Vegetables oils are simplest route of biofuel utilization in direct injection compression ignition (DICI) engines however several operational and durability problems are encountered while using straight vegetable oils in CI engines due to their high viscosity and low volatility. Reduction of...

Amongst primary alcohols, butanol is considered as the most promising alternative fuel candidate because of its favourable chemical and physical properties, which are quite similar to gasoline. Butanol is completely miscible with gasoline in any proportion and forms a stable blend. It is not...

The purpose of this study is to investigate the effects of various engine conditions on the combustion, flame temperature and emission characteristics of dimethyl ether (DME) fuel compared with ultra-low sulfur diesel (ULSD) fuel through experimental and numerical analyzes. In order to analyze...

In the present study, the combustion and emission characteristics under various equivalence ratio up to stoichiometric condition were experimentally investigated in a CI (compression ignition) engine. In order to control the equivalence ratio, the O2 mole fraction of intake gas was reduced from...

Fuel crisis because of dramatic increase in vehicular population and environmental concerns have renewed interest of scientific community to look for alternative fuels of bio-origin such as vegetable oils. Vegetable oils can be produced from forests, vegetable oil crops, and oil bearing biomass...

Biodiesel is an alternative fuel consisting of the alkyl esters of fatty acids from vegetable oils or animal fats. Vegetable oils are produced from numerous oil seed crops (edible and non-edible), e.g., rapeseed oil, linseed oil, rice bran oil, soybean oil, etc. Research has shown that...

This study is to investigate the emission reduction characteristics of bioethanol blended diesel fuel at early injection condition including spray, atomization and evaporation characteristics. The spray atomization and evaporation characteristics were investigated using spray visualization...

This study was conducted to investigate the injection and atomization characteristics of biodiesel–ethanol blended fuel. The injection performance of biodiesel–ethanol blended fuel was analyzed from the injection rate characteristics using the injection rate measuring system, and the...

In engine combustion studies of bioethanol blended diesel fuels, biodiesel is a very important blending fuel for preventing phase separation between diesel and bioethanol. The purpose of this study is to investigate the impact of biodiesel in bioethanol blended diesel fuel on ignition delay,...
