In recent years, the human has faced the pollutant emissions from vehicle engines that became a serious environmental problem in the world. Therefore, the targeted developments for future vehicles are how to reduce fuel consumption, pollutant emission while maintaining high level of engine performance. To deal with those issues, Bio-fuel has been greatly considered by scientists for a long period of time. Biodiesel is a renewable fuel produced by a chemical reaction of alcohol and vegetable or animal oils, fats, or greases. Biodiesel can be used as a 20% blend in most diesel equipment with no or only minor modifications. This paper presents summarized findings of utilization of biodiesel with 20% blend (B20) based fish fat in conventional diesel engines. Targeting this, The Mazda WL was used as an object for the application of dual fuels (diesel and biodiesel) conversion. Experimental were tested under standard conditions and part load conditions from 1000 rpm to 3000 rpm, respectively. Exhaust emissions of engine were investigated in this paper. Experimental results indicated that analysis on engine exhausted gas showed the decrease of CO, HC and %OPAC emissions. In addition, the engine using B20 fuel with 10÷30 earlier advance injection timing compared to original one gives better results than the engine used traditional diesel fuel (DO) and B20 fuel without changing the advance injection timing
