  4. Fp F Side φ F Rod Power TransmissionFBD Of Piston

  5. F Gas F Side F Rod r Fp F Side Torque Developed From Rod Loading On Crankshaft

  6. How Do We Evaluate Cylinder Pressure To Obtain Power? • Thermodynamics Portion Of The Analysis • Need To Make Some Basic Simplifying Assumptions: • Consider The Cylinder The Control Volume • First Pass Assume No Heat Transfer • Adiabatic – No Heat Transfer • Reversible Process - Isentropic • Simple Valve Operation

  7. Thermodynamic Analysis • Assuming A Closed Adiabatic System: • Ideal Gas Behavior • Simple Valve Operation

  8. 2 3 Cylinder Pressure 1 4 6 5 Cylinder Volume Engine ThermodynamicsWhat’s Happening In The Cylinder? 1 Intake Opens 2 Top Dead Center 3 Intake Closes 3-4 Adiabatic Expansion 4 Exhaust Opens 5 Bottom Dead Center 6 Exhaust Closes

  9. Next Steps • Utilize The Kinematics and Thermodynamics To Complete Simulation Provided On Web Site • Simulation Will Evaluate: • Output Torque • Component Loading • Cylinder Pressures and Temperatures • Utilize Component Loading In Stress Analysis Of Various Parts

  10. Assemblies / Family Tree’s • Assemblies And Sub Assemblies Should Reflect The Assembly Process • The Lower Level Parts Should Reflect The Assembly They Are Used On • The Family Tree Is A Graphical Representation Of The Parts Used In The Assembly And How They Are Assembled

  11. Family Tree
