- The latest intensive researches are directed on advanced low-temperature combustion (LTC), homogeneous charge compression ignition (HCCI), pre-mixed charge compression ignition (PCCI), reactivity controlled compression ignition (RCCI) and lean-burn petrol are presented in the paper. Engines with the direct injection of petrol (GDI) and Common Rail are subject of the paper. Engines the Scuderi and Holubowicz are described. The schema of Scuderi of engine is introduced. The original model of the combustion process is presented. Combustion rate at occurring of convection, velocity components of gases of liquid fuels changes combustion processes of these fuels. Increasing of velocity of the gas stream always increases the combustion rate, whereat the character of the influence is relative to the kind of the flow, which can be laminar, transient or turbulent. For the purpose of the comparison of experimental findings, one carried out calculations with the use of the modelling. In the modelling one used the ANSYS FLUENT programme which creates the opportunity of the modelling of the wide range of problems connected with the computational flow dynamics (CFD), both in reference to the flow of compressible fluids, as and incompressible, laminar and turbulent flows, phenomena of the transport, the heat exchange, with the occurrence and without the occurrence of chemical reactions. The field of the speed for the module from two velocity components introduced for the laminar and turbulent flow is presented.
