Abstract: A fuel injector 100 includes a nozzle member 60 having a fuel passage 60a leading to an injection port 60b; a valve main body 51 adapted to reciprocate for opening and closing the fuel passage 60a; an elastic portion 56 elastically deformable in closing the fuel passage 60a by movement of the valve main body 51 in a closing direction, the elastic member being attached to one of the nozzle member 60 and the valve main body 51 and adapted to be abutted against the other of the nozzle member 60 and the valve main body 51 to close the fuel passage 60a by moving the valve main body 51 in the closing direction; and a stopper 70 adapted to restrict movement of the valve main body 51 in the closing direction by being abutted against the valve main body 51, the stopper 70 being formed of material different from the nozzle member 60.

Abstract: A fuel injector which injects a gaseous fuel includes a nozzle and a housing. The nozzle has an outlet which injects the gaseous fuel at a flow rate greater than or equal to a predetermined rate. The housing has a mixing chamber which communicates with the outlet. The housing further has an air introducing passage which introduces an outer air into the mixing chamber and an injection hole which injects an air-mixed fuel formed by mixing the gaseous fuel with the outer air. Thus, a mixing of the gaseous fuel and the outer air can be improved, and the gaseous fuel can be efficiently combusted.

Abstract: An exhaust emission control apparatus is provided with a supply device, a catalyst, and a gas pressure reduction part. The supply device supplies a reducing agent to an exhaust passage. The catalyst purifies an exhaust gas by the use of the reducing agent. The gas pressure reduction part can make a gas pressure near the supply port lower than the gas pressure on the inside of a supply device body. A NOx catalyst adsorbs nitrogen oxide contained in the exhaust. NOx adsorbed by the NOx catalyst is desorbed from the NOx catalyst when the exhaust gas is purified. An ECU estimates an adsorption amount of NOx. Then, the ECU estimates a desorption amount of NOx desorbed from the NOx catalyst on the basis of the estimated adsorption amount of NOx.
