The automotive turbocharging industry will generate $12 billion in revenue by equipping 49 million vehicles with turbochargers annually by 2019, according to Honeywell Turbo Technologies’ 2014 Global Turbo Forecast. In addition to improving fuel efficiency, downsized turbocharged engines also reduce harmful exhaust emissions.

© 2019 Eshan Singh. —Singh and Dibble (2019). It is more prevalent in the downsized, turbocharged engines that car makers are now producing for improved fuel efficiency while maintaining power output. Pre-ignition remains a bottleneck to further downsizing and improving engine efficiency. and Dibble, R.

Thrust 1 builds on the significant amount of work carried out over the past several decades, focused on building advanced boosted, downsized, and downspeeded spark ignition engines. High combustion noise and high HC and CO emissions are also a problem, with lower exhaust temperatures representing a challenge for current emissions controls.
