<p>The present invention relates to a cylinder head assembly and a clean engine comprising the same and, specifically, to a cylinder head assembly comprising a cylinder head block (100) mounted on the upper part of a cylinder liner, having a combustion chamber through a lower surface, and including a port for inhaling and exhausting and a valve. The cylinder head block (100) includes: an upper floor surface (102); and an upward extended peripheral wall (104) extended upwards from the upper floor surface (102), whose bottom and lateral circumference are blocked with the upper floor surface (102), whose upper part is in the form of an opened bowl, to accommodate a valve drive mechanism having a valve spring (38) inside the bowl, to store lubricating oil of the valve drive mechanism, thereby to block the lubricating oil from flowing down. Moreover, the upper surface (108) of the upward extended peripheral wall (104) is covered with a cylinder head cap (200) for blocking from the outside by covering the upper part of the bowl made of the upward extended peripheral wall (104) while covering the top of the valve drive mechanism inside. The present invention has effects of preventing contamination of an engine structure caused by lubricating oil by preventing the lubricating oil from flowing down if a cylinder head cap is opened during maintenance, and having a simple assembly process and structure without interposing a member such as a middle block between a cylinder head cap and a head cap.</p> |
