German engineer Karl Benz introduced the world’s first automobile in 1886, receiving patent No. 37435 for a “gas-powered vehicle.” This three-wheeled crew, which is called Patent-MotorwagenThe company was the starting point of the global automotive revolution, forever changing the logistics and way of life of mankind. Unlike earlier steam engines, this unit used a lightweight and powerful gasoline internal combustion engine, which allowed to start mass production. Exactly. 1886 It is officially considered the year of birth of the car, although experiments with steam carts were conducted long before that.
The creation of the machine required the development of fundamentally new nodes, since there were no ready-made solutions for ground transport on liquid fuel. Benz independently designed the ignition system, carburetor and differential, without which it was impossible to stable the mechanism. The world's first car had an engine capacity of 954 cubic centimeters and developed a speed of 16 km / h, which by the standards of the XIX century was considered a dizzying indicator.
The history of the emergence of this miracle of technology is full of technical difficulties and doubts of contemporaries who did not believe in the future of "self-propelled wagons". The inventor’s wife, Berta Benz, played a key role in popularizing the invention by making the first long-distance car run in history without her husband’s knowledge. This act proved the practicality of the machine and attracted the attention of investors, opening the way to mass production.
Technical characteristics and engine design
Heart. Patent-Motorwagen It was a single-cylinder four-stroke engine running on ligorine fuel. The design was simplified to ensure reliability, but it included all the necessary components of a modern internal combustion engine. The power of the installation was only 0.9 horsepower at 400 rpm, which required the use of a temporary drive to transmit torque.
The cooling system operated on the principle of a thermosiphon, where water circulated naturally without using a pump. A large vertical water tank was located at the back and served as a radiator at the same time. To ignite the mixture, a potassium ignition with a platinum tube was used, which was red-hot from the external burner.
⚠️ Attention: Early versions of the engine did not have a throttle valve in the usual sense, power control was carried out by changing the moment of ignition, which made the engine unstable at low revs.
Key features of the power unit included:
- 🔥 Using a horizontal cylinder to lower the center of gravity.
- ⚙️ The use of a large flywheel to smooth out the unevenness of rotation.
- 🛢️ An evaporative carburetor where fuel was mixed with air due to thrust.
- 🌡️ Lack of a pressure lubrication system, the oil was supplied with wick.
Transmission and chassis of the tricycle
The world’s first car had a three-wheeled circuit, where two large rear wheels were driving, and one small front was responsible for driving. This configuration was chosen because of the lack of effective steering mechanisms for the pair of wheels, known today as Ackermann steering geometry. The transmission of torque from the engine to the rear axle was carried out through a system of belts and chains.
The transmission included a cone clutch and a two-speed gearbox, although in fact there was no second gear - there was only a direct gear and neutral. A simple belt brake acting on the drive shaft was used to stop. Wooden wheels with solid rubber tires provided acceptable grip, but cushioning was absent completely.
Differential design
Benz applied a differential with conical gears, which allowed the wheels to rotate at different speeds when turning, preventing skids and breakage of the axles. It was a revolutionary decision for the time.
The table below shows a comparison of the parameters of the running gear Patent-Motorwagen with later models of the early XX century:
| Parameter | Benz Patent-Motorwagen (1886) | A typical 1910 car |
|---|---|---|
| Number of wheels | 3 | 4 |
| Wheel material | Steel-rimmed tree | Wood/Steel with spokes |
| Tyre type | Solid rubber | Pneumatic |
| Driver. | Back axle chain | driveshaft |
Berta Benz's role in the history of the automotive industry
It was the woman who demonstrated to the world the practical value of her husband's invention. In August 1888, Bertha Benz, without notifying Karl, took a car and two sons and went from Mannheim to Pforzham to her mother. The distance of 106 kilometers has not been overcome by anyone on a self-propelled cart before.
