Automobile Technology by Dr N K Giri
During the last several years, there has been a tremendous increase in the interest and attention given to the study of automobile technology. This trend has been fueled by the growing number of cars on the road. Moreover, the advent of automobile technology has enabled the advancement of technologies that improve the efficiency of vehicle operations. These include the introduction of electrical and electronic systems.
Introduction to electrical and electronic systems used in automobiles
Throughout the years, the electronics used in cars have become more complex. In fact, the automotive industry is estimated to have about a third of its total cost in electronics. Automotive electronics include in-car infotainment systems, radios, telematics, and in-engine electronics. Automotive electronics are gaining popularity as they improve safety, fuel efficiency, and driver comfort.
Automotive electrical systems are used to power all electrical devices in a vehicle. When the engine is running, the alternator charges the battery. This power is then distributed to electrical devices. The alternator also regulates the amount of power that electrical devices receive. The alternator is designed to provide a higher output when the engine is running, and a lower output when the engine is not running.
The alternator is also used to charge the battery when the car is not running. The car’s battery is connected to the earth terminal by a thick cable.
In addition to charging the battery, the alternator is also used to provide electrical power to the electrical devices. In a modern car, the alternator is a 12 volt system. This voltage is lower when the engine is not running, so the current flowing through the battery is reduced.
Designed as a full course for undergraduate engineering students, this book provides a comprehensive treatment of modern automobile technology. Its contents include solved numerical examples, a large number of review questions, and examples taken from examination papers. It provides students with a better foundation for their future studies. The book is also accompanied by a CD-ROM containing several additional materials. It is ideal for students who want to prepare for a diploma in automobile engineering.
The book is divided into six general divisions. The first part is introductory material to help students understand the functioning of electrical and electronic systems. The second part contains a number of examples taken from various examination papers, a discussion of recent developments, and a number of review questions. The third part covers a number of concepts relating to thermodynamics, fuels, and engine design.
