UNIT II	VEHICLE FRAMES AND STEERING SYSTEM	9

Vehicle construction and different Chassis layouts – classifications of chassis - types of frames - frameless chassis construction –articulated vehicles - vehicle body - Vehicle aerodynamics - various resistances and its effects - steering system –conventional – sophisticated vehicle - and types of steering gear box - Power Steering - Steering geometry - condition for true rolling motion‐Ackermann’s - Devi’s steering system - types of stub axle – Types of rear axles.

UNIT III	TRANSMISSION SYSTEMS	9

Clutch - types and construction, gear boxes - manual and automatic, gear shift mechanisms, Over drive, transfer box, fluid flywheel, torque converter, propeller shaft, slip joints, universal joints – Hotchkiss Drive and Torque Tube Drive - rear axle - Differential - wheels and tyres.

UNIT IV	SUSPENSION AND BRAKES SYSTEMS	9

Suspension Systems - conventional Suspension Systems - independent Suspension Systems –leaf spring – coil spring –taper - lite - eligo,s spring Types of brakes - Pneumatic and Hydraulic Braking Systems, Antilock Braking System (ABS), electronic brake force distribution (EBD) and Traction Control. Derive the equation of Forces acting while applying a brakes on plain surface - inclined road - gradient.

UNIT V	ALTERNATIVE ENERGY SOURCES	9

Use of Natural Gas, Liquefied Petroleum Gas, Bio - diesel, Bio - ethanol, Gasohol and Hydrogen in Automobiles - Engine modifications required – Performance, Combustion and Emission Characteristics of SI and CI engines with these alternate fuels - Electric and Hybrid Vehicles, Fuel Cell. Turbo chargers - Engine emission control by three way catalytic converter system.
Note: Practical Training in dismantling and assembling of Engine parts and Transmission Systems should be given to the students.

TOTAL: 45 PERIODS

OUTCOMES:
