| The wear of cylinder kit components of internal combustion engine leads to the increase in blowby and oil consumption and usually determines engine lifetime. Due to the reduced development time, efficient methods for predictive evaluation of engine life are necessary. The paper presents a method of engine lifetime prediction, which takes advantage of the results of test bench engine investigations as well as the results of simulations carried out with the use of the ring pack model of the engine. Ring pack simulations are used for the determination of the boundary wear at which the effectiveness of the pack drops to the permissible level. On the basis of the test bench investigations, the course of engine wear is established. Lifetime is estimated by extrapolating the wear course to the boundary value. The results of example calculations for automotive diesel engine are presented. |
