Title:
ＶＧターボ搭載車のＥＧＲガス量制御方法及びその装置
Document Type and Number:
Japanese Patent JP6582533
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an EGR gas amount control method for a vehicle mounted with a VGT turbo, which enables proper EGR control even in a transit period, and a device therefor.SOLUTION: In an EGR gas amount control method for a vehicle mounted with a VGT turbo, a VGT turbo 22 is connected to the suction/exhaust system of an engine 10, and on the basis of a fuel injection amount and an engine rotational frequency, an EGR valve 33 is controlled so as to become a target EGR gas amount. The EGR gas amount control method sets a transit period EGR opening map 45 in which opening of an EGR valve for controlling an EGR gas amount in an operational transit period is set; determines a transit state from change of the engine rotational frequency, the fuel injection amount and accelerator opening; and in the transit period, controls EGR opening from the transit period EGR opening map 45.SELECTED DRAWING: Figure 1
