Abstract: PROBLEM TO BE SOLVED: To provide a warm-up control device for an internal combustion engine capable of suppressing an increase of fuel consumption and emission when a temperature difference occurs between cylinder groups.
SOLUTION: In the warm-up control device, the internal combustion engine 1 is equipped with a water temperature sensor 64 capable of detecting the temperature of a first cylinder group 11 arranged on a first bank 16 and the temperature of a second cylinder group 12 arranged on a second bank 17 based on the water temperature of the first bank 16 and the water temperature of the second bank 17. Further, an ECU 70 of the internal combustion engine 1 is provided with a start control portion 75 for performing such start control as to start only the cylinder group 10 higher in temperature when the temperatures of the cylinder groups 10 detected by the water temperature sensor 64 are different from each other. Thus, when the temperature of the first cylinder group 11 is different from that of the second cylinder group 12 at the time of starting the internal combustion engine 1, only the cylinder group 10 higher in temperature is started first. As a result, it is possible to suppress an increase of fuel consumption and emission when the temperature difference occurs between the cylinder groups 10.

Abstract: PROBLEM TO BE SOLVED: To provide a controller for optimally controlling an internal combustion engine based on a property of fuel actually supplied to the internal combustion engine. SOLUTION: The controller includes a fuel property sensor 23 disposed in a fuel supply tube 20 between a fuel tank 21 and a fuel injection valve 18. The controller calculates an accumulated value of a fuel injection quantity from the start of fuel supply, and controls the engine based on a fuel property before supplied, until the accumulated value of the fuel injection quantity reaches a predetermined threshold. On the other hand, the controller controls the engine based on a fuel property newly detected by the fuel property sensor 23, after the accumulated value of the fuel injection quantity reaches the predetermined threshold. The threshold is approximately equivalent to a quantity of a fuel before supplied remaining in a fuel passage, when the fuel supply is completed. COPYRIGHT: (C)2008,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of preventing degradation of the emission characteristic when oil dilution occurs.
SOLUTION: When oil dilution with a fuel is detected, the intake valve opening timing is set to be before ATDC 30° to prohibit the delayed opening of an intake valve. The advanced closing of the intake valve is prohibited by increasing the operating angle of the intake valve to set the intake valve closing timing to be after BBDC 30°. By prohibiting the delayed opening and the advanced closing of the intake valve, generation of the in-cylinder negative pressure when detecting the oil dilution is suppressed.
