This course introduces students to the existing and future designs and principles involved in designing IC gasoline and diesel engines with emphasis on reciprocating engines. Basic engine operating and design characteristics and parameters are defined. Studies of p-V graphs develop understanding of theoretical and real engine cycles and their role in the development of an engine. Importance is placed on socioeconomic and regulatory demands to lower emissions and increase engine operating efficiencies. Influence of specific internal combustion system including injection types supercharging HCCI DoD/AFM/MDS/VCM VCT/VVT and VCR; ignition valve and cam timing and phasing; design of the combustion chamber; creation and utilization air/fuel mixture including both homogeneous or stratified charges on engine emissions efficiency and performance are explained. The use of sensors ECU and engine maps to deliver desired engine control strategies are introduced. Students develop understanding of petroleum-based and synthetic lubricants and liquid fuels gaseous fuels biofuels fuel additives and electricity in terms of their structures and as viable options for energy conversion within an ICE hybrid electric and fuel cell powertrains. Included are discussions of pros and cons of each fuel application and their influence on emissions and efficiencies and socioeconomic considerations. Advanced topics include power transfer from combustion chamber to crankshaft; engine forces and balancing; engine loads affecting component sizing; and loads for design of journal bearings. Visual inspections reinforce student ability to identify engine subsystems and components describe their functions discuss their design features and identify manufacturing technologies utilized. Students prepare and deliver engine design presentations involving heat engine history fuels energy conversion and storage systems hybrid and electric powertrains fuel cells engine motosport applications engine curiosities and combustion systems. The emphasis is on passenger car and light trucks However other prime mover applications will be introduced time permitting and where appropriate.
