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.

CPC classification number: Y02T10/40
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.

Abstract: PROBLEM TO BE SOLVED: To consistently execute initial firing after completing preheat control. SOLUTION: The preheat control is executed during the motoring of an internal combustion engine 10. In the preheat control, the return of high-temperature compressed air is jetted into an intake port 20 by opening and closing an intake valve 38 while an exhaust valve 40 is closed. In an intake stroke for initial explosion executed immediately before initial firing, the valve-opening timing of the intake valve 38 is advanced from the valve-opening timing during the preheat. Thus, in the intake stroke for the initial explosion, fuel injection can be executed after the return of the compressed air remaining in a combustion chamber 16 is weakened by preheat control. Thus, the jetted fuel can be consistently injected into the combustion chamber 16, and a misfire or the like can be prevented. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To achieve synchronous gear change in a wide range as much as possible without increasing a makeup of a motor in a hybrid vehicle. SOLUTION: A hybrid mechanism 20 can provide a plurality of gear change steps including a 1-speed CVT (Continuously Variable Transmission) mode which uses MG (Motor Generator) 1 as a reaction force factor and uses MG2 as an output factor, and a 2-speed CVT mode which uses MG2 as the reaction force factor and uses MG1 as output factor. In switching of the gear change step between the modes of 1- speed CVT and 2-speed CVT, synchronous gear change without accompanied by change of engine speed of an engine 200 is carried out. In this case, an ECU (Electronic Control Unit) 100 computes a short time rated value based on thermal load of the MG1 and MG2, and permits a synchronous gear change in an operating range beyond the regular rated value in the range of this short time rated value.
