Abstract
A fuel injection valve is for injecting fuel to cause combustion in an internal combustion engine. An injection rate adjuster is for adjusting an injection rate of the fuel injected by the fuel injection valve. A control device for the internal combustion engine includes a signal generator, and an outputter. The signal generator generates a command signal to cause the injection rate adjuster to adjust the injection rate based on a parameter, which is to estimate an internal EGR amount in which a part of exhaust gas remains in a cylinder. The outputter outputs the command signal to the injection rate adjuster.
Claims13
A control device for an internal combustion engine, the internal combustion engine including a fuel injection valve, which is for injecting fuel to be burned in an internal combustion engine, and an injection rate adjuster, which is to adjust an injection rate of the fuel injected by the fuel injection valve, the control device comprising:
- a signal generator configured to generate a command signal, which is to cause the injection rate adjuster to adjust the injection rate, based on a parameter, which is for estimating an internal EGR amount of a part of exhaust gas remaining in a cylinder;
- and
- an outputter configured to output the command signal, which is generated by the signal generator, to the injection rate adjuster.
A control device for an internal combustion engine, the control device comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to perform:
- acquiring a parameter, which is for estimating an internal EGR amount of a part of exhaust gas, which remains in a cylinder;
- and
- generating a command signal based on the parameter to cause adjustment of an injection rate of fuel injected by a fuel injection valve.
A method for controlling an internal combustion engine, the method comprising:
- acquiring a parameter, which is for estimating an internal EGR amount of a part of exhaust gas, which remains in a cylinder;
- and
- generating a command signal based on the parameter to cause adjustment of an injection rate of fuel injected by a fuel injection valve.
