“…For example, works by EPA [4] and Zoepf and Heywood [5] study the deployment of individual technologies. Kasseris [6] developed projections of future vehicle efficiency based on assumed values for road loads and efficiency parameters in various subsystemsmany of which were informed by their historic trends. One challenge when working with the bottom-up view is the potential interdependence of the rates of adoption of multiple technologies at the same time.…”

“…Transmissions are inevitable for internal combustion engines (ICE). They operate at speeds higher and torques lower than those requested at the vehicles wheels (Kasseris, 2006). Optimised gearboxes and dual clutches can improve fuel economy by 1e5% (Smokers et al, 2006).…”

a b s t r a c tEmissions from land transport, and from road transport in particular, have significant impacts on the atmosphere and on climate change. This assessment gives an overview of past, present and future emissions from land transport, of their impacts on the atmospheric composition and air quality, on human health and climate change and on options for mitigation.In the past vehicle exhaust emission control has successfully reduced emissions of nitrogen oxides, carbon monoxide, volatile organic compounds and particulate matter. This contributed to improved air quality and reduced health impacts in industrialised countries. In developing countries however, pollutant emissions have been growing strongly, adversely affecting many populations. In addition, ozone and particulate matter change the radiative balance and hence contribute to global warming on shorter time scales. Latest knowledge on the magnitude of land transport's impact on global warming is reviewed here.In the future, road transport's emissions of these pollutants are expected to stagnate and then decrease globally. This will then help to improve the air quality notably in developing countries. On the contrary, emissions of carbon dioxide and of halocarbons from mobile air conditioners have been globally increasing and are further expected to grow. Consequently, road transport's impact on climate is gaining in importance. The expected efficiency improvements of vehicles and the introduction of biofuels will not be sufficient to offset the expected strong growth in both, passenger and freight transportation. Technical measures could offer a significant reduction potential, but strong interventions would be needed as markets do not initiate the necessary changes. Further reductions would need a resolute expansion of low-carbon fuels, a tripling of vehicle fuel efficiency and a stagnation in absolute transport volumes. Land transport will remain a key sector in climate change mitigation during the next decades.

Turbocharging technology is today considered as a promising way for internal combustion engine energy saving and CO 2 reduction. Turbocharger design is a major challenge for turbocharged engine performance improvement. The turbocharger designer must draw upon the information of engine operation conditions, and an appropriate link between the engine requirements and design features must be carefully developed to generate the most suitable design recommendation. The objective of this research is to develop a turbocharger design approach for better turbocharger matching to an internal combustion engine. The development of the approach is based on the concept of turbocharger design and interaction links between engine cycle requirements and design parameter values. A turbocharger through flow model is then used to generate the design alternatives. This integrated method has been applied with success to a gasoline engine turbocharger assembly. turbocharger design, internal combustion engine, integrated method, through flow model Citation:Zhang Y J, Chen T, Zhuge W L, et al.
