Abstract

PURPOSE: To compatibly control exhaust refluent amount to reduce NOx particularly at the time of high load in such a way that according as the load in the internal combustion engine increases, the exhaust refluent amount increases, and over the settled load, it is reduced to the contrary with use of a valve.
CONSTITUTION: In the structure that intake and exhaust pipes 1, 2 in the internal combustion engine are conducted by an exhaust refluent pipe 2 having a cyclone 3 to eliminate dust and a reflux control valve 4 in order to reduce Nox in the exhaust, the control valve 4 is interlocked through a throttle valve 6A and levers 8, 9, 10, a bellows 11 to receive exhaust pressure in the refluent pipe 2 is connected upon the control valve 4 in the sequence after that with increase of opening degrees of a throttle valve 6A, the opening degrees of the control valve 4 are increased, at the same time, a bellows 11 to receive exhaust pressure in the refluent pipe 2 is connected upon the control valve 4. Therefore, when the exhaust pressure in the exhaust pipe 1 rises beyond a settled value during the drive under the load, the bellows 11 expands, and the opening degrees of the control valve are put on the way of decreasing.
