b-osCH 702 Series Fuel Injector (Model: 3835257) Product Description

b-osCH 702 Series Fuel Injector (Model: 3835257) is a high-performance core component specially designed for medium and heavy-duty diesel common rail systems, adhering to b-osCH’s rigorous OE production standards and the 702 series’ core concept of "precision, durability and energy saving". As a key model in the 702 series, it integrates upgraded piezoelectric injection technology and ergonomic structural optimization, which is superior to the previous generation in terms of response speed and fuel utilization rate. It is characterized by ultra-precise fuel metering, excellent high-pressure stability, strong anti-interference performance and wide temperature adaptability, which can effectively improve the combustion efficiency of diesel engines, reduce fuel consumption by 8%-12% compared with ordinary injectors, and reduce harmful exhaust emissions to meet Euro V emission standards[5]. The product adopts high-quality corrosion-resistant alloy steel as the main material, combined with precision CNC machining, integral heat treatment and 360° laser welding technology, which greatly enhances its wear resistance and service life, and its service life is 50% 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 medium and heavy-duty commercial vehicles, industrial diesel equipment, engineering machinery and small marine diesel engines equipped with b-osCH common rail engines, especially suitable for IVECO, CASE, FIAT and other models. Strict multi-channel quality testing (including high-pressure sealing test, atomization performance test and durability test) and comprehensive after-sales support ensure its stable operation in harsh working conditions, making it the preferred OE replacement part for users pursuing high quality and high efficiency. It can realize pre-injection and post-injection functions, effectively reduce engine noise and improve driving comfort, and its response speed is as fast as 1-1.5ms, which can quickly adapt to the dynamic changes of the engine[6].
