“…Moreover, the accumulated soot was easily removable and combustible into CO2. Hundleby [18] analyzed the operating strategies to be considered for low emissions, i. e., stoichiometric operation with exhaust gas recirculation and lean burn. For this analysis, natural gas was used as a supplementary fuel.…”

Biodiesel is a renewable alternative fuel that can be used as substitute for mineral diesel. The use of biodiesel in diesel engines reduces all of the exhaust emissions expect NO x . The higher temperature in the combustion chamber increases the NO x emissions. The recirculation of a small percentage of cooled exhaust gases into the combustion chamber through the intake manifold reduces the in-cylinder temperature. Moreover, the cooling of exhaust gases before mixing with fresh air introduced to the engine does not affect its volumetric efficiency but it absorbs the heat of combustion. This leads to a reduction in NO x emissions and improves the engine brake thermal efficiency. This paper describes the investigation of the performance and emission characteristics of a biodiesel-fueled, naturally aspirated, single cylinder diesel engine with cooled exhaust gas recirculation.

“…To overcome this disadvantage, there have been lots of efforts toward fast burning through fuel stratification. Specially, lean combustion system is requested for heavy duty LPG engine to relieve thermal load at the condition of retarded ignition to avoid engine knocking [4,5].…”

“…Typical diesel engines in the 10-12 liters range are turbocharged, with rated speeds around 2100 rpm and achieve BMEP ratings of 14 bar at peak torque and 11.5 bar at rated speed [40]. These ratings are achievable with stoichiometric natural gas engines, but supercharging is required.…”

The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction. In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand corner and continuing from left to right in equal sections with small overlaps. Photographs included in the original manuscript have been reproduced xerographically in this copy. Higher quality 6" x 9" black and white photographic prints are available for any photographs or illustrations appearing in this copy for an additional charge. Contact UMI directly to order.
