О целесообразности применения аустенитного марганцовистого чугуна для седел клапанов ДВС, работающих на газомоторном топливе

Abstract

В статье рассматривается вопрос о необходимости и целесообразности применения аустенитного мар-ганцовистого чугуна для седел клапанов ДВС, эксплуатирующихся на газомоторном топливе. Приводят-ся сведения о серийно выпускаемых седлах клапанов ДВС автомобилей, описываются наиболее распро-страненные сплавы для изготовления деталей седел, их недостатки, несовершенство сплавов, применяе-мых при эксплуатации, и причины низкого ресурса деталей такого типа. В качестве решения данной проблемы предлагается использовать аустенитный марганцовистый чугун. На основе многолетних ис-следований свойств марганцовистого чугуна было предложено использовать данный сплав для изготов-ления седел клапанов автомобильных двигателей с газомоторным топливом. Рассматриваются основные свойства, которыми обладает предлагаемый сплав. Результаты исследований положительные, а ресурс новых седел по сравнению с серийными в 2,5 … 3,3 раза больше.

The article discusses the need for and feasibility of manganese austenitic iron valve seats for ICE operated on mo-tor fuel. Provides information about commercially available valve seats ICE vehicles, describes the most common alloys for manufacturing parts of saddles, their flaws, imperfections in the alloys used in the operation of, and reasons for the low resource items of this type. As a solution to this problem by using manganese austenitic iron. Based on years of research on the properties of manganese iron was suggested to use this alloy for the manufac-ture of valve seat car engines with gas motor fuel. The basic properties, which has proposed alloy. Research results are positive, and the resource of new seats compared with serial 2,5... 3,3 times more.
