About Book:
We are pleased to bring out our first edition of “Automobile Engineering for Engineering and Technology studies. This book is written to serve the of undergraduate students embarking introductory course in Auchi Expiring This book is based on the latest syllabus prescribed by the Anna University, Che for Mechanical Engineering students of its affiliated colleges
The term automobile or automotive stands for a vehicle which can be by itself. Therefore, an automobile is a self-propelled vehicle, It is used for the transportation of passengers and goods from one place to another on the ground t made up of a frame supported by the body and power producing units and power units. These units are further supported by tyres and wheels which are connected by springs and axles. In general, the power is produced by internal combustion engines. This power inturn is transmitted to rear wheels through various transmission systems such as clutch, propeller shaft, gear box, differential units etc The various units are held together in a proper position and arranged on the frame The automobile is propelled through the friction between tyre and ground. The super structure or body of the automobile provides protection and comfort to the passenger
Modern automobiles are produced by using complex components of machineries and therefore, it requires careful attention for making it to perform tasks in a safe, economical and efficient way. Thus, for any mechanical engineer, it is essentially required to have the knowledge of various components and functions of automobiles.
This book consists of 5 units.
Unit 1 deals with Types of automobiles, Vehicle construction, Different layouts, Chassis, Frame and Body, Vehicle aerodynamics, Resistances to vehicle motion, Components, functions and materials of IC engines and Variable Valve Timing (VVT).
Unit 2 has an in depth dealing of Carburetors, Electronic Fuel Injection Systems for SI and diesel engines, Electronic ignition system, Turbochargers,Engine emission control by three way catalytic converter system and Emission
norms (Euro and (IS)
Unit 3 deals with Clusches, manual and automatic Gearboxes, grar shin mechanisms, Overdrives Propeller shaft, Transfer box, Fluid flywheel, Torque converter, Slip joints, Universal joints, Differential, Rear Axle in transmission systems, and Hotchkiss drive and Torque tube drive
Steering geometry, Types of steering gear box, Power Steering. Types of front Suspension systems, Pneumatic and Hydraulic braking systems. Anti Lock Braking System (ABS), Electronic brake force distribution (EBD) and Traction Control are elaborately discussed in Unit 4
Use of natural gas, Liquefied Petroleum Gas (LPG), Bio-diesel, flip-ethanol, Gaschol 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 and Fuel cells are treated elaborately with advanced vehicles running today in Unit 5.
Important solved Anna University questions, and Two mark questions and answers have been added at the tail end of each unit which will enable the students to score high marks in the University examinations. Solved Anna University Question Papers have been added at the end of this book
