Cummins 3636374 Joint Gasket For QSK60 Engine

Functional gradient metal layer:

The surface layer is made of laser-melted cobalt-based alloy (Co-28Cr-6Mo), with a hardness of HRC 58, which resists micromotional wear of the cylinder liner; the intermediate layer is annealed copper foil (thickness 0.1mm), which compensates for microscopic unevenness on the contact surface through plastic deformation; the bottom layer is a 316L stainless steel support skeleton, with a tensile strength of ≥860MPa.

Intelligent elastomer interlayer:

Embedded with 3M patented fluorosilicone rubber (FLS-264), which maintains the elastic modulus fluctuation rate ＜±8% within the range of -40℃ to 300℃, and encapsulates the corrosion inhibitor (benzotriazole derivatives) through microcapsule technology, which is automatically released when pH＜5 is detected.

1. Intelligent preload management system

Built-in RFID chip records the bolt tightening curve and compares the standard torque-angle curve through special APP (in line with SAE J1943 standard).

Automatic compensation of torque coefficient in special environments such as plateau/low temperature (accuracy ±1.5%)

1. Dynamic sealing technology

Pressure-activated sealing mechanism: when the pressure inside the cylinder is detected to be >180bar, the internal micro-cavity ruptures and releases nano sealant (patented formula) to fill the microscopic leakage channels.

2. Full Life Cycle Carbon Footprint Optimisation

70% recycled metal used as raw material (UL ECOLOGO certified)

39% less energy consumption than traditional gaskets, ISO 14067 carbon footprint certified.

3. Multi-physical field coupling design

Developed multi-physical field simulation platform with ANSYS to simultaneously optimise the sealing performance under the coupling of thermal-force-fluid-chemical fields, shortening the development cycle by 60% compared with the traditional trial-and-error method.
