Abstract
SUGRE (Sustainable Green Fleets) Intelligent Energy - Europe (IEE) Project promotes alternative propulsion (ranging from bio-fuels, methane as fuel to hybrid systems comprised of internal combustion engines and electric propulsion systems) on both commercial/captive fleets and private fleets trough dissemination of experiences and good practices in relation to alternative fuels and alternatively propelled vehicles (AF&APV). SUGRE will generate a positive attitude towards alternative fuels and new power train concepts using captive fleets as forerunners and as proof for the viability of alternative propulsion.
The main objective of the project is to promote and support the conversion of fleets to alternative propulsion. The campaigns will address the public and stakeholders, communicating enabling factors for AF&APV and increasing the visibility of APV and fleets running on alternative fuels.
Thus, SUGRE aims to increase the share of AF&APV in Europe´s captive fleets, reduce the share of fossil oil derived fuels in Europe´s transport, and use the transition to AF&APV to reduce road near emissions. SUGRE will closely monitoring and evaluate the results of the actions for all the activities, i.e. inclination, knowledge and expertise, but also facts of AF usage and APV sales.
One of the most perspective paths regarding the alternative fuels encompassed with SUGRE is the hydrogen application. Bulgarian hydrogen application research experience as addition of hydrogen to the gasoline-air mixture for vehicle engines is the subject of the present paper. There are presented the design of an advanced combustion system for Hydrogen Enhanced Torch Ignition (HETI), manufactured in the Laboratory on ecological problems of engines (LEPE) of the University of Rousse (RU), and results for about 15-20 % economy of gasoline effect, decreasing of CO and total content of NOx, etc.
