Application of jacket cooling water system recovery for fuel heating on diesel engine to reduce emissions

Abstract

The existence of a diesel engine is very necessary for life today. In development, the diesel engine is experienced many developments in all systems. In line with the development of the diesel engine can’t be separated from the impact of fuel use. This research was carried out to make a fuel heating system by utilizing jacket cooling water system recovery as a fuel heater and the method used in this research is an experimental method including making installation of a fuel heating system, testing on the diesel engine generator with specifications 4 strokes, 4 cylinders, 1500 rpm, 18 kVA using biodiesel (B20) fuel. The data were collected using a smoke opacity meter. The experiment was carried out by heating treatment of fuel starting from 30°C - 50°C at the interval of 5°C. Data analysis by describing experimental data. The result is showed that heating fuel can reduce the emission of the diesel engine.
