The same year, Sir Douglas Clerk successfully created the first two-stroke engine.

Thanks to the great minds of several 19th-century inventors, the internal combustion engine is one of the most popular, efficient engines. It continued evolving throughout the 20th century to become more efficient.
In , fuel injectors were added to help engines run smoother and eliminate the need to adjust a choke to make the car start. About a decade later, turbocharged engines were introduced to the auto industry. Other features, like compression ratios and cylinder deactivation, were later added to engines to make them more powerful and efficient. The internal combustion engine has come a long way.
However, with the way technology is transforming the auto industry, we have no doubt the internal combustion engine will continue to evolve. Home Cars. How does an internal combustion engine work? This engine was shortly followed by a hydrogen-oxygen-powered combustion engine invented by Francois Issac De Rivaz, in which he used electric spark as the ignition mechanism. Rivaz went on further and installed his engine in a carriage, which became the world's first automobile powered by internal combustion.
A few years later, in , Samuel Brown patented the first internal combustion engine that could be applied industrially. Also known as 'The Gas Vacuum Engine', it used atmospheric pressure to work.
He demonstrated its efficiency in running a carriage and a boat, and in this engine successfully pumped water to the upper level of the Croydon Canal in England. These inventions drew the interest of several innovators, and in the following years, a number of unique developments came into existence.
Again in , Lemuel Wellman Wright of the United Kingdom created a table-type double-acting gas engine with a water-jacketed cylinder. William Barnetts' engine, developed in , is believed to be the first engine that implemented in-cylinder compression. A few other developments took place in the coming years, but the grand breakthrough came in from the hands of Jean Joseph Etienne Lenoir. He invented a gas-fired internal combustion engine that is regarded as the first functional combustion engine.
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.
One thing, however, is certain: thereafter, the Benz patented motor car began its slow but sure uphill journey to commercial success. By , 69 vehicles had been sold, mainly in the US, England and, especially, France, where, thanks to good roads, the first car enthusiasts were not quite so thoroughly shaken about. The number of employees had risen to over , a tenfold increase. Carl Benz was the first entrepreneur to introduce a working automobile with a combustion engine onto the market.
And yet, at the end of the 19th century, the development of the motor car found itself at something of a crossroads. Large numbers of engineers, innovative tinkerers and inventors were experimenting with engine technologies and building the first steam cars and electric cars, alongside vehicles with internal combustion engines.
Unlike in the steam engine, the fuel was not burnt outside the engine and the resulting heat directed into the cylinders. The kinetic energy was instead generated by explosive combustion inside the engine.
However, the hippomobile never made it beyond the development stage: It was too heavy, and its two-stroke engine was capable of no more than revolutions per minute. Benz based the development of this engine on the work of Nicolaus August Otto - who had himself used the Lenoir gas engine as a template for further development. The Lenoir gas engine, patented in , caused a veritable sensation at the time and was seen as the first alternative to the large and heavy steam engine.
Unlike the latter, it did not need to be preheated for quite so long before it could be put to work. Supplied with gas from the municipal grid, the quiet motor was deployed to drive such equipment as printing presses and looms.
However, its construction meant that it needed a very powerful water-cooling system and, above all, huge volumes of gas. Its efficiency was between three and four percent, which meant that it could convert only a very small proportion of the energy contained in the fuel into mechanical energy. Salesman and technical autodidact Nicolaus August Otto recognised both the potential and the limits of this machine and set about refining it.
In , he commissioned the construction of a replica Lenoir engine and established that it would work better if fuelled with ethyl alcohol. In the same year he and with his brother Wilhelm submitted a patent application for an alcohol evaporator.
To justify the application, they cited the independence of the gas network of internal combustion engines and raised the possibility of self-propelled conveyances on country roads. In the following year he began experimenting with the four-stroke engine, a principle that had been theoretically described and patented by French engineer Alphonse Beau de Rochas in the same year, completely independently of Otto.
Otto's idea was to compress the mixture of air and gas to the maximum possible extent. This would make it possible to reduce the proportion of gas and, thereby, consumption. The piston would, however, be required to move up and down twice to perform one unit of work. In practice, controlling the combustion was still causing Otto all sorts of problems, and the experiments were culminating in the destruction of the engines.
It would take twelve years, until , to produce the first functional four-stroke engine in the Deutz AG gas engine factory. He established the principle of intake, compression, combustion and exhaust according to which every internal combustion engine in either cars or motorbikes still functions: In the first stroke, the piston moves down and sucks a mixture of air and fuel into the cylinder through a valve. In the second step, the piston moves upwards, compressing and heating the mixture in the process.
At the moment of maximum compression, the mixture is ignited by the spark from a spark plug. 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.
