Abstract
An exhaust purification system includes: a fuel injection amount acquisition unit, which acquires a fuel injection amount of a vehicle; a temperature acquisition unit which acquires a temperature of a catalyst for reducing and purifying nitrogen compounds in exhaust; a temperature control unit, which controls the temperature of the catalyst; and an execution control unit, which causes the temperature control unit to increase the temperature of the catalyst when the temperature of the catalyst is lower than a predetermined threshold and the fuel injection amount satisfies a predetermined condition.
Claims6
An exhaust purification system comprising:
- a fuel injection amount acquisition unit, which acquires a fuel injection amount of a vehicle;
- a temperature acquisition unit, which acquires a temperature of a catalyst for reducing and purifying nitrogen compounds in exhaust;
- a temperature control unit, which controls the temperature of the catalyst;
- and
- an execution control unit, which causes the temperature control unit to increase the temperature of the catalyst when the temperature of the catalyst is lower than a predetermined threshold and the fuel injection amount satisfies a predetermined condition.
A control method comprising:
- acquiring a fuel injection amount of a vehicle;
- acquiring the temperature of a catalyst which reduces and purifies nitrogen compounds in exhaust;
- and
- increasing the temperature of the catalyst when the temperature of the catalyst is lower than a predetermined threshold and the fuel injection amount satisfies a predetermined condition.
