The 3086062 Variable Timing Supply Tube, a component manufactured by Cummins, is integral to the operation of heavy-duty trucks, contributing to the efficiency and performance of the engine.

Basic Concepts of Variable Timing Supply Tube

Variable timing systems in diesel engines adjust the timing of valve operations to optimize engine performance and efficiency. These systems work by altering the timing of the intake and exhaust valves, which can enhance power output, improve fuel efficiency, and reduce emissions. The Variable Timing Supply Tube is a key component in this system, facilitating the precise control of oil flow necessary for adjusting valve timing ¹.

Function and Operation

This Cummins part operates within the engine’s variable timing system by regulating the flow of oil to the variable timing actuator. This regulation allows for the dynamic adjustment of valve timing in response to engine operating conditions. By controlling oil pressure and flow, the tube ensures that the actuator can make real-time adjustments to valve timing, which is crucial for maintaining optimal engine performance across a range of operating conditions ².
