38-481: Edenbergen is a village and a former municipality in the district Augsburg in Bavaria , Germany . Since 1 January 1978, it is part of the municipality of Gersthofen . Edenbergen incorporates the hamlets of Gailenbach and Gailenbacher Mühle . Edenbergen is located at an altitude of 476 meters (1,562 feet) above sea level on a ridge between Böglebach to the north and Gailenbach to the south. These two creeks run through

76-621: A barrow. He attended a Protestant -French school and soon became interested in social questions and technology. Being a very good student, 12-year-old Diesel received the Société pour l'Instruction Elémentaire bronze medal and had plans to enter Ecole Primaire Supérieure in 1870. At the outbreak of the Franco-Prussian War the same year, his family were deported to England, settling in London, where Diesel attended an English-speaking school. Before

114-640: A daughter of a Nuremberg merchant, in Paris in 1855 and became a leather goods manufacturer there. Shortly after his birth, Diesel was given away to a Vincennes farmer family, where he spent his first nine months. When he was returned to his family, they moved into the flat 49 in the Rue de la Fontaine-au-Roi . At the time, the Diesel family suffered from financial difficulties, thus young Rudolf Diesel had to work in his father's workshop and deliver leather goods to customers using

152-904: A man floating in the Eastern Scheldt . The body was in such an advanced state of decomposition that it was unrecognisable, and they did not retain it aboard because of heavy weather. Instead, the crew retrieved personal items (pill case, wallet, I.D. card, pocketknife, eyeglass case) from the clothing of the dead man, and returned the body to the sea. On 13 October, these items were identified by Rudolf's son, Eugen Diesel, as belonging to his father. Five months later, in March 1914, Diesel’s wife, Martha, went missing in Germany. There are various theories to explain Diesel's death. Some, such as Diesel's biographers Grosser (1978) and Sittauer (1978) have argued that he died by suicide. Another line of thought suggests that he

190-537: A proportion of women of 48.7 percent. At that time, the population density of Edenbergen was 69 inhabitants per square kilometer (180 inhabitants per square mile). Roman Catholics comprise most of the population in Edenbergen and belong to the parish of Batzenhofen, a village half a mile east of Edenbergen and part of the Diocese of Augsburg . There is no church building in Edenbergen, but three chapels dedicated to

228-515: A small Diesel engine was exhibited by the Otto company which, on the suggestion of the French Government, was run on arachide [peanut] oil, and operated so well that very few people were aware of the fact. The motor was built for ordinary oils, and without any modification was run on vegetable oil. I have recently repeated these experiments on a large scale with full success and entire confirmation of

266-401: A steam engine. His work in engine design was driven by the goal of much higher efficiency ratios. As opposed to outside ignition applied against internal air and fuel mixture , air was compressed internally within the cylinder whilst heating, in order for the fuel to establish contact the air immediately before the compression period would end, thus igniting on its own. Therefore, the engine

304-470: A very important replacement for the steam piston engine in many applications. Because the Diesel engine required a more robust construction than a gasoline engine, it saw limited use in aviation . However, the Diesel engine became widespread in many other applications, such as stationary engines , agricultural machines and off-highway machinery in general, submarines , ships, and much later, locomotives , trucks, and in modern automobiles. Diesel engines have

342-948: The Augsburg-Westliche Wälder Nature Park , which is a hilly region covered with forests. It is sparsely populated and crisscrossed by brooks, flowing either eastwards to the Lech or northwards to the Danube . The Lech forms the eastern border of the district. The six cities (see below) are all situated in the easternmost part of the district, mainly in the vicinity of Augsburg. The western forest region consists of small villages. The coat of arms displays: Market towns 48°25′N 10°50′E  /  48.42°N 10.83°E  / 48.42; 10.83 Rudolf Diesel Rudolf Christian Karl Diesel ( English: / ˈ d iː z əl ˌ - s əl / , German: [ˈdiːzl̩] ; 18 March 1858 – 29 September 1913)

