Abstract
We have studied the effect of chemical composition of
biodiesel fuel on the physical (volatility) and chemical (reactive oxygenated
species concentration) properties of nano particles emitted from a modern
common-rail diesel engine. Particle emissions from the combustion of four
biodiesels with controlled chemical compositions and different varying
unsaturation degrees and carbon-chain lengths, together with a commercial
diesel, were tested and compared in terms of volatility of particles and the
amount of reactive oxygenated species carried by particles. Different blends
of biodiesel and petro diesel were tested at several engine loads and speeds.
We have observed that more saturated fuels with shorter carbon chain
lengths result in lower particle mass but produce particles that are more
volatile and also have higher levels of Reactive Oxygen Species. This
highlights the importance of taking into account metrics that are relevant
from the health effects point of view when assessing emissions from new
fuel types.
