As a key component of the camshaft phaser, the eccentric shaft gear 06B109088D works closely with the engine management system. Based on signals from the crankshaft position sensor and camshaft position sensor, the engine management system performs precise calculations to control the oil pressure control valve, adjusting the oil pressure supplied to the phaser. Changes in oil pressure drive the internal structure of the phaser, subtly altering the phase of the camshaft relative to the timing sprocket. During engine cold start, it advances the intake valve opening timing to draw in more fresh air, promoting better atomization and combustion of the air-fuel mixture for smooth startup. Under high-load operation, it delays the intake valve closing timing to increase air intake, enhancing power output—ensuring the engine maintains optimal valve opening/closing timing across all operating conditions.
2. Combustion Process Optimization
Through precise valve timing control, the 06B109088D plays a critical role in optimizing in-cylinder combustion. During the intake stroke, it ensures the intake valve opens at the optimal timing with the right lift, allowing air to enter the cylinder at an ideal flow rate and angle, where it fully mixes with fuel injected by the injector to form a uniform, properly proportioned combustible mixture. In the compression stroke, precise valve control ensures the mixture is fully compressed, raising the temperature and pressure in the combustion chamber to lay the foundation for efficient combustion. During the combustion phase, the well-conditioned mixture burns faster and more completely, releasing more energy to drive the piston—greatly improving the engine’s thermal efficiency.
Custom-designed for the VW/Audi A4 2.0T engine, the 06B109088D achieves deep compatibility with the engine in terms of dimensional specifications, installation interfaces, and operating logic. Its design fully adheres to VW/Audi’s OE standards, allowing direct, seamless replacement of the original component without any modifications or adjustments to the engine’s surrounding structure. This not only simplifies the installation process but also ensures stability and efficiency when the eccentric shaft gear works in tandem with other engine components (e.g., timing chain, camshaft, valve train), maximizing the restoration of the vehicle’s original performance.
2. High-Quality Materials and Craftsmanship
The 06B109088D is made of high-strength, wear-resistant premium special steel. This steel undergoes a specialized smelting process to deliver excellent mechanical properties, enabling it to withstand the complex and harsh operating environment inside the engine—such as high temperatures (up to 150℃–200℃), high pressure (extreme combustion chamber pressure), and high-frequency mechanical impact. During manufacturing, advanced precision machining processes and high-accuracy CNC equipment are used to refine critical parts like tooth profile and pitch, controlling tooth surface roughness to a minimum. This ensures precise, smooth gear meshing, efficient power transmission, and ultra-low noise. Additionally, key parts undergo specialized heat treatment to further enhance surface hardness and internal toughness, effectively extending the product’s service life to over 150,000 kilometers under normal use.
