CAAD (B-TECH automobile engineering 6th)

Introduction: Study and selection of vehicle specifications - Choice of Cycle, fuel, speed,

cylinder arrangement, number of cylinders, method of cooling, material, design variables and

operating variables affecting performance and emission.

Bearing, Belts and Chains systems: Design of sliding and rolling type of bearings, Details

of design of bearing housings, Design for the selection of V-belt, toothed belt and chains,

Design of pulley for belt, sprocket for chain.

Engine Design: Design of Engine Components, Cylinder and Cylinder Liner, Piston, Piston

Head or Crown, Piston Rings, Piston Skirt, Piston Pin, Connecting Rod, Crankshaft, Bearing

Pressure and Stresses in Crankshafts, Design for Centre Crankshaft, Valve Gear Mechanism,

Valves, Rocker Arm.

Axle and Steering system: Study of loads, moments & stresses in different sections of front

axle, king pin bearing and wheel spindle bearing, optimizing sizes of steering linkages, final

drive design considerations in different types of propeller shafts, final drive & rear axle.

Resistance to Vehicle Motion: Calculation and plotting the curves of air, rolling and

gradient resistances, driving force – Engine power, speed, rear axle ratio, Torque and

mechanical efficiency at different vehicle speeds.

Performance Curves: Resistance, Power and torque curve, Driving force against vehicle

speed – Acceleration and grad-ability in different gears for a typical car or truck plotted from

specifications.

Gear Ratios: Determination of Gear Ratios, Acceleration and grad-ability - typical problems.
