Review of the state-of-the-art of exhaust particulate filter technology in internal combustion engines.

The gradual decline in global oil reserves and presence of ever so stringent emissions rules around the world, have created an urgent need for the production of automobiles with improved fuel economy. HEVs (hybrid electric vehicles) have proved a viable option to guaranteeing improved fuel economy and reduced emissions. The fuel consumption benefits which can be realised when utilising HEV architecture are dependent on how much braking energy is regenerated, and how well the regenerated energy is utilised. The challenge in developing an HEV control strategy lies in the satisfaction of often conflicting control constraints involving fuel consumption, emissions and driveability, without over-depleting the battery state of charge at the end of the defined driving cycle. As a result, a number of power management strategies have been proposed in literature. This paper presents a comprehensive review of these literatures, focusing primarily on contributions in the aspect of parallel hybrid electric vehicle modelling and control. As part of this treatise, exploitable research gaps are also identified. This paper prides itself as a comprehensive reference for researchers in the field of hybrid electric vehicle development, control and optimisation.

Particulate emissions from biodiesel fuelled CI engines

Biodiesel fuels derived from a variety of plant and animal feedstocks are promising renewable alternative diesel fuels in view of energy security, environmental protection and the great potential of carbon dioxide (CO 2 ) reduction from the whole cycle of biodiesel production. This review only focused on the characteristics of oxides of nitrogen (NO x ), particulate matter (PM) and polyaromatic hydrocarbon (PAH) emissions found in recent years when various biodiesel fuels with different physicochemical properties were used in diesel engines. The effect of ethanol addition, exhaust gas recirculation (EGR) and various catalytic converters on the emissions above and particle size distributions of diesel engines was presented. To meet stringent exhaust emission regulations when biodiesel is used, efforts on engine electronic control systems, the improvement in conversion efficiency of catalysts, particulate trapping efficiency and biodiesel preparation require to be made.
