Abstract
Una primera carga de combustible con una baja reactividad (índice cetano bajo) es inyectada en un motor rotativo, por ejemplo, un motor Wankel, lo suficientemente pronto durante la carrera de admisión para que una posterior carga de combustible inyectada de reactividad más alta forme una o más zonas de alta reactividad estratificadas dentro de la cámara del motor. La ignición por compresión comienza entonces en las zonas de alta reactividad y se propaga hacia las zonas de reactividad más baja. La apropiada elección de las temporizaciones, las cantidades y otros parámetros de las inyecciones puede permitir el control de la temporización y de la tasa de combustión, de forma que la potencia de trabajo puede potenciarse al máximo, el combustible no quemado puede reducirse al mínimo, y la temperatura de la cámara puede ser controlada para reducir las pérdidas de calor y las emisiones de NOx. Como resultado de ello, se puede potenciar la eficiencia del motor rotativo al tiempo que se reducen las emisiones. Dado que la invención puede ser implementada en un motor rotativo compacto y de peso ligero, está perfectamente indicada para su uso en vehículos híbridos y compactos.
