Abstract

La presente invención se refiere a un motor de combustión interna, que comprende un cilindro; una cabeza de cilindro situada en un extremo del cilindro, un pistón montado para el movimiento recíproco dentro del cilindro, una cavidad en la cabeza del cilindro; una boquilla de inyección de combustible ubicada en la cavidad de la cabeza del cilindro para entregar el combustible en la cavidad en una dirección hacia el pistón; el pistón tiene una cara superior dirigida hacia la cabeza del cilindro, caracterizado porque comprende un tazón en la cara superior del pistón, posicionado de tal manera que a través de cuando menos una mitad final de la carrera de compresión del pistón, el tazón se encuentra en una trayectoria de entrega del combustible desde la boquilla, de tal manera que el combustible será depositado dentro del tazón; y un aro que se extiende alrededor de la periferia del tazón, que se proyecta hacia arriba desde la superficie superior del pistón, en donde, una superficie periférica externa del aro está inclinada hacia arriba y hacia adentro en un ángulo comprendido entre 30 a 50 grados en relación al eje del tazón.
