This article provides brief information about the new design of the dry piston seal in the cylinder and the results of an experimental study of this design. It was found that the resource is more than 3 thousand hours. In fact, the standard seal has about the same resource. But there are differences in the operation of the standard seal and the developed dry seal. A dry seal throughout the entire service life ensures density and changes in the technical and economic indicators of the engine due to the operation of the piston seal should not occur. It should be noted that in this work, the first stage of mastering the dry seal design has been completed. Next, the economic effect of using a dry seal is calculated. First, the annual operating costs for items related to the cylinder-piston group of the engine are determined. The total annual savings will amount to 74,518 tenge per year.  Taking into account the payments for services at the service station, the annual savings can amount to 100-150 thousand tenge per year. Consideration of the technical results and the economic effect of using a dry piston seal in the cylinder shows that according to these indicators, the developed seal design has great prospects.
