Abstract

PURPOSE: To supply air without preheating during high-load and speed-reduction periods and also to supply preheated secondary air during the idle, low-load, and medium-load periods.
CONSTITUTION: The upstream side of the exhaust cleaner 5 is led to the switching valve device 15 through the first lines 9 and 11 and the preheater 7 and also directly through the second line 13. During high-load period or speed-reduction period, the solenoid 45 becomes ON and the valve 47 is risen and thereby the negative pressure of intake pipe is supplied from the large chamber 39 of the electromagnetic valve 37 to the diaphragm chamber 29 and the valve 25 is risent to supply secondary air from the air pump 33 to the exhaust system 3 through the second line 13. On the other hand, during the idle, low-load, and medium-load periods, in which the solenoid 45 in OFF, preheated air from the preheater 7 is supplied to the exhaust system 3 through the first line. Thus, the overheating of the exhaust cleaner can be prevented.
