A combustion chamber liner is a cylindrical component that protects the chamber walls from extreme heat and pressure in internal combustion engines.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Wall Thickness | 3-8 mm | |
| Pressure Rating | Up to 250 bar | |
| Surface Roughness | Ra 0.8-1.6 μm | |
| Diameter Tolerance | ±0.05 mm | |
| Thermal Shock Resistance | ΔT > 500°C/min | |
| Operating Temperature Range | -40°C to 1200°C |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is used in the following industrial products
The enclosed space within a combustion system where fuel and oxidizer mix and burn to produce high-temperature gases.
The high-pressure section of a mud pump where fluid is pressurized and discharged.
A high-temperature component in gas turbines where fuel is mixed with compressed air and ignited to produce hot gases that drive the turbine.

Service life varies by application: 8,000-15,000 hours for industrial gas turbines, 500,000-1,000,000 km for automotive diesel engines, or 2-5 years for stationary engines depending on operating conditions and maintenance schedules.
Common detection methods include: 1) Visual inspection for cracks or erosion, 2) Dimensional measurement for wall thickness reduction, 3) Pressure testing for leaks, 4) Thermal imaging for hot spots, and 5) Vibration analysis for abnormal patterns.
Minor surface damage can often be repaired through welding and machining, but significant cracking, erosion exceeding 20% of wall thickness, or thermal distortion typically requires complete replacement to maintain safety and performance.
