4D95 Diesel Engine Cylinder Head
The 4D95 Diesel Engine Cylinder Head is a crucial component in the 4D95 engine, which is commonly used in various industrial and construction equipment. The cylinder head is an integral part of the engine's combustion chamber and is responsible for several key functions
Features and functions of 4D95 Diesel Engine Cylinder Head:
-
Combustion Chamber: The cylinder head forms the upper part of the engine's combustion chamber, where the air-fuel mixture is compressed and ignited to generate power.
-
Valve Seats and Ports: The cylinder head contains valve seats and ports for the intake and exhaust valves. These components control the flow of air into the cylinder and the expulsion of exhaust gases.
-
Cylinder Bore: The cylinder head is positioned above the engine's cylinders and features a machined surface for a proper seal with the engine block and the cylinder liners.
-
Coolant Passages: The cylinder head includes passages for the circulation of engine coolant to maintain optimal operating temperatures.
-
Oil Passages: It also has oil passages for the lubrication of critical components within the head, including the camshaft and valve train.
-
Valvetrain Components: The cylinder head houses various valvetrain components, including the camshaft, lifters, rocker arms, and pushrods. These components are responsible for operating the intake and exhaust valves.
-
Heat Dissipation: The cylinder head is designed to dissipate heat generated during combustion to prevent overheating and maintain the proper temperature within the engine.
-
Sealing Surfaces: The cylinder head must provide an airtight seal to maintain compression within the cylinder and prevent the escape of combustion gases.

The cylinder head of the 4D95 diesel engine is made from high-strength cast iron, which provides excellent wear-resistance and can withstand high temperatures and pressures. It features precise holes that connect with other engine components, ensuring efficient and stable operation. The material is of top quality, making it highly durable and resistant to corrosion.
Exquisite Process Technology Improve Engine’s Performance and Reliability:
The cylinder head is manufactured using high-precision machining techniques to ensure its dimensional accuracy and surface finish. This meticulous process guarantees that the cylinder head fits perfectly and operates smoothly, improving the engine’s performance and reliability. The precise machining of the cylinder head also ensures that it seals tightly, preventing any gas or liquid leakage and ensuring the engine runs smoothly. With its high-precision manufacturing, the cylinder head is built to last and will keep your engine running smoothly for years to come.
Excellent Corrosion Resistance:
The cylinder head is made of high-quality materials that have excellent corrosion resistance. This ensures that the cylinder head can withstand the corrosive effects of various media, thereby extending the engine’s service life. The high-quality materials used in the cylinder head also provide excellent strength and durability, ensuring that the engine can withstand the rigors of daily use. The corrosion-resistant properties of the cylinder head are particularly important in harsh environments where the engine is exposed to corrosive substances such as saltwater or acidic gases. With its superior corrosion resistance, the cylinder head can withstand these harsh conditions and continue to perform reliably for years to come.
FAQ:
Q1: What kind of products do you produce?
Re: We mainly produce the engine parts, like piston, piston ring, cylinder liner, engine valve, engine guide, head gasket, full gasket set, etc..
Q2: Do you support OEM or ODM?
Re: We support.
Q3: Can I purchase with only 1 sample?
Re: You can do that if the products that you need is in stock.
Product Function:
The main task of the cylinder head is to close the combustion chamber of the engine from the top. The upper part of the engine is called the cylinder head, while the lower part is the engine block. The cylinder head sits on the engine and closes off the combustion chamber. The gap that remains between the cylinder head and the engine is completed by the head gasket.
Another task of the cylinder head is to ensure the constant lubrication of the cylinder. If the cylinders are not well-oiled, a smooth operation of the engine is not possible, which is why the cylinder head is an
indispensable part of the function of the engine.
This is how a cylinder head is built
The cylinder head is not only a very important part of your engine, but also one of the most expensive parts of the vehicle's engine due to its complex structure. Since the cylinder head is exposed to very high temperatures during the combustion process, it consists of resistant aluminum alloys and light metals.
At the bottom, it is usually anchored directly to the crankshaft housing and closed at the top with a valve cover. Depending on whether your vehicle has a diesel or gasoline engine, the structure of the cylinder head differs.
Product Types:
A cylinder head in a gasoline engine
1.Inlet and exhaust ducts: These ensure that the exhaust gas can escape from the cylinders and the absorbed air-fuel mixture can get into the cylinders
2.Inlet and exhaust valves: This is where petrol engines suck an air-fuel mixture in, while exhaust gases are simultaneously transported to the exhaust system
3.Camshafts: A crankshaft driven by the timing belt drives the camshafts. The camshafts are responsible for opening and closing the valves
4.Injectors: They ensure that the fuel is injected into the combustion chambers
5.Spark plugs: They initiate the combustion of the fuel
A cylinder head in a diesel engine
1.Inlet and exhaust ducts: They allow exhaust gas to escape from the cylinders and allow the captured air-fuel mixture to enter the cylinders
2.Inlet and exhaust valves: Diesel vehicles suck air in through the inlet and exhaust valves while exhaust gases are simultaneously transported to the exhaust system
3.Camshafts: A crankshaft driven by the timing chain drives the camshafts. The camshafts are responsible for opening and closing the valves
4.Injectors: These inject the fuel in diesel engines into the combustion chambers or antechambers
5.Glow plugs: They act as a cold-start aid
Can the cylinder head get any defects?
Unfortunately, the complex structure of the cylinder head and its numerous tasks make it prone to defects. The most common defect is a leaking cylinder head gasket, which is caused by an increased abrasion. See more in our blog post on the signs of a defective head gasket.
There can also be defects on the cylinder head itself, for example, by the high temperatures and strong vibrations in a running engine. This can lead to cracks in the material of the cylinder head.
