Certificate of Honor
Conventional Fuel · Cylinder Liners
● High Wear-Resistant Cast Iron Material
Custom formula of high-phosphorus/boron-containing alloy cast iron, designed for engines over 840 HP, ensuring stable performance under high-temperature and high-pressure conditions to support high thermal efficiency powertrains.
● Efficient Lubrication Honing Process
Special cross-hatch honing technology ensures high oil film retention and low friction, matching the requirements of high-efficiency gearboxes for smooth shifting and lossless power transmission.
● Impact-Resistant Wet Structure
Wet liner design with direct coolant contact for high heat dissipation efficiency, ensuring stable long-term operation, reducing maintenance costs, and achieving over 98.5% transmission efficiency.
Alternative Fuel · Cylinder Liners
● Accumulated Material Technology
As one of the first suppliers of cylinder liners for natural gas heavy-duty trucks, we launched dedicated liners for CNG engines as early as 2005. For 590 HP LNG engines, we have upgraded corrosion-resistant alloy coatings to lead industry technology upgrades.
● High-Efficiency and Reliable Adaptability
Optimized liner structure for gas engine characteristics, compatible with gas engines with 54.16% thermal efficiency. Relevant models have passed extreme condition tests, resisting combustion by-product corrosion and ensuring stable long-term operation.
New Energy · Cylinder Liners (Hybrid/Hydrogen ICE)
● Dedicated Design for Hybrid Systems
Custom-designed cylinder liners for hybrid systems, with lightweight construction and low-friction inner surfaces, efficiently adapting to hybrid powertrains and ensuring power output efficiency in hybrid systems.
● High-Standard Anti-Corrosion Coating
Ceramic-based composite coating for new energy engines such as hydrogen, resisting high-temperature hydrogen corrosion and wear to meet the high reliability requirements of new energy powertrains.
● Intelligent Working Condition Adaptation
Optimized liner friction characteristics for hybrid system control logic, maintaining stable performance under complex conditions like start-stop and variable loads, extending component life when paired with energy recovery systems.
Reliability Verification
Through five key stages—material R&D, process design, simulation analysis, bench testing, and real-engine validation—we conduct comprehensive reliability verification on cylinder liners to ensure the delivery of stable, durable, and high-quality products to our customers.
Component Validation
Mechanical property testing, wear and corrosion resistance testing, thermal fatigue endurance testing
Assembly Validation
Interference fit simulation analysis, hot/cold assembly fit testing, sealing performance verification
Working Condition Validation
Extreme high-temperature and high-pressure condition testing, alternating load fatigue testing, multi-fuel compatibility verification
