Abstract
This paper presents a literature review on use of alternative fuels in road
transport, in respect of their performance and emission in diesel engines/vehicles.
The major limitations of vegetable oils as fuel in diesel engines are their high
viscosity and poor volatility, which lead to severe engine deposits, injector coking,
and piston ring sticking. Transesterification reaction reduces the viscosity of
vegetable oils, and the result of this reaction is biodiesel. In general, engine power
dropped due to the lower heating value of biodiesel. A proper injection timing, by
advancing the start of fuel injection by 1-2°BTDC, determined that all changes in
engine emission are according to chemical and physical properties of the tested
fuels.
