Abstract

Un motor (1) de combustión interna está diseñado de modo que el eje central P de un cilindro (4) está desplazado con respecto a una parte (2a) de la chumacera principal de un cigüeñal (2). Una tapa (17) de cojinete está diseñada de manera que el lado hacia el eje central del cilindro de una parte (18) de cojinete principal está fijada a una mampara (7) mediante dos pernas de sujeción (24a, 24c) mientras que el lado lejos del eje central de cilindro desde la parte del cojinete principal está asegurado a la mampara por un perno de sujeción (24b) y que la fuerza que asegura la tapa del cojinete en el lado hacia el eje central del cilindro desde la parte (18) del cojinete principal sea mayor que la fuerza que asegura la tapa de cojinete en el lado lejos del eje central del cilindro.
