Purpose – The purpose of this paper is to study the effect of particles on the wear of cylinder liner in internal combustion (IC) engine under some typical weather conditions. Design/methodology/approach – Experiments were conducted under some typical dust weather which was simulated by the self-built test-bed with an actual diesel engine. Three-dimensional surface morphology was applied to produce a comprehensive characterization of cylinder liner's wear. Ferrography and oil spectrum analysis were employed for further understanding of the abrasion of the cylinder liner caused by particles. Findings – The presence of particles destroyed the lubricating condition of piston-cylinder liner, speeded up the wear of liner, especially on the thrust side, and aggravated the local wear. Wear curves showed that greater wear volume occurred near bottom dead center on the thrust side under the dust condition. However, on the anti-thrust side, wear volume of top dead center was greater than that of bottom dead center, similar to the wear pattern under the normal condition. Wear rate under dust condition was three to five times of that under normal condition. Research limitations/implications – The paper is restricted to the experimental findings based on single cylinder engine and theoretical researches are needed in the next step. Practical implications – The results help to understand the wear of the cylinder liner from the presence of particles from outside the engine. Originality/value – The paper concentrates on the effect of dust particles on the wear of cylinder liner under some dusty weather conditions simulated by a self-built test-bed, employing an actual IC engine. The results may bring about better understanding of the wear of cylinder liners. [ABSTRACT FROM AUTHOR] |
