The devices could increase the fuel economy of conventional vehicles by recapturing part of the waste heat from engine exhaust and generating electricity to power accessory loads. A simple vehicle and engine waste heat model showed that a Class 8 truck presents the least challenging requirements for TE system efficiency, mass, and cost; these trucks have a fairly high amount of exhaust waste heat, have low mass sensitivity, and travel many miles per year. These factors help maximize fuel savings and economic benefits. A driving\/duty cycle analysis shows strong sensitivity of waste heat, and thus TE system electrical output, to vehicle speed and driving cycle. With a typical alternator, a TE system could allow electrification of 8%-15% of a Class 8 truck's accessories for 2%-3% fuel savings. More research should reduce system cost and improve economics. \u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e National Renewable Energy Laboratory (Nr\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1249164923\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781249164920\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Bibliogov\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 07\/20\/2012\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 28\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.15lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.69h x 7.44w x 0.06d","brand":"National Renewable Energy Laboratory (Nr","offers":[{"title":"Paperback","offer_id":47611121860863,"sku":"9781249164920","price":15.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_916211c1-13de-4a98-8558-4e433d65c7f1.jpg?v=1764511868","url":"https:\/\/www.whiterainbookhouse.com\/products\/feasibility-of-thermoelectrics-for-waste-national-renewable-energy-laboratory-nr-9781249164920","provider":"WR Book House","version":"1.0","type":"link"}
