The Drive for Low Emissions
On Road Vehicles: Aeristech & Engine Downsizing
Globally, Europe leads the way in reducing vehicle emissions (such as NOx, SOx and CO2) through increasingly tough tailpipe legislation. The current set of standards, Euro 5, was introduced in September 2009 for new models (January 2011 for all models). The newly-announced standards, Euro 6, are set to be introduced in September 2014 for new models, which entail notable reductions in emission levels for light-duty vehicles.
Vehicle manufacturers have made substantial improvements already in average fuel economy and are actively pursuing many additional initiatives: lightweight materials, alternative fuels, hybridization, battery electric and fuel cell vehicles. But conventional ICE vehicles will still play a major role in the world transportation for the foreseeable future. Manufacturers continually drive towards improving petrol and diesel engine efficiency (therefore reducing NOx, SOx and CO2 emissions) and many are following the current trend of engine downsizing, as one of the most practical strategies for the near term.
Furthermore, manufacturers face an additional challenge with the likely introduction of the World-harmonized Light-duty Vehicles Test Procedure (WLTP) in replacement of the current New European Driving Cycle (NEDC), often criticized for not being representative of real driving conditions. Driving cycles are an essential element for the measurement of fuel consumption and emissions.
Aeristech’s technology and range of electrically driven boosting solutions, Electric Superchargers (eSuperchargers) at 12V and 48V levels, and FullElectric Electric Turbocharger Technology (FETT) will enable further extreme engine downsizing. Aeristech has indeed solved a major problem by eliminating perceived turbo lag at an affordable cost. Through its range of electric boosting devices, Aeristech offers practical opportunities to downsize engines whilst improving vehicle performance, engine efficiency and driver satisfaction.
