The material selection of GAZEL automobile camshafts has many important effects on its performance and durability. Different materials also have obvious differences in dealing with high temperature, high load and other working conditions. The details are as follows:
Common materials and their effects on performance and durability
Medium carbon steel
Performance: Medium carbon steel has certain strength and toughness, relatively low price, and good processing performance. For some ordinary engines in GAZEL cars that do not have extremely high power requirements, camshafts made of medium carbon steel can meet basic power output requirements, and can ensure that the camshaft can stably control the opening and closing of the valves at normal speed and load, and maintain the normal working cycle of the engine.
Durability: After appropriate heat treatment, such as quenching and tempering treatment, its comprehensive mechanical properties can be improved. However, during long-term use, especially under frequent start-stop or certain degree of load change conditions, the medium carbon steel camshaft may experience a certain degree of wear, but through reasonable design and coordination of the lubrication system, it can meet certain vehicle service life requirements.
Alloy structural steel
Performance: Alloy structural steel adds alloy elements such as chromium, molybdenum, and vanadium, which greatly improves the strength, hardness, and wear resistance of the camshaft. In the high-performance engine of GAZEL cars, the use of alloy structural steel camshafts can withstand higher valve spring forces and more complex motion conditions, making the opening and closing of the valves more precise, thereby improving the intake and exhaust efficiency of the engine and enhancing the engine's power performance, such as providing stronger power output during acceleration and high-speed driving.
Durability: Alloy structural steel camshafts have good fatigue resistance and wear resistance. Under high temperature and high load working conditions, they can maintain good dimensional stability and surface integrity, reduce camshaft deformation and wear, and extend the service life of the camshaft. They can adapt to the long-term use of GAZEL cars under various complex road conditions and use conditions.
Ductile iron
Performance: Ductile iron has good casting performance and shock absorption performance, and the cost is relatively low. Its graphite is spherical, which improves the strength and toughness of the material. For some economical engines of GAZEL cars, ductile iron camshafts can reduce production costs while ensuring certain performance. It can smoothly control valve movement at low speed and load, meeting basic needs such as daily urban driving of vehicles.
Durability: After appropriate heat treatment and surface treatment, ductile iron camshafts have certain wear resistance. Under normal use conditions, they can meet the daily use of vehicles and certain mileage requirements, but compared with materials such as alloy structural steel, the durability under extreme conditions such as high load and high speed may be slightly worse.
Differences in the response of different materials to high temperature and high load conditions
Medium carbon steel
Under high temperature environment, the strength and hardness of medium carbon steel will decrease. If the engine is under high load for a long time, it may cause the cam profile of the camshaft to deform and wear more, affecting the normal opening and closing time and lift of the valve, thereby reducing the power performance of the engine, and even engine shaking and power instability.
Alloy structural steel
Alloy structural steel can maintain good thermal stability and strength at high temperature because it contains a variety of alloy elements. Under high-load conditions, its deformation resistance and wear resistance are strong, which can ensure the normal operation of the camshaft, make the opening and closing of the valve accurate, maintain the good performance of the engine under high temperature and high load, reduce engine failures caused by camshaft problems, and improve the reliability and durability of the engine.
Ductile iron
The strength and oxidation resistance of ductile iron at high temperature are relatively weak, and its bearing capacity is limited under high-load conditions. If the engine of the GAZEL car is in a high-temperature and high-load state for a long time, the ductile iron camshaft may have problems such as fatigue cracks and graphite ball degradation, which will affect the performance and service life of the camshaft, resulting in reduced engine efficiency and even possible failure.
Anhui KORBOR Machinery Co., Ltd., as one of the top camshaft manufacturers in China, deeply understands the characteristics and application scenarios of different materials. When manufacturing GAZEL automobile camshafts, the appropriate materials are accurately selected based on the specific performance requirements, usage environment and cost of the GAZEL automobile engine. Advanced heat treatment processes such as tempering, carburizing and quenching are used to further improve the strength, hardness and wear resistance of the camshaft, ensuring that the camshaft can perform well in various complex working environments, providing reliable valve timing guarantee for the GAZEL automobile engine, thereby improving the quality and performance of the entire vehicle.
