Engine exhaust emission control device |
| abstract |
An engine exhaust emission control device includes: an electric pump for inlet and pressure feed of a liquid reduction agent in a reduction agent tank; a flow rate control valve for controlling the flow rate of the liquid reduction agent fed under pressure; and an injection nozzle for injecting the liquid reduction agent having a controlled flow rate to the upstream of exhaust of NOx reduction catalyst. Upon engine start, air under a high pressure is fed back to a reduction agent supply system located at the upstream of the flow rate control valve and so as to judge whether the reduction agent supply system is clogged according to the pressure change. When the number of judgments that the reduction agent supply system is clogged exceeds a predetermined number, it is judged that a fatal clogging which cannot be easily removed has occurred in the reduction agent supply system. |
