The cylinder head subassembly is one of the key components of the engine, and its main functions include:
1. Install the intake and exhaust components, such as the intake and exhaust valve seats, valve guide holes, etc., which are used to install the intake and exhaust valves, as well as the intake and exhaust channels. 2. For gasoline engines, there are holes for installing spark plugs on the cylinder head; for diesel engines, there are holes for installing injectors on the cylinder head. The cylinder head of an overhead camshaft engine also has camshaft bearing holes for installing the camshaft. 3. The cylinder head is generally made of gray cast iron or alloy cast iron. Aluminum alloy has good thermal conductivity, which is beneficial to improving the compression ratio. 4. The cylinder head is a component of the combustion chamber. The shape of the combustion chamber has a great influence on the operation of the engine. The combustion chambers of gasoline and diesel engines are mainly located on the cylinder head and in the pit on the top of the piston.
Through these functions, the cylinder head sub-assembly ensures the normal and efficient operation of the engine. Specializing in Toyota auto parts, you can consult and ask for price WhatsApp:+86 18814056348 WeChat:+86 18814056348
