This chapter discusses the concept of turbocharging the spark- ignition engine both within the historical context of increasing performance and in the modern one of its application for fuel consumption and CO2 reduction. The advantages and drawbacks of turbocharging are discussed against the use of external fuel delivery, and then the mechanisms by which in-cylinder direct fuel injection addresses most of the disadvantages are described. The chapter concludes with a section discussing some future trends and possibilities for the technology, including its synergy with some of the alternative fuels currently being proposed (principally the alcohols), with cooled exhaust gas recirculation EGR for knock suppression and also with some new engine architecture developments. © 2010 Woodhead Publishing Limited.
