Keeping the air clean using exhaust purification technologies

NGK helps protect the environment through air purification technologies compatible with enhanced exhaust regulations. We supply a full range of ceramics for both diesels and gasoline-powered vehicles. HONEYCERAM, a ceramic structure, carries a catalyst that neutralizes the harmful substances found in vehicle exhaust. Employing a honeycomb structure that makes it possible to create large surface areas within confined spaces, a HONEYCERAM unit small enough to be held in the hand incorporates a surface area equal to that of two soccer pitches. Thanks to our pursuit of thin walls and light weight to maximize exhaust purification efficiency, HONEYCERAM walls are a mere 0.05 mm thick. This also minimizes loss of engine power. Made using cordierite ceramics, HONEYCERAM demonstrates outstanding performance unimpaired by high temperatures and sudden temperature changes accompanying vehicle exhaust.
