PURPOSE:To prevent an outflow of jetted air, by forming a partition between a flow inlet of air and a flow outlet of combustion gas in a combustion chamber of a gear internal-combustion engine in which an even number of at least four operative gears are annularly arranged and meshed to one another. CONSTITUTION:Six operative gears are annularly arranged and supported to an operative gear case 7 so as to be meshed with one another. (The principal part is shown in thd drawing). A heat insulating base metal 18 is embedded to a location at a face-to-face position to an externally faced meshing point Go in the rear wall face of a combustion block 14, and a spherical combustion chamber 20 is formed between the base metal and the combustion block 14. To prevent jetted air from immediately flowing out to the outside of the chamber 20, a partition 63 is formed between a flow inlet 61 of air and a flow outlet 62 of combustion gas in the chamber 20. Further existence of the partition can surely mix fuel with air, and an air excess factor is decreased while an output of an engine can be increased. |
