Abstract

Se puede utilizar un motor de combustión interna para comprimir gas natural para combustible de vehículos. El motor puede contener una pluralidad de cilindros de compresión de gas, por lo menos un cilindro de combustión estándar para accionar los cilindros de compresión, y un cigüeñal común en un cárter que acopla los cilindros de compresión y al por lo menos un cilindro de combustión estándar. Parte del gas combustible que es comprimido puede fugarse o escaparse por los anillos del pistón de los cilindros de compresión al cárter del motor, lo que representa un problema de seguridad. La presente invención elimina este problema al lavar activamente el cárter a una tasa mayor que la normal.
