose así muy bajos niveles de emision de CO, HC, Nox como así también bajo consumo de combustible y aceite.
