Evaluation of the Environmental and Operating Parameters of a Modern Compression-Ignition Engine Running on Vegetable Fuels with a Catalytic Additive

This article discusses the possibility of using a liquid catalyst in selected vegetable fuels. The fuels selected for study are rapeseed oil methyl ester and hemp oil methyl ester. The aim of the research presented in this paper is to evaluate the operating and environmental performance of an engine fueled with selected fuels with a catalytic additive. The tests were carried out on a dynamometer bench using a Fiat 1.3 JTD common rail engine. During the tests, parameters such as engine torque and power, specific fuel consumption, and the emission of nitrogen oxides, hydrocarbons, carbon dioxide, and soot were measured. The tests were carried out on fuels with and without a catalytic converter. The results show that the use of a catalytic additive reduces nitrogen oxides and hydrocarbon emissions for all fuels tested.
