Triacylglycerols produced by plants are one of the most energy-rich and abundant forms of reduced carbon available from nature. Given their chemical similarities, plant oils represent a logical substitute for conventional diesel, a non-renewable energy source. However, as plant oils are too viscous for use in modern diesel engines, they are converted to fatty acid esters. The resulting fuel is ...

In this research, back-propagation (BP) and generalized regression (GR) GR neural networks are developed for predicting the performance and emissions of direct injection diesel engine fuelled with the mixtures of diesel and castor oil fuels. The neural network models for the engine were trained by using some of the experimental data. Experimental test are carried out on a semi-heavy duty Motors...

EXTENDED ABSTRACT Commercial marine vessels range in size from small fishing boats (20-30 meters in length) to extremely large tanker ships (>300 meters in length). These ships almost without exception use diesel engines for propulsion and auxiliary power generation. The larger ships, comprising bulk carriers, tankers and container carriers, utilize slow-speed diesel (SSD) engines that produce ...

The conversion of biomass to energy (also called bio energy) encompasses a wide range of different types and sources of biomass, conversion options, end user applicationsand infrastructure requirements. Mustard oil biodiesel performed very well in vehicles. Fuel consumption increased compared to fossil diesel because biodiesel has slightly less energy per gallon than diesel fuel. The fuel filte...

This paper investigates the opportunity of using almond oil as a renewable and alternative fuel source. Different fuel blends containing 10, 30, and 50% almond biodiesel (B10, B30, and B50) with diesel fuel (B0) were prepared and the influence of these blends on emissions and some performance parameters under various load conditions were inspected using a diesel engine. Measured engine performa...

Application of Compressed Natural Gas (CNG) in diesel engines has always been important, especially in the field of automotive engineering. This is due to easy accessibility, better mixing quality and good combustion characteristics of the CNG fuel. In this study the application of CNG fuel along with diesel oil in a heavy duty direct-injection automotive diesel engine is experimentally investi...

Biodiesel is one of the promising renewable, alternative and environmentally friendly biofuels that can be used in diesel engine with little or no modification in the engine. In the present study an experimental investigation has been carried out on the combustion and performance characteristics of a CI engine running with biodiesel under steady state operating conditions. The experimental work...

A pyrolysis study on a species of brown algae Saccharina japonica was carried out in a fixed-bed reactor. The yields of bio-oil and bio-char obtained at 450 C were 47 % and 33 %, respectively. The raw S, japonica, ethanol and acid pretreated samples and the resulting pyrolysis products were also characterized with respect to proximate and ultimate analysis, and higher heating value. The crude b...
