b-osCH 702 Series Fuel Injector (Model: 0414702019) Product Description

b-osCH 702 Series Fuel Injector (Model: 0414702019) is a high-precision core component for diesel common rail systems, adhering to b-osCH’s global OE production standards and the 702 series’ core positioning of high reliability, high efficiency and environmental protection. As a key model in the 702 series, it integrates b-osCH’s exclusive hydraulic grinding technology (a special abrasive medium is used to round the edges of the spray hole inlets)[1], advanced electromagnetic control system and optimized sealing structure, which has remarkable advantages in fuel atomization precision, high-pressure stability, service life and emission reduction compared with conventional injectors. Its core features include ultra-precise fuel metering (error ≤±0.01%), fast response speed (0.26-0.60ms), strong high-pressure bearing capacity (peak 3200bar) and excellent sealing performance, which can effectively improve engine combustion efficiency, reduce fuel consumption by 14%-18%, and reduce harmful emissions to fully meet Euro VI emission standards, realizing a perfect balance between power output, energy saving and environmental protection. The product adopts high-strength chrome alloy steel as the main body material[1], with core components undergoing carburizing and quenching treatment, combined with precision CNC machining (micron-level matching accuracy) and 360° laser welding technology, which significantly enhances its wear resistance, corrosion resistance and anti-deformation ability, and its service life is 95% longer than that of similar products. It is fully compatible with matching OEM cross-reference numbers, supports plug-and-play installation without complex modific-ation, and is widely applicable to heavy-duty commercial vehicles, industrial diesel equipment, engineering machinery and small marine diesel engines equipped with b-osCH common rail engines, especially suitable for Cummins, IVECO, CASE, c-aterpillar and other mainstream models. Strict multi-channel quality testing (100% pre-delivery inspection) and comprehensive after-sales support ensure its stable operation in harsh working conditions such as high temperature, high pressure and dust, making it an ideal OE replacement part for users pursuing high reliability and cost-effectiveness. Each product is fully calibrated before leaving the factory, with complete calibration protocols, ensuring consistent performance and strong interchangeability, and is perfectly compatible with related pump nozzle maintenance kits. It is closely matched with other models in the 702 series, facilitating later maintenance and replacement, and can be queried through professional b-osCH parts query channels to ensure the authenticity and compatibility of the parts.
