Abstract

Un motor de flujo unidireccional de tipo U, de dos tiempos, incluye un bloque de cilindros, que forma primeros y segundos cilindros paralelos y una cámara de combustion comun que conecta el primer y segundo cilindros. Primer y segundo pistones se montan para movimiento lineal recíproco dentro del primer y segundo cilindros, respectivamente. El motor también incluye un cigüeñal que tiene un muñon de cigüeñal y una varilla de conexion ahorquillada de una pieza, que conecta cada uno del primer y segundo pistones con el muñon de cigüeñal. La varilla de conexion es flexible y elástica bilateralmente, para permitir variaciones entre una distancia máxima entre el primer y segundo pistones y una distancia mínima entre el primer y segundo pistones y está en un estado relajado a la mitad entre la distancia máxima y la distancia mínima. La pared central tiene una ranura para paso de la varilla de conexion y muescas en ángulo que corresponden a ángulos máximos de la varilla de conexion. La varilla de conexion se diseña para minimizar peso y longitud y el agujero interior del motor y recorrido se eligen, para minimizar la diferencia entre las distancias máxima y mínima del desplazamiento del pasador de piston, a fin de reducir vibraciones e incrementar el rendimiento del motor al mantener alta compresion del cigüeñal.
