Series: Marine Engineering and Technologies %D 2010 %I Astrakhan State Technical University %X The methodology of analytical calculation of coupling resource "cylinder sleeve ¨C upper compression ring" is offered according to the expected values of its wear for ship small-sized diesel engines. The base of the calculation is sta-tistical material for tractor engines of close dimensionality and having similar physical and mechanical characteristics of components materials of the cylin-der-piston group. %K resource %K wear %K wear rate %K compression ring %K cylinder sleeve %K nominal values %K medium operating values %K abrasive particles %K chemical composition of cast irons %K hardness. %U http://astu.org/content/userimages/file/sea_2_2010/19.pdf
