INTERNAL COMBUSTION ENGINE AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE

摘要

An internal combustion engine includes a variable valve mechanism (44) that takes a valve characteristic of an intake valve, and changes the valve characteristic according to an engine operating state; a turbocharger (30) that includes a bypass passage (34) that bypasses a turbine wheel (31) arranged in an exhaust passage by connecting a portion of the exhaust passage that is upstream of the turbine wheel to a portion of the exhaust passage that is downstream of the turbine wheel and a waste gate valve (35) that adjusts a flow path area of the bypass passage; and a control apparatus configured to, when there is a request to increase the valve characteristic according to a change in the engine operating state change the valve characteristic to an increase side with the variable valve mechanism after opening the waste gate valve to an opening amount that is larger than before the request.
