Tungsten Disulfide (WS₂) Fullerene Nanoparticles in Oil Suspension

• Advanced lubricant additive designed to improve engine efficiency, reliability, and service life.

• Challenge: Military and heavy-duty vehicle engines operate in extreme environments where conventional oils and greases are insufficient to prevent wear, cold-start difficulties, and premature breakdown. Vehicle downtime due to engine degradation leads to higher operational costs, reduced reliability, and mission delays.

Problem:

Users faced multiple performance and maintenance challenges:

• High friction and abrasion in moving engine parts reduced lifespan and increased maintenance frequency.

• Cold-start difficulties in harsh environments increased operational risks and fuel consumption.

• Excessive noise and vibration during operation compromised efficiency and long-term reliability.

• Conventional lubricants provided limited protection, leading to accelerated wear and costly replacements.

Solution

Canyon Engineering introduced tungsten disulfide (WS₂) fullerene nanoparticles in oil suspension as an advanced additive to existing oils and greases. Leveraging their exceptionally low-friction, anti-abrasive, and self-healing properties, WS₂ nanoparticles formed a protective nanoscale layer between metal surfaces, reducing wear and enhancing lubrication under all operating conditions.

Results & Benefits

• Extended Lubricant Life: WS₂ nanoparticles increased lubricant lifespan by up to 50%, reducing the frequency of oil changes.

• Extended Engine Life: Engines treated with WS₂ showed significantly longer operational lifespans due to reduced wear and friction.

• Improved Power & Reliability: Vehicles experienced noticeable power gains and improved reliability across extended operating cycles.

• Safer Cold Starts: WS₂-enabled lubrication facilitated easier and safer cold starts, minimizing risk in harsh climates.

• Lower Noise Levels: Engines operated with reduced frictional noise, improving efficiency and crew comfort.

• Fuel Savings: Reduced internal friction translated into lower fuel consumption, contributing to cost savings and sustainability.

✨ Summary

By integrating tungsten disulfide (WS₂) nanoparticle additives into conventional oils and greases, Canyon Engineering delivered a next-generation solution that significantly enhanced the performance and reliability of military and heavy-duty vehicle engines.

With measurable benefits—up to 50% longer lubricant life, extended engine durability, improved cold starts, lower noise, and fuel savings—this innovation demonstrates the transformative power of nanotechnology in the defense and automotive industries..
