Supplementary combustion equipment of diesel engine

Abstract

Abstract PURPOSE:To improve combustion of an engine by detecting a combustion temperaure from the resistance of a glow plug even during engine run and heating the mixture in a combustion chamber for a certain period by means of the glow plug when the combustion temperature is reduced. CONSTITUTION:A voltage developed across a glow plug 1 is inputted into a comparator 12 and compared with a specific voltage to estimate the combustion temperature by means of a resistance of the glow plug 1. When the resistance is reduced below the specific value, the comparator 12 triggers a timer 14 to turn on a glow relay 9 via an output device 15 in order to raise the temperature inside the combustion chamber. Thereby, combustion of a diesel engine may be improved.
