ENGINE CONTROL SYSTEM AND METHOD |
摘要 |
An engine system includes a fuel supply unit configured to supply fuel into a combustion chamber. The engine system includes a fuel supply unit to regulate the supply of fuel into an inlet port via a fuel rail and an air supply unit configured to supply compressed air into the combustion chamber. A control system is configured to receive operating conditions of the engine system. Further, the control system includes a detector component configured to generate a control signal indicative of a start-up condition of an engine system. A switching component of the controller receives the control signal indicative of the start-up condition of the engine system from the detector component and further transmits a fuel supply control signal to the fuel valve based on an air-fuel ratio error signal, and transmit an air supply control signal to the choke valve based on an engine speed error signal. |

1. An engine system comprising:
a fuel supply unit configured to supply fuel into a combustion chamber, the fuel supply unit including a fuel valve configured to regulate the supply of fuel into an inlet port via a fuel rail; an air supply unit configured to supply compressed air into the combustion chamber, the air supply unit including a choke valve configured to regulate the supply of air into the inlet port via an air inlet manifold; and a control system configured to receive operating conditions of the engine system, the control system comprising:
a detector component configured to generate a control signal indicative of a start-up condition of an engine system; anda switching component receives the control signal indicative of the start-up condition of the engine system from the detector component, the switching component configured to transmit a fuel supply control signal to the fuel valve based on an air-fuel ratio error signal, and transmit an air supply control signal to the choke valve based on an engine speed error signal. |
