Abstract:
Apparatuses, systems and methods are disclosed including an internal combustion engine. The internal combustion engine can include an engine block defining a combustion cylinder and a crankcase, a piston moveable within the combustion cylinder; a cylinder head coupled to the engine block adjacent to and in fluid communication with the combustion cylinder, and a purge system. The purge system can be in fluid communication with the crankcase. The purge system can supply air to the crankcase and to the cylinder head. The purge system can comprise a valve cover coupled to the cylinder head, a breather coupled to the valve cover, and a fumes disposal line coupled with the breather. The fumes disposal line can transport fumes from the breather and away from the cylinder head.
