Biodiesel fuel can be used in diesel engine in accordance to the standard provided. However, a significant issue with biodiesel fuel was noted. Some of the fuel quality were outside the accepted range of the specification stated in the standard. Thus, this can be lead to the problem of utilization them in diesel engine. Moreover, material compatibility is the main concern whenever the fuel composition is altered in the fuel system. A large variety of metals and non-metals are worn as the material of construction for the various components of the fuel system. Introduction of biodiesel fuel often generate many problems in the components of the fuel system. This paper attempts to present the compatibility issue related to the use of biodiesel with automotive materials.

Polycyclic aromatic hydrocarbons (PAH) are pollutants produced during the combustion process and are considered as soot precursors. PAH emissions are not presently regulated although they may have dangerous effects on human health. A comparison is presented here of the influence of engine parameters (air-fuel ratio and brake mean effective pressure) on the composition of par-ticulates. The effects of a water-fuel emulsion on PAH (commonly examined in large engines) are also studied in a 1.9 L commonrail diesel engine: 13 per cent of water added to the fuel decreases the PAH concentration in diesel soot by half. The PAH emissions during cold-start of an automotive diesel engine are also presented.
