Transportation is second only to industrial use as the largest consumer of energy in the US and accounts for about 60% of our nation’s use of petroleum—an amount equivalent to all of the oil the country imports. The numbers are staggering: Some 10 000 gallons of petroleum are burned in the US each second of every day. Although new energy sources are being developed and renewable fuels are emerg...

With latest improvements in MEMS, combustion based Micro-Power generation devices are seen as alternatives for conventional batteries because of the high energy densities of Hydrogen and other hydrocarbon fuels. An important feature of micro-power system is to utilize the combustion of fuel or propellant in the micro-burner to produce the gas with high temperature and high pressure to drive tur...

In the present work, a pebble bed thermal energy storage (PBTES) system is developed to utilize waste from engine exhaust. The PBTES integrated with an electric dynamometer coupled stationary Diesel for experimental investigation. performance compared and without integration of system. 60-75% can be stored in fabricated during charging process at various load conditions. It found that nearly 11...

A significant fraction of the energy released by magnetotail reconnection appears to go into ion heating, but this heating is generally anisotropic. We examine ARTEMIS dual-spacecraft observations of a long-duration magnetotail exhaust generated by antiparallel reconnection in conjunction with particle-in-cell simulations, showing spatial variations in the anisotropy across the outflow far (>10...

A sensor network is deployed to monitor and collect the information of environment. The common methods to organize sensors are the cluster and chain architecture. In the chain architecture, each sensor needs to report its gathered data and relay the data of its neighbours to the collector. The sensors which are close to the collector always exhaust their energy faster than the ones in the edge ...

This study investigates how high levels of exhaust gas recirculation (EGR) combined with certain fuel injection strategies and energy recovery systems affect diesel engine emissions and fuel economy. The key test apparatus was a John Deere 4.5L diesel engine which was modeled using the computer-based engine simulation tool GT-Power. The conclusion was made that utilization of high EGR levels (3...

Hybrid energy source is becoming general because it is composed from two or more energy sources. This combination of two or more energy sources is a competent way of generating energy. The amount of the conventional energy sources is reducing day by day. To avoid energy inaccessibility, the use of renewable energy sources is extremely essential. Hybrid operation raises the reliability of stand-...

here are six main classes of gaseous contaminants which are routinely described in Tautomotive exhaust (a term which will be used here to refer to both automobile and diesel exhaust). As shown in Table 1, carbon monoxide (CO) is the largest component of automobile exhaust whereas the oxides of nitrogen (NO ) constitute the main components of diesel exhaust. x Even though nitrogen oxides contrib...

OBJECTIVES Air pollution particulates have been identified as having adverse effects on respiratory health. The present study was undertaken to further clarify the effects of diesel exhaust on bronchoalveolar cells and soluble components in normal healthy subjects. The study was also designed to evaluate whether a ceramic particle trap at the end of the tail pipe, from an idling engine, would r...
