Electric exhaust gas recirculation valve |
摘要 |
An electrically actuated EGR valve controls the recirculation of exhaust gases in an internal combustion engine. The EGR valve includes a step motor having a linearly moving motor shaft engaging a rod of a poppet valve for communicating an exhaust gas inlet port with an exhaust gas outlet port. An insulator and a cooling atmosphere chamber separate the step motor from the heat of the exhaust gases.
