Control device for internal combustion engine

The invention relates to a control device for an internal combustion engine. When the amount of PM collected by the GPF reaches a predetermined amount, the CPU executes a regeneration process for regenerating the GPF. Namely, the CPU stops the supply of fuel to any one of the cylinders # 1 to # 4, and increases the amount of fuel supplied to the remaining cylinders. When the temperature of the three-way catalyst is equal to or higher than the first temperature, the CPU increases the injection amount in order to decrease the temperature of the exhaust gas. The CPU does not increase the injection amount when the temperature of the three-way catalyst is equal to or greater than the first temperature during the execution of the regeneration process. 本发明涉及一种内燃机的控制装置。CPU在GPF捕集的PM量达到规定量的情况下，执行将GPF再生的再生处理。即，CPU停止向气缸#1～#4中的任1个的燃料的供给，另一方面，将向剩余的气缸供给的燃料量增量。CPU在三元催化剂的温度成为第一温度以上的情况下，为了使排气的温度下降而将喷射量增量。CPU在再生处理的执行中三元催化剂的温度成为第一温度以上的情况下，不将喷射量增量。
