In the South American motorcycle market, what are the differences in the performance requirements of camshafts for different types of motorcycles (such as off-road, street cars, and scooters)?
Off-road motorcycles
High torque and explosive power: South America has diverse terrains, and off-road motorcycles often need to deal with complex terrains such as steep slopes and muddy roads. This requires the engine to output strong torque at low speeds and burst power instantly. Anhui KORBOR Machinery Co., Ltd. needs to design a special cam profile so that the valve can open quickly and significantly at low speeds, allowing more air-fuel mixture to enter the cylinder for efficient combustion. For example, a larger cam lift and a suitable valve overlap angle are used to optimize the intake and exhaust efficiency at low speeds to meet the needs of instant acceleration and climbing during off-road riding.
Excellent durability: The off-road riding environment is harsh, the engine is under high load for a long time, and the camshaft is subjected to great pressure and friction. Anhui KORBOR Machinery Co., Ltd. further enhances the strength, hardness and wear resistance of the camshaft by selecting high-performance alloys and heat treatment processes such as tempering, carburizing, and quenching. For example, appropriately increase the thickness of the carburized layer and improve the surface hardness of the camshaft to ensure that the camshaft is not easy to wear and deform under extreme conditions, and extend its service life.
Rapid response capability: During off-road driving, drivers frequently change gears and speeds, and the engine operating conditions change rapidly. The camshaft must have rapid response performance and accurately control the timing of valve opening and closing. The company can optimize the manufacturing accuracy and mass distribution of the camshaft, reduce the moment of inertia, enable the camshaft to quickly respond to changes in engine speed, achieve precise control of the valve, and improve the dynamic performance of the engine.
Street car
Medium and high speed power output: On urban roads in South America, street cars need to show good power in the medium and high speed range to meet the needs of overtaking and fast driving. Anhui KORBOR Machinery Co., Ltd. can design camshafts so that the valves are open longer and have a larger lift at medium and high speeds, ensuring sufficient intake and exhaust volume and improving combustion efficiency. For example, with a progressive cam profile design, as the speed increases, the valve lift and opening time are gradually optimized, allowing the engine to output strong power at medium and high speeds.
Operation stability: Street cars focus on riding comfort, and the camshaft must operate smoothly to reduce vibration and noise caused by valve movement. With advanced manufacturing technology, the company ensures high-precision processing of the camshaft, making the cam surface smooth and the phase between each cam accurate. At the same time, through dynamic balancing test and correction, the camshaft is ensured to remain stable at high speed rotation, providing riders with a quiet and comfortable riding experience.
Lightweight and high efficiency: In order to improve the handling performance and fuel economy of street cars, lightweight camshafts are very important. Anhui KORBOR Machinery Co., Ltd., on the premise of ensuring the strength and performance of the camshaft, takes advantage of the material, such as the selection of high-strength, low-density alloy materials, or optimizes the structural design, and uses hollow shafts to reduce weight. This can reduce the overall mass of the engine without affecting the reliability and power transmission efficiency of the camshaft.
Scooter
Low-speed torque and economy: Scooters are mainly used for daily commuting in cities, and torque output at low speeds is crucial to achieve easy starting and low-speed driving. Anhui KORBOR Machinery Co., Ltd. When designing the camshaft, it is necessary to optimize the valve opening and closing time and lift to ensure that the engine can effectively inhale and compress the mixture at low speed and output sufficient torque. At the same time, by accurately controlling the valve action, the combustion efficiency is improved, fuel consumption is reduced, and the economic needs of scooter users are met.
Quietness and comfort: The riding space of scooters is relatively closed, and the noise control requirements are high. The noise generated by the operation of the camshaft will directly affect the riding experience. The company can reduce the friction noise between the cam and the valve tappet through fine surface treatment technology, optimize the lubrication design of the camshaft, and reduce the friction and impact between components. In addition, the structure of the camshaft is reasonably designed to reduce its vibration transmission and create a quiet and comfortable riding environment.
High reliability and long life: Scooter users usually want the vehicle to be stable and reliable and reduce the frequency of maintenance. Anhui KORBOR Machinery Co., Ltd. relies on high-performance alloy materials and mature heat treatment technology to ensure the stable performance of the camshaft during long-term use. Strict quality inspection process, multiple inspection steps from raw materials to finished products, ensures that each camshaft has high reliability and long life, meeting the expectations of scooter users for product durability.
