Air filter housing for a motorized towing vehicle or snow blower On many motorized towing vehicles and snow blowers, after a snowfall, the engine starts to run unevenly, arbitrarily decrease and increase its speed (the engine speed becomes noticeably "floating"), loses power, and sometimes even loses the ability to move the equipment. This is especially noticeable if the outside air temperature is not too low. The reason is that fluffy, unpacked snow easily rises into the air, as they say in the North - "kurzhit", that is, it creates a cloud of snow dust. This dust penetrates through the cracks of the factory air filter. The vacuum in the air filter housing "pulls" hot air from the nearby red-hot muffler housing of the exhaust system. This heating of the air sucked into the air filter housing further increases the moisture content in the sucked air. In the carburetor channel, the air cools due to the vacuum, and the moisture condenses on the walls of the channels in the form of frost, causing the carburetor, jets, and valve to freeze. This freezing over-enriches the mixture and disrupts the engine. Tested on the Bars Sledopyt motorized towing vehicle with a Honda engine. Printing on K1, nozzle 0.4, layer 0.2: 1. base of the housing - PETG, 4 walls (for rigidity), filling 20% gyroid; 2. housing - PETG, 3 walls, filling 15% gyroid, with regular overhang supports up to 60 degrees, supports only from the table; 3. gaskets in the hole in the base of the air filter housing - TPU, 2 walls, filling 15% gyroid; 4. gaskets on the upper part of the air filter - TPU, 2 walls, filling 10% gyroid; 5. Insert in the base of the housing - PETG, 100% filling. Gaskets on the upper part of the air filter are needed due to the different heights of the supplied air filters. As a result, a fairly large gap is formed between the top of the air filter and the upper part of the filter housing. These gaskets compensate for this gap and allow you to eliminate the second wing nut inside the filter housing, as well as eliminate the denting of the upper part of the housing when pressed with an external figured nut. An insert in the base of the filter housing is needed if the protrusion for fixing the base of the filter housing on your equipment does not coincide with the cutout in the base of the filter housing: the insert will cover the cutout and allow you to make it in another place or do without a cutout at all. Fasten with cyanoacrylate glue or simply tightly insert into the cutout with good tension. I was unable to set up different materials for different print tables in the Creality Print 6.0 slicer, so use the shared file in *.3mf format only to review all the details. The table names in it reflect the material settings. The exact print settings are in the description and in separate *.3mf files. The last 2 photos - this is what the original filter housing looks like. Due to the curly air supply gap, it is impossible to modify it for remote air intake.
