Abstract

Un motor de tipo de combustión interna o tren motriz que es capaz de quemar una mezcla de combustible de alcohol húmedo e incluye un pistón con movimiento reciprocante dentro de un cilindro unido a una culata y que conecta a un cigüeñal a través de una biela. Una leva y válvula de admisión se montan dentro de un puerto de admisión formado en la culata y una leva y válvula de escape se montan dentro de un puerto de escape también formado en la culata. Un inyector de combustible introduce una fuente de combustible presurizado en el cilindro y el porcentaje de agua en la mezcla de alcohol/agua opera para prolongar la presión del cilindro con el fin de aumentar la presión efectiva media (IMEP), lo que conduce a un mayor torque (Presión Efectiva Media de Freno mejorada - BMEP) del motor a través de un pulso de presión más largo alcanzado durante el período de ventaja mecánica preferida del brazo del cigüeñal del motor.
