CPT VTES Electric Supercharger Selected for Two Projects

Green Car Congress

When applied to a radically downsized 1.2-liter liter turbocharged engine, VTES delivers in excess of a 50% increase in torque at engine speeds below 3,000rpm, more than compensating for insufficient power from the exhaust turbine. More than 90% of the available torque is delivered in less than a second. Compared with a 1.6-liter

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.,

NRC report finds significant number of near-term technologies could greatly reduce fuel consumption in passenger cars

Green Car Congress

Further, the benefits of some technologies are not completely represented in the tests used to estimate corporate average fuel economy (CAFE). Turbocharging and downsizing can also yield fuel consumption reductions. NHTSA also asked that the NRC add to its assessment technologies that have emerged since that report was prepared.
