To provide an electronic fuel injection type diesel engine capable of miniaturizing the engine.SOLUTION: An electronic fuel injection type diesel engine includes a combustion chamber 2 in a cylinder 1, a fuel injection chamber 4 in a cylinder head 3, a fuel injector 6 for injecting a liquid fuel 5 to the fuel injection chamber 4, a fuel accumulator 7 for accumulating the liquid fuel 5 injected from the fuel injector 6, and an electronic control device 8 for controlling a timing and an amount of injection of the liquid fuel 5. A plurality of fuel injection holes 6b, 6c of the fuel injector 6 are disposed, an injecting direction of the liquid fuel 5 injected from the fuel injection holes 6b, 6c of the fuel injector 6, is directed to an inner surface of the fuel injection chamber 4, the combustion chamber 2 in the cylinder 1 is preferably applied as a main combustion chamber 2a, and the fuel injection chamber 4 is preferably applied as an auxiliary combustion chamber 4a communicated with the main combustion chamber 2a by a nozzle hole 9.SELECTED DRAWING: Figure 1 【課題】エンジンを小型化することができる電子燃料噴射式ディーゼルエンジンを提供する。【解決手段】シリンダ１内の燃焼室２と、シリンダヘッド３内の燃料噴射室４と、燃料噴射室４に液体燃料５を噴射する燃料インジェクタ６と、燃料インジェクタ６から噴射する液体燃料５を蓄圧する燃料蓄圧装置７と、液体燃料５の噴射の時期と量を制御する電子制御装置８を備えている。燃料インジェクタ６の燃料噴射孔６ｂ・６ｃは、複数個設けられ、燃料インジェクタ６の燃料噴射孔６ｂ・６ｃから噴射される液体燃料５の噴射方向は、燃料噴射室４の内面に向けられ、シリンダ１内の燃焼室２が主燃焼室２ａとされ、燃料噴射室４は、主燃焼室２ａと噴口９で連通された副燃焼室４ａとされていることが望ましい。【選択図】 図１
