PERFORMANCE OF DIESEL ENGINE FUELLED WITH FOUR VEGETABLE OILS, PREHEATED AND AT ENGINE WORKING TEMPERATURE

ABSTRACT With the rise of restrictions imposed by law for gases emission, several technologies both for petrodiesel (PD) or diesel engines are been applied, such as the sulfur reduction and the injection electronic command, followed of gases recirculation and/or after-treatment. The utilization of biofuels is considered as an interesting option for pollutants reduction. In this study was evaluated the performance on short duration tests (minor period than the factory indication of the lubricant lifespan) of the Diesel engine fueled with four vegetable oils. With the aim to select the most inte...
