The history of turbocharging?

Speaking of turbocharging, I believe many people are familiar with it. It is because of the introduction of such advanced technology that the history of automobile displacement determining power has been rewritten. Generally speaking, the displacement and power of an automobile engine are directly proportional. The most direct way to improve the engine output power is to increase the engine displacement. However, with the increase of displacement, the precision, weight and energy consumption of engine manufacturing also increase infinitely, and its shortcomings are also obvious. In order to solve this contradiction, automobile engineers who are full of research spirit innovatively use the engine supercharging technology, which makes it possible for automobile engines to obtain additional high-power power output. Let's take a concrete look at the history and usage of turbocharging. Speaking of turbocharging technology, it has a history of 100 years. 1905, Dr. Alfred Butch applied for the patent power-driven axial supercharger of the first turbocharger. The world's first exhaust gas-driven supercharger was produced in 19 12. The large-scale production of turbocharger appeared during World War II, and it was first applied to military aircraft by the United States. Saab is the first automobile manufacturer to apply turbocharger to automobile products. 196 1, the supercharger was tentatively installed in the car, but the effect after installation was not ideal due to the huge pressure and heat generated instantly. Saab from northern Europe and Sweden is the first automobile manufacturer to apply turbocharger to automobile products. Saab Saab 99, which came out in 1977, really made the application of turbocharging technology in automobile engines mature, and its arrival also announced the birth of a new era in automobile industry. Turbocharging technology rewrites the traditional concept that displacement determines power. Automobile engines output power by burning fuel in engine cylinders. Under the condition of a certain engine displacement, the most effective way to improve the output power is to provide more fuel for combustion, but it is difficult for the traditional engine intake system to provide enough air. Turbocharging is a technology to improve the intake capacity of the engine. It uses a special compressor to compress the gas in advance and then input it into the cylinder, so the quality of the gas will be greatly increased. After the engine is equipped with turbocharger, the maximum power can be increased by about 40%. The world's first new turbocharged direct injection gasoline engine has come out. This 2.0l FSI engine is suitable for many models produced by Volkswagen Group, such as A3, A4, A6 and Golf GTI. Manhumer has the honor to participate in this FSI development project of Volkswagen Group and has made important contributions to the development of new engines. Manhumer not only provides intake module for Audi engine production department, but also provides engine oil module and two-stage pressure regulating valve for crankcase ventilation. The 2.0l FSI engine was rated as the most influential engine of the year by 56 journalists from 26 countries. In the process of direct injection (stratified fuel injection /FSI) of this new turbocharged direct injection engine, the fuel is directly injected into the combustion chamber through the nozzle under high pressure. Like optional air circulation, FSI also helps to achieve the optimal air-fuel ratio. Combined with turbocharging, FSI has the characteristics of high performance and low fuel consumption. A series of data show that the direct injection engine improves the sports performance of Audi cars. Audi cars equipped with this engine have a horsepower of 70-200. When the speed is between 5, 100 and 000 rpm, Volkswagen GTI gets 200 horsepower from this engine. When the speed per minute is between 1, 800 ~ 5000 rpm, the maximum torque can reach 280 N/m in a fairly wide speed range. It can also accelerate the speed from 0 km/h to 100 km/h in seven seconds. The top speed of some models can even reach 240 km/h, although the speed is so fast, the average fuel consumption per 100 kilometers is only about 7.7 liters. Manhumer provides a technically complex intake manifold system for this new engine. It not only integrates the intake manifold, but also introduces the activated carbon filtration system, gasoline injection and throttle. In the combustion chamber, it also provides a descending piston for the optional air circulation system to optimize the airflow. The lever system driven by electricity effectively controls each swirl in each cylinder, and the valve is cast on the steel shaft injector to control the air flow in the combustion chamber and ensure the air-fuel ratio to reach the best state. When designing this system, the whole development team needs to choose 32 kinds of parts correctly. It took technicians only 15 months from research and development to mass production.
