The new effective implicit schemes of a large particles method not requiring additional iterations on computational step are offered. The analytical expression of intermediate pressure at an Euler stage lays in the basis of the schemes. The results of calculations with the help of the offered schemes were compared with calculations by traditional schemes. They were compared also with results of special experiment simulating a separated flow through windows of a two-cycle engine of internal combustion. The advantage of the new schemes on accuracy of calculation and on expenditures of run time is shown. The examples are given of practical using the new schemes for optimization of profiles in gasair channels of engines. That has improved noticeably their technical and economic parameters, e.g. fuel efficiency.
