Orginal Cylinder Head 080-03100-6273 for HOWO T5G engine Parts. Other cylinder parts also stock in warehouse, waiting for your inquire.

As the top cover of the engine combustion chamber, it seals the top of the cylinder and installs components such as intake/exhaust valves, fuel injectors, and rocker arms; it is responsible for sealing and heat conduction during the compression, combustion, and exhaust processes; and it integrates water/oil channels for cooling and lubricating the engine.

FUNCTION

1. Sealed Combustion Chamber: Serving as the top cover of the engine cylinders, it tightly integrates with the cylinder block and cylinder head gasket (080V03901-0378) to form a closed combustion space. It withstands the high temperature and pressure during combustion, preventing high-pressure gases and combustion products from leaking into the cooling system or crankcase.

2. Installation and Support for Key Components: Includes intake/exhaust valves, valve guides, valve seats, valve springs, rocker arms, and other valve system components; fuel injectors, camshafts, rocker arm supports, etc.; provides intake/exhaust passages.

3. Thermal Management and Cooling: Integrates multi-layer water jackets/cooling channels, circulating coolant to remove combustion heat, preventing cylinder head overheating, deformation, cracking, or cylinder head gasket burning. Provides excellent cooling performance, supporting high-load, long-term operation.

4. Lubrication Support: Built-in oil passages deliver engine oil to friction points such as the camshaft, rocker arms, and valves, achieving lubrication, cooling, and cleaning.

5. Engine Working Cycle: Supports the four strokes: intake, compression, power, and exhaust. The intake valve opens to draw in air/air mixture → compression → fuel injection and combustion → the exhaust valve opens to expel exhaust gas, ensuring stable and efficient power output.

Brief Description of Working Principle

1. Intake Stroke: The piston moves downward, the intake valve opens, and fresh air is introduced into the cylinder head intake manifold.

2. Compression Stroke: The piston moves upward, all valves close, the cylinder head seals the combustion chamber, and the air is compressed and heated.

3. Power Stroke: The fuel injector injects diesel fuel into the cylinder head, the mixture burns to generate high pressure, pushing the piston downward to output power.

4. Exhaust Stroke: The piston moves upward, the exhaust valve opens, and exhaust gases are discharged through the cylinder head exhaust manifold.

DETAILS

Maintenance and Upkeep

1. Regular Inspection: Check the cylinder head exterior for leaks and overheating signs every 50,000-100,000 kilometers; check valve clearance and cylinder head gasket seal during major engine maintenance.

2. Cooling System Maintenance: Keep coolant clean, ensure the water pump/thermostat is functioning properly, and prevent overheating that could cause cylinder head cracks.

3. No Special Maintenance: The cylinder head itself requires no maintenance, but overall engine maintenance indirectly protects its lifespan.

4. Replacement Timing: Replace when cracks, deformation, severe water/air leaks, or during major engine overhaul (it is recommended to replace it along with the cylinder head gasket, bolts, valve guides, etc.).
