    Turbochargers

    more efficient than supercharging. New techniques such as twin-turbo/biturbo (whether parallel or sequential) setups and twin-scroll turbocharger, in combination with technologies such as variable valve timing and direct fuel injection, have cut down on turbo lag. • A turbocharger is basically an air pump. Hot exhaust gases leaving the engine after combustion are routed directly to the turbine wheel side of the turbocharger to make it rotate. That turbine wheel is connected by a shaft to a compressor wheel. • Some systems also include a tip turbine fan which draws air across the charge-air cooler to further reduce the temperature of the compressed air generated by the turbocharger. • A turbocharger, or colloquially turbo, is a turbine-driven forced induction device that increases an internal combustion engine's efficiency and power output by forcing extra air into the combustion chamber.[ This improvement over a naturally aspirated engine's power output is due to the fact that the compressor can force more air—and proportionately more fuel—into the combustion chamber than atmospheric pressure (and for that matter, ram air intakes) alone.  Turbocharger VS Supercharger • In contrast to turbochargers, superchargers are mechanically driven by the engine. Belts, chains, shafts, and gears are common methods of powering a supercharger, placing a mechanical load on the engine. For example, on the single-stage single-speed supercharged Rolls-Royce Merlin engine, the supercharger…

    A jet engine is a sort of engine that releases a quick moving jet of gas to produce thrust as per Newton's third law of motion. This expansive meaning of jet engines incorporates turbojets, turbofans, rockets, ramjets, pulse jets and pump-jets, yet in like but in common term usage, the term commonly refers to a gas turbine Brayton cycle engine, an type of engine with a revolving compressor fueled by a turbine, with the remaining energy providing thrust. In today’s modern age of aviation, jet…

    When studing liquid fuel combustion in gas turbine combustor, complicated principals including reactive flow, spraying, turbulent flow, multiphase flow, convective and radiative heat transfer and their interactions should be considered. In recent 40 years combustion chambers have continuously improved structurally. Present combustion chambers are generally devided to three main groups: Can type, Can Annular type, and Annular type chambers. Combustion chambers consist of components such as…

    To identify the preferred rotation direction, a blower performance analysis is needed. A blower is usually an enclosed multiblade rotor that compresses air to a higher discharge pressure. Blower is also known as fan, but, traditionally, blowers do not discharge air at low pressure as some fans do. Figure 1.6 – CENTRIFUGAL BLOWER Dryers use centrifugal blower, where air is radially discharged from the impeller, (or fan wheel), so turns 90° from its inlet to its outlet (Figure 1.6). Air…

    turbochargers are more efficient, have a higher peak power band and produces less strain on your engine. Turbochargers are more efficient than superchargers because of the way it compresses air. Superchargers are a belt driven turbine so they use the engine’s crankshaft to compress the air. This steals power from the engine because it need to spin the supercharger for it to work. However turbochargers are gas operated, so they compress air utilizing exhaust gases to spin a turbine. This greatly…

    In many people’s minds, the term “Fracking” only applies to the controversial extraction process and the environmental impact surrounding that process. Hydraulic Fracturing or “Fracking” for short is a process where chemicals and water are injected into wells to breakup rock formations that have gas or oil trapped in the rock itself. This process is specifically used for developing and extracting oil and natural gas from shale. While most people have heard the term “Fracking”, very few…
