Snowmobile
A snowmobile, also known as a snowmachine (chiefly Alaskan), motor sled (chiefly Canadian), motor sledge, skimobile, snow scooter, or simply a sled is a motorized vehicle designed for winter travel and recreation on snow. Their engines normally drive a continuous track at the rear, while skis at the front provide directional control. The earliest snowmobiles were powered by readily available industrial four-stroke, air-cooled engines. These would quickly be replaced by lighter and more powerful two-stroke gasoline internal combustion engines and since the mid-2000s four-stroke engines had re-entered the market. The challenges of cross-country transportation in the winter led to the invention of an all-terrain vehicle specifically designed for travel across deep snow where other vehicles foundered. , the snowmobile market has been shared between the four large North American makers (Bombardier Recreational Products (BRP), Arctic Cat, Yamaha, and Polaris) and some specialized m ...

Snowmobile Skipping
Snowmobile skipping, snowmobile watercross, snowmobile skimming, water skipping or puddle jumping is a sport and/or exhibition where snowmobile racers Hydroplaning (tires), hydroplane their sleds across lakes or rivers. Basics Snowmobile watercross consists of crossing water while riding a snowmobile, which is possible because snowmobiles have wide tracks for traction and flotation in the snow. If one hits the water at an adequate speed (5 mph per 150 lb or km/h per 100 kg of weight) and keeps the sled's throttle open, the track keeps the snowmobile on the surface of the water without sinking. If the rider backs out of the throttle or the sled bogs or floods out, the sled will sink. A sunk sled is able to be revived by cleaning water out of the carburetor, exhaust, spark plugs, and replacing the fuel. The front of the sled is pitched upwards as riders commonly do in deep mountain powder snow. History The Grantsburg, Wisconsin first annual World Championship Sn ...

Off-road
Off-roading is the act of driving or riding in a vehicle on unpaved surfaces such as sand, dirt, gravel, riverbeds, mud, snow, rocks, or other natural terrain. Off-roading ranges from casual drives with regular vehicles to competitive events with customized vehicles and skilled drivers. Off-road vehicle Off-road vehicles are either capable of or specifically developed for off-road driving. These vehicles often have features designed specifically for use in off-road conditions such as suspension lifts, off-road tires, skid plates, snorkels, roll cages, or strengthened drivetrains. Types of recreational off-roading Dune bashing Dune bashing is a specific form of off-roading performed on sand dunes. Dune Buggies, Sport-utility vehicles, and ATVs are often used. Vehicles driven on sand dunes are often equipped with a roll cage for safety in the case of an overturn. The tire pressure is often reduced to gain more traction by increasing the footprint of the tire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caterpillar Track
Continuous track or tracked treads are a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tyres on an equivalent vehicle, enabling continuous tracked vehicles to traverse soft ground with less likelihood of becoming stuck due to sinking. Modern continuous tracks can be made with soft belts of synthetic rubber, reinforced with steel wires, in the case of lighter agricultural machinery. The more common classical type is a solid chain track made of steel plates (with or without rubber pads), also called caterpillar tread or tank tread, which is preferred for robust and heavy construction vehicles and military vehicles. The prominent treads of the metal plates are both hard-wearing and damage resistant, especially in comparison to rubber tyres. The aggressive treads of the t ...

Igor Sikorsky
Igor Ivanovich Sikorsky, (25 May 1889 – 26 October 1972) was a Russian-American aviation pioneer in both helicopters and fixed-wing aircraft. His first success came with the Sikorsky S-2, the second aircraft of his design and construction. His fifth airplane, the Sikorsky S-5, S-5, won him national recognition and Fédération Aéronautique Internationale, F.A.I. pilot's license number 64. His Sikorsky S-6, S-6-A received the highest award at the 1912 Moscow Aviation Exhibition, and in the fall of that year the aircraft won first prize for its young designer, builder and pilot in the military competition at Saint Petersburg. In 1913, the Sikorsky-designed Sikorsky Russky Vityaz, ''Russky Vityaz'' (S-21) became the first successful four-engine aircraft to take flight. He also designed and built the Sikorsky Ilya Muromets, ''Ilya Muromets'' (S-22 – S-27) family of four-engine aircraft, an airliner which he redesigned to be the world's first four-engine bomber when World ...

Kégresse Track
A Kégresse track is a kind of rubber or canvas continuous track which uses a flexible belt rather than interlocking metal segments. It can be fitted to a conventional car or truck to turn it into a half-track, suitable for use over rough or soft ground. Conventional front wheels and steering are used, although skis may also be fitted. A snowmobile is a smaller ski-only type. The mechanism incorporates an articulated bogie, fitted to the rear of the vehicle with a large drive wheel at one end, a large unpowered idler wheel at the other, and several small idler-wheel#idler pulley, guide wheels in between, over which run a reinforced flexible belt. The belt is fitted with metal or rubber treads to grip the ground. History Russia Adolphe Kégresse designed the original system whilst working for Tsar Nicholas II of Russia as a chauffeur and as the head of the royal garage between 1906 and 1917. He applied it to several cars including a Russo-Balt and a 12-cylinder Packard. After ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (reciprocating engine, piston engine), turbine blades (gas turbine), a Wankel engine, rotor (Wankel engine), or a propulsive nozzle, nozzle (jet engine). This force moves the component over a distance. This process transforms chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. The first commercially successful internal combustion engines were invented in the mid-19th century. The first modern internal combustion engine, the Otto engine, was designed in 1876 by the German engineer Nicolaus ... [...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 Thermodynamic power cycle, power cycle with two strokes of the piston, one up and one down, in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle. During the stroke from bottom dead center to top dead center, the end of the exhaust/intake (or Scavenging (automotive), scavenging) is completed along with the compression of the mixture. The second stroke encompasses the combustion of the mixture, the expansion of the burnt mixture and, near bottom dead center, the beginning of the scavenging flows. Two-stroke engines often have a higher power-to-weight ratio than a four-stroke engine, since their power stroke occurs twice as often. Two-stroke engines can also have fewer moving parts, and thus be cheaper to manufacture and weigh less. In countries and regions with stringe ...
