Lanz HL
The Lanz HL, also known as Lanz Bulldog HL and Lanz Bulldog HL 12, is an agricultural machine and tractor made by Heinrich Lanz & Co. OHG. It was developed by German engineer Fritz Huber and is the first Lanz tractor to feature the "Bulldog" Akroyd engine. Thus, it is the first series production Lanz Bulldog. The Lanz HL was introduced at the 1921 DLG agriculture fair in Leipzig and stayed in production until 1927. In total, more than 6,000 units were made. The HL Bulldog engine was also sold as a stationary engine; this article primarily describes the HL agricultural tractor. Technical description The Lanz HL is an agricultural machine that resembles, in its default configuration, an agricultural tractor. Nonetheless, the Lanz HL was not primarily designed as a tractor; it is rather a self-propelled farm implement motor. Various different versions were made, with rubber or steel wheels. It uses a frameless design with the rear axle flange-mounted to a housing shaped like a "h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinrich Lanz AG
Heinrich Lanz AG is a former agricultural machinery manufacturer from Mannheim, Germany. Its tractors were sold bearing the LANZ brand. LANZ won numerous awards at the Strasbourg Agricultural Fair in 1866; namely four Gold, five Silver, and three Bronze. The Heinrich Lanz AG company, and its LANZ brand name was ultimately acquired by way of a merger in 1956 by the American agricultural machinery manufacturer Deere & Company, and became the John Deere Works Mannheim (JDWM). History The Heinrich Lanz Company was founded in 1859 by German engineer Heinrich Lanz. It produced the first steam-powered stationary threshing machines in 1879, and the first crude oil fuelled tractor; the Lanz Bulldog, in 1921. In 1956, Heinrich Lanz AG merged with Deere & Company of Moline, Illinois Illinois ( ) is a U.S. state, state in the Midwestern United States, Midwestern United States.

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 ...

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. This ... [...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 intake p ...

Evaporative Cooling (engine)
Radiators are heat exchangers used for cooling internal combustion engines, mainly in #Automobiles and motorcycles, automobiles but also in #Aircraft, piston-engined aircraft, Diesel locomotive, railway locomotives, #Automobiles and motorcycles, motorcycles, Diesel generator, stationary generating plant or any similar use of such an engine. Internal combustion engine cooling, Internal combustion engines are often cooled by circulating a liquid called ''#Engine_coolant, engine coolant'' through the engine block, and cylinder head where it is heated, then through a radiator where it loses heat to the atmosphere, and then returned to the engine. Engine coolant is usually water-based, but may also be oil. It is common to employ a water pump to force the engine coolant to circulate, and also for an axial fan to force air through the radiator. Automobiles and motorcycles In automobiles and motorcycles with a liquid-cooled internal combustion engine, a radiator is connected to ch ...
