V-OLvo 4-Pin Injector Model 21424681 Product Description

The V-OLvo 4-Pin Injector Model 21424681 is a high-precision, reliable common rail fuel injection component specifically engineered for V-OLvo series diesel engines, especially适配 V-OLvo E3.4 diesel engines and other mid-power engine models, as well as V-OLvo light-duty trucks, passenger vehicles and industrial equipment equipped with advanced fuel injection systems. As a core part of the engine’s fuel supply system, this 4-pin injector is distinguished by its excellent precision atomization, stable electrical performance, and strong environmental adaptability, fully complying with V-OLvo’s strict original equipment quality standards, ISO 9001 and ISO/TS 16949 certific-ations. It is manufactured with high-speed steel and corrosion-resistant composite materials, adopting V-OLvo’s professional precision machining and surface treatment processes, including ion nitriding and nano-ceramic coating technologies to enhance wear resistance and corrosion resistance. The integrated 4-pin waterproof and anti-interference electrical connection design ensures fast signal response and stable transmission, even in complex working environments with high humidity and impurities. This injector achieves uniform fuel atomization and accurate injection timing, effectively improving fuel combustion efficiency, reducing fuel consumption by 3%-5% and harmful exhaust emissions, meeting Euro6 emission standards, and solving common faults such as unstable idling and insufficient power. With fully interchangeable OEM cross-reference numbers, it provides a cost-effective and reliable replacement solution for V-OLvo equipment maintenance, ensuring the engine operates stably and efficiently for a long service life.

This table outlines the basic product information of the V-OLvo 4-Pin Injector Model 21424681, 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 and its authorized suppliers, ensuring that users can accurately find compatible replacement parts, avoid mismatches and potential performance risks, and guarantee that the product’s performance is fully consistent with the original equipment, meeting the strict operational requirements of V-OLvo engines.

This table focuses on the material selection and manufacturing process parameters of the V-OLvo 4-Pin Injector Model 21424681, which are the core factors determining its durability, corrosion resistance, and stable performance in long-term operation. The injector’s needle valve is made of high-speed steel with excellent heat stability, which is processed by 1200℃ quenching and -80℃ deep cooling treatment to ensure it can withstand high injection pressure. The injector body adopts corrosion-resistant composite materials with Al₂O₃-TiO₂ composite ceramic coating, effectively resisting fuel corrosion and impurity wear. Following V-OLvo’s global uniform manufacturing standards and ISO/TS 16949 certific-ation requirements, the product undergoes precision CNC machining, ion nitriding treatment, and 100% factory multi-channel testing, ensuring each injector meets the strict performance requirements of original equipment and can adapt to complex working environments.
