The honeycomb heater includes a first portion that is resistance adjusted such that the first portion is adapted to heat more quickly than a second portion of the honeycomb heater. The first portion includes at least an inlet end of the honeycomb that receives gas that flows therethrough. In addition, the first portion has an area along the gas inlet within a range of 5 to 50% of the sectional area of the gas inlet. The first portion may extend through the honeycomb structure and terminate before reaching the gas outlet of the heater. The partition walls of the first portion may have a different hydraulic diameter, different thickness or different cell density than the second portion of the honeycomb heater.

摘要： A catalyst for exhaust gas purification has at least one monolith carrier, at least one first catalyst layer having a three-way catalytic activity, provided on the carrier, and a second catalyst layer having a hydrocarbon purification activity, provided on the first catalyst layer. In a gasoline engine automobile provided with the above catalyst for exhaust gas purification in the exhaust gas system, the hydrocarbons present in the exhaust gas can be converted at a high efficiency by introducing secondary air into the exhaust gas in front of the catalyst to make the exhaust gas lean, at the engine start when a large amount of unburnt hydrocarbons are present in the exhaust gas. Further, the engine warm-up property of the automobile can be improved by the heat generated by the catalytic reaction of the hydrocarbons. The catalyst further exhibits a three-way catalytic activity even during the steady state engine operation after warm-up.
