Eddy posits that rising fuel costs will push technologies that allow more power to be produced by smaller engines, including a resurgence turbocharging. Widely used in Europe with diesel engines, Eddy says turbocharging will reappear in North American gasoline engines as part of 2010 introductions. Some the turbochargers will use external air coolers, which could create opportunities high-heat-resistant elastomers for conditions above 170°C.
