b-osCH D12 Series Fuel Injector (Model: 1920420) Product Description

The b-osCH D12 Series Fuel Injector, Model 1920420, is a premium OE-grade fuel injection component specifically designed for b-osCH D12 series heavy-duty diesel engines, leveraging b-osCH’s advanced precision engineering and reliable electronic control technology. Distinguished by its exceptional atomization performance, superior high-pressure tolerance, and outstanding durability, this injector serves as a perfect OE replacement for a variety of commercial and industrial heavy-duty equipment. Made from 100% authentic b-osCH materials imported from Germany, it features a precision-machined nozzle with a wear-resistant and corrosion-resistant ceramic coating, which effectively withstands the abrasion of fuel impurities and harsh working environments, ensuring stable fuel supply and absolute leak-proof sealing. Equipped with a high-sensitivity ball-type electromagnetic valve, it responds to ECU signals in just 0.25ms, accurately controlling injection timing and fuel volume to improve combustion efficiency, reduce fuel consumption by 15-20%, and reduce harmful emissions to meet Euro V, Euro VI, and EPA Tier 4 Final emission standards. With excellent thermal stability (-45℃ to 230℃) and strong environmental adaptability, it can achieve reliable cold starts and stable operation in extreme conditions such as high altitude, low temperature, and dusty construction sites. Adhering to b-osCH Global OE Standards, IATF 16949, and ISO 9001:2015, the injector undergoes rigorous multi-stage quality testing, including 2400Bar high-pressure sealing test, atomization performance test, and 2500+ hours of durability test, ensuring consistent performance and prolonged service life. Its core advantages—high precision, strong reliability, simple maintenance, and wide compatibility—make it the first choice for heavy-duty commercial vehicles, industrial diesel generators, and construction machinery, providing stable and efficient power support for various heavy-load operating scenarios.
