Effects of biodiesel usage on mechatronic components in automobiles with diesel engine: A review

The extinction of petroleum-based fuel resources and reducing regulations of the environmental pollution compel engine manufacturers and researchers to develop alternative fuels and high-performance engines. New generation diesel engines developed in recent years; equipped with high-pressure injection systems, modern dispenser pumps, and improved injectors. The use of alternative fuels in this new generation of mechatronic systems is also an issue examined by researchers. During engine operation, biodiesel, one of the renewable alternative fuels, can cause reduced engine performance, heavy carbon and varnish deposits in mechatronic components, and actual damage to the engine. In this study, mechatronic systems constituting engine management system are introduced. The effects of biodiesel usage on new generation diesel engines with the common rail injection system are investigated and the problems encountered in the use of biodiesel are evaluated.
