• Inventions, which played a crucial role in the development of the automotive industry
The car itself is one of the greatest inventions of mankind. The history of the automotive industry has 134 years. All this time, manufacturers have sought to make the car better and better. It happened in this way every. There were frankly bad development, and there are inventions that become important milestones in automotive development. Such inventions - later in the review.
Removable rubber tire
That's really not that hard to imagine a modern car, so it is not tires. The first cars got wheels inherited from the horse-drawn carriages. Tire and wheel were one. This design was very heavy, unreliable and hard to irregularities.
And if the tire wears, the driver had to change the wheel entirely. We decided to issue the Michelin brothers, who in 1891 perfected the existing at that time, inflatable tires, making them removable. So a design that has been 129 years, is used in cars and replace it in the near future is not expected.
The diesel engine
The share of diesel cars was 46, 6% in Europe, according to the end of 2017. Such high performance is achieved because the modern diesel car is not inferior to gasoline in comfort and speed, but much more economical it. And it became possible thanks to the work of a German engineer Rudolf Diesel. The first functional copy of the diesel engine was developed in 1897. The efficiency of this engine was 26, 6%. It is significantly superior performance of the engine operating on the Otto cycle, which had a 20% efficiency. Despite this, the first diesel car appeared only in 1936. They became the Mercedes 260 D. Its motor - 2, 5-liter 4-cylinder diesel engine developed 45 l. from. at 3000 rev / min.
Today it seems obvious that in order to get the engine to turn the key in the ignition. However, once it became a real breakthrough. Made this breakthrough in 1911. American Charles Kettering invented the first electric starter. Prior to that, let the engine had his hands with a special handle, nicknamed "curve starter."
This pen was terribly uncomfortable, and at times even dangerous, because after running start spinning along with the engine, and often broke the brush, and then the driver's hands. The first car has received start-up "to the key", became Cadillac Model 30, introduced in 1912.
The seat belt has not just changed the automotive world, and has become the invention had saved millions of lives. In fact, the belts used on racing cars in the early XX century. And really in demand they became after the 1958 Swedish engineer Nils Bohlin invented the three-point belt design. This design proved to be very convenient in everyday use.
For the first time she appeared on the Volvo PV 544 in 1959. Over time, three-point belts began to equip their cars all manufacturers. And since the laws of many countries have begun to oblige to use seat belts, road deaths decreased by several times.
The inventors considered carburetor Donut Banks and János Csonka. They have patented his invention in 1893. The power supply system of the first cars were very imperfect. They do not take into account the features of the engine in different conditions, such as start, idling, acceleration. Motors because of this have been extremely uneconomical.
The invention has made possible the carburettor stable operation of the engine in different conditions. Of course, now the carbs are gone, but the injection system, widely used today, with the advent of the computer has become in fact a logical development of the invention, the Hungarian engineers.
