摘要： An exhaust gas purification device includes a NOx adsorption catalyst (36) and HC supply means (48) for adding HC to the exhaust gas flowing to the NOx adsorption catalyst (36). The HC supply means (48) is controlled first to supply an amount of HC required to keep the temperature of the NOx adsorption catalyst (36) at a second temperature which is derived by subtracting a temperature rise caused by rich spike from a first temperature predetermined as a temperature necessary for S purge, thereby increasing the temperature of the NOx adsorption catalyst (36), and then to additionally perform the rich spike for the S purge while continuing the HC supply.
