Abstract:
1. An exhaust gas purifying apparatus for an internal combustion engine, which is mounted in a hybrid vehicle including the internal combustion engine and an additional power source as power sources, wherein the internal combustion engine starts and stops automatically based on predetermined conditions, the apparatus comprising: adsorption means which is provided in an exhaust passage of the internal combustion engine and adsorbs predetermined components contained in exhaust gas; a purification catalyst which is provided at a downstream side of the adsorption means in the exhaust passage and purifies the predetermined components; gas supply means for supplying gas to the adsorption means from an upstream side of the adsorption means during a stop of the internal combustion engine; and heating means for heating at least the purification catalyst among the adsorption means, the gas supplied to the adsorption means, and the purification catalyst, wherein the heating means starts heating the purification catalyst, if a high load demand from a driver is issued while the hybrid vehicle is running using the additional power source in a state where the internal combustion engine is stopped; and wherein the heating means heats the purification catalyst when the gas is supplied by the gas supply means.
