A lot of models now have "t", but i don't know how many turbine engines there are. What's our most common technology? What's the way they work
Turning to turbo-pressure technology, it's over 100 years old. In 1905, dr. Alfred buchi applied for a patent for the first turbine pressurizer - the power-driven axle pressurizer. By 1961, small cars had begun to test the installation of pressure boosters, but the installation had not worked optimally because of the enormous pressure and heat generated by the moment. Saabsabo, from northern sweden, is the first car manufacturer to apply turbine boosters to automobile products, saabsabo99, born in 1977, to make the engine really mature in the application of turbo-pressure technology, and to announce the birth of a new era in the automobile industry. Turbo pressurization techniques rewrite the traditional concept of "discharge size determines power"。
Turbo booster is actually an air compressor. It uses the exhaust gas from the engine as a power to drive turbines (in the vents) inside the turbines, which, in turn, drive the same wheel of leaves in the vents, which compress the fresh air from the air filter pipe and feed it into the cylinders. When the engine turns faster, the emission rate of the exhaust gas increases in step with that of the turbine, the air compression is increased, the engine's intake increases accordingly, and the engine's output power increases。
The greatest advantage of turbine boosting is that it can significantly increase engine power and rectangularity without increasing engine charge and without significantly increasing fuel consumption. So the advantage is that the turbine booster is popular. For the time being, there are four main types of boosters:
Waste gas turbine pressurization systems:
The most common is the waste gas turbine pressurization system, which has no mechanical connection to the engine, which is actually an air compressor, which increases gas intake by compressing air. It uses the exhaust inertial impulse from the engine to drive turbines in the turbine room, which in turn drive coaxial leaves, which send the air from the air filter pipe to increase pressure into the cylinder. When the engine turns faster, the emissions of the exhaust gas rise faster than the turn of the ship, the leaf wheel compresses more air into the cylinder, the pressure and density of the air increases to burn more fuel, and a corresponding increase in the amount of fuel increases the engine's output power。
In general, the power of engines and twisters increased by 20-30 per cent after the installation of the exhaust turbine booster. But there is also something that needs to be noted in the turbo technology, which is that pumps and turbines are connected by an axle, that is, rotors, exhaust-driven pumps discharged from engines, pump-driven turbine rotations, and turbo rotations that add pressure to the inflow system。
The pressure booster is installed on the exhaust side of the engine, so that the work temperature of the booster is high and the rate of the booster is very high at a rate of up to 100,000 turns per minute, so that the usual mechanical roller or ball bearings cannot work for the rotor, so that the turbine booster generally uses full-floating bearings, which are lubricants and cooled by cooling fluids。
Mechanical pressurization systems:
This device, which is installed on the engine and linked by belts to the engine's curve axis, obtains power from the engine's output axis to drive the voltage booster's rotor rotation, thereby blowing the air pressure into the airway. The advantage is that the turbine turns at the same speed as the engine, so there is no lag and the power output is very fluid. However, due to the fact that the engine is in the rotor axis, some of the power is consumed and the boosting is not very effective。
Airwave increase system:
Pulse waves using high-pressure exhaust gases force air compression. The system is very stressful and accelerant. The disadvantage, however, is that the whole device is heavy and not suitable for being installed in smaller cars。
Composite pressurization system:
In the case of exhaust turbines, which are used together with mechanical boosts, mechanical boosts contribute to the twisting output at low turn speeds, but the output at high turn speeds is limited; while voltage turbines have a strong power output at high turn speeds, but not at low turn speeds. The engine designers then envisaged combining mechanical and turbine boosting to address the respective deficiencies of the two technologies, while addressing the issues of low-speed twisting and high-speed power output。
The device is relatively numerous on high-power diesel engines, and the gasoline machine is less of a double-pressure system (complex pressurization system) with a popular 1. 4 tsi engine (which combines low-speed twist and high-speed power output). At low rotation, mechanical pressure provides most of the pressure booster pressure, and at 1,500 rpm, both pressurizers simultaneously provide pressure booster pressure. As the rate of rotation increases, turbine pressurizers provide greater power to engines, while the pressure pressure on mechanical pressors is gradually reduced。
The mechanical booster is controlled by an electromagnetic ioniser, which gathers together with the pumps. The system is used when all pressure boosters are provided by turbine boosters at speeds exceeding 3,500 rpm, when the mechanical booster is completely separated from the engine by the operation of the electromagnetic ioniser to prevent the consumption of engine power. Its high engine output power, low fuel consumption and low noise are just too complex a structure, high technical content and difficult to maintain and therefore difficult to universalize。
