摘要： An engine controlling apparatus includes a setting unit that sets a demand torque to an engine, a detection unit that detects a fluctuation of an external load, and a correction unit that corrects the demand torque. The apparatus includes a target torque calculation unit that calculates a target torque based on the demand torque, a control unit that controls an amount of air to be introduced into the engine so that an output torque may come close to the target torque, and an ignition timing detection unit that detects an ignition timing of the engine.The correction unit adds a torque increment for coping with a fluctuation of the external load to the demand torque to determine an increment correction demand torque and increases or decreases the increment correction demand torque in response to a displacement amount of the ignition timing from a predetermined reference value.

摘要： Disclosed is a variable valve gear comprising a camshaft phase change mechanism, which variably controls a phase of an intake cam with respect to a crankshaft, and a variable valve lift mechanism, which changes an opening timing of an intake valve more than a closing timing and basically continuously varies a lift and an open period of the intake valve. The lift and the open period are set lest the intake valve interfere with a piston of an engine, with the phase controlled to be most advanced by the camshaft phase change mechanism and the lift controlled to be maximal by the variable valve lift mechanism.

摘要： In a variable valve gear for an internal combustion engine provided with a camshaft phase change mechanism for variably controlling opening and closing timings of an intake valve, the camshaft phase change mechanism and a variable valve lift mechanism are controlled so that the closing timing of the intake valve is advanced beyond a predetermined range T1 including a bottom dead center when a load L of the internal combustion engine is less than a first predetermined value L1 and that the closing timing of the intake valve is delayed beyond the predetermined range T1 when the load L of the internal combustion engine is not less than the first predetermined value L1.
