20150337744 | CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE - An object of this invention is to appropriately control valve timings based on a fuel property and an engine temperature to improve exhaust emissions. An engine is equipped with a function that drives variable valve mechanisms to execute intake valve retarded-opening control and exhaust valve early-closing control. An ECU variably sets a low-temperature determination value based on an alcohol concentration in a fuel. If a water temperature of the engine is equal to or less than the low-temperature determination value, the ECU prohibits the intake valve retarded-opening control and permits the exhaust valve early-closing control. Consequently, during cold operation it is possible to avoid a deterioration in combustion properties (deterioration in in-cylinder turbulence) caused by intake valve control and thereby suppress a deterioration in exhaust emissions. Further, because exhaust valve control is permitted, for example, a negative overlap period that satisfies a control request can be secured by advancing the closing timing of the exhaust valve. Accordingly, exhaust emissions and catalyst warm-up performance can be improved. | 2015-11-26 |
