The article discusses the results of the wear of piston rings for internal combustion engines with spark ignition. The research was a prototype multilayer ring sealing of the porous coating and the so-called chromium embankment diamonds. Technology of the rings is the deposition of multilayer coatings in the process of chromium plating. In times of chromium deposited from the bath, particles are technical diamond's shape, and granulation. This technology is a response to domestic factory piston rings to the needs of the automotive market and is an innovative development. Conducted engine tests consisted of a 50-hour cycle and to hour break-in team life cycle, which was repeated 150 times. Thus, the total duration of sample equal to 200 hours. Cycle life is a team containing a phase-hour cycle engine traffic load at maximum speed and maximum torque and maximum power of the tween partial load and idling. This cycle is repeated in the 200-hour test 150 times. During the measurement of key indicators were measured at the engine, the fuel consumption, coolant temperature and pressure of the lubricating oil. In order to calculate the wear of piston rings, the difference was calculated to measure the thickness and height before and after sample of 200 hours. In a similar way as the use of thickness and height of the rings was calculated by weight loss.
