Engine Capacity Vs Performance
![Page 8: Performance Analysis for Selection of Operational Parameters I.C. Engines P M V Subbarao Professor Mechanical Engineering Department Actions Recommended.](https://reader035.fdocuments.us/reader035/viewer/2022070416/5697c01f1a28abf838cd1e29/html5/thumbnails/8.jpg)
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…..
