ME 419 - Internal Combustion Engines

2 lecture hours 2 lab hours 3 credits
Course Description
This course covers the basic theory and design of internal combustion reciprocating engines. Course topics include mechanical design concepts, engine performance parameters, combustion, engine cycles, fuels, and emissions. (prereq: ME 3105 )
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
  • Understand the general engineering operation and design compromises involved in spark and compression ignition engines
  • Be familiar with common I.C. engine terminology such as knock, detonation, auto ignition, surface to volume ratio, and compression ratio
  • Apply thermodynamics to I.C. engine processes and cycles
  • Analyze the engine parameters of friction, torque, MEP, IHP, and bsfc
  • Understand the mechanisms of combustion and the effect of air-fuel ratio on performance
  • Understand the variables which influence the production of undesirable emissions
  • Understand the importance of air flow and how it is affected by valves and by forced induction (turbocharging and supercharging)
