Léon Serpollet
Léon Serpollet (4 October 1858 – 1 February 1907) was a French engineer and developer of flash steam boilers and steam automobiles. Léon Serpollet was born in Culoz, in the Ain department of France in 1859, son of the carpenter Auguste Serpollet. He went into the family business with his brother Henri (1848–1915) producing circular saws and wood working machines. It was when seeking to power their workshops that Henri came up with the idea of flash steam generation, with a patent applied for on 25 October 1879. Leon went to Paris to study engineering at the Conservatoire national des arts et métiers, and at the same time he continued to develop the flash steam concept with his brother by post. In 1886 the two brothers arrived at their best design of flash steam boiler, and then shortly afterwards they went into business building flash steam boilers, initially small scale to power lighting systems and pumps, but soon to power tricycles and steam boats, and eventually ...

Jules-Albert De Dion
Marquis Jules Félix Philippe Albert de Dion de Wandonne (; 9 March 185619 August 1946) was a French pioneer of the automobile industry. He invented a steam-powered car and used it to win the world's first auto race, but his vehicle was adjudged to be against the rules. He was a co-founder of De Dion-Bouton, the world's largest automobile manufacturer for a time, as well as the French sports newspaper ''L'Équipe''. His life Dion was the heir of a leading French noble family, in 1901 succeeding his father Louis Albert William Joseph de Dion de Wandonne as Count and later Marquis. A "notorious duellist", he also had a passion for mechanics. He had already built a model steam engine when, in 1881, he saw one in a store window and asked about building another. The engineers, Georges Bouton and his brother-in-law, Charles Trépardoux, had a shop in Léon where they made scientific toys. Needing money for Trépardoux's long-time dream of a steam car, they acceded to De Di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
19th-century French Inventors
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It was characterized by vast social upheaval. Slavery was Abolitionism, abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems an ...

History Of Steam Road Vehicles
The history of steam road vehicles comprises the development of vehicles powered by a steam engine for use on land and independent of rails, whether for conventional road use, such as the steam car and steam waggon, or for agricultural or heavy haulage work, such as the traction engine. The first experimental vehicles were built in the 18th and 19th century, but it was not until after Richard Trevithick had developed the use of high-pressure steam, around 1800, that mobile steam engines became a practical proposition. The first half of the 19th century saw great progress in steam vehicle design, and by the 1850s it was viable to produce them on a commercial basis. This progress was dampened by legislation which limited or prohibited the use of steam-powered vehicles on roads. Nevertheless, the 1880s to the 1920s saw continuing improvements in vehicle technology and manufacturing techniques, and steam road vehicles were developed for many applications. In the 20th century, the ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Bus
A steam bus is a bus powered by a steam engine. Early steam-powered vehicles designed for carrying passengers were more usually known as steam carriages, although this term was sometimes used to describe other early experimental vehicles too. History 1830-1895 Regular intercity bus services by steam-powered buses were pioneered in England in the 1830s by associates of Goldsworthy Gurney, Sir Goldsworthy Gurney and by Walter Hancock among others, running reliable services over road conditions which were too hazardous for horse-drawn transportation. Steam carriages were much less likely to overturn, and did not "run away with" the customer as horses sometimes did. They travelled faster than horse-drawn carriages ( over and an average of over longer distances). They could run at a half to a third of the cost of horse-drawn carriages. Their brakes did not lock and drag like horse-drawn transport (a phenomenon that increased damage to roads). According to engineers, steam carri ...

Variable Valve Timing
Variable valve timing (VVT) is the process of altering the timing of a Poppet valve, valve lift event in an internal combustion engine, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems. There are many ways in which this can be achieved, ranging from mechanical devices to electro-hydraulic and camless systems. Increasingly strict emissions regulations are causing many automotive manufacturers to use VVT systems. Two-stroke cycle, Two-stroke engines use a Two-stroke power valve system, power valve system to get similar results to VVT. Background theory The valves within an internal combustion engine are used to control the flow of the intake and exhaust gases into and out of the combustion chamber. The timing, duration and lift of these valve events has a significant impact on engine performance. Without variable valve timing (variable valve lift), the valve timing is the same for all ...

Cutoff (steam Engine)
In a steam engine, cutoff is the point in the piston stroke at which the inlet valve is closed. On a steam locomotive, the cutoff is controlled by the reversing gear. The point at which the inlet valve closes and stops the entry of steam into the cylinder from the boiler plays a crucial role in the control of a steam engine. Once the valve has closed, steam trapped in the cylinder expands adiabatically. The steam pressure drops as it expands. A late cutoff delivers full steam pressure to move the piston through its entire stroke, for maximum start-up forces. But, since there will still be unexploited pressure in the cylinder at the end of the stroke, this is achieved at the expense of engine efficiency. In this situation the steam will still have considerable pressure remaining when it is exhausted resulting in the characteristic “chuff chuff” sound of a steam engine. An early cutoff has greater thermodynamic efficiency but results in a lower mean effective pressure so les ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poppet Valve
A poppet valve (also sometimes called mushroom valve) is a valve typically used to control the timing and quantity of petrol (gas) or vapour flow into or out of an engine, but with many other applications. It consists of a hole or open-ended chamber, usually round or oval in cross-section, and a plug, usually a disk shape on the end of a shaft known as a valve stem. The working end of this plug, the valve face, is typically ground at a 45° bevel to seal against a corresponding valve seat ground into the rim of the chamber being sealed. The shaft travels through a valve guide to maintain its alignment. A pressure differential on either side of the valve can assist or impair its performance. In exhaust applications higher pressure against the valve helps to seal it, and in intake applications lower pressure helps open it. Etymology The word poppet shares etymology with "puppet": it is from the Middle English ''popet'' ("youth" or "doll"), from Middle French ''poupette'', whic ...

Armand Peugeot
Armand Peugeot (; 18 February 1849 – 4 February 1915) was a French industrialist, pioneer of the automobile industry and the man who transformed Peugeot into a manufacturer of bicycles and, later, of automobiles. He was accepted into the Automotive Hall of Fame in 1999. Family Born in 1849 into a Protestant family at Herimoncourt, in eastern France, Armand Peugeot was the son of Emile Peugeot and grandson of Jean-Pierre Peugeot. The family had a metal working business, producing a range of practical goods such as springs, saws, spectacle frames and coffee grinders. In 1872, he married Sophie Leonie Fallot (1852–1930) and they had five children, but their only son, Raymond, died in 1896. Armand Peugeot died on 2 January 1915 in Neuilly-sur-Seine, near Paris.
