  • This book on internal combustion engines brings out few chapters on the research activities through the wide range of current engine issues. The first section groups combustion-related papers including all research areas from fuel delivery to exhaust emission phenomena. The second one deals with various problems on engine design, modeling, manufacturing, control and testing. Such structure should improve legibility of the book and helps to integrate all singular chapters as a logical whole.

  • Internal combustion engines (ICE) are the main sources of powering for almost all road vehicles, yet many other machines too. Being under strength development for a number of years, they have already reached a relatively high level of technical excellence and now they also produce acceptable output parameters. Still, they are not devoid of drawbacks. Harmful exhaust emissions can be pointed as the most important here. This problem is the main focus of interest for automotive researchers and engineers.

  • Technological improvements might also involve the adoption and use of alternative fuel or alternative propulsion vehicles. In developing countries, the most commonly discussed alternative vehicle strategies include compressed natural gas (CNG), liquefied petroleum gas (LPG), alcohol-based fuels, and electric propulsion or hybrid -electric vehicles in certain applications. Other alternative fuels showing potential long -term promise in the transport sector include hydrogen fuel cells and various synthetic fuels for use in compression-ignition engines.

  • A control system is a collection of components working together under the direction of some machine intelligence. In most cases, electronic circuits provide the intelligence, and electromechanical components such as sensors and motors provide the interface to the physical world. A good example is the modern automobile. Various sensors supply the on-board computer with information about the engine’s condition. The computer then calculates the precise amount of fuel to be injected into the engine and adjusts the ignition timing. T...

  • semiconductors.In the first category are substances which provide an easy path for an electric current. All metals are conductors, however some metals do not conduct well. Manganin, for example, is a poor conductor. Copper is a good conductor, therefore it is widely used for cables. A non-metal which conducts well is carbon. Salt water is an example of a liquid conductor. A material which does not easily release electrons is called an insulator. Rubber, nylon, porcelain and air are all insulator. There are no perfect insulators.

  • To get around this restriction, many diesels incorporate an air pump in the form of an exhaust-driven turbocharger or a mechanical supercharger. Forced induction can double power outputs without violating the smoke limit. And, as far as turbochargers are concerned, the supercharge effect is free. That is, the energy that drives the turbo would otherwise be wasted out the exhaust pipe as heat and exhaust-gas velocity. The absence of an air restriction and an ignition system that operates as a function of engine architecture can wrest control of the engine from the operator.

  • 57.1.5 Gas Turbine Operation Like other internal combustion engines, the gas turbine requires an outside source of starting power. This is provided by an electrical motor or diesel engine connected through a gear box to the shaft of the gas turbine (the high-pressure shaft in a multishaft configuration). Other devices can be used, including the generator of large electric utility gas turbines, by using a variable frequency power supply.

  • Fuel Injection is a key process characterising the combustion development within Spark- Ignition (SI) and Compression Ignition (CI) Internal Combustion Engines (ICEs). Fuel Injection and Spray Behaviour in fact largely control the fuel-air mixing, combustion process efficiency, stability, the production of noxious species, the radiated noise, etc.The proper design of the fuel injection system requires the employment of both experimental and numerical techniques, sometimes coupled for optimisation procedures....

  • Wireless networks are being integrated into the modern automobile. The security and privacy implications of such in-car networks, however, have are not well under- stood as their transmissions propagate beyond the con- nes of a car's body. To understand the risks associated with these wireless systems, this paper presents a privacy and security evaluation of wireless Tire Pressure Moni- toring Systems using both laboratory experiments with isolated tire pressure sensor modules and experiments with a complete vehicle system.

  • Today’s direct-injection diesel engines are more rugged, powerful, durable, and reliable than gasoline engines, and use fuel much more efficiently, as well. engines start the explosions with sparks from spark plugs, whereas in diesel engines, fuel ignites on its own. Air heats up when it’s compressed. This fact led German engineer Rudolf Diesel to theorize that fuel could be made to ignite spontaneously if the air inside an engine’s cylinders became hot enough through compression.

  • History At the beginning of the automotive century, around 1900– 1910, battery electric vehicles (BEVs), cars with steam engines, and cars with gasoline engines coexisted. They were competing with respect to power, comfort, and maintenance. As described by R. H. Schallenberg, it took the electric starter and the starting, lighting, and ignition (SLI) system (created by Charles Kettering on the demand from Henry Leyland for the 1911 Cadillac Model Thirty) to improve the comfort in use of the gasoline engine vehicle sufficiently to outperform others. ...
