The sensors are intended for monitoring gas medium composition (carbon compounds, hydrogen, nitrogen, moisture and other gases) in different kinds of industry and an environment.
The sensors allow to register gas concentration in emissive gases with a large degree of selectivity, stability and with a small response time (3-6 s), have a high sensitivity (for example, the restoration period for CO - 10 ppm is no more than 6 s). Units are easily adjusted with a computer.
Economic advantages of the sensor are based on use for its manufacturing mainly resources of Ukraine, group methods of microelectronics, absence of precious materials, low labour input.
Motor transport makes the greatest contribution to the air contamination, in particular the vehicles that have a long exploitation term, that is explained by wearing of engine components and fuel system.The technique of restoring of worn details is designed by drawing wear-resistant composition platings.

The comparative analysis displays, that the technique of restoring of details has a series of advantages over analogues, since it restores the detail geometry, but gives it new anticorrosive and abrasion resistant properties which considerably increase the operation term.
The economic effectiveness of the technique is based on the smaller cost of details' restoring compared with the production of the new ones. Besides it provides engine reliability, power and long operation term, considerably decrease the fuel consumption and atmosphere pollution.