380-768: The Blessed Virgin Mary . Augsburg (district) In Roman times the Via Claudia connected the city of Augsburg and Italy. In 233 the Alamanni broke through the limes , and the Roman rule over Swabia was ended. During the time of the Holy Roman Empire Augsburg was a bishopric principality. The city and the adjoining regions became subordinate to Bavaria after the Napoleonic Wars . The district of Augsburg

418-565: The Carnot cycle . In 1892, after working on this idea for several years, he considered his theory to be completed. In the same year, Diesel was given the German patent DRP 67207. In 1893, he published a treatise entitled Theory and Construction of a Rational Heat-engine to Replace the Steam Engine and The Combustion Engines Known Today , that he had been working on since early 1892. This treatise formed

456-653: The Vickers shipyard in Montreal and was responsible for a sudden acceleration in its ability to produce a successful Diesel engine for submarines. Given the limited evidence at hand, his disappearance and death remain unsolved. In 1950, Magokichi Yamaoka , the founder of Yanmar , the diesel engine manufacturer in Japan, visited West Germany and learned that there was no tomb or monument for Diesel. Yamaoka and people associated with Diesel began to make preparations to honour him. In 1957, on

494-734: The United States. He was inducted into the Automotive Hall of Fame in 1978. On the evening of 29 September 1913, Diesel boarded the Great Eastern Railway steamer SS Dresden in Antwerp on his way to a meeting of the Consolidated Diesel Manufacturing company in London. He took dinner on board the ship and then retired to his cabin at about 10 p.m., leaving word to be called the next morning at 6:15 a.m., but he

532-569: The bank and metal businesses of the merchant families Fugger and Welser. The financial power of these families fostered Augsburg's position as a cosmopolitan city, as a city of emperors and parliaments. It was a creative center for famous painters, sculptors and musicians. Augsburg is the birthplace of the Holbein family of artists and print-makers, notably Hans Holbein the Elder and Holbein , as well as composer Leopold Mozart (father of Amadeus Wolfgang), and

570-400: The basis for his work on and development of the diesel engine. By summer 1893, Diesel had realised that his initial theory was erroneous, leading him to file another patent application for the corrected theory in 1893. Diesel understood thermodynamics and the theoretical and practical constraints on fuel efficiency. He knew that as much as 90% of the energy available in the fuel is wasted in

608-441: The benefit of running more fuel-efficiently than any other internal combustion engines suited for motor vehicles, allowing more heat to be converted to mechanical work. Diesel was interested in using coal dust or vegetable oil as fuel, and in fact, his engine was run on peanut oil. Although these fuels were not better replacements, in 2008 the rise in fuel prices coupled with concerns about remaining petroleum reserves , led to

646-574: The combustion chamber, leading to a higher internal temperature, expanding at a higher rate and placing further pressure over the pistons that rotate the crankshaft towards a quicker rate. Biodiesel often composed of synthesis gas originating from waste cellulose gasification , as well as extraction of lipids from algae , most frequently used by consisting vegetable oils and algae together under methanol transesterification . Numerous firms have developed different techniques in order to achieve such. The first successful diesel engine Motor 250/400

684-490: The first internal combustion engine here, Linde built the first refrigerator, and Messerschmitt created the first mass-produced jet airplane. Today, with its rich heritage, Augsburg and the region are centers for industry, science, art and culture. Augsburg has circa 275,000 inhabitants, is a university city and is the third largest economic- and industrial center in Bavaria . The city of Augsburg and its surrounding rural areas offer attractive business and industry zones and are

722-449: The following week. She discovered 20,000 German marks in cash (US$ 120,000 today) and financial statements indicating that their bank accounts were virtually empty. In a diary Diesel brought with him on the ship, for the date 29 September 1913, a cross was drawn, possibly indicating death. Ten days after he was last seen, the crew of the Dutch pilot boat Coertsen came upon the corpse of

