A tailored model for the assessment of environmental benefits achievable by light-weighting design solutions in the automotive field is presented. The model is based on the Fuel Reduction Value (FRV) coefficient which expresses the Fuel Consumption (FC) saving involved by a 100 kg vehicle mass reduction. The work is composed by two main sections: simulation and environmental modelling. Simulati...

Around the world there is an increasing tend to introduce regulations concerning the environmental impact of products. In the automotive industry legislation has concentrated on exhaust emissions. Initially on-highway applications were regulated, but now attention has spread to include off-highway vehicles. This paper examines the impact of legislation on diesel engine manufacturers. They have ...

The history of ethanol-petrol blend application is summariserd. Past and future changes in the design of automotive engines are outlined. The properties of ethanol and petrol and their blends are compared. Early and recent reports on the performance of ethanol blends are summarised. The oil crisis coupled with the fact that likely contenders to replace present engines will operate efficiently o...

Two different samples of diesel exhaust particles (DEP) have been used by toxicologists interested primarily in cancer/genotoxicity or noncancer--such as pulmonary inflammation and asthma exacerbation--health end points. These are, respectively, a standard reference material, SRM 2975, from a heavy-duty diesel engine, and a sample collected by researchers at the Japanese National Institute for ...

Diesel plasmatron reformer technology can provide substantial throughputs without the need of using a catalyst The use of the special plasma facilitates robust noncatalytic conversion of diesel fuel into hydrogen rich gas with hydrogen yields that could be sufficient for NOx trap regeneration applications. Higher yields can be obtained with the use of a catalyst. Plasmatron reformers could also...

The primary objective of this study was to investigate and validate a predictive, turbulence based primary breakup model. The ESE model is based on a modeled evolution of the turbulent energy spectrum, and is sufficiently general that it may be applied to a broad range of pressure-atomized spray processes, such as those found in agricultural irrigation, industrial coating, automotive fuel injec...

OBJECTIVES To evaluate the efficiency of different automotive cabin air filters to prevent penetration of components of diesel exhaust and thereby reduce biomedical effects in human subjects. Filtered air and unfiltered diluted diesel exhaust (DDE) were used as negative and positive controls, respectively, and were compared with exposure to DDE filtered with four different filter systems. MET...

A linear (1 × 36) colorimetric sensor array has been integrated with a pre-oxidation technique for detection and identification of a variety of fuels and post-combustion residues. The pre-oxidation method permits the conversion of fuel vapor into more detectable species and therefore greatly enhances the sensitivity of the sensor array. The pre-oxidation technique used a packed tube of chromic ...
