New Audi A1 (render)
Audi is currently working on the second-generation A1 and if reports prove accurate, it is set to be a significant improvement over the current car. Speaking to Autocar, inside sources allege that Audi wants the new A1 to trump the Mini hatchback in all areas and intends on accomplishing this goal with a host of upgrades. Most significantly, the new Audi A1 will be underpinned by a new platform and be available with adaptive damping control as part of the new suspension system. These changes are said to be enough to offer better handling and more comfort than the outgoing car and will inevitably be welcomed by prospective hatchback buyers. Sadly, for those that fell in love with the tiny footprint of the A1, the new car will be larger with the wheelbase alone being lengthened by 94 mm. What鈥檚 more, the three-door version will no longer be offered. Additionally, we know the new A1鈥檚 exterior will be thoroughly redesigned to fit in line with the brand鈥檚 latest styling language, recently showcased by the latest A8. In terms of engines, a turbocharged 1.0-liter three-cylinder with 113 hp will replace the current 1.2-liter turbo-four. Additionally, a new 1.5-liter four will take the place of the existing 1.4-liter four-cylinder while the new S1 will get a 2.0-liter four-cylinder with 250 hp rather than the 1.8-liter of today.
Combustion Chamber : The air, at high pressure from the regenerator is fed to the combustion chamber where it is heated up by burning oil. The temperature of chamber may go up to 3000 degree Fahrenheit and the combustion gases are cooled to about 1500 degree Fahrenheit before being delivered to the gas turbine. Gas Turbine : The mixture of gases at high temperature and pressure, from the combustion chamber, moves to the gas turbine where it expands and delivers mechanical energy. The temperature of the exhaust gases from the turbine is about 900 F. The gas turbines are normally of axial flow type. Alternator : The gas turbine is coupled to an alternator. The mechanical energy of the gas turbine is converted into electrical energy by the alternator. Starting Motor : Compressor must be driven before it supplies compressed air to the turbine. A motor is operated using either battery supply in case of an isolated system or regular supply.
In combined cycle power plants, the hot gas is used to produce steam as well and there is a steam turbine in addition to the gas turbine. Since there is better energy utilization in this case, the overall efficiency increases considerably. In the diesel electric power plant, diesel oil is used as fuel. The block schematic and different parts of diesel electric plants are explained below. Diesel Engine : This is the main component of the diesel electric power plant which develops power. They may be 4 strokes or 2 stroke engine. 4 stroke engines has lower fuel consumption, more flexibility, better scavenging and higher efficiency than 2 stroke. Cylinders are arranged in V shape to make the engine more compact. 6 to 8 cylinders are commonly used. Speed is in the range of 500-1000 rpm. The diesel engines are compression ignition type. Air filter and Supercharger : The function of air filter is to remove the dust from the air, which is taken by the engine. The function of supercharger is to increase the pressure of air supplied to the engine to increase the power of the engine.
The supercharger is driven by the engine. Exhaust system : This includes silencer and connecting ducts. The temperature of exhaust gases are really high that heat is used for heating the oil or air supplied to the engine. Fuel System : This includes fuel storage tank, fuel pump, fuel transfer pump, strainers and heaters. Strainers are provided to remove the suspended impurities. Heaters are required to heat the oil, especially during winter seasons. Cooling System : This includes oil pumps, oil tanks, filters, coolers and connecting pipes. The function of the lubricating system is to reduce the friction of moving parts and to reduce the wear and tear of the engine parts. The life of engine and its efficiency largely depends on the lubricating system. Starting System : This includes compressed air tanks. The function of this system is to start the engine from cold by supplying the compressed air.
Governing System : Their function is to maintain the speed of the engine constant irrespective of load on the plant. This is done by varying fuel supply to the engine according to load. Diesel Engine Generator : The generators used in diesel power plants are of rotating field, salient pole construction, speed ranging from 214 to 1000 rpm and capacities ranging from 25-5000 kVA at 0.8 power factor lagging. Generators are coupled directly to diesel engine. They are provided with voltage regulators to allow voltage regulation. The excitation is usually provided at 115 to 230 V from a DC exciter, usually coupled to the engine shaft through a belt.

You want a best used engine please visit our site. Oh my, what's with me today? I thought from your hub title I would be reading about plants as in foliages, trees and leaves! Anyway, this hub is really well explained. Helps us to better appreciate the valuable electricity that makes our lives better. WOW what a wealth of information and great graphics. I learned a great deal about different plants used for generation of electric power. Thanks for all the fantastic research.
