Abstract

Se describe una válvula de entrada para un motor de combustión. La válvula de entrada tiene una porción de cabezal que se diseña para mejorar el flujo de la mezcla de aire-combustible alrededor de la porción del cabezal y dentro de la cámara de combustión. La porción del cabezal tiene un borde biselado o redondeado en la superficie superior. Los cambios de ángulo de la superficie de la parte de abajo a la superficie superior son redondos para evitar la separación de la mezcla de aire-combustible de la superficie de la válvula de entrada. Además, la superficie de la parte de abajo de la porción del cabezal tiene una pluralidad de ranuras helicoidales que inducen un flujo circular para mejorar el mezclado de la mezcla de aire-combustible en la cámara. Las ranuras helicoidales también mejoran el intercambio de calor entre la mezcla de aire-combustible y la válvula de entrada.
