combustion processes - Opis:
- An aim of work was analysing of combustion and ignition processes in chambers with small volume at the use of different sorts of fuels, fuel liquid and air mixtures and fuel gas ones. For experiments, the machine of single compression the cubic capacity of 400 mm3 approx and average piston speeds 4 m/s was used. Investigated physical processes allowed better recognizing processes occurring in miniature- real engines. For the feeding of the machine of single compression, homogeneous mixtures of hydrogen with air, propane with air and mixtures methyl and ethyl alcohol in the stoichiometric relation with air were used. Adequately earlier prepared mixtures warranted the repeatability conditions of the experiment. Experiments effected with the machine of single compression showed small increases of pressure from combustion process. The occurrence this can be explained with significant heat conduction to walls during comparatively long compressing and combustion. In carried research with the machine of single compression with very large ratio surface combustion chamber to its volume, one obtained comparatively low value of the maximum compression pressure. The researches showed that on processes of compression, combustion and ignition, the greater influence had geometry of combustion chamber, average piston speed than sorts applied fuels.
