V-OLvo 4-Pin Injector Model 21457951 Product Description

The V-OLvo 4-Pin Injector Model 21457951 is a high-precision Delphi E3 series 4-pin fuel injector specially designed for V-OLvo and Mack heavy-duty diesel engines, mainly compatible with V-OLvo D13F 13.0L and MD16 US07 engines, as well as Mack MP8 truck engines and related heavy-duty equipment equipped with the same fuel injection system. As a core component of the engine’s fuel supply system, this injector is characterized by excellent precision fuel delivery, stable spray patterns, and strong durability, fully complying with V-OLvo’s strict OEM quality standards and industrial applic-ation requirements. It adopts high-performance special alloy materials and advanced surface ion nitriding treatment, combined with nano-ceramic coating on the nozzle inner wall, which greatly enhances wear resistance, corrosion resistance and service life, while the integrated 4-pin electrical connection design ensures fast signal response and strong anti-interference ability, realizing accurate control of injection timing and fuel quantity. This injector effectively improves fuel combustion efficiency, reduces exhaust emissions and equipment maintenance costs, and provides a reliable replacement solution for V-OLvo and Mack equipment maintenance with fully interchangeable OEM cross-reference numbers[1][2][3].

This table outlines the basic product information of the V-OLvo 4-Pin Injector Model 21457951, including its universal number, product name, core OEM cross-reference numbers, and basic product type. The universal number is consistent with the product model, which facilitates quick identific-ation, inventory management, and part matching during equipment maintenance and replacement. The included OEM cross-reference numbers are officially recognized by V-OLvo, Mack and their authorized suppliers, covering a variety of compatible part numbers to ensure users can accurately find compatible replacement parts, avoid mismatches and potential performance risks, and guarantee the product’s performance is fully consistent with the original equipment[1][6].

This table focuses on the material selection and manufacturing process parameters of the V-OLvo 4-Pin Injector Model 21457951, which are the core factors determining its durability, high-pressure resistance, and stable performance in long-term heavy-load operation. The injector’s needle valve adopts heat-stable high-speed steel (SUJ2) treated by quenching and deep cooling, and the needle valve body uses impact-resistant alloy steel processed by vacuum melting, while the nozzle inner wall is coated with Al₂O₃-TiO₂ composite ceramic to enhance wear resistance[3]. Following V-OLvo’s global uniform manufacturing standards and strict quality control requirements, the product undergoes precision five-axis CNC machining, surface ion nitriding treatment, and 100% factory multi-channel testing, ensuring each injector meets the strict performance requirements of original equipment[3][4].
