摘要： PROBLEM TO BE SOLVED: To increase a scavenging amount of internal EGR gas as much as possible, in a valve system for an internal combustion engine scavenging internal EGR gas during a valve overlap period.SOLUTION: In a valve system for an internal combustion engine scavenging internal EGR gas during a valve overlap period by changing a working angle of an exhaust valve, a lift change rate when the exhaust valve is opened is increased, thereby increasing an exhaust pulsation cycle. In the case, since a period when an exhaust pressure exceeds an intake pressure during the valve overlap period is reduced or eliminated, an scavenging amount of internal EGR gas is increased.

摘要： PROBLEM TO BE SOLVED: To provide a valve gear for an engine, appropriately raising compression end temperature in a compression chamber.SOLUTION: This valve gear 1A for the engine includes a variable valve train 57A individually changing the opening timing and closing timing of an exhaust valve 55 at a constant lift, the exhaust valve being provided with respect to the combustion chamber E for the compression self-ignition engine 50A. The closing timing of the exhaust valve 55 is individually delayed according to the compression end temperature in the combustion chamber E. In this regard, since the valve gear 1A for the engine includes an ECU 70A, the closing timing of the exhaust valve 55 is individually delayed by controlling the variable valve train 57A by the ECU 70A. Specifically, in the valve gear 1A for the engine, the closing timing of the exhaust valve 55 is individually delayed when the engine 50A is in a warming-up process.

摘要： PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine which suppresses over-temperature rise of a catalyst in the deceleration of the internal combustion engine.SOLUTION: A variable valve system A operates a valve opening characteristic by an ECU (Electronic Control Unit) targeting valve elements (an intake valve, an exhaust valve) having the changeable valve opening characteristic. When there is a high risk of over-temperature rise (OT) of the catalyst, valve timing is controlled to suppress the degree of reduction (deceleration rate) of engine speed. Work of compression is made small by reducing pump loss in a large working angle and high lift and delaying the timing of the closing of the intake valve compared with the normal operation like valve opening characteristic 24. In the deceleration of the internal combustion engine, the engine speed is decreased at a relatively mild inclination compared with the normal case (Base). As a result, the quantity of the catalyst supply gas is reduced at a relative mild inclination compared with the normal (Base) case.

摘要： PROBLEM TO BE SOLVED: To accurately calculate an intake air quantity, even when valve close timing of an exhaust valve is advanced or when a blow-back quantity of exhaust gas is increased.
SOLUTION: When an advance quantity α of the valve close timing of the exhaust valve 36 is an advance reference value θ1 or less, an ECU 50 calculates the intake air quantity based on output of a supercharging pressure sensor 48 high in calculation accuracy of the intake air quantity and high in responsiveness. When the advance quantity α gets larger than the advance reference value θ1 by a valve timing control, the ECU determines that an error has occurred in output of the supercharging pressure sensor 48 by the blowing back of the exhaust gas to calculate the intake air quantity based on output of an airflow sensor 24. Therefore, a calculation method of the intake air quantity is appropriately used based on the advance quantity α of the exhaust valve 36 (the blow-back quantity of exhaust gas), so that a variety of sorts of controls using the intake air quantity can be executed with high accuracy.
