THEORETICAL DETERMINATION OF OPTIMUM CONSTRUCTIVE PARAMETERS OF COMBUSTION CHAMBERS OF SMALL SIZE MARINE DIESEL
One of the sub problems on improvement of internal mixture formation quality is a determination of combustion chamber optimum parameters providing intensive eddy formation, absence of flaw formation in borders, active evaporation of fuel film from chamber walls. First of all, it concerns combustion chambers, located in pistons, in particular, cylindrical combustion chambers. The example of theoretical calculation of the main geometric parameters of the cylindrical combustion chamber with reference to conditions of mixture formation of high speed diesels of the type 2F 9.5/11 depending on the accepted dispenser of perforated injectors. It was stated that to get high fuel efficiency and error-free performance volumetric film mixture formation can be used in cylindrical combustion chamber in piston with vertical walls and absorption based eddy motion of air charge round the cylinder axle.
