A wise man once said, "Passion is the source of our finest moments." How
true! Think about your life. Aren't your greatest memories filled with
passionate feelings? It could have been joy, love, pride, or even sadness, but
the one thing in common with all of these emotions is passion.
Passion intensifies your total experience of any moment and inspires you to
bring your dreams to life. It prevents you from filling your existence with
lackluster episodes of boredom.

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.
A typical 4 cylinder vehicle cruising along the highway at around 50 miles per hour, will produce 4000 controlled explosions per minute inside the engine as the spark plugs ignite the fuel in each cylinder to propel the vehicle down the road.
Engine management systems are designed to ensure that the vehicle complies with emissions regulations as well as to provide improved performance. This means that the number of sensors and actuators is considerably greater than for a simple fuelling or ignition system.
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.
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
Sputtering is similar to vacuum deposition. In this method, an inert gas such as argon or helium is introduced into a chamber that contains anode and cathode electrodes supplied by an external high-voltage source. The anode contains the sample to be deposited on and the cathode contains the deposited material. The principle is that the high voltage ignites a plasma effect in the inert gas and the gas ions bombard the target containing the material to be deposited. When the kinetic energy of the bombarding ions is sufﬁciently high, some of the atoms from the target surface are freed and...
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....

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. ...
