Abstract

Motor de combustión con inyección directa, con una cámara de combustión que está configurada entre la parte inferior de la culata, la parte superior del pistón, y en el resto por la superficie de deslizamiento del cilindro, con dos canales de admisión de aire con válvulas, con un canal de escape de aire con una válvula, así como con dos bujías de encendido, caracterizado porque una sección aproximadamente lineal de los canales de admisión de aire, situada corriente arriba del flujo, tiene una inclinación Teta 2 respecto al eje del pistón, inclinación que es mayor que la inclinación Teta 1 del inyector respecto al eje del pistón.
