"IMPROVING THE DEVELOPMENT OF A PISTON RING BASED ON SOLID LUBRICANT"

Abstract

"In the article, in relation to the similar conditions of use of internal combustion engines with a crank mechanism and the main indicators of a piston seal having the same design parameters (in particular, cylinder diameter, piston stroke), a comparative assessment of the indicators characterizing their duty cycle and indicator parameters of each of the engines is made (in particular, by the magnitude of the indicator tangential and circumferential force, torque and indicator power). The authors carried out work on the use of sealing in the form of rings with a contact surface based on a solid antifriction material – graphite. It is concluded that, in relation to similar conditions of use, the indicator torques formed during the working cycle of these machines are not equal in magnitude. The indicator torque of the crank mechanism of the engine exceeds the corresponding torque of the internal combustion engine. This conclusion also applies to the ratio of the indicator capacities of the considered thermal machines. Keywords: Internal combustion engine, crank mechanism, working fluid, piston, piston ring, grease."
