2 Performance Analysis for Selection of Operational Parameters I.C. Engines P M V Subbarao Professor Mechanical Engineering Department Actions Recommended & Approved by Reactions….

3 Selection of Mixture Strength for Better Reaction -1 Air-standard Analysis Real Reaction Fuel-Air Analysis Rich Lean

4 Selection of Mixture Strength for Better Reaction -2 Air-standard Analysis Fuel-Air Analysis Real Reaction Rich Lean

5 Selection of Sufficient Air : Optimization of Total Cost 4

6 Combined Thermodynamic & Chemical Optimization for Better Reaction -2 r = 8 r = 10

7 Combined Thermodynamic & Kinetic Optimization for Better Reaction -2

8 Engine Capacity Vs Performance

9 Optimizing Engine Performance Engines are most efficient at or near peak load. Efficiency drops with a reduction in torque load. At zero brake torque, all fuel energy is expended in engine friction. Lower rated engine speeds provide lower BSFC, and at the same time reduce torque reserve – design compromise. Heavy engines for a given capacity….. More inertial losses… Compromise – Necessary Evil ….. Any alternate to overcome this fact….. Develop an idea to Change natural behaviour…..

10 Artificial Breathing Attachments to Engines Preferred Artificial Breathing ….
