A large US retailer that procures transportation services from third-party carriers experienced an unexpected jump in fuel surcharges as the price of diesel fuel skyrocketed in the summer of 2008. As a result, it sought to limit its future exposure to diesel price risk. We collaborated with this retailer to create a lane assignment optimizer (LAO) that incorporates diesel price risk when select...

Due to the shortage of liquid hydrocarbon fuels for compression ignition engines, researchers have constantly been looking for alternative fuels. Recently, dim ethyl ether (DME) with its interesting properties, such as high cetane number and low exhaust emission has drawn a lot of interst as a suitable fuel for diesel engines. The main objective of this study was to assess the potentials and fe...

The use of bio-ethanol as an alternative diesel engine fuel is increasing rapidly. Bioethanol is mixed with diesel fuel in different ratios and used in CI and SI engines. Vibrations have direct effects on engine components and users when the engine is operated on a vehicle. For this reason, analysis of vibration resulting from combustion in IC engines is very important. In this study, evaluatio...

The results of an experimental work carried out to evaluate the effect of palm oil methyl esters, also known as palm oil diesel (POD) and its emulsions as alternative fuel on unmodified indirect injection diesel engine's wear and lube oil performance are presented in this paper. Half throttle engine with constant 2500 rpm setting was maintained throughout the wear debris and lube oil analysis s...

Fuel cells have been recognized as a feasible alternative to current IC engines. A significant technical problem yet to be resolved is the on bound fuel supply before fuel cells can be practically used for vehicles. Use of an on-board fuel reformer can mitigate the fuel supply issue. In particular, using a diesel engine as on-board fuel reformer, combined with a fuel cell, is a strong candidate...

Due to diminishing petroleum reserves and the environmental negative effects of exhaust gases from diesel engines, alternative fuels for diesel engines are becoming increasingly important Egyptian waste cooking oils have special specifications because it expose to high temperatures during use for long hours. In the present experimental study, the performance and emissions of a four strokes, sin...

This study focuses on the physicochemical fuel characteristics and engine performance-emission features of three prospective alternative transportation fuels: Alexandrian laurel biodiesel (ALBD), jatropha biodiesel (JBD) and GTL fuel at high idling conditions. The blends of GTL fuel (G10, G20), JBD (J10, J20) and ALBD (AL10, AL20) with diesel had been investigated in a multi-cylinder diesel eng...

This investigation is an effort to find best optimization method for diesel engine using blended fuel. Present time, the scarcity of fossil fuel is a serious problem all over the world. So, researchers are trying to find best alternative fuel for that conventional fuel. When we use alternate fuel in diesel engine, we must have to optimize the parameter of diesel engine. The present trend will b...

The design and development of modern internal combustion engines is marked by a reduction in exhaust gas emissions and increase in specific power and torque. This paper aims at the study of noise reductuion in4-stroke common rail direct injection engine at idle speed. Idle speed is basically a speed of engine when vehicle is not running i.e not in motion . Now a days , this siuation oftenly com...

The objective of the work was investigation of possibility of dual fuelling of CI engine with diesel fuel and ethyl alcohol in order to decrease engine emission and increase its thermal efficiency. Alcohol, which is injected to the engine inlet port evaporates quickly, but doesn't ignite (due to low cetane number). After self-ignition of diesel fuel, ignited alcohol would promote further burnin...
