car ZIL-131

The presence of a tire pressure regulation system on a car allows you to:
- a) increase the vehicle’s cross-country ability on difficult sections of the road by reducing the specific ground pressure by changing the tire pressure;

The pistons (Fig. 1) are made of aluminum alloy and coated with tin.
The piston skirt has the shape of an elliptical cone, the large base of which is located at the lower edge of the skirt, and the largest axis of the ellipse lies in the plane perpendicular to the axis of the piston pin.

The vehicle's electrical system is single-wire, with a nominal voltage of 12 V; the negative terminals of the current sources are connected to the body ("vehicle ground")
