    摘要： An internal combustion engine is provided with a variable valve mechanism (30, 31) capable of altering opening and closing timings and / or opening amounts of at least one of an intake valve (28) and an exhaust valve (29) of an internal combustion engine. A fuel injection valve (32) supplies fuel either directly or indirectly to a combustion chamber (24) of the internal combustion engine. A forcible valve closing means (20) controls the variable valve mechanism (30, 31) such that at least one of the intake valve (28) and the exhaust valve (29) is placed in a closed state when the fuel injection valve (32) is prohibited from operating. New gas is prevented from flowing from the exhaust system of the internal combustion engine to the intake system thereof when fuel injection control is prohibited.

    摘要： An internal combustion engine is provided with a variable valve train (30, 31) capable of altering opening and closing timings and/or opening amounts of at least one of an intake valve (28) and an exhaust valve (29) of an internal combustion engine. The internal combustion engine is further provided with a negative pressure mechanism (100) that operates using intake pipe negative pressure generated in an intake passage (33, 34, 35) of the internal combustion engine, a throttle valve (39) for adjusting the flow rate of intake air flowing through the intake passage (33, 34, 35), and negative pressure generating means (20) for controlling at least one of the variable valve train (30, 31) and the throttle valve (39) to generate the intake pipe negative pressure, when the intake pipe negative pressure for operation of the negative pressure mechanism (100) is insufficient.

    摘要： An internal combustion engine having a variable valve train (30, 31) capable of adjusting opening/closing timing and/or an opening amount of at least one of an intake valve (28) and an exhaust valve (29) of the internal combustion engine and a throttle valve (39) for adjusting an amount of intake air flowing through an intake passage (33, 34, 35) of the internal combustion engine, comprises engine control means (20) for controlling the variable valve train (30, 31) such that pump efficiency of the internal combustion engine is increased and for closing the throttle valve (39) by a predetermined amount when a predetermined condition is satisfied. The engine control means (20) controls the variable valve train (30, 31) and closes the throttle valve (39) such that occurrence of torque fluctuation in the internal combustion engine is prevented when said predetermined condition is satisfied.
