Product Description:
b-osCH D12 Series Fuel Injector (Model: 1440578) Product Description
The b-osCH D12 Series Fuel Injector, Model 1440578, is a high-quality OE-grade common rail fuel injector specially designed for medium and heavy-duty diesel engines, integrating b-osCH’s mature fuel injection technology and strict quality management system to provide reliable performance, precise fuel delivery, and strong adaptability to various harsh operating conditions. As a key model in the D12 Series, this injector is manufactured with 100% genuine b-osCH components, featuring a compact and durable structure, a precision-machined high-speed steel nozzle with anti-wear and anti-corrosion treatment, and a high-sensitivity electromagnetic control module that ensures rapid response to ECU signals for optimal fuel atomization. Originating from Germany, it is built to withstand extreme temperature ranges (-40℃ to 220℃), high working pressure, and long-term continuous operation, making it ideal for commercial trucks, industrial diesel generators, construction machinery, and other heavy-duty equipment equipped with compatible D12-series diesel engines. Adhering to b-osCH Global OE Standards, IATF 16949, ISO 9001:2015, and b-osCH’s core quality requirements, it undergoes rigorous multi-stage testing—including high-pressure sealing tests, atomization performance checks, and long-term durability tests—to ensure stable operation and extended service life. This injector boasts core advantages of low fuel leakage, strong wear resistance, high interchangeability, and excellent combustion optimization. It effectively improves fuel atomization efficiency, reduces fuel consumption and harmful emissions (meeting Euro V and EPA Tier 4 standards), while enhancing engine power output and operating stability. Its direct OE replacement design ensures seamless compatibility with b-osCH D12 series fuel systems, facilitating convenient installation and maintenance. With strict quality control throughout the production process, the 1440578 injector embodies b-osCH’s professional expertise in diesel fuel injection technology, making it a reliable choice for commercial and industrial applic-ations that demand high performance and consistency.
