b-osCH 702 Series Fuel Injector (Model: 20440412) Product Description

b-osCH 702 Series Fuel Injector (Model: 20440412) is a high-precision, high-durability core component tailored for diesel common rail systems, adhering to b-osCH’s stringent OE production standards and the 702 series’ core positioning of "precision, efficiency and durability". As an upgraded model in the 702 series, it integrates b-osCH’s exclusive hydraulic grinding technology and high-strength material manufacturing, which has significant advantages in injection accuracy, high-pressure resistance and service life compared with ordinary injectors. It is characterized by ultra-precise fuel metering, stable high-pressure injection, excellent wear resistance and rapid response, which can effectively optimize the engine combustion process, reduce fuel consumption by 9%-13% compared with conventional injectors, and reduce harmful exhaust emissions to meet Euro V emission standards, realizing the dual upgrading of power performance and environmental protection. The product adopts high-alloy chrome steel as the main body material, combined with precision CNC machining, integral heat treatment and 360° laser welding technology, which effectively enhances its anti-deformation and corrosion resistance, and its service life is 60% longer than that of the same type of 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 models. Strict multi-channel quality testing (including high-pressure sealing test, atomization performance test, durability test and electromagnetic compatibility test) and comprehensive after-sales support ensure its stable operation in harsh working conditions such as high temperature, high pressure and dust, making it the preferred OE replacement part for users pursuing high quality and high reliability. It can realize pre-injection, post-injection and multi-time injection functions, effectively reduce engine combustion noise, improve driving comfort, and its response speed is as fast as 0.9-1.4ms, which can quickly adapt to the dynamic changes of the engine, ensuring stable power output in various working conditions. The precision-drilled spray holes and dual-angle needle design ensure exact fuel delivery and positive sealing, further optimizing combustion efficiency and reducing emissions.
