Abstract

Problema: En un motor de combustión interna de inyección directa de gasolina, lograr una mejora de la eficiencia de combustible y de la emisión de gases de escape impidiendo o controlando la difusión y separación de la mezcla de aire-combustible debido a estrangulamiento. Medio de solución: Una válvula de inyección de combustible 60 del motor de combustión interna de inyección directa de gasolina inyecta mezcla de aire-combustible de manera que la periferia externa 63a del flujo de inyección 63 caiga a una cavidad 51 de un pistón durante la carrera de compresión. Mediante la cooperación de una zona de estrangulamiento 54 formada en la porción periférica 53 del pistón 5 y una zona de estrangulamiento 43 formada debajo de la superficie de techo 30 de una culata de cilindro 3, que define una cámara de combustión 8, se genera un estrangulamiento oblicuo 20 dirigido hacia arriba, hacia la línea central de inyección en la porción periférica 53 y fluye a lo largo de una porción opuesta 30a de la superficie de techo 30, que está situada hacia arriba del agujero de la cavidad 51 y enfrenta de la misma.
