高速度写真による予燃焼室式ディーゼル機関内燃焼の研究 : 第2報, 主燃焼室内燃焼

Using a high-speed motion picture camera, the authers made flame photographs thraugh a glasswindow set on the cylinder head of a pre-combustion type Diesel engine. For the cases of various ejecting directions and also for the various forms of cavity on a piston crown, the process of mixing and combustion of the gas mixture blown out from the pre-combustion chamber, swirl creation and flame distribution in the cylinder were investigated. Further, the suitable design of the main combustion chamber for improvement on the combustion was discussed by comparing the results of performance test obtained in a single cylinder engine.
