Experimental Investigation on IC Engine using Alternate Fuels for Material Compatibility of Piping and Fitting system

In the present time the entire world is worried about the impact of condition contamination and the emissions from vehicle as a result of utilization of petroleum product is considered as a noteworthy commitment to it. Biodiesel is turned out to be the best trade for diesel as a result of their excellent eco-friendly properties. Even though the biodiesel is considered as a better fuel than the fossil fuel, the automobile sector is not ready to accept biodiesel because of less research related to compatibility of materials with the biodiesel. This lags in the implementation of completely biodiesel engine in automobiles.

This research work is mainly focused on the experimental investigation to study the effect of biodiesel on elastomeric materials used in automobiles and to suggest suitable material in that field which is having higher compatibility with the biodiesel. The methodology involves immersing the elastomeric materials like NBR, CR, EPDM, Silicone and Natural Rubber into the biodiesel and evaluating mechanical behaviors immersed at 250hrs. The experiments shows that the suitability of elastomers for biodiesel is NBR > CR > EPDM > Silicone > Natural rubber. (paper)
