The camshaft assembly is integral to controlling the timing and operation of engine valves, directly influencing combustion efficiency and power output. Featuring a gear diameter of approximately 259.20 mm, it interfaces precisely with the timing gear set to synchronize valve opening and closing cycles with piston movement. Crafted from high-strength steel, this component endures the mechanical stresses of high RPMs and thermal cycles, maintaining accurate timing over the engine’s lifespan. The robust design ensures smooth rotation, reducing vibration and wear on associated components like the timing gear and followers. Proper installation and maintenance of this assembly are critical for optimal engine performance, fuel efficiency, and emissions compliance.
