摘要： An internal EGR control device for an internal combustion engine can, even if the actual valve timing of an exhaust valve changes due to aging and other causes, appropriately control the amount of internal EGR while compensating influence by the change, thereby appropriately controlling the temperature in a cylinder. The internal EGR control device (1) sets a target internal EGR amount (EGRINCMD), which is a target of the amount of internal EGR, according to detected operating conditions (NE, PMCMD) of the engine (3) and calculates internal energy (QACT) which a combusted gas has and is determined according to the amount and temperature of the combusted gas. Further, the internal EGR control device (1) corrects the target internal EGR amount (EGRINCMD) according to the calculated internal energy, calculates the timing of closure of the exhaust valve (9) according to the corrected target internal EGR amount (EGRINC), and controls a variable valve mechanism (60) based on the calculated timing of closure of the exhaust valve (9).

摘要： There is provided an internal EGR control device for an internal combustion engine, which, even when a change in the actual valve timing of exhaust valves is caused by aging, is capable of properly controlling an internal EGR amount while compensating for an adverse influence caused by the change, and thereby properly controlling the temperature within the cylinder. The internal EGR control device 1 sets a target internal EGR amount EGRINCMD which serves a target of the internal EGR amount, according to detected operating conditions, NE and PMCMD, of the engine 3, and calculates internal energy QACT possessed by burned gases, which is determined according to the amount and temperature of the burned gases. Further, the target internal EGR amount EGRINCMD is corrected according to the calculated internal energy, and the valve-closing timing of the exhaust valve 9 is calculated according to the corrected internal EGR amount EGRIN. Further, the variable valve mechanism 60 is controlled based on the calculated valve-closing timing of the exhaust valve 9.