On the way, she had to show the wonders of engineering ingenuity. When the fuel ran out, she bought it from a pharmacy store, as gasoline was then sold as a cleaning agent. She cleaned the clogged fuel supply tube with a hat pin, and wrapped the broken insulation of the wire with her garter. These improvised solutions later formed the basis for constructive changes.
After this trip, Karl Benz made a number of improvements:
- 🚗 An additional gear is added to overcome the lifts.
- 🛑 More effective brake mechanisms have been installed.
- 🛣️ Increased wheel diameter for better passability.
- 🔇 Silencers have been introduced to reduce exhaust noise.
The evolution of the internal combustion engine
The engine of the first car has come a long way from the primitive single-cylinder unit to complex multivalve systems. The principle of operation laid down by Benz is based on the Otto cycle, where the combustion of the mixture occurs at a constant volume. Early motors suffered from low efficiency and overheating, requiring constant operator supervision.
With the development of metallurgy and processing technologies, it was possible to increase the degree of compression and engine speed. The advent of an electric ignition system replaced unreliable kettle tubes, making the start instantaneous. The introduction of float carburetors allowed to more accurately dose the fuel-air mixture, improving efficiency.
⚠️ Attention: The use of lygroin mixtures in the first engines was due to the fact that gasoline was considered a dangerous waste of oil refining and cost less than kerosene.
Interesting fact: The first Benz engine was started manually by unwinding the flywheel, since the starters did not yet exist. This required considerable physical strength.
Social influence and legal regulation
The appearance of the world’s first car caused not only delight, but also fear among the inhabitants and authorities. Horses shunned the roaring cars, frightened by the smell and noise. In some cities in England and Germany, laws were introduced limiting the speed of "steam carts" to the speed of a pedestrian, and a man with a red flag was to walk in front of the car.
However, the potential of the new transport was obvious for the industry. Active construction of roads with hard surfaces, which was not previously required for horse-drawn transport, began. The first gas stations, garages and repair shops appeared. The legal status of the car as a vehicle was only secured after a number of legal proceedings.
The success of the car depended not only on technology, but also on the change in infrastructure and public opinion, which took several decades.
Extant specimens and museums
Very few examples of early Benz models have survived to this day. The original 1886 Patent-Motorwagen burned down in the workshop, but the 1888 model is preserved, which is in the German Museum in Munich. This vehicle is considered the oldest surviving car in the world with an internal combustion engine.
Collectors and museums around the world hold the rarest artifacts of the era. Recovery of such machines requires unique knowledge and hand-made parts, as the drawings are often lost. The cost of original cars of that era at auctions is estimated in millions of dollars.
☑️ What to check for a copy of Patent-Motorwagen
Heritage and modern technology
The principles laid down by Karl Benz underpin the billions of cars produced over the past hundred years. Despite the advent of electric vehicles and hybrids, spark-ignition engine design remained dominant for more than a century. Engineering thought, launched in 1886, continues to evolve in the areas of efficiency and environmental friendliness.
Today we are witnessing a new round of evolution, comparable in importance to the invention of the first car. However, the fundamental problems of control, braking and torque transmission were solved at that time. History Patent-Motorwagen It reminds us that even the most sophisticated technologies start with the simple idea and the tenacity of the inventor.
What was the maximum speed of the first car?
The top speed of the Benz Patent-Motorwagen was about 16-18 km/h. It was much faster than the stride, but slower than a good horse harness in the short distance.
Why did the first car have three wheels?
The three-wheeled circuit was chosen to simplify the steering design. The mechanism of turning the two front wheels (axelbant) was technically more complex and heavier than the control of a single rotary wheel.
Where can I see the original car?
The original 1886 has not survived. The oldest existing specimen from 1888 is on display at the Deutsches Museum in Munich. Copies can be seen at the Mercedes-Benz Museum in Stuttgart.
What was Bertha Benz's first trip?
The first ever long-distance car trip was about 106 kilometers one way from Mannheim to Pforzham. The return route was laid down on another route, which increased the total mileage to more than 200 km.
