燃料騒音を低減することを特徴とするディーゼルエンジ
ンの燃焼騒音低減装置。It is supported by the cylinder head, the tip of which protrudes from the cylinder head, exists in the combustion chamber of the cylinder in parallel with the injection nozzle tip, and the tip includes a center electrode and a ground electrode that are electrically insulated and are opposed to each other in the longitudinal direction. A piezoelectric element whose one end is connected to both electrodes in sequence by a lead wire, and a nail-shaped iron core which is opposed to the other end of the piezoelectric element at one end and has an electromagnet disposed near the head of the other end and is loaded with an elastic force. The piezoelectric element is pressurized by the iron core through the electromagnet by computer-controlled current through fuel injection timing, load, and rotation sensors, and the piezoelectric element is pressurized by the piezoelectric effect of the piezoelectric element. A combustion noise reduction device for a diesel engine, characterized in that a spark is generated between the center and ground electrodes of a spark plug to ignite fuel, shorten ignition delay, and reduce fuel noise.
