Product Description

Cummins M11/Qsm11/ISM11 Engine Thermal Management Nozzle 6515104/4955978/4982634
Cummins M11/Qsm11/ISM11 Engine Thermal Management Nozzle 6515104/4955978/4982634
Product Overview
The Cummins M11, QSM11, and ISM11 Engine Piston Cooling Nozzles with part numbers 6515104, 4955978, and 4982634 are indispensable components engineered to safeguard engine longevity and optimize performance. These interchangeable nozzles are designed to deliver a precisely controlled stream of cooling oil to the pistons, effectively dissipating heat and preventing thermal - related failures.

Unmatched Cooling Efficiency
These piston cooling nozzles feature an advanced design that ensures maximum heat transfer. The precisely calibrated orifices are optimized to create a fine - mist spray pattern, covering the entire underside of the piston for uniform cooling. This results in a significant reduction in piston temperature, enhancing combustion efficiency and minimizing the risk of piston distortion or cracking. By maintaining optimal piston temperatures, these nozzles contribute to lower emissions and improved fuel economy across the M11, QSM11, and ISM11 engine series.

Oil Atomization
Droplet size ≤ 0.5mm for enhanced heat transfer
Precision Engineering and Interchangeability
Robust Construction for Harsh Environments
Manufactured to the highest standards, these nozzles undergo rigorous quality control processes. The use of advanced CNC machining and metrology ensures that each nozzle, regardless of part number, meets the exact specifications required for seamless operation within the M11, QSM11, and ISM11 engines. Their interchangeability provides flexibility for maintenance and repair, allowing for quick replacement with minimal downtime.
Constructed from premium heat - resistant alloys, these nozzles are built to withstand the extreme conditions inside an engine. They resist corrosion from engine oil additives and contaminants, while their mechanical strength ensures they can endure high - pressure oil flow and engine vibrations. This robust construction translates to a long service life, reducing the total cost of ownership for engine operators.
