8-97306-063-4 High-Pressure Common Rail Pipe - Engine Fuel System Common Rail Assembly
The common rail (8-97306-063-4) is a core component of the high-pressure fuel system in diesel engines. It stores and stably distributes high-pressure fuel, maintaining a constant fuel pressure before injection to ensure precise injector operation. Made of high-strength alloy steel, this product features high pressure resistance, corrosion resistance, and strong sealing properties, making it suitable for construction machinery and commercial engines operating under continuous high loads and complex conditions.
The common rail has a precise structure and its interface dimensions are identical to the original equipment manufacturer (OEM), allowing for direct replacement without modification. Stable fuel pressure output significantly improves engine combustion efficiency, reduces fuel consumption, and improves emissions performance, making it a widely used high-quality replacement component for maintenance and replacement.
Features and Advantages
• High Pressure Stability: Capable of withstanding and stably supplying high-pressure fuel, improving injection accuracy;
• Wear and Corrosion Resistance: Made of high-quality alloy steel, corrosion-resistant and fatigue-resistant;
• Improved Combustion Efficiency: Stable fuel supply, improving engine power and fuel economy;
• Easy Replacement: OEM size consistent, can directly replace the original common rail pipe;
