    • To provide an exhaust emission control device of an internal combustion engine able to well atomize a reducing agent and ensure supply of combustion air. Since a controller of the exhaust emission control device also controls a nozzle opening degree of a variable geometry turbocharger for purpose of spraying a urea water, even in the state where the engine works in a low load range of T1 to T2 where supercharging pressure normally can not be increased, supercharging pressure P suitable to atomization of the urea water can be obtained by controlling the nozzle opening degree of the variable geometry turbocharger to be closer to a closing side compared to the conventional art (shown by the chain double-dashed line), while the urea water can be securely atomized by a part of the supercharged air. Further, by increasing the supercharging pressure up to the value P, combustion air supplied to the engine is increased, therefore favorable combustion can be realized, and generation of particulates and exhaust of unburned fuel can be reduced.
    • 提供能够充分雾化还原剂并确保供给燃烧空气的内燃机的废气排放控制装置。 由于废气排放控制装置的控制器也控制用于喷射尿素水的可变几何涡轮增压器的喷嘴开度,即使在发动机在T 1至T 2的低负载范围内工作的状态下,其中增压压力 通常不能增加,与现有技术相比,通过控制可变几何涡轮增压器的喷嘴开度更接近关闭侧,可以获得适合于尿素水雾化的增压压力P. 线),而尿素水可以被一部分增压空气牢固地雾化。 此外,通过将增压压力提高到P值,供给到发动机的燃烧空气增加,因此能够实现良好的燃烧,能够降低未燃燃料的微粒和废气的产生。

    • A blade of a hybrid type fan includes: a blade body 21 made of a synthetic resin; and a metallic insert 22 that is insert molded simultaneously with the blade body 21 and mounted to a mounting arm of a spider. At a corner on an outer side of a radial direction and a forward side of a rotary direction of the insert 22, a bulging portion 26 is provided to bulge toward the outer side of the radial direction and the forward side of the rotary direction. A bulging region 27 of the bulging portion 26 that the most prominently bulges toward the outer side of the radial direction is located to be forward in the rotary direction relative to a mounting center C of the insert 22 and the mounting arm along the radial direction.
