A jet engine‚ like a rocket engine‚ is a reaction engine. It works by throwing mass in one direction and taking advantage of the reaction in the opposite direction. In the case of a jet engine‚ the engine burns fuel (like kerosene) with air from the atmosphere. The burning fuel heats and expands the air‚ and this hot air shoots out of the exhaust-end of the engine to create thrust. Most modern jet engines use a turbine to improve the efficiency of the engine and allow the engine to work at low speeds

dominate the personal computer market‚ AMD has for years been its most serious rival. As far back as the launch of the original IBM PC in 1981‚ AMD was a second-source supplier of microprocessors using Intel’s x86 design. But the companies spent much of the next 15 years sparring over AMD’s right to market chips using Intel’s technology. A 1995 settlement gave AMD the right to use the designs for Intel’s x86 processors. Intel is the best processor to buy and the most power packed processor launched. Intel

555 timer ic The 555 Timer IC is an integrated circuit (chip) implementing a variety of timer and multivibrator applications. The IC was designed by Hans R. Camenzind in 1970 and brought to market in 1971 by Signetics (later acquired by Philips). The original name was the SE555 (metal can)/NE555 (plastic DIP) and the part was described as "The IC Time Machine".[1] It has been claimed that the 555 gets its name from the three 5 eke resistors used in typical early implementations

Green Engine seminar report.DOC (Size: 107 KB / Downloads: 3197) ABSTRACT The green engine is one of the most interesting discoveries of the new millennium. It has got some unique features that were used for the first time in the making of engines. This engine is a piston less one with features like sequential variable compression ratio‚ direct air intake‚ direct fuel injection‚ multi-fuel usage etc. The efficiency of this engine is high when compared to the contemporary engines and also the exhaust

Engine Problems while in Operation DIESEL ENGINE PROBLEMS: FUEL‚ AIR‚ STARTING‚ WIRING Many cases of engine failure are a result of a relatively small number of faults so it’s often possible to get the motor running again within a few minutes. However‚ when diagnosing problems it’s important to work in a systematic fashion and avoid the temptation to jump to conclusions.
