to eliminate turbo lag—in support of aggressive engine downsizing. CPT recommends a combination of the highly dynamic electric supercharger in series with a conventional exhaust-driven turbocharger to optimize the overall response of the system, compared to other air charging methods. Boost pressure is directly controlled by the ECU.

Globally, diesel engines will retain a significant share of global light vehicle sales at nearly 18 percent, due to their lower fuel consumption and carbon dioxide emissions. Regional highlights include: In North America, more engine downsizing is expected. The current average engine size is a 3.0-liter liter six-cylinder.

Having better control over the combustion process reduces the emission load on the exhaust aftertreatment systems. Eminox SCRT technology can significantly reduce harmful diesel exhaust gases, particularly in urban operating conditions. NO x emissions regulations are also likely to be further tightened. —Andy Dickinson.

the Worldwide harmonized Light vehicles Test Procedures (WLTP). This means that in addition the power demand is more difficult to achieve with engine downsizing and transmission down-speeding alone. The EU goal is to introduce the WLTP by 2017 if possible and no later than 2020 to coincide with the 95 g/km requirement. The conference.
