Introduction

The Turbo Oil Supply Tube, identified by part number 4941149, is a component manufactured by Cummins, a well-established name in the automotive and heavy-duty truck industry. This tube is integral to the operation of heavy-duty truck engines, particularly those equipped with turbochargers. Its role is to facilitate the delivery of oil to the turbocharger, ensuring that this component remains adequately lubricated and functions efficiently.

Function and Operation

The Turbo Oil Supply Tube operates as a conduit within the engine system, specifically designed to transport oil from the engine’s lubrication system to the turbocharger. This process is vital for the turbocharger’s operation, as it relies on a steady supply of oil for lubrication and cooling. The tube connects to the engine’s oil supply and extends to the turbocharger, where oil is distributed to moving parts, reducing friction and heat ¹.

Purpose of the Turbo Oil Supply Tube

The primary role of the Turbo Oil Supply Tube in a truck’s operation is to maintain the turbocharger’s lubrication and performance. By ensuring a consistent flow of oil, the tube helps to protect the turbocharger from excessive wear and tear, thereby contributing to the engine’s overall efficiency and longevity. Proper lubrication is key to the turbocharger’s ability to compress air entering the engine, which in turn enhances the engine’s power output and fuel efficiency ².

Key Features

The design and construction of the Turbo Oil Supply Tube are tailored to enhance its functionality and durability. Made from high-quality materials, the tube is resistant to the high pressures and temperatures encountered within the engine compartment. Its precise engineering ensures a secure fit within the engine system, minimizing the risk of leaks and ensuring efficient oil delivery. Additionally, the tube’s design allows for easy installation and maintenance, contributing to its overall effectiveness.

Benefits

The Turbo Oil Supply Tube offers several advantages that contribute to improved engine performance and efficiency.
