Comparison of diesel and hybrid vehicle emissions by computer modeling

摘要

Regional passenger transport is a rapidly growing market in Europe, as a result of the need to minimise pollution in cities by reducing the demand for personal transport. Persistent requirements for mass transport include: · Reduction in investment cost; · Minimisation of emissions; · Reduction of maintenance costs; · Improvements in energy efficiency. As the cost of electrification is often unacceptably high, diesel-powered vehicles are still the only remaining alternative. However, the maintenance costs associated with the diesel engine are very high, while frequent stop/start cycling on suburban routes results in high levels of noxious emissions and reduced energy efficiency. This paper describes a hybrid power train simulation model, in which an electric vehicle's operational performance has been set up to generate input data to a hybrid and a diesel vehicle model. Those models behave as independent vehicles predicting fuel consumption and emissions to be compared to each other running in identical traffic conditions.
