168F cylinder head, 5.5HP cylinder head, 6.5HP cylinder head
The cylinder head, also known as the cylinder head, is an important part of the engine. It is located in the upper part of the cylinder block, and plays the role of sealing the cylinder and forming the combustion chamber. Due to the high temperature and high pressure gas, the cylinder head bears a huge thermal load and mechanical load. For water-cooled engines, there is usually a cooling water jacket inside the cylinder head to cool high-temperature parts such as the combustion chamber by circulating water.
The 168F cylinder head series has three products, which are 5.5HP cylinder head, 6.5PH cylinder head and 170F cylinder head, and the difference is essentially the capacity.
