Exhaust gas recirculation control for diesel engine |
摘要 |
In an apparatus for controlling the EGR in a diesel engine, a single pressure control valve adjusts the control pressure from a pump automatically when the pressure changes, and supplies the control pressure in response to the command signal of a control circuit to an EGR valve and a waste-gate valve of a turbocharger. The pressure control valve includes an electric actuator, a spool valve, a sleeve, a diaphragm, and a spring. By using this apparatus, a diesel engine which has a high response speed, high control precision, simple constitution, less nitrogen oxides in the exhaust gas, and low manufacturing cost is obtained.
