Description of the Invention: [Technical Field] The present invention relates to a large-sized air cleaner that uses an air filter, a cleaner cover, and an air cleaner casing to form an intake passage thereof. [Previous technology #?] The locomotive engine needs to inhale a large amount of air to burn gasoline to generate power during operation. However, in order to prevent the sand dust in the air from damaging the engine cylinder, the air will first use the air filter before entering the cylinder. Filter it. Please refer to Figure 1, which is a schematic diagram of a locomotive. The main frame 11 of the locomotive 10 is extended rearward and downward by the head pipe 15, and a plurality of components such as an air cleaner 17, an engine 19, and the like are hung on the main frame 11, wherein the air cleaner 17 is located at the engine 19. Above, used to filter the air entering the engine cylinders. Please refer to the 2nd and 2nd drawings at the same time. The 2nd drawing is the upper view of the air filter placed on the main frame, and the 2nd drawing is a cross-sectional view taken along the Α-Α * section line of the 2nd drawing. The air cleaner Π has a pair of protruding left and right intake pipes 14 which are arranged on both sides of the main frame 11, and the outside air can enter the air filter 17 from the left and right intake pipes 14 at the same time. The net 16 is filtered and then introduced into the engine 19. The main line of the locomotive (including the power line, the throttle line, the brake line, etc.) 12 is extended along the main frame 11 between the two intake pipes 14. As shown in Fig. 2, there is an unused space C (indicated by a broken line) between the air cleaner 17 and the main frame 11. In the current trend of air filtration of 0314-Α21426TWF(N2); 94-TOP-28; itshen 5 1302179, the present invention uses this space c to increase the size of the air filter, in addition to the air filter The structure of the cleaner and the configuration of the main line are also modified. SUMMARY OF THE INVENTION One object of the present invention is to fully utilize the internal space of a locomotive to increase the size of an air cleaner, and to eliminate the intake duct protruding outward from the conventional air filter, and to change into a built-in intake passage. . • Another object of the present invention is to form the intake passage by means of an air cleaner cover and an air cleaner housing. Still another object of the present invention is to modify the structure of the air cleaner to a single air inlet and to reconfigure the position of the main line of the locomotive. To achieve the above object, an air cleaner of the present invention includes an air cleaner cover, an air cleaner housing, and a screen set. The air cleaner housing is combined with the air cleaner cover to form an air intake passage. The filter set is sandwiched between the air cleaner cover and the air cleaner housing. The Air Filter ® has a single air intake and the main and air intakes of the locomotive are located on either side of the main frame. The above described objects, features, and advantages of the present invention will be more apparent from the description of the preferred embodiments. [Embodiment] Referring to Figs. 3A and 3B, Figs. 3A and 3B are perspective exploded views of the air cleaner of the present invention viewed from opposite directions. The air cleaner of the present invention includes an air cleaner cover 371, a screen set 73, and an air cleaner housing 375. The air filter of the present invention includes an air cleaner cover 371, a filter pack 73, and an air cleaner cover 375. Among them, the screen group 373 is interposed between the air cleaner cover 371 and the air cleaner case 375. The screens, , 73 include a frame 378, and a screen (shown in Figure 4) 379, which is mounted in the frame 378. An air inlet 377 is provided on the air cleaner housing 375 for introducing outside air into the air cleaner. Referring to FIG. 4 at the same time, the air cleaner cover 371 and the air filter peripheral 375 are combined to form an intake passage extending from the air inlet 377 to the filter screen 379 of the filter group. The arrows in the 3rd, 3rd, and 4th arrows show the direction in which air flows along the intake passage. It should be emphasized that in the present embodiment, the air cleaner has only a single air inlet 377. Referring to FIG. 5, when the air cleaner is installed on the main frame 5, the air inlet 377 and the main line of the locomotive (including the power line, the throttle line, the brake line, etc.) 52 are listed in the main frame 51. side. Comparing the second and fifth figures, the present invention increases the size of the air cleaner. [The prior art originally unused space C is occupied by the volume that the present invention has been modified by the air filter, and conventionally known. The intake duct 14 which is originally outwardly protruded from the technology is changed into a built-in intake passage in the present invention, and the intake passage is formed by the air cleaner cover 371 and the air cleaner casing 375, so that The volume of the air filter is maximizing. Furthermore, in order to avoid problems such as increased noise due to too short an intake passage, the present invention designs the intake passage to be curved to ensure that it still has a certain length in a limited space. Although the present invention has been disclosed above in the preferred embodiments, it is not intended to limit the 0314-A21426TWF(N2); 94-TOP-28; itshei 1302179, the present invention, without departing from the spirit of the present invention. In the scope of the invention, the scope of the invention is defined by the scope of the appended claims.
