Concept: Downsized and Supercharged Hybrid Pneumatic Engine for 30%+ Reduction in Fuel Consumption

Green Car Congress

Schematic of downsized and supercharged four-stroke hybrid pneumatic spark injection engine. The reduction in fuel consumption is obtained mainly through enabling the effective use of a heavily downsized engine, rather than from regenerative efficiency. Source: ETH Zürich. Click to enlarge.

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. Unlike a turbocharger, Cobra is not dependent on the exhaust gases flowing to do its work.

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

Green Car Congress

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. —Andy Dickinson, the senior manager at CPT responsible for Cobra.

Mazdas new SKYACTIV gasoline and diesel engines are steps on the road to its Ideal Engine; focus on compression ratio

Green Car Congress

Since this energy loss is primarily thermal in nature and can be attributed to the exhaust, cooling system, and engine and transmission surfaces, Mazda’s R&D team’s central focus is on improving the engine’s thermal efficiency cost-effectively. Extreme compression ratio rather than downsizing. Although downsizing—i.e.,
