New lightweight aluminum piston from Federal-Mogul enables further downsizing of gasoline engines

Green Car Congress

The Advanced Elastoval II piston enters series production later this year in a new European passenger car, where it contributes to gains in fuel economy and reductions in CO 2. Specific power outputs in engines are likely to increase from current levels of around 95 kW/L to 130 kW/L to coming years. generation pistons.

CPT launching water-cooled electric supercharger for commercial diesel engines

Green Car Congress

Cobra could enable a 5–10% reduction in CO 2 emissions when implemented in conjunction with engine downsizing and down speeding strategies, and potentially more when used in conjunction with alternative fuels, according to CPT. The benefits of Cobra to the engine developer and end user depend on the application.

CPT and Eminox to collaborate on development of retrofit electric supercharging and aftertreatment solutions for heavy-duty vehicles

Green Car Congress

Essentially, the use of the Cobra supercharger helps reduce engine-out emissions, effectively making Eminox’s task easier. Having better control over the combustion process reduces the emission load on the exhaust aftertreatment systems. NO x emissions regulations are also likely to be further tightened. —Andy Dickinson.
