Beyond Spark Plugs: Ceramics Power Modern Vehicles
From the engine to the exhaust and brakes, advanced ceramics help automakers meet stringent demands for efficiency, emissions, and performance.
Core Automotive Applications:
-
Engine & Drivetrain:
-
Glow Plug Tips: Silicon Nitride tips enable faster cold starts and lower emissions in diesel engines.
-
Turbocharger Rotors: Ceramic (Si₃N₄) rotors are lighter than metal, reducing turbo lag and improving fuel economy.
-
Valve Train Components: Wear-resistant ceramic parts for reduced friction and longer life.
-
-
Exhaust & Emissions Control:
-
Oxygen (O₂) & NOx Sensors: Zirconia-based electrolytes are the heart of these critical emission control sensors.
-
Catalyst Substrates & Particulate Filter Walls: Porous cordierite ceramics provide the vast surface area needed to trap soot and host catalytic materials.
-
-
Braking Systems:
-
Carbon-Ceramic Brake Discs: Offer fade-free braking, exceptional durability, and significant weight reduction for high-performance and luxury vehicles.
-
-
Electrification & New Mobility:
-
Battery & Fuel Cell Components: Ceramics used in thermal management, insulation, and sensing within EV batteries and hydrogen fuel cells.
-
Sensor Housings & Insulators: Throughout the vehicle's electrical and electronic systems.
-
Benefits for Automotive Engineers:
-
Weight Reduction: Lower rotational and unsprung mass improves handling and efficiency.
-
High-Temperature Capability: Enables higher engine operating temperatures for better efficiency.
-
Durability: Withstands harsh under-hood and exhaust environments for the vehicle's lifetime.
-
Precision: Enables accurate sensing and control critical for modern engine management.
The Future: As vehicles evolve toward electrification and higher efficiency, the role of ceramics is expanding into battery technology, power electronics, and advanced sensors, making them a key material for the future of transportation.
