| 摘要 | An engine system includes an engine, an air intake passage to supply air to the engine, a throttle valve provided in the air intake passage to adjust a throttle opening degree that is an opening degree of the air intake passage, a bypass passage to supply air to the engine while bypassing the throttle valve, an on/off valve provided in the bypass passage to open and close the bypass passage, and a control unit that performs ignition lag control of the engine to control an output of the engine when the on/off valve is in an open state. | ||

| 主权项 | 1. An engine system comprising: an engine; an air intake passage that supplies air to the engine; a throttle valve, provided in the air intake passage, that adjusts a throttle opening degree which is an opening degree of the air intake passage; a bypass passage that supplies air to the engine and bypasses the throttle valve; an on/off valve, provided in the bypass passage, that opens and closes the bypass passage; and a control unit programmed to perform an ignition lag control of the engine to control an output of the engine when the on/off valve is in an open state; wherein the control unit is programmed to judge whether or not the engine is in a starting period, and when the control unit judges that the engine is in the starting period, the control unit is programmed to control the on/off valve to be in the open state and thereafter to execute the ignition lag control of the engine. | ||
