"As we enter the 21st century, it is more vital than ever to take action to energy and environmental issues on worldwide perspective. The major challenge facing the 21st century is the crisis of global warming, and energy problems are themselves environmental problems. Fuel cells are actively being researched for use as distributed power units and vehicular power sources. As a result of their high efficiency and friendliness to the environment, the early adoption of fuel cells as new energy resource in practical applications is predictable. Conversely, in response to changes in the automotive market, development of technologies for conventional vehicles with gasoline and diesel engines that consume fossil fuels has also become vigorous. These include ways to increase fuel economy, reduce weight and purify exhaust gases, as well as to promote greater electrification and control-by-wire utilization. This book Light And Heavy Vehicle Technology deals with the theory and real world cases of vehicle maintenance, system, and analysis of vehicle problem, together with technological advances likely four-wheel drive, four-wheel steering, and anti-lock brakes. It covers the latest research and innovation on every aspect of passenger car and heavy vehicle engineering on the one hand, and engine development and technology on the other aspect. This work is also aimed towards studying, compiling, and analyzing the risks of the current ambient technology that is present in modern day cars. The development of sophisticated technologies inside cars make them an even more comfortable and compelling place to be in especially during transform to work, but recent security threats and entertainment have been uncovered with the upsurge usage of new technologies. Eminent authors from science and industry report on specific research projects as well as on the latest developments in vehicles, their engines and other components. Portraying special approach into development in automotive engineering and engine technology, this book will be of essential source of information for a worldwide audience of automotive engineers, practitioners and researchers as well."
