The air filter can be made of tin, and the carburetor can be sorted out without turning off the engine …

The first GAZes inherited from Ford the most simplified power supply system without an air filter. The dust of domestic roads quickly clogged the carburetor, penetrated the engine, "killing" the cylinders and piston rings. Savvy drivers built on their GAZ-A and one and a half lorry a simple, but, as practice has shown, a fairly effective air purifier (see. Fig.).

A curved pipe was attached to the suction port of the carburetor, and on top of it was a metal box with holes drilled from above, from the side, and from below. Inside the box on two racks a small impeller was mounted. It, rotating in an air stream, "caught" dust and sand and threw them to the sides. Part of the dirt flew out through the side openings, and heavier particles rolled down to the lower ones along the inclined bottom.

The angle of inclination of the wings was determined, of course, empirically, and with the fact that an obstacle not provided for by the construction stood in the way of the air, they put up. But the dust really got less.

Nevertheless, it was necessary to clean and adjust the carburetor very often. Sometimes the driver was forced to repair the device in the field. In winter, in severe frost, while he was busy with the power supply system, the water in the engine often already “caught”. In order not to turn off the engine, the garage inventors equipped their cars with an additional mini-carburetor. A self-made nozzle with a tap was inserted into the intake manifold. Gasoline came to her by gravity from the tank that was fixed in the upper part of the engine compartment. A simple device provided the engine with a frequency of 200-300 rpm. When the repair was completed, the supply of gas to the auxiliary carburetor was shut off.
