Estimating the term…
A diesel engine system includes a diesel engine, a throttle valve, an EGR (Exhaust Gas Recirculation) path, an EGR valve and a controller. The throttle valve controls a flow rate of intake air to the diesel engine. Exhaust gas is recirculated along the EGR path from an exhaust port to an intake port of the diesel engine. The EGR valve controls a flow rate of the exhaust gas. The controller controls the throttle valve and the EGR valve such that an opening of the throttle valve decreases and an opening of the EGR valve increases when a load of the diesel engine increases. The controller controls the EGR valve such that the opening of the EGR valve increases after the opening of the EGR valve is held constant for a first predetermined holding time.
A diesel engine system comprising:
A diesel engine system comprising:
A control method of a diesel engine system including a diesel engine, a throttle valve configured to control a flow rate of intake air to the diesel engine, an EGR (Exhaust Gas Recirculation) path along which exhaust gas is recirculated from an exhaust port to an intake port of the diesel engine and an EGR valve configured to control a flow rate of the exhaust gas, the control method comprising:
