Comparison of life cycle greenhouse gases from natural gas pathways for medium and heavy-duty vehicles.
The low-cost and abundant supply of shale gas in the United States has increased the interest in using natural gas for transportation. We compare the life cycle greenhouse gas (GHG) emissions from different natural gas pathways for medium and heavy-duty vehicles (MHDVs). For Class 8 tractor-trailers and refuse trucks, none of the natural gas pathways provide emissions reductions per unit of fre...
متن کاملSelective Catalytic Reduction for Heavy-duty and Light-duty Vehicles
Whereas previous emission limit values could be met by primary engine control measures, the limits for PM and NOx from heavy duty engines in 2008/09 (Euro V) and diesel passenger cars in 2014/15 (Euro 6) represent a challenge for the developers of diesel engines and vehicles. Due to the thermodynamics of the Diesel combustion process, it is difficult to optimise the combustion process for both ...
متن کاملPlanning for Medical Emergency Transportation Vehicles during Natural Disasters
One of the main critical steps that should be taken during natural disasters is the assignment and distribution of resources among affected people. In such situations, this can save many lives. Determining the demands for critical items (i.e., the number of injured people) is very important. Accordingly, a number of casualties and injured people have to be known during a disaster. Obtaining an ...
متن کاملDecentralized Diagnosis in Heavy Duty Vehicles
Fault diagnosis is important for automotive vehicles, due to economic reasons, such as efficient repair and fault prevention, and legislative reasons, mainly safety and pollution. Embedded systems in vehicles includes a large number of electronic control units, that is connected to each other via an electronic network. Many of the current diagnostic systems use pre-compiled diagnostic tests, an...
متن کاملDesign and analysis of a thermoelectric generator for a heavy-duty vehicle in real road test
Heavy duty vehicles have a great share on fossil fuel consumption and greenhouse gases in the world, while they waste two third of chemical energy of fuel. On the other hand, simplicity and long life of thermoelectric generators (TEGs) are considered more and more to convert thermal energy to electrical one. In this paper a TEG designed in the exhaust system of Renault Midlum 195 Dxi Engine. Th...
