EXHAUST EMISSION PURIFYING APPARATUS FOR ENGINE |
摘要 |
An exhaust emission purifying apparatus for an engine in which it is determined that a reducing agent supply system is clogged, which is arranged on the downstream of a pump carrying out suction and pumping of a liquid reducing agent out of a reducing agent tank, when a reduction in a pressure of the liquid reducing agent remaining in the downstream of the pump and also in the upstream of a flow control valve by an amount equal to or more than a first predetermined pressure does not occur until a cumulative injection amount obtained by sequentially integrating an injection amount of the liquid reducing agent computed in real time based on engine operating conditions reaches a predetermined amount after the pump has been temporarily stopped. |
