Steam Tricycles
A steam tricycle is a steam-driven three-wheeled vehicle. History In the early days of motorised vehicle development, a number of experimenters built steam-powered vehicles with three wheels. The first steam tricycle – and probably the first true self-propelled land vehicle – was Nicolas-Joseph Cugnot's 1769 ''Fardier à vapeur'' (steam dray), a three-wheeled machine with a top speed of around 3 km/h (2 mph) originally designed for hauling artillery. Failing to meet the army's design criteria, no further development was undertaken. The Long steam tricycle appears to be one of the earliest preserved examples, built by George A. Long around 1880 and patented some time around 1882; an example is on display at the Smithsonian Institution. In 1881 the Parkyns-Bateman steam tricycle was demonstrated in England. It used a petroleum-fired steam boiler (making it the first petroleum-powered vehicle), driving a double-acting two cylinder steam engine on the chassis of a C ...

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 to ...

Steam Road Vehicles
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. Types ...

List Of Motorized Trikes
List of motorized trikes is a list of motorized tricycles also called trikes, and sometimes considered cars. There are three typical configurations: motorized bicycle with sidecar; two wheels in the rear, one in the front (aka trike); and two in front, one in the rear (aka reverse trike). However, language and definitions vary. One of the most successful trikes of its day was the De Dion-Bouton tricycle; from 1897 until the start of the 20th century about 15,000 licensed copies were sold, with De Dion Bouton usually supplying the engines, and it was overall the most popular motor vehicle in Europe. Trikes have caused tautological confusion and simply defied typical two and four-wheel classifications, especially in the 21st century. Regardless, many popular motorcycles and/or automobiles had three wheels.

Traction Engine
A traction engine is a steam engine, steam-powered tractor used to move heavy loads on roads, plough ground or to provide power at a chosen location. The name derives from the Latin ''tractus'', meaning 'drawn', since the prime function of any traction engine is to draw a load behind it. They are sometimes called road locomotives to distinguish them from railway steam locomotive, locomotives – that is, steam engines that run on rails. Traction engines tend to be large, robust and powerful, but also heavy, slow, and difficult to manoeuvre. Nevertheless, they revolutionized agriculture and road haulage at a time when the only alternative Prime mover (tractor unit), prime mover was the draught horse. They became popular in industrialised countries from around 1850, when the first self-propelled portable steam engines for agricultural use were developed. Production continued well into the early part of the 20th century, when competition from internal combustion engine-powered ...

Steam Tractor
:''This article refers to the steam-powered agricultural tractor; for other types of steam tractor, see: Traction engine'' A steam tractor is a vehicle powered by a steam engine which is used for pulling. In North America, the term ''steam tractor'' usually refers to a type of agricultural tractor powered by a steam engine, used extensively in the late 19th and early 20th centuries. In Great Britain, the term ''steam tractor'' is more usually applied to the smallest models of traction engine - typically those weighing seven tons or less - used for hauling small loads on public roads. Although known as ''light steam tractors'', these engines are generally just smaller versions of the ' road locomotive'. This article concentrates on the steam-powered agricultural vehicles intended for the direct-pulling of ploughs and other implements (as opposed to cable-hauling). Development (Great Britain) Owing to differences in soil conditions, the development of steam-powered agricult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steamroller
A steamroller (or steam roller) is a form of road roller – a type of heavy construction machinery used for leveling surfaces, such as roads or airfields – that is powered by a steam engine. The leveling/flattening action is achieved through a combination of the size and weight of the vehicle and the ''rolls'': the smooth wheels and the large cylinder or drum fitted in place of treaded road wheels. The majority of steam rollers are outwardly similar to traction engines as many traction engine manufacturers later produced rollers based on their existing designs, and the patents owned by certain roller manufacturers tended to influence the general arrangements used by others. The key difference between the two vehicles is that on a roller the main roll replaces the front wheels and axle that would be fitted to a traction engine, and the driving wheels are smooth-tired. The word ''steamroller'' frequently refers to road rollers in general, regardless of the method of propulsion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Car
A steam car is a car (automobile) propelled by a steam engine. A steam engine is an external combustion engine (ECE) in which the fuel is combusted outside of the engine, unlike an internal combustion engine (ICE) in which fuel is combusted inside the engine. ECEs have a lower thermal efficiency, but carbon monoxide production is more readily regulated. Steam-powered automobiles were popular with early buyers. Steam was safe, reliable, and familiar. People had decades of experience with it in trains and boats, and even in experimental road vehicles. However, early steam cars required constant care and attention—and up to 30 minutes to start. Automated quick-firing boilers solved these problems, but not before more efficient gasoline engines dominated the market and made steam cars obsolete. The first experimental steam-powered cars were built in the 18th and 19th centuries, but it was not until after Richard Trevithick had developed the use of high-pressure steam around 1800 ...

Internal Combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons ( piston engine), turbine blades (gas turbine), a rotor (Wankel engine), or a nozzle ( jet engine). This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine was more important. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860, and the first modern internal combustion engine, known ...
