摘要：
A controller is provided for an engine comprising urea-SCR catalyst, a urea-water supply section, a low pressure gas recirculating section including a low pressure EGR pipe forming a low pressure EGR passage and a low pressure EGR valve. The controller controls an amount of a fuel supplied to the engine, and an opening degree of the low pressure EGR valve. The controller supplies the urea-water to the urea-SCR catalyst in such a manner that an ammonia flowing out from the urea-SCR catalyst neutralizes an acid condensed water produced by a gas passing through the low pressure EGR passage.
