Book Description
Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles evaluates various technologies and methods that could improve the fuel economy of medium- and heavy-duty vehicles, such as tractor-trailers, transit buses, and work trucks. The book also recommends approaches that federal agencies could use to regulate these vehicles' fuel consumption. Currently there are no fuel consumption standards for such vehicles, which account for about 26 percent of the transportation fuel used in the U.S. The miles-per-gallon measure used to regulate the fuel economy of passenger cars. is not appropriate for medium- and heavy-duty vehicles, which are designed above all to carry loads efficiently. Instead, any regulation of medium- and heavy-duty vehicles should use a metric that reflects the efficiency with which a vehicle moves goods or passengers, such as gallons per ton-mile, a unit that reflects the amount of fuel a vehicle would use to carry a ton of goods one mile. This is called load-specific fuel consumption (LSFC). The book estimates the improvements that various technologies could achieve over the next decade in seven vehicle types. For example, using advanced diesel engines in tractor-trailers could lower their fuel consumption by up to 20 percent by 2020, and improved aerodynamics could yield an 11 percent reduction. Hybrid powertrains could lower the fuel consumption of vehicles that stop frequently, such as garbage trucks and transit buses, by as much 35 percent in the same time frame.

Book Description
14th International Conference on Turbochargers and Turbocharging addresses current and novel turbocharging system choices and components with a renewed emphasis to address the challenges posed by emission regulations and market trends. The contributions focus on the development of air management solutions and waste heat recovery ideas to support thermal propulsion systems leading to high thermal efficiency and low exhaust emissions. These can be in the form of internal combustion engines or other propulsion technologies (eg. Fuel cell) in both direct drive and hybridised configuration. 14th International Conference on Turbochargers and Turbocharging also provides a particular focus on turbochargers, superchargers, waste heat recovery turbines and related air managements components in both electrical and mechanical forms.

Book Description
The Institution’s International Conference on Turbochargers and Turbocharging (Twickenham, London, UK, 16-17 May 2023) returns to address the latest advances, research and developments in turbocharging system designs and boosting solutions. This volume presents a peer-reviewed collection of papers which will address current and novel turbocharging system choices and components with a renewed emphasis to address the challenges posed by emission regulations and market trends. The latest developments leading to enhanced performance and efficiency, increased durability and reduced emissions in line with meeting Net-Zero and global emissions targets. Topics include: Air management in powertrains: conventional, hybrids, fuel cells and novel configurations Alternate fuels and their needs in boosting (e.g. hydrogen, synthetic fuels) Electrification of turbochargers, compressors, and exhaust turbines Simulation and testing techniques, data analytics, including AI and digital twins Thermal management, waste heat recovery and expanders Turbomachinery aerodynamic: novel compressors & turbines and multi-stage systems. Component fatigue life, bearing design, rotor-dynamics and durability prediction Mechatronics, control, sensors and power electronics High speed turbomachinery in propulsion and power systems Future Legislation needs for thermal propulsion systems
