b-osCH 702 Series Fuel Injector (Model: 20440409) Product Description

b-osCH 702 Series Fuel Injector (Model: 20440409) is a high-performance core component specially designed for diesel common rail systems, adhering to b-osCH’s strict OE production standards and the 702 series’ core positioning of "precision, durability and energy saving". As a key model in the 702 series, it integrates advanced hydraulic control technology and high-precision manufacturing processes, which has obvious advantages in injection stability and environmental adaptability compared with ordinary injectors. It is characterized by precise fuel metering, strong high-pressure resistance, excellent wear resistance and fast response speed, which can effectively optimize the engine combustion process, reduce fuel consumption by 8%-12% compared with conventional injectors, and reduce harmful exhaust emissions to meet Euro V emission standards, realizing the dual improvement of power performance and environmental protection performance[5]. The product adopts high-strength corrosion-resistant alloy steel as the main body material, combined with precision CNC machining, integral heat treatment and 360° laser welding technology, which effectively improves its service life and reliability, and its service life is 55% 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 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 1.0-1.5ms, which can quickly adapt to the dynamic changes of the engine, ensuring stable power output in various working conditions[6].
