Abstract

PURPOSE:To improve combustion efficiency, by setting an electrode in a combustion chamber, connecting the electrode and the wall of the combustion chamber to an electric power source, and generating the electric field in such intensity as not to cause a spark discharge in the combustion chamber, thus reducing carbon particles and the like produced from incomplete combustion. CONSTITUTION:An electrode 4 is provided in a combustion chamber of a cylinder head 1 to apply a potential difference between the electrode 4 and a wall of the combustion chamber by a power source 5. If voltage is applied by the power source 5 to such a level that a spark discharge is not caused, the electric field can be generated in the combustion chamber to increase ions in flame. If the ions are increased, condensation nucleuses are increased, and grain size of particles is decreased, then combustion in the combustion chamber can be promoted. In this way, combustion efficiency is improved, and carbon particles and the like produced by incomplete combustion can be decreased.

Description

【発明の詳細な説明】 本発明は、燃焼室内に設けたディーゼルエンジンの燃焼

とができる構造になっている。The present invention will be described based on an embodiment. In a normal diesel engine having a cylinder head 1, a piston 2, and a cylinder 3, an electrode 4 is provided in the combustion chamber of the head 1, and a power source 5 connects the electrode 4 and the head 1. Piston 2.
The structure is such that a potential difference can be applied between the cylinder 3 and the combustion chamber wall.

を増加させる。Next, to explain the operation of the embodiment of the present invention, from the start of fuel injection to the time of flame extinction, the power source 5 connects the electrode 4 to the head 1, which is at the installed potential. When a voltage of up to about 10 KV, which does not cause spark discharge, is applied to the darkness of the piston 2 and cylinder 3, an electric field is created within the combustion chamber, and this electric field increases the number of ions in the flame.

する。Ions in the flame become condensation nuclei of hydrocarbons during the process of fuel combustion and decomposition, so as the number of ions increases, the number of condensation nuclei increases, and the particle size of particles generated by the condensation nuclei increases. Since the fuel becomes smaller, combustion within the combustion chamber is promoted, re-burning is also promoted, improving combustion efficiency, and carbon particles etc. produced as a result of incomplete combustion are reduced.
