HONEYCERAM: Substrates for
automobile catalytic converters
NGK Insulator's fine ceramic technology is appreciated worldwide by automobile manufacturers.
A ceramic catalyst carrier, HONEYCERAM neutralizes the harmful substances in automobile exhaust.
HONEYCERAM's honeycomb design results in a large surface area--the area that comes into contact with exhaust--with minimal installation requirements.
In fact, the area coated by the gas-purifying catalyst on a palm-size HONEYCERAM would cover an area equivalent to two soccer grounds.
For maximum exhaust gas cleaning efficiency, HONEYCERAM was designed to have minimal weight and wall thickness: The 0.05 mm walls minimize loss of engine power.
The remarkable properties of cordierite ceramics like HONEYCERAM make it possible to withstand high temperatures and sudden changes in the temperature of exhaust gas.
DPFs, Gasoline particulate filters, NOx sensors
Makes easy-on-the-environment diesel vehicles even cleaner; helps meet exhaust gas regulation requirements.
Diesel vehicles are popular, especially in Europe, due to the fuel efficiency of these vehicles and their low carbon dioxide emissions.
As the world hurries to regulate diesel exhaust gas, we at NGK Insulators have been developing a range of state-of-the-art products designed to meet these new standards.
Our diesel particulate filters make effective use of porous ceramic filter technology to trap particulate matter in their tiny holes.
As the only manufacturer that mass-produces two kinds of diesel particulate filters, cordierite and silicon carbide, we apply ceramic technologies to support the continuing evolution of diesel vehicles.
For accurate measurements, our NOx sensors detect nitrogen oxides (NOx) in exhaust gas at parts per million (ppm) concentrations.
