ABSTRACT:
An apparatus is disclosed for purifying the exhaust gas of a diesel engine by reducing the contents of soluble organic fractions which are particulates. The apparatus comprises a catalyzer provided on an exhaust pipe, a cooler provided around either a portion of the pipe between the catalyzer and the engine or the catalyzer in itself for cooling the gas flowing through the pipe, a temperature sensor for detecting the temperature of the gas flowing through the pipe, a tachometer for detecting the rotating speed of the engine, a load sensor for detecting the load on the engine, a controller for controlling the cooler on the basis of the respective detection outputs from the sensors.
