Internal combustion engine and oil treatment apparatus for use with the same

An internal combustion engine having an improved oil treatment system. The internal combustion engine may be a splash lubrication engine in which oil is flowed through an oil circulation circuit by a passive pump. In another aspect, a dipstick tube may be provided that includes a portion of the oil circulation circuit. In a further aspect, the internal combustion engine comprises one or more protuberances that automatically penetrate an oil treatment apparatus upon the oil treatment apparatus being mounted to the internal combustion engine, thereby fluidly coupling the oil treatment apparatus to the oil circulation circuit. 本发明涉及种具有改进的油处理系统的内燃引擎。所述内燃引擎可以是飞溅润滑引擎，其中通过被动泵使油流经油循环回路。另方面，可提供包括油循环回路的部分的油尺管。再方面，内燃引擎包括个或多个突起，在油处理装置安装至内燃引擎时，所述突起自动刺穿油处理装置，由此将油处理装置流体地联接至油循环回路。
