Fritz Huber (engineer)
Fritz Huber (1881-1942) was a German mechanical engineer and designer of the Lanz Bulldog tractor. Biography Fritz Huber was born on 8 March 1881 in Wasserburg am Inn. He came from an old family of engineers. In Munich, he first attended the industrial school, then he began studying at the local technical college. He successfully completed his studies in 1903 and went on to work in France and Switzerland. After his return to Germany, he got a job at the Grade company in Magdeburg, where he devoted himself to the construction of high-quality two-stroke engines. He also built the first hot-bulb engines at the Climax plant in Vienna and improved their running characteristics with adjustable injectors and improved mass balance. On 20 September 1916, he obtained employment with Heinrich Lanz AG in Mannheim. He constructed gasoline-powered tractors for the German army in the First World War. Between 1918 and 1921 he developed a single-cylinder hot-bulb engine for stationary work. Thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lanz Bulldog
The Lanz Bulldog was a series of tractors manufactured by Heinrich Lanz AG in Mannheim, Baden-Württemberg, Germany. Production started in 1921 with the Lanz HL, and various versions of the Bulldog were produced up to 1960, one of them being the Lanz Bulldog D 9506. John Deere purchased Lanz in 1956 and started using the name "John Deere Lanz" for the Lanz product line. A few years after the Bulldog was discontinued the Lanz name fell into disuse. The Lanz Bulldog was one of the most popular German tractors, with over 220,000 of them produced in its long production life. The name "Bulldog" is widely used in Germany as a synonym for tractors even today, especially in Bavaria. Engine The Lanz Bulldog was built with a single-cylinder, two-stroke Akroyd engine – the so-called Bulldog engine – that was designed by Fritz Huber. The Bulldog engine was installed horizontally, with the ignition device – the hot bulb – facing forward. It has crankcase scavenging, and intak ...

Wasserburg Am Inn
Wasserburg am Inn ( Central Bavarian: ''Wassabuag am Inn'') is a town in Rosenheim district in Upper Bavaria, Germany. The historic centre is a peninsula formed by the meandering river Inn. Many Medieval structures remain intact, giving the city a unique view. History The town was first mentioned in a document (now considered to be a fake) in 1137, when Hallgraf Engelbert moved his residence from the nearby castle Limburg to his "Wasserburg" (Water Castle). It is one of the most historic towns of Old Bavaria – somewhat older than Munich, continually fought over by the Bavarian nobility and, up to the 16th century, on an equal footing with larger cities. The privileges afforded by this enabled the salt trade to flourish right into the 19th century. At the junction of the main overland route with the main water route, Wasserburg became the most important trade centre with the Balkans, Austria and Italy, a means of attaining power and wealth for the shipping owners and merchants ...

Munich
Munich ( ; german: München ; bar, Minga ) is the capital and most populous city of the German state of Bavaria. With a population of 1,558,395 inhabitants as of 31 July 2020, it is the third-largest city in Germany, after Berlin and Hamburg, and thus the largest which does not constitute its own state, as well as the 11th-largest city in the European Union. The city's metropolitan region is home to 6 million people. Straddling the banks of the River Isar (a tributary of the Danube) north of the Bavarian Alps, Munich is the seat of the Bavarian administrative region of Upper Bavaria, while being the most densely populated municipality in Germany (4,500 people per km2). Munich is the second-largest city in the Bavarian dialect area, after the Austrian capital of Vienna. The city was first mentioned in 1158. Catholic Munich strongly resisted the Reformation and was a political point of divergence during the resulting Thirty Years' War, but remained physicall ...

Magdeburg
Magdeburg (; nds, label= Low Saxon, Meideborg ) is the capital and second-largest city of the German state Saxony-Anhalt. The city is situated at the Elbe river. Otto I, the first Holy Roman Emperor and founder of the Archdiocese of Magdeburg, was buried in the city's cathedral after his death. Magdeburg's version of German town law, known as Magdeburg rights, spread throughout Central and Eastern Europe. In the Late Middle Ages, Magdeburg was one of the largest and most prosperous German cities and a notable member of the Hanseatic League. One of the most notable people from the city is Otto von Guericke, famous for his experiments with the Magdeburg hemispheres. Magdeburg has been destroyed twice in its history. The Catholic League sacked Magdeburg in 1631, resulting in the death of 25,000 non-combatants, the largest loss of the Thirty Years' War. During the World War II the Allies bombed the city in 1945 and destroying much of it. After World War II the city b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-stroke Engine
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later t ...

Hot-bulb Engine
The hot-bulb engine is a type of internal combustion engine in which fuel ignites by coming in contact with a red-hot metal surface inside a bulb, followed by the introduction of air (oxygen) compressed into the hot-bulb chamber by the rising piston. There is some ignition when the fuel is introduced, but it quickly uses up the available oxygen in the bulb. Vigorous ignition takes place only when sufficient oxygen is supplied to the hot-bulb chamber on the compression stroke of the engine. Most hot-bulb engines were produced as one or two-cylinder, low-speed two-stroke crankcase scavenged units. History Four-stroke Hornsby-Akroyd oil engine The concept of this engine was established by Herbert Akroyd Stuart, an English inventor. The first prototypes were built in 1886 and production started in 1891 by Richard Hornsby & Sons of Grantham, Lincolnshire, England under the title Hornsby Akroyd Patent Oil Engine under licence.Herbert Akroyd Stuart, ''Improvements in Engines ...

Gasoline
Gasoline (; ) or petrol (; ) (see ) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines (also known as petrol engines). It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. On average, U.S. refineries produce, from a barrel of crude oil, about 19 to 20 gallons of gasoline; 11 to 13 gallons of distillate fuel (most of which is sold as diesel fuel); and 3 to 4 gallons of jet fuel. The product ratio depends on the processing in an oil refinery and the crude oil assay. A barrel of oil is defined as holding 42 US gallons, which is about 159 liters or 35 imperial gallons. The characteristic of a particular gasoline blend to resist igniting too early (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating, which is produced in several grades.

First World War
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Arch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
