INTERCOOLER CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To keep a quantity of condensate water generated when intake air is cooled to an appropriate quantity when EGR gas is cooled using the condensate water.SOLUTION: A second cooling part 50 implements heat exchange between condensate water 2 produced in a first cooling part 48 and EGR gas and the second cooling part 50 includes a reservoir part 58. When a quantity of the condensate water 2 in the reservoir part 58 is smaller than a lower limit value, an intercooler control device 25 raises cooling efficiency of the first cooling part 48 so as to increase the quantity of the condensate water 2 to be produced in the first cooling part 48.SELECTED DRAWING: Figure 12
