Title:
ＥＧＲ装置およびＥＧＲ弁の特性検査装置
Document Type and Number:
Japanese Patent JP5761138
Kind Code:
B2
Abstract:
The exhaust gas re-circulation (EGR) apparatus has an EGR valve (42) for opening or closing a passage of an EGR pipe (41), and a differential pressure sensor (43) is provided to detect an EGR differential pressure. The differential pressure in the EGR pipe is between the pressure of the exhaust gas in upstream and downstream of the EGR valve. An EGR gas temperature, particularly a temperature of the exhaust gas in the EGR pipe, is detected by a temperature sensor (44). A target EGR flow rate is calculated by a calculating section. An independent claim is included for a characteristic detector for an exhaust gas re-circulation valve of the exhaust gas re-circulation device.
