The exhaust camshaft is a critical component in modern engines, controlling the timing of exhaust valve opening and closing to optimize combustion efficiency, power output, and emissions. High-quality camshafts enhance engine performance, reduce fuel consumption, and prolong service life.
Hebei Oujia Import And Export Trade Co., Ltd. specializes in high-precision camshaft solutions for passenger cars, commercial vehicles, and light trucks. We supply OEM and aftermarket camshafts, including complete camshaft intake and exhaust assemblies, individual cam components, and replacement parts. Our camshafts are made from high-strength steel alloys, precision-machined, and heat-treated to resist wear, maintain dimensional stability, and operate reliably under high-temperature conditions.
Oujia’s exhaust camshaft is manufactured with high-carbon steel alloys and advanced nitriding treatments. These camshafts withstand high-pressure exhaust cycles and maintain precise valve timing under extreme operating conditions.
Key advantages of Oujia exhaust camshafts include:
Optimized valve lift and duration for maximum power output
Reduced engine knock and vibration
Increased durability in both gasoline and diesel engines
Maintenance involves periodic inspection for wear, scoring, or pitting. Proper lubrication and timely replacement of camshaft bearings ensure long-term engine reliability.
The 13020 1N521 is an OEM camshaft commonly used in Mitsubishi B-series engines and similar designs. Oujia manufactures this camshaft using premium forged steel, precision-ground for optimal profile consistency.
Advantages of the 13020 1N521 camshaft include:
Accurate valve timing and smooth operation
High wear resistance and thermal stability
Compatibility with OEM components and assemblies
These camshafts are suitable for engine rebuilds, OEM replacement, or performance upgrades. Installation guidance includes torque specifications, proper bearing lubrication, and alignment verification to maintain peak performance.
The cam exhaust profile significantly influences engine efficiency, emission control, and turbocharger performance. Oujia cam exhaust components are precision-machined and heat-treated to maintain:
Consistent lift, duration, and valve timing
Efficient exhaust gas expulsion
Reduced backpressure and improved combustion
For engines with forced induction, proper cam exhaust profiles improve turbocharger response, engine torque, and power delivery. Regular inspection and adjustment of cam exhaust profiles ensure long-term reliability.
Oujia provides complete camshaft intake and exhaust assemblies for various engine types. Assemblies include:
Intake and exhaust camshafts
Camshaft gears and sprockets
Timing belts or chains
Camshaft bearings, seals, and hardware
These assemblies are tested for alignment, torque, and vibration before shipment to ensure reliable operation. Using a complete Oujia assembly reduces installation errors and ensures OEM-level performance in both gasoline and diesel engines.
Oujia selects materials and treatments for camshafts to ensure strength, durability, and thermal resistance. Common material features include:
High-carbon steel or alloy steel for tensile strength
Nitriding treatment for surface hardness and wear resistance
Heat-treated lobes and journals to prevent deformation under high RPM
Precision grinding for smooth cam profiles and optimal valve actuation
The combination of material and treatment ensures consistent performance in high-load, high-temperature environments, extending the service life of camshafts and engine assemblies.
Proper installation and maintenance are critical for camshaft intake and exhaust systems:
Verify camshaft alignment and timing marks during assembly.
Apply high-quality engine oil to cam lobes and bearings before initial operation.
Check valve clearances and adjust as recommended by OEM specifications.
Inspect camshaft bearings and journals for wear periodically.
Replace gaskets and seals during rebuilds to prevent leaks.
Following these steps ensures smooth engine operation, reduced wear, and optimal performance of both intake and exhaust camshafts.
