The increased number of automobiles in recent years has resulted in great demand for fossil fuel. This has led to the development of automobile by using alternative fuels which include gaseous fuels, biofuels and vegetables oils as fuel. Energy from biomass and more specific bio-diesel is one of the opportunities that could cover the future demand of fossil fuel shortage. Biomass in the form of...

A comprehensive study on the methanol as an alternative fuel has been carried out. A four stroke four cylinder diesel engine was adopted to study engine power, torque, break specific fuel consumption, break thermal efficiency and exhaust temperature with the fuel of fraction methanol in diesel. In this study, the diesel engine was tested using methanol blended with diesel at certain mixing rati...

in this paper, optimal design of hybrid solar-wind- diesel energy system with battery storage for reliable load in arsoon village in ardabil is presented. the village has 35 households that mean daily energy consumption is estimated 63.4 kwh. in this design optimization is implemented, considering loss of power supply probability (lpsp) index for reliable load providing, with minimum total cons...

This paper presents an experimental investigation into the detection of excessive diesel knock using acoustic emission (AE) signals. Three different dual-fuel diesel engine operating regimes were induced into a compression-ignition (diesel) engine operating on both straight diesel fuel and two different mixtures of fumigated ethanol and diesel. The experimentally induced engine operating regime...

Diesel exhaust particles (DEP) contain elemental carbon, organic compounds including Polyaromatic hydrocarbons (PAHs), metals, and other trace compounds. Diesel exhaust is complex mixture of thousands of chemicals. Over forty air contaminants are recognized as toxicants, such as carcinogens. Most diesel exhaust particles have aerodynamic diameters falling within a range of 0.1 to 0.25 μm. DEP w...

Abstract The traction motor is the power source of locomotive. If surface waviness occurs on races bearing, it will cause abnormal vibration and noise, accelerate fatigue wear, seriously affect stability safety transmission. In this paper, an excitation model coupling time-varying displacement contact stiffness excitations adopted to investigate effect bearing under from locomotive-track couple...

The present work is focused on determining the performance and emission characteristics biodiesel in DI diesel engine. Experimental investigation of diesel engine was made with 25% (B25), 50% (B50) and 75% (B75) and 100%(B100) blending of Ziziphus jujuba oil with diesel and the results were compared with diesel. Keywords— Ziziphus jujuba, Indian jujube, Edible, Blending, direct injection (DI) d...
