Abstract
To provide a control device for an internal combustion engine that can optimally control a plasma ignition operation independent of fuel type. In a control device 30 of an internal combustion engine 20, which controls plasma ignition operation for causing volume ignition of air fuel mixture by plasma in a combustion chamber 10, a fuel type detection part 40 detects a type of fuel to be supplied to the combustion chamber 10. According to the detected fuel type, a state of plasma or a state of air fuel mixture in the combustion chamber 10 is controlled.
Claims7
A control device for an internal combustion engine, for controlling a plasma ignition operation to cause volume ignition of air fuel mixture by plasma in a combustion chamber of the internal combustion engine, comprising a fuel type detection unit that detects a type of fuel to be supplied to the combustion chamber, and
- wherein the control device adjusts a state of the plasma or a state of the air fuel mixture in the combustion chamber according to the detected fuel type that has been detected by the fuel type detection unit during the plasma ignition operation.
A control device for an internal combustion engine, for controlling a plasma ignition operation for causing volume ignition of air fuel mixture by plasma in a combustion chamber of the internal combustion engine, comprising:
- a plasma control unit that changes input energy for generating the plasma based on an operation state of the internal combustion engine, thereby adjusting an air fuel ratio of flammability limit of the air fuel mixture to a value that maximizes fuel consumption rate in the operation state, during the plasma ignition operation;
- and
- an air fuel ratio control unit that controls an air fuel ratio of the air fuel mixture in the combustion chamber during the plasma ignition operation to the air fuel ratio of flammability limit, which is determined by the input energy for generating the plasma, of the air fuel mixture.
