HONEYCERAM: Substrates for automobile catalytic converters
NGK Insulator's fine ceramic technology is appreciated worldwide by automobile manufacturers.
Offered in square or hexagonal cell configurations (the latter especially effective in conserving the volume of catalyst used), HONEYCERAM is used by auto manufacturers worldwide. The total production of HONEYCERAM has reached about 1.5 billion units.
Large-size HONEYCERAM (LSH)Designed for use with large diesel vehicles, this HONEYCERAM model carries a catalyst that removes particulate matter (PM) as well as nitrogen oxide (NOx) from diesel exhaust gas
DPFs, Gasoline particulate filters, NOx sensors
Diesel particulate filters/gasoline particulate filters
Lightweight cordierite filters (both sides of the photograph) are mainly used in trucks, buses, construction machinery, and other large vehicles. The more heat-resistant silicon carbide filters (center of the photograph) are used in passenger cars. NGK Insulators also offers a dedicated filter for gasoline direct-injection engine.
These were the world’s first sensors to detect concentrations of NOx in a vehicle in real time. Our NOx sensors consist of ZrO 2 elements and are based on oxygen pumping technology.
