V-OLvo 4-Pin Injector Model 21569191 Product Description

The V-OLvo 4-Pin Injector Model 21569191 is a high-performance electronic unit 4-pin fuel injector specially developed for V-OLvo heavy-duty diesel engines, mainly compatible with V-OLvo D11A, D11B, D11C and MD11 Euro 5 high-power engines as well as related heavy-duty equipment equipped with the same fuel injection system. As a core component of the engine’s fuel supply system, this injector integrates advanced material technology and precision manufacturing processes, featuring excellent durability, stable injection performance and strong compatibility, fully complying with V-OLvo’s strict OEM quality standards and Euro 5 emission requirements. It adopts high-speed steel for key components and high-quality alloy for the main body, combined with integrated 4-pin electrical connection design and composite surface treatment technology, which ensures fast signal response, accurate fuel injection control, strong corrosion resistance and wear resistance. This injector effectively improves fuel combustion efficiency, reduces exhaust emissions and equipment maintenance costs, and provides a reliable direct aftermarket replacement solution for V-OLvo equipment maintenance with fully interchangeable OEM cross-reference numbers[1][2][4].

This table outlines the basic product information of the V-OLvo 4-Pin Injector Model 21569191, 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, 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][3][4].

This table focuses on the material selection and manufacturing process parameters of the V-OLvo 4-Pin Injector Model 21569191, which are the core factors determining its durability, stable performance and compatibility with V-OLvo D11 series and MD11 Euro 5 engines. The injector adopts high-speed steel (such as SUJ2) for key components like needle valves, high-quality alloy for the main body, and high-temperature resistant seal materials, which can adapt to the harsh working environment of heavy-duty equipment and ensure long-term stable operation[2]. Following V-OLvo’s global uniform manufacturing standards and strict quality control requirements, the product undergoes precision CNC machining, ion nitriding and nano-ceramic coating treatment, as well as 100% factory multi-channel testing, ensuring each injector meets the strict performance requirements of original equipment and is fully compatible with the target engines[2][4].
