See also Fig. 1 and Fig. 2, it is respectively plan view and the side view of prior-art devices configuration.As shown in the figure, air inlet system includes a suction port 81 and a gas-entered passageway 82, and gas-entered passageway 82 is fixedly arranged on the main car frame 80, and gas-entered passageway 82 also is communicated with air-strainer 85, and the below of air-strainer 85 is then organized and is provided with a transmission device 90.In addition, engine 95 has the camshaft (not shown), and the shaft centre line of camshaft forms a cam shaft center line Y1.
That is, the suction port 81 of locomotive engine 95 air inlet systems of prior art is positioned at the rear of cam shaft center line Y1 at present, the opening of suction port 81 and towards the rear, and near engine 95, when locomotive in travelling, engine 95 is under high rotating speed heavy load, and the air that air inlet system sucks is affected by the thermal radiation of engine 95 easily.In other words, the air that engine 95 ignition suck is hot air, causes engine 95 performance losss, and also easily causes engine 95 pinkings, seriously makes the piston meltdown fault of engine 95, reduces working life, is not very good.
Designer of the present utility model for these reasons, the spirit in line with innovation has designed a kind of " improved arrangement of air inlet system " that can address the above problem, several times research experiment is eventually to finishing the utility model.
The model utility content
Main purpose of the present utility model is to provide a kind of improved arrangement of air inlet system, can avoid air-strainer to suck hot air, that is, reduce engine and produce pinking because sucking hot air, and then can promote engine efficiency, and increase the working life of engine pistons.
For achieving the above object, the improved arrangement of air inlet system of the present utility model is mounted on one to be had on the locomotive of an engine, a main car frame and a transmission device, air inlet system includes a suction port and a gas-entered passageway that is communicated with air-strainer, transmission device connects an air inlet duct, the opening of air inlet duct is towards the place ahead, be installed with a front screen on the main car frame of the opening of contiguous air inlet duct, wherein, the suction port of air inlet system is positioned at the formed space of main car frame, front screen and air inlet duct.
The suction port of above-mentioned air inlet system can be positioned at the top of the opening of air inlet duct.Relatively, the gas-entered passageway of air inlet system also can be positioned at the top of air inlet duct.In addition, the suction port of air inlet system also can be the same with the opening of air inlet duct, towards the place ahead.
The gas-entered passageway of above-mentioned air inlet system can be fixedly arranged on the main car frame or be fixedly arranged on other part.
The suction port of above-mentioned air inlet system can lock at the fuel tank of locomotive between the cam shaft center line of centerline hole and engine, thereby can avoid air-strainer to suck hot air.

Embodiment
See also Fig. 3 and Fig. 4, it is respectively plan view and the side view of the utility model one preferred embodiment.The improved arrangement of the air inlet system of the present embodiment is mounted on the locomotive 1, and locomotive 1 has an engine 10, a main car frame 20, a transmission device 30, an air inlet duct 31, an air inlet system 40 and an air-strainer 45.Wherein, main car frame 20 is provided with plural fuel tank and locks the hole with the fuel tank (not shown) of this locomotive 1 that locks, and wherein fuel tank locks left side and the right side that hole 25,26 lays respectively at main car frame 20, and two fuel tanks lock hole 25,26 and form a fuel tank and lock centerline hole X1.In addition, engine 10 has the camshaft (not shown), and its shaft centre line also forms a cam shaft center line X2.
As shown in the figure, air inlet system 40 includes a suction port 41 and a gas-entered passageway 42, and gas-entered passageway 42 also is communicated with air-strainer 45.In addition, this transmission device 30 connects an air inlet duct 31, and the opening 311 of air inlet duct 31 is towards the place ahead.In addition, the suction port 41 of air inlet system 40 is also towards the place ahead, that is, when locomotive 1 when travelling, the opening 311 of air inlet duct 31 and the suction port 41 of air inlet system 40 are all towards the windward side.
In addition, be installed with a front screen 21 in these opening 311 places of contiguous air inlet duct 31 on the main car frame 20, enter gas-entered passageway 42 and air inlet duct 31 to prevent water or foreign matter.
As shown in Figure 3, the suction port 41 of air inlet system 40 is positioned at main car frame 20, front screen 21 and air inlet duct 31 formed spaces.And suction port 41 locks between the cam shaft center line X2 of centerline hole X1 and engine 10 at the fuel tank of locomotive 1.
