Abstract
The technical possibility of decreasing engine emissions and fuel consumption in relation to the increase in the usable engine parameters has been presented in the paper. The above problem relates to the dynamic and kinematic properties of airflow into the combustion chamber. The effect of swirl in the intake manifold that refers to the achieved engine operating parameters and emission level was presented in the paper. The included results of the experimental research of airflow swirl in the air intake model allowed getting answers related to the issues of flow resistance. The analysis of literature and the analysis of the modeling results led to conclusions about the theoretical and practical possibilities of flexible intake duct implementation.
Highlights
The growth in the engine efficiency is a priority when designing modern engines while still working on the reduction of the negative impact on the environment
One of the most important objectives in engine design is the reduction of the fuel consumption and meeting the ever more stringent emission requirements while still maintaining the high usable parameters of the engines

Summary
The growth in the engine efficiency is a priority when designing modern engines while still working on the reduction of the negative impact on the environment. Alternative fuels as a source of energy for modern combustion engines are being improved on a continual basis in terms of quality and engine operating parameters This should allow an efficient use of these fuels that come from renewable sources. Bezpośrednim rezultatem tych zabiegów oddziaływujących na proces przygotowania mieszaniny palnej oraz jej spalania jest uzyskanie małego zużycia paliwa oraz niskiego poziomu emisji składników the parameters of the charge flow to the working area allows szkodliwych spalin przy równoczesnym wzroście a high repeatability of the combustion process. Autorzy badań są the heat exchange process [2, 4, 11] and the stabilization zgodni w tym, że dzięki zawirowaniu typu „swirl” uzyskuje of the combustion processes [5] The results of these się poprawę efektywności procesu spalania określaną przez investigations in a different way present the influence of uzyskanie bardziej homogenicznej mieszanki paliwowo-pothis swirl.
