Design And Dynamic Analysis Of Kinetic Energy Recovery System For Toyota Hilux 4x4

Abstract

In The Present Scenario, Energy Crisis Is One Of The Major Challenges To The Existing World. The Fossil-Fuel Resources Are Being Depleted At A Tremendous Rate Due To Their Disproportionate Consumption. This Has Put Forth The Widespread Assumption That If Resources Are Being Used At Current Rate, The Time Is No Longer When All Our Resources Will Expire. Thus, There Is A Need To Develop The Technology That Saves The Energy From Getting Wasted. Traditionally, Regenerative Braking With The Ability To Generate Energy Has Been Promising But The Amount Of Energy Saved Is Highly Insignificant. A Considerable Amount Of Energy, Which Is Generated By The Engine, Is Lost While Braking Even In Case Of Regenerative Braking. The Regenerative Braking Involves Direct Conversion Of The Kinetic Energy To Electrical Energy; However, A Promising Alternative Is Present While Storing The Kinetic Energy Of The Vehicle In The Form Of Mechanical Energy Of A Rotating Cylindrical Flywheel. This Thesis States The Advantages Of Storing The Kinetic Energy Of The Vehicle In Mechanical Form Rather Than Direct Conversion For The Design Of This Kinetic Energy Storing Device Some Calculation Are Done For The Vehicle At Different Resistance Load, Torque, Speed And Calculation For Selection Of The Planetary Gear, Design Of Flat Spiral Spring Are Considered And Also Using Solid Work Software Some Parts Of The System Are Designed. By Taking The Velocity Of The Vehicle From 8.34m/Sec To 27.8 The Kinetic Energy Loss Of The Vehicle Is Increasing With The Increase Of Velocity But Efficiency Of The Kinetic Energy Recovery System Will Decrease. Braking The Vehicle With Velocity Of 8.34m/Sec Has 219kj Of Kinetic Energy Loss And Energy Stored By Flat Spiral Spring Is 201.4kj And The System Is 91.9% And Can Save 0.00464l Of Fuel From 0.005l Which Will Be Consumed At 8.34m/Sec. But Vehicle Moving At 27.8m/Sec The Kinetic Energy Loss Is 2434.4kj And The Stored Energy Is 201.4kj And The Kinetic Energy Recovery System Is 8.3%. So Using Of Flat Spiral Spring Kinetic Energy Recovery Is Effective And Recommendable For Vehicle Which Has High Stop And Go Times.
