Distribution of metallic particles and other hard impurities in lubrication system and exhaust system of combustion engine 2000-05-0052
One of the most important utilization features of vehicle engine
is its durability. Durability depends mainly on the wearing
processes of frictional connections of engine elements.
The studies of engine parts wearing can be divided into two
kinds: quantitative and comparative according as the purpose is to
define quantitative durability or comparison of the influence of
selected design, technological and utilization factors.
The present report describes distribution of metallic impurities
coming from mechanical wear of parts in the combustion engine.
Distribution of impurities between lubricating system and exhaust
system is of nonlinear character. High nonlinearity appears in not
fixed conditions of the engine. In the longer time interval of
engine operation, the distribution proportions between oil, oil
filter and exhaust gases are going to stabilize. The knowledge
about impurities distribution process in the engine enables
improving the tests of engine parts mechanical wear and the tests
of oil filtration process in the engine.
