  • Mounting structure of EGR valve for internal combustion engine
    Patent number: 4938176
    Abstract: A mounting structure for mouting an EGR valve on an intake maniford of an internal combustion engine is disclosed. The intake manifold includes a flange in which boltholes having internal threads are formed. The EGR valve is mounted on the flange by means of bolts. The flange includes a coolant passage inside. Coolant flows into this coolant passage from a cooling system of the engine to cool the boltholes effectively so as to prevent the bolts from loosening due to thermal fatigue of the internal thread portions caused by the high temperatures of recirculated exhaust gas.
