Abstract

Un método para el arranque de un motor reduciendo el humo blanco y el tiempo entre el arranque y la marcha en vacío. El método incluye lacombinacion de producir dos subinyecciones de combustible en los cilindros del motor de combustioninterna en diferentes puntos en la posicion de rotacion depor lo menos un árbol de levas del motor y reducir a la mitad el numero de cilindros en donde se produce combustion. Las dos subinyecciones de combustiblereducen el tiempo entre elarranque y la marcha en vacío. Una vez que el motor marcha en vacío, el funcionamiento con la mitad de los cilindros reduce elhumo blanco emitido de allí. Las dos subinyecciones de combustible son empleadas también cuando se opera con lamitad de los ci lindros para reducirel ruido.