760-524: The headquarters of research institutions and technology concerns. Augsburg is the only German city with its own legal holiday, the Peace of Augsburg, celebrated on August 8 of every year, to commemorate the religious parity declared in Augsburg in 1555. This gives Augsburg more legal holidays than any other region or city in Germany. The district comprises a large area west of the city of Augsburg. 90% are located in

798-410: The more widespread use of vegetable oil and biodiesel . The primary fuel used in Diesel engines is the eponymous diesel fuel , derived from the refinement of crude oil . Diesel is safer to store than gasoline, because its flash point is approximately 79.4 °C (174.9 °F) higher, and it will not explode. In a book titled Diesel Engines for Land and Marine Work , Diesel said that "In 1900

836-916: The next examination date, he gained practical engineering experience at the Sulzer Brothers Machine Works in Winterthur , Switzerland. Diesel graduated in January 1880 with highest academic honours and returned to Paris, where he assisted Linde with the design and construction of a modern refrigeration and ice plant. Diesel became the director of the plant a year afterwards. In 1883, Diesel married Martha Flasche, and continued to work for Linde, gaining numerous patents in both Germany and France. In early 1890, Diesel moved to Berlin with his wife and children, Rudolf Jr, Heddy, and Eugen, to assume management of Linde's corporate research and development department and to join several other corporate boards. Since he

874-592: The occasion of the 100th anniversary of Diesel's birth and the 60th anniversary of the diesel engine development, Yamaoka dedicated the Rudolf Diesel Memorial Garden ( Rudolf-Diesel-Gedächtnishain ) in Wittelsbacher Park in Augsburg , Bavaria, where Diesel had undertaken his early technical education and original engine development. After Diesel's death, his engine underwent much development and became

912-477: The opportunity to test and develop his ideas. Diesel also received support from the Krupp firm. Diesel's design utilised compression ignition as opposed to using spark plugs similar to gas engines , with the ability to be run on biodiesel , if not petroleum -originating fuels. Compression engines are circa 30% more efficient over conventional gas burning engines, being mixed through forced compressed air within

950-652: The playwright Berthold Brecht . Rococo became so prevalent in the city that it became known as “Augsburg style”. After the Thirty Years' War, the decorative arts came to the fore. Gold- and silversmiths as well as copper engraving and lithography flourished. The crafters guilds were very strong and their work was known internationally. At the end of the 18th century, the textile industry began its rise to prominence, followed by machine manufacturing (MAN, Diesel, Messerschmitt). Groundbreaking innovations in industry lent Augsburg international standing. Rudolf Diesel constructed

988-645: The site of current-day Augsburg. The camp soon became the capital of the Roman province Raetia . Augsburg's early development was molded by its 400-year affiliation with the Roman Empire. Critical to its ascent were its military importance in the Roman Empire, as well as its favorable location at the confluence of the Alpine rivers, the Lech and the Wertach, with direct access to the most important Alpine passes. Consequently, Augsburg

1026-413: The strength of iron and steel cylinder heads. One exploded during a test run. He spent many months in a hospital, followed by health and eyesight problems. It was during this year that Diesel began conceptualising the idea of a diesel engine. Ever since attending lectures of von Linde, Diesel worked on designing an internal combustion engine that could approach the maximum theoretical thermal efficiency of

1064-628: The top of his class in 1873, he enrolled at the newly founded Industrial School of Augsburg. Two years later, he received a merit scholarship from the Royal Bavarian Polytechnic of Munich , which he accepted against the wishes of his parents, who wanted him to begin working instead. One of Diesel's professors in Munich was Carl von Linde . Diesel was unable to graduate with his class in July 1879 because he fell ill with typhoid fever . While waiting for

