| Abstract | ||||
| The aim of recent research work is to investigate a case study on wear in some basic parts concentrated on the piston with oil-sealing rings, suction and exhaust valves and its guides. Some parts of the engine have been taken; piston engine and its rings (pressure and oil rings). Which was changed after 10 years at a rate of 3 hours of daily operation. A test (setting wear rate and friction coefficient) was performed for both the metal of the anti-slip rings oil as well as the inner part of the engine cylinder. The results proved that the rate of ring wear is greater than the rate of wear of the cylinder as well as the experiments showed the importance of lubrication in the engine since the results in the case of the sample after lubrication showed less wear rate than the dry sample without lubrication. The axial adjustment test was performed on a suction valve as well as an exhaust valve in the guide of each valve to determine the effect of deterioration after 10 years. The results showed that the exhaust valve was bent with 1º 40’ and the suction valve at 2° 20'. American Mechanical Engineering allows one degree in the case of rotary columns and three degrees of inclination in fixed columns as in the case of the sample. | ||||
