Technical field
The utility model relates to mechanical engineering, illumination, heating, weapon, explosion, and the supply of general combustion engine ignition mixture or its constituent element, be specially adapted for the air inlet device on internal-combustion engine, espespecially a kind of engine air inlet tube.
Background technique
Burning in cylinder needs to introduce air by suction tude, and suction tude is generally all made up of the some arms be responsible for being connected supervisor and cylinder, arm number needs wherein will determine according to number of cylinders, but existing main suction tude is all the suction tude of the different-diameter of suction tude that diameter is identical or segmentation welding usually, the identical pipe of diameter can not by air evenly be assigned to by all means, the existence due to weld seam of segmentation welding causes suction tude to there is gas leakage.
Summary of the invention
Provide a kind of engine air inlet tube for the problems referred to above the utility model, this device structure reasonable standard, easy to use, the design of and helix shaping by integrally casting, effectively can increase the air inflow of suction tude.
For solving the problems of the technologies described above, the utility model provides a kind of engine air inlet tube, comprises body, inlet end, curved part, outlet side, it is characterized in that: body left end is provided with inlet end, is provided with bump on the right side of inlet end, is provided with curved part in the middle part of body, keep right in the middle part of body and be provided with enlarging section, connection outlet side, enlarging section, outlet side internal surface is smooth surface, and outlet side internal surface is provided with two helixes, the degree of depth of helix is 0.5 millimeter, is provided with bump on the left of outlet side.
As further improvement of the utility model, described outer surface of tube body is provided with organic coating, and organic coating is hydrophobic fluorine resin.
As further improvement of the utility model, described body is integrated casting.
As further improvement of the utility model, described outlet side diameter is 76 millimeters.
Working principle:
The utility model passes through the shaping engine air inlet tube of integrally casting, effectively can solve deficiency of air and the segmentation welding gas leakage of same diameter, be provided with the pressure that curved part effectively can strengthen air inlet in the middle part of body simultaneously, the design of enlarging section effectively can discharge the pressure that curved part accumulates, strengthen the flow of air inlet, the smooth setting of outlet side internal surface simultaneously, effectively can strengthen the effect of helix, the design of outlet side helix can make air output form rotation, strengthen the air feed of main suction tude to branched pipe, make branched pipe air feed evenly abundant to ensure engine combustion, the setting of outer surface of tube body organic coating simultaneously, there is good self-cleaning effect, effectively can prevent the absorption of dust.
The utility model compared with prior art has following beneficial effect:
