Integrated EGR valve housing

摘要

An integrated exhaust gas recirculation (EGR) valve housing includes: a temperature control passage configured to include a first cooling channel which connects a water jacket formed in an engine to a radiator and a second cooling channel which is branched from the first cooling channel and extends to an EGR cooler cooling re-circulated exhaust gas; and an auxiliary cooling passage configured to guide cooling water introduced into the second cooling channel to the EGR valve housing, whereby it is possible to easily dispose the EGR valve housing in the engine compartment by integrating the parts through which the cooling water is discharged from the engine with the cooling water channel connected to the EGR valve housing.

1. An integrated exhaust gas recirculation (EGR) valve housing, comprising:
an exhaust gas circulation passage mounted in an EGR valve housing through a flange and configured to be opened and closed by an EGR valve; a first temperature control passage including a first cooling channel which is provided at one side of the exhaust gas circulation passage and connects a water jacket formed in a cylinder head to a radiator and a second cooling channel which is branched from the first cooling channel and connects the first cooling channel to an EGR cooler; and an auxiliary cooling passage branched from the second cooling channel and connecting the water jacket to the EGR valve housing.
