c-aterpillar Injector M11 Series (Part Number: 4307516) Product Details

The c-aterpillar 4307516 fuel injector is a high-precision, OEM-standard common rail injector specifically engineered for the c-aterpillar M11 series diesel engines, and it is fully compatible with Cummins QSNT-C345 engines (a key variant of the M11 series) and other related M11-based engine models. As a critical core component of the engine’s fuel injection system, it is widely applied to construction machinery and heavy-duty equipment equipped with these engines, with a standard usage of 6 injectors per unit equipment[2]. Its outstanding fuel atomization performance, stable delivery accuracy, and strict compliance with ISO 9001:2015 and c-aterpillar OEM quality standards are essential to ensuring efficient fuel combustion, stable engine power output, optimized fuel economy, and long-term operational durability of the M11 and QSNT-C345 engines. Produced in certified manufacturing facilities that adhere to national quality infrastructure (NQI) standards[3], this injector strictly follows the design specific-ations and material requirements of the c-aterpillar M11 series, adopts high-quality alloy steel as the main material, and undergoes rigorous quality control throughout the entire production process—from raw material procurement (with strict chemical composition analysis and physical performance testing[4]) to final assembly and functional testing, with 100% professional performance testing before delivery to ensure consistent and reliable performance. We implement a comprehensive quality control and validation system, including first article inspection (FAI), in-process quality control (IPQC), and finished product testing with precision instruments, to guarantee product stability and consistency. As a key matching part for M11 and QSNT-C345 fuel injection systems, it integrates advanced precision machining technologies, enabling it to withstand harsh working environments such as 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 (verified by salt spray and high-temperature wear tests[4]), significantly extending the service life of both the injector and the engine. As a direct bolt-on OEM replacement part, it requires no installation modific-ations, is available with neutral or original packaging, and is backed by a 6-month limited warranty, along with efficient after-sales support and timely delivery (1-day delivery for local orders, 3-7 days for bulk and international orders[2]), making it a cost-effective and reliable maintenance solution for c-aterpillar M11 engine users in construction, heavy-duty machinery, and industrial sectors. It is widely recognized as a high-quality matching part for M11 and QSNT-C345 engine fuel injection systems, compatible with various M11-based construction machinery, with a minimum order quantity that can meet both individual maintenance and bulk procurement needs[2].
