【実用新案登録請求の範囲】[Scope of utility model registration request] 主燃焼室と副燃焼室とが噴口によって連通されたディー
ゼル機関において、噴口の一部をピストン頭頂部に上下
可動に配置した突起部で構成し、その突起部の下側に、
エンジン温度条件に応じて突起部を上方に駆動する感温
部材を設け、これによって噴口面積を可変としたことを
特徴とするディーゼル機関の燃焼室構造。In a diesel engine in which a main combustion chamber and a sub-combustion chamber are communicated through a nozzle, a part of the nozzle is formed by a protrusion that is movable up and down on the top of the piston, and on the underside of the protrusion,
A combustion chamber structure for a diesel engine characterized by providing a temperature sensing member that drives a protrusion upward according to engine temperature conditions, thereby making the nozzle area variable.
