c-aterpillar Injector M11 Series (Part Number: 3411845) Product Details

The c-aterpillar 3411845 fuel injector is a high-precision OEM-grade component specifically engineered for the c-aterpillar M11 series diesel engines, and it is fully compatible with Cummins M11, ISM11, QSM11 engines, serving as the critical core of the engine’s fuel injection system. As a genuine and reliable matching part, it is also widely applied to Cummins QSM11 engines and适配 XCMG XE470 excavators. Its exceptional precision, robust performance, and strict compliance with c-aterpillar’s original standards are key to ensuring efficient fuel atomization, stable power output, optimized fuel economy, and long-term operational durability of the M11 engine. Produced in facilities certified by ISO 9001:2015, ISO/IATF16949:2016 and CE, this injector adheres strictly to c-aterpillar’s design specific-ations and material requirements for the M11 series, undergoing rigorous quality control throughout the entire production process—from raw material procurement (adopting original imported materials) to final assembly and functional testing, with 100% performance testing before delivery. We implement a systematic quality control and validation system, including first article inspection (FAI) and in-process quality control (IPQC) to ensure product stability. As a key matching part for M11 series plunger systems, it is constructed with high-strength alloy steel and high-temperature resistant sealing components, integrating advanced precision machining and heat treatment technologies, which enables it to withstand the harsh working environments of M11 engines, including high temperature, high pressure, and long-term continuous operation. This scientific design not only effectively reduces fuel consumption and exhaust emissions but also enhances wear resistance and corrosion resistance, significantly extending the service life of both the injector and the engine. As a direct bolt-on OEM replacement part (also available as 3411845DR variant), it requires no installation modific-ations, comes with matching sealing components for secure fitment, and is backed by a 12-month limited warranty, along with comprehensive global after-sales support, making it a reliable and cost-effective maintenance solution for c-aterpillar M11 engine users in construction, heavy-duty transportation, industrial power, mining, and marine sectors. It is widely recognized as a high-performance matching part for M11, ISM11, QSM11 engine fuel injection systems, compatible with various M11-based equipment and perfectly matching the M11 plunger system specific-ations, with sufficient in-stock supply for timely delivery.
