Vehicle Emission is one of the main causes of environmental damage. Vehicle engines produce carbon dioxide (CO2), hydrocarbon (HC), Nitrogen oxides (NOx) and many other harmful substances. An investigation was conducted using a compression-ignition engine fuelled with different ratios of blends of diesel and biodiesel at different EGR rates. The effects of different ratios of fuel blends and EG...

Homogenous Charge Compression Ignition (HCCI) is a mode of combustion in IC engines in which premixed fuel and air are ignited spontaneously. There is a belief that HCCI engines have a great potential to improve fuel consumption and reduce NOx emissions. In this study, a single zone, zero dimensional, thermo-kinetic model has been developed and a computer program with MATLAB software is use...

Diesel engine combustion becomes very rough and can lead even to deflagration under high altitude conditions, which is harmful component durability. In this study, the effects of on main characteristics—in-cylinder fluid flow, spray behavior, pressure temperature distribution—were analyzed with CFD. A numerical model was built CONVERGE platform validated optical behavior trace measured by test ...

Abstract Biomass may ignite due to biological oxidation and chemical oxidation. If this phenomenon (spontaneous ignition) is controlled, it would be possible produce biochar at a lower cost without the need for an external heat resource. We investigated if self-heating could controlled by using sawdust bark chips. When chips were used under conditions, temperature increased torrefaction tempera...

Biogas derived from organic wastes is considered as good alternative to petroleum fuels. It can be used in compression ignition (CI) engines, because of its better mixing ability with air and clean burning nature. Biogas is produced by anaerobic digestion of various organic substances such as kitchen wastes, agricultural wastes, municipal solid wastes, cow dung etc., in absence of oxygen, which...

various combustion characteristics and properties are studied while selecting a fuel for any engine. the choice of the engine and fuel are highly interrelated. vegetable oil is one obvious fuel particularly because their fuel properties are closer to diesel fuel. two important properties, the cetane number and the calorific value are similar to diesel. hence diesel engines can be operated on ve...
