Characterization of Porous Graphite Air Bearings
Byron R. Knapp, Brian P. O’Connor, Eric R. Marsh Machine Dynamics Research Lab The Pennsylvania State University, University Park, PA Introduction As the demand for higher precision machine tools and inspection equipment grows, there is a need for more precise bearing systems. The error motions of bearings with mechanical contact are dominated by the geometric and surface finish errors of their...
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 کاملDriveline torque observer for heavy duty vehicle
In addition to fuel consumption and efficiency the expectations in driving comfort of heavy duty vehicles were substantially increased in the last years. The driveline has an essential role in drivability performance of the vehicle. Since it determines the driving efficiency as well, simple, but robust devices were quite widespread in production, but these can usually make driving more difficul...
متن کاملOn-board diagnostics for heavy-duty vehicles: Considerations for Mexico
On-board diagnostic (OBD) systems monitor the performance of engine and aftertreatment components including those responsible for controlling emissions.1 Historically, OBD systems were first deployed in light duty vehicles (LDVs), in 1991 the United States and 10 years later in Europe. Those first OBD systems were very basic and had very little standardization, meaning that each manufacturer ad...
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...
