EIA: trends in downsized engine design leading to increased demand for higher-octane gasoline

Green Car Congress

One significant trend is engine downsizing coupled with turbocharging. Smaller, turbocharged engines can be used to raise fuel economy while meeting or exceeding the power and torque of larger engines, allowing engine downsizing and improved fuel economy with little or no performance compromise. In MY 2010, 12.5%

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

The main conclusions of the report include: Compared to emission controls on MY 2010 US diesel trucks, today’s compact aftertreatment systems are 40% lighter, 60% smaller, and substantially less expensive. This has resulted in higher catalyst loading per volume of substrate and led to downsizing of systems from those available in 2010.
