Abstract
The fuel addition system comprises: a fuel addition valve, a fuel tank, a first pressure storage chamber storing fuel to be supplied to a fuel injector, a supply pump increasing a pressure of fuel inside the fuel tank and supplying the fuel to the first pressure storage chamber, a pressure reduction valve discharging fuel stored in the first pressure storage chamber, a pressure reduction fuel passage supplying fuel discharged from the first pressure storage chamber to the fuel addition valve, and a control device controlling the fuel addition valve and the pressure reduction valve. The control device detects or estimates a temperature of fuel supplied to the fuel addition valve and, when injecting fuel from the fuel addition valve, controls an amount of fuel discharged from the first pressure storage chamber through the pressure reduction valve so that the temperature of the fuel becomes a reference temperature or more.
