Which country in the world invented the turbocharged engine? Which country invented the world's first turbocharged engine?

Switzerland.

Who is the inventor of turbocharger? It is generally recognized as Bosch, a Swiss engineer, who declared this patent in 1905. It was mainly used for aircraft engines and tank engines at that time. It was not until 196 1 that General Motors of the United States installed a turbocharger on a certain model it produced.

The 1970s became the turning point of turbocharging, and Porsche 9 1 1 with supercharged engine came out. However, SAAB in Sweden is the only company that rejuvenates turbocharging technology. The Saab 99 launched in 1977 spread the turbocharging technology more widely, but the turbocharger at that time was only assembled on the gasoline engine of the car.

Main points of use

1. Don't slam on the accelerator after the car engine starts. You should rest for three minutes first. This is to increase the temperature of the engine oil, improve the fluidity and make the turbocharger fully lubricated. Then you can increase the engine speed and start driving. This is especially important in winter, and it takes at least five minutes to warm up the car.

2. After the engine runs at high speed for a long time, it cannot be turned off immediately. The reason is that some oil is supplied to the turbocharger rotor bearing for lubrication and cooling when the engine is working. When the running engine stops suddenly, the oil pressure drops to zero quickly, the oil lubrication will be interrupted, and the heat inside the turbocharger cannot be taken away by the oil.

3. Pay attention to the choice of engine oil. Due to the function of turbocharger, the quality and volume of air entering the combustion chamber are greatly improved, and the engine structure is more compact and reasonable. The higher compression ratio makes the engine work harder.

4. The oil and filter must be kept clean to prevent impurities from entering, because the fit clearance between the rotating shaft and the shaft sleeve of the turbocharger is very small. If the lubricating ability of the oil decreases, the turbocharger will be scrapped prematurely.
