As an alternative fuel biodiesel can be played an important role to meet the future energy demand. Biodiesels have lot of good advantages over diesel which attract the users to use it as the substitute of diesel. It has huge biodegradability, less environmental impact, higher flash point and cetane number, higher lubricity and so on. However, for the widespread practical applicability of biodie...

The U.S. Environmental Protection Agency (EPA) established strict regulations for highway diesel engine exhaust emissions of particulate matter (PM) and nitrogen oxides (NOx) to aid in meeting the National Ambient Air Quality Standards. The emission standards were phased in with stringent standards for 2007 model year (MY) heavy-duty engines (HDEs), and even more stringent NOX standards for 201...

Fossil fuels are the most imperative parameters to flourish the every sphere of modern civilization including industrial development, transportation, power generation and easing the accomplishment of works. The rapid increase in usage of fossil fuel has unavoidable deleterious effect on environment. The international consciousness for environment protection is growing and ever more strict emiss...

Present energy situation of the world is unsustainable due to unequal geographical distribution of natural wealth as well as environmental, geopolitical and economical concerns. Ever increasing drift of energy consumption due to growth of population, transportation and luxurious lifestyle has motivated researchers to carry out research on biofuel as a sustainable alternative fuel for diesel eng...

Biodiesel is a green fuel produced from renewable resources. It is a clean-burning alternative fuel, which has drawn the attention of energy researchers for the last two decades. This paper presents an experimental investigation on Alexandrian laurel oil as a potential feedstock for biodiesel development. Biodiesel was produced using a two-step esterification–transesterification process. Analys...

Diesel engines being inferior in their emission characteristics are under greater scrutiny. Intensive research efforts are ongoing for improving fuel consumption and exhaust emissions from diesel engines. For improving performance of engine, Ceramic based Thermal barrier Coating plays a major role. Tests were performed on four stroke, single cylinder, DI diesel engine whose piston crown, cylind...

Biodiesels are gaining more importance as a promising alternative energy resource. Engine performance and emission characteristics of unmodified biodiesel fueled diesel engines are highly influenced by its ignition and combustion behavior. This review article presents the literature review on ignition delay (ID), combustion and emission characteristics of biodiesel fueled diesel engine. More th...

In this paper, a computational in-cylinder analysis of HCCI diesel engine was carried out using IC Engine FORTE (ANSYS 18.2) software package. The analysis used pre-defined industry standard CHEMKIN format for specifying a chemical reaction mechanism during the combustion duration. The investigation was carried out for the effects of various EGR mass percentages on the thermal and emission char...

One of the important problems in reducing of pollutant emission from DI and IDI diesel engines is trade-off  between soot and NOx. Split injection is one of the most powerful tools that makes the chance to shift the trade-off curve closer to origin.  At the present work, the effect of split injection on the combustion process and emissions of a cylinder IDI diesel engine under the specification...

Diesel engine emission standards are being more stringent as it gains more publicity in industry and transportation. Hence, designers have to suggest new controlling strategies which result in small amounts of emissions and a reasonable fuel economy. To achieve such a target, multi-objective optimization methodology is a good approach inasmuch as several types of ...
