    摘要: A fuel pump is constructed of a pump casing, a rotating member and a reinforcing member. The pump casing internally forms a pump chamber, in which the rotating member is received, such that the rotating member rotates to pressurize fuel in the pump chamber. The reinforcing member reinforces the pump casing against fluidic force applied to the pump casing. The pump casing is formed of resin. The reinforcing member is insert-formed in the pump casing, so that the reinforcing member is at least partially embedded in the pump casing.

    摘要: An exhaust gas purifying system for an internal combustion engine includes a first exhaust passage (22a) and a second exhaust passage (22b) into which an exhaust passage (21) of the internal combustion engine is bifurcated. NOx storage reduction catalysts (23a, 23b) and particulate filters (24a, 24b) are provided in each of the exhaust passages (22a, 22b). Fuel is supplied from a fuel valve (32) when NOx is to be released from the NOx storage reduction catalysts (23a, 23b). At a timing when the supplied fuel attaches to the NOx storage reduction catalysts (23a, 23b), one of exhaust control valves, for example, a first exhaust control valve (26a) is temporarily closed so as to keep the air-fuel ratio of exhaust gas rich. When NOx is released from the NOx storage reduction catalysts (23a, 23b) next time, a second exhaust control valve (26b) is temporarily closed after the fuel is supplied.

    摘要: The present invention provides a technology enabling regeneration of the purification performance of an exhaust purification device more reliably and more efficiently in an exhaust purification system combining a plurality of branch passages bifurcating from an exhaust passage and an exhaust purification device provided in each branch passage. When regenerating the purification performance of a first exhaust purification device provided in a first branch passage, a second valve provided in a second branch passage is set at a predetermined first intermediate opening and a first valve provided in the first branch passage is fully closed. Fuel is then added from a first fuel addition valve provided in the first branch passage.
