The influence of particle filter regeneration on oil consumption in euro 5 Diesel Engine

Abstract The transport sector is a significant contributor to air pollution through the concentrations of emissions contained in the road vehicles flue gases. Although the implementation of EURO standards and the use of modern de-pollution technologies have greatly contributed to the reduction of these emissions, the concentrations of pollutants in the atmosphere are still high. In this context, the paper analyses the cases in which the stability of the de-pollution system indirectly influences the oil consumption during the operation of a EURO 5 diesel engine fitted to an M1 car, which is caused by its improper operation. Thus, oil consumption is analyzed according to the degree of particulate filter blockage and its influence on engine performance. The results of the study showed that new technical solutions are needed to improve the stability of the engine operation. These solutions also lead to a reduction in the pollution generated by the car operation.
