Functional because quite a few of these were actually produced and used all over Paris in several printing presses and looms. In , Lenoir installed this engine in a vehicle and named it the 'Hippomobile'. He drove this vehicle for nine kilometers from Paris to Joinville-le-Pont, and back. He used a turpentine derivative as fuel; thus, it was the first vehicle to pack the liquid-fuelled internal combustion engine. However, Lenoir's Hippomobile could not serve the need for speed.
Its two-stroke engine was capable of generating only rpm and had an average speed of 6 kilometers per hour. Though Lenoirs' engine was not very successful in the automobile industry, the reduced size and weight impressed many.
After which, Nicolaus August Otto, a German Engineer, took on the task of making this engine more efficient. He started exploring the potentiality of Ethyl Alcohol as fuel and installing four strokes to improve engine efficiency. After twelve years of rigorous experimentation and a number of failures, in , he succeeded in developing a functional four-stroke engine based on the principles of Alphonse Beau de Rochas and established the principles of intake, compression, combustion, and exhausts.
To date, all internal combustion engines in cars and motorcycles function on the principles stated by Otto. Otto's engine and its developments were undoubtedly more potent than the Lenoir's; however, its weight became a matter of concern for automobiles.
The pressure generated by the explosion pushes the piston down very quickly in the combustion stroke. In the fourth step, the piston quickly moves up again and expels the burned gases from the cylinder through a valve. The engine was first made ready for mass protection by Gottlieb Daimler and Wilhelm Maybach, who had been in the employ of Deutz AG since The engine was a great success and sold very well.
But it was still too heavy for mobile use. After falling out with Otto, Daimler left Deutz AG in late and set up an experimental workshop in Cannstadt, where he was soon joined by Maybach.
Daimler's goal was the development of small, fast-running internal combustion engines that would be able to power vehicles on land and water. As early as , he filed a patent application for an improved single-cylinder four-stroke engine which he had developed jointly with Maybach. It was small, relatively light and ran on petrol: ideal for use in a vehicle. In , they unveiled their first completely self-propelled vehicle, the 1.
So, it was no wonder that, at the turn of the century, the automobile was still an extravagance reserved for the very wealthiest ten thousand. But even though only a few vehicles were initially rattling along the roads, they were increasingly stirring up controversy and also causing accidents.
But it would take a few more years for the possession of a driving licence to be made mandatory in Germany. In Prussia, the first basic regulation for the inspection of motor vehicles and their drivers was enacted by a ministerial decree of 29 September And yet, a regulation for the inspection of drivers and vehicles throughout the German Reich was still not in sight, even though the situation was becoming more urgent year by year.
This was because the fledgling technology was susceptible to breakdown, and many drivers were not familiar with their conveyances. In proportion to the number of automobiles on the road, the risk of falling victim to an accident was nearly sixty times as high as it was in The state had to respond. They were initially able to carry out this task in addition to their other inspection duties, because, after all, in comparison to steam boilers, the number of cars and their drivers was still vanishingly small.
That this would soon change was in no small measure down to Henry Ford. In , the American car magnate installed assembly lines in his factory in Highland Park, Michigan, thereby revolutionising the manufacturing process for his Model T. As the production costs plunged, so too did the prices. Other automakers, too, learned from the Ford principle and said goodbye to manual production. As the number of cars grew, so too did the need for inspections.
As the boiler monitoring associations were now also carrying out safety tests of lifts and electrical systems, the decision was made to change their name in At this time, however, the requirement was for cars to be inspected and approved once only, at the time of first registration.

Instead of heating the fuel on the outside, a mixture of fuel and oxygen is injected into the engine and a spark ignites the fuel that causes it to make tiny explosions or combustions.
A car engine is made up of moving pistons and fixed cylinders. Once the fuel is ignited, the small explosion forces the pistons to go through the cylinder which then drives the crankshaft. The crankshaft then converts the energy into rotational energy, which enables the car wheels to turn. Since the early 17th century, several scientists came close to creating an internal combustion engine. However, in , a man named Jean Joseph Etienne Lenoir patented the first commercial internal combustion engine.
At the time, the engine only had one cylinder, which gave it a tendency to overheat. But it was able to power a three-wheeled car that could go about two miles per hour.
