To help understand the complex fuel spray combustion phenomena in modern diesel engine using high injection pressure, a fuel injection test bench and a constant volume combustion chamber were developed and demonstrated in this study for diesel spray diagnostics. Both facilities are significant when linking between spray injection and combustion dynamics and engine performance. This link is impo...

A continuous process for the transesterification of triglycerides to methyl esters was investigated in a pilot plant. The process was equipped with a motionlerr and a high-shear mixer. The experimental studies explored variations in the mixing intensity, stcichionetry, and catalyst concentration on the overall conversion. The combined as well as individual effect of mixers was examined. The dev...

Compression Ignition (CI) engines are widely used for transportation, agriculture, power generation and industrial applications. The conventional fuel for CI engine is petro diesel. Among the countries in the world, India is one of the largest consumers of petro diesel fuel. Indian economy is very much dependant on the consumption of petro diesel. Brake thermal efficiency, brake specific fuel c...

– The rapidly depleting conventional petroleum resources have promoted research for alternative fuels for internal combustion engines. Among various possible options, fuels derived from triglycerides (vegetable oils/animal fats) present promising ‘‘greener’’ substitutes for fossil fuels. Vegetable oils, due to their agricultural origin, are able to reduce net CO2 emissions to the atmosphere alo...

Air pollution is one of the major issues about the diesel engines in todays' world. It is a special concern in those areas that have difficulty meeting health-based outdoor air quality standards. Natural gas has low emission and resource abundance and also conventional compression ignition engine can be easily converted to a dual fuel mode to use natural gas as main fuel and diesel as pilot ...

The main objective of the research is to compare the accurateness of Artificial Neural Networks (ANN) and Multiple Linear Regressions (MLR) model for Specific Fuel Consumption for pyrolysis oil blended with diesel used in a single cylinder diesel engine. In this study, parameters i. e. Injection Timing, Injection Pressure, Compression Ratio, and Load are taken. Artificial Neural Networks (ANN) ...

It was suggested in a previous study that cells of Acinetobacter venetianus VE-C3 adhere to diesel fuel by synthesizing a capsular polysaccharide containing glucose and/or mannose. To study the fine structure of cells and localization of bacterial polysaccharide in the presence of diesel fuel, two lectins were used: ConA, an agglutinin from Canavalia ensiformis specific for mannose and/or gluco...

The objective of this paper is to investigate the effect of fuel injection pressure on power performance and fuel consumption of diesel engine. In a diesel engine, fuel injection pressure is an important aspect of the engines’ power performance in order to obtain combustion treatment. The experiments in this paper are performed on a four-cylinder two-stroke direct injection diesel engine. The d...

Biodiesel is one of the most promising alternative diesel fuels. As diesel emission regulations have become more stringent, the diesel particulate filter (DPF) has become an essential part of the aftertreatment system. Knowledge of kinetics of exhaust particle oxidation for alternative diesel fuels is useful in estimating the change in regeneration behavior of a DPF with such fuels. This study ...