1102-595: The village from the west to the east where they empty into the Schmutter river . The Gailenbacher Mühle ( Gailenbach mill ) lies on the banks of the Schmutter and belongs to Edenbergen as well as Gailenbach, a small hamlet in the southeast of Edenbergen. Edenbergen is the smallest village of the municipality of Gersthofen and amounts only to about 1.5 percent of the town's total population. On 1 July 2009, 304 people lived in Edenbergen, 148 females and 156 males. This corresponds to

1140-639: The war's end, however, Diesel's mother sent 12-year-old Rudolf to Augsburg to live with his aunt and uncle, Barbara and Christoph Barnickel, to become fluent in German and to visit the Königliche Kreis-Gewerbeschule (Royal County Vocational College), where his uncle taught mathematics. He was enrolled at the Technische Hochschule (Tehnical High School). At the age of 14, Diesel wrote a letter to his parents saying that he intended to become an engineer. After finishing his basic education at

1178-503: Was a German inventor and mechanical engineer who invented the Diesel engine , which burns Diesel fuel ; both are named after him. Diesel was born at 38 Rue Notre Dame de Nazareth in Paris, France , in 1858 the second of three children of Elise (née Strobel) and Theodor Diesel. His parents were Bavarian immigrants living in Paris. Theodor Diesel, a bookbinder by trade, left his home town of Augsburg , Bavaria , in 1848. He met his wife,

1216-460: Was established in 1972 by merging the former districts of Augsburg and Schwabmünchen and parts of other adjoining districts. More than twice as old as Nuremberg or Munich , Augsburg was founded in 15 B.C. by the Roman commanders Drusus and Tiberius . Under the orders of their stepfather Emperor Augustus , they enslaved the Celts and Alp-dwellers and founded the military camp Augusta Vindelicorum on

1254-562: Was murdered, given his refusal to grant the German forces the exclusive rights to using his invention; indeed, Diesel had boarded Dresden with the intent of meeting with representatives of the Royal Navy to discuss the possibility of powering British submarines by diesel engine. Another theory is that his apparent death was a ruse staged by the British government to cover his defection to the British cause, and that he then went to Canada, worked for

1292-477: Was never seen alive again. In the morning his cabin was empty and his bed had not been slept in, although his nightshirt was neatly laid out and his watch had been left where it could be seen from the bed. His hat and neatly folded overcoat were discovered beneath the afterdeck railing. Shortly after Diesel's disappearance, his wife Martha opened a bag that her husband had given to her just before his ill-fated voyage, with directions that it should not be opened until

1330-422: Was not allowed to use for his own purposes the patents he developed while an employee of Linde's, he expanded beyond the field of refrigeration. He first worked with steam, his research into thermal efficiency and fuel efficiency leading him to build a steam engine using ammonia vapor . During tests, however, the engine exploded and almost killed him. His research into high-compression cylinder pressures tested

1368-486: Was officially tested in 1897, featuring a 25 horsepower four-stroke , single vertical cylinder compression. Having just revolutionised the engine manufacturing industry, it became an immediate success, with royalties amassing great wealth for Diesel. The engine is currently on display at the German Technical Museum in Munich. Besides Germany, Diesel obtained patents for his design in other countries, including

1406-453: Was situated at the intersection of many important European east-west and north-south connections. Out of these Roman roads emerged the trade routes of the Middle Ages. In the 13th century, Augsburg became a Free Imperial City and remained so for the next 500 years. Augsburg has been a bishopric for over 1250 years. The peak years of growth were reached in the 15th and 16th centuries through

1444-484: Was smaller and weighed less than most contemporary steam engines , not to mention the fact that further fuel sources weren't required. Fuel efficiency was measured 75% above the 10% theoretical efficiency for steam engines. In his engine, fuel was injected at the end of the compression stroke and was ignited by the high temperature resulting from the compression. From 1893 to 1897, Heinrich von Buz, director of Maschinenfabrik Augsburg in Augsburg, provided Rudolf Diesel
