The Influence of NaCl dissolved on biodiesel of used cooking oil on performance and its degradation of main components of diesel engine

Abstract

Biodiesel has been developed both domestically and abroad. Various studies have been conducted to determine the feasibility and capability of raw materials used cooking oil is replacing diesel oil in the future. The salt content in the raw material for biodiesel (new cooking oil and used cooking oil) could have a negative impact or even do not have a significant effect on the rate of wear of metal on the main components of the diesel engine. Through durability tests, the effect of salt (NaCl) on the main components of diesel engines has been tested. The new cooking oil biodiesel is used as a reference in examining the damage level of the main components of diesel engines. Results of the experiments showed that there is a difference between the use of biodiesel fuel from used cooking oil with new cooking oil such as lower diesel engine performance, carbon deposits generated higher, and degradation of metal elements on the main component in the diesel engine lubricating oil is higher
