Title:
EXHAUST GAS PURIFIER
Document Type and Number:
WIPO Patent Application WO/2017/013989
Kind Code:
A1
Abstract:
In the present invention, exhaust gas heating by a heating device is preferentially selected when activation of a catalytic device is necessary. When the heating device has sufficient capability to heat exhaust gas, the heating device is used to heat the exhaust gas. When the capability of the heating device to heat the exhaust gas is insufficient, combustion timing control for an internal combustion engine is employed to heat the exhaust gas. This reduces unnecessary power consumption, and improves purification efficiency of the catalytic device.
