Title:
統合排気ガス再循環バルブ付きターボチャージャ制御用のインテリジェント・エレクトリック・アクチュエータ
Document Type and Number:
Japanese Patent JP4625226
Kind Code:
B2
Abstract:
An exhaust gas recirculation (EGR) system for an engine with a variable geometry turbocharger (18) incorporates a master rotary electric actuator (REA) (50) with a microprocessor controller (53) receiving condition signals (46, 48a-e) from sensors (48) associated with the turbocharger and the engine control unit (ECU) (54) and positioning the turbine inlet nozzle (44) geometry of the turbocharger in response to a predetermined matrix of the condition signals. A slave REA (52) is connected through an internal processing unit (58) to the controller to position an EGR valve (34). The processing unit provides an actual position signal to the controller which responds with a desired position signal based on the predetermined condition signal matrix. The processing unit engages the slave REA to position the EGR valve.
