Scania-Vabis 335
The Scania-Vabis 335/345/355 was a series of heavy duty trucks produced by Swedish automaker Scania-Vabis between 1931 and 1944. Scania-Vabis 335 In 1931 Scania-Vabis presented a larger version of its standard truck, called the 335. The truck had a payload capacity of 4 to 5 tonnes and was sold with a six-cylinder engine in petrol or Hesselman version. In 1936 the truck was modernized with a more streamlined front with a slightly sloping radiator cover. More importantly the engine and cab was moved forward so that the engine was mounted above the front axle. This meant increased payload capacity with a longer loading platform and a better distribution of axle loads. From 1936 onwards the truck was offered with Scania-Vabis’ first pre-chamber diesel engine. Sales to private customers ceased at the outbreak of the Second World War. All production went instead to the Swedish Armed Forces and other public institutions. Most engines were converted to run on wood gas. The lo ...

Scania-Vabis
Scania AB is a major Swedish manufacturer headquartered in Södertälje, focusing on commercial vehicles—specifically heavy lorries, trucks and buses. It also manufactures diesel engines for heavy vehicles as well as marine and general industrial applications. Scania was formed in 1911 through the merger of Södertälje-based Vabis and Malmö-based Maskinfabriks-aktiebolaget Scania. Since 1912, the company has been re-located again to Södertälje after the merger. Today, Scania has production facilities in Sweden, France, the Netherlands, Thailand, China, India, Argentina, Brazil, Poland, Russia and Finland. In addition, there are assembly plants in ten countries in Africa, Asia and Europe. Scania's sales and service organisation and finance companies are worldwide. In 2012, the company employed approximately 42,100 people around the world. Scania was listed on the NASDAQ OMX Stockholm stock exchange from 1996 to 2014. The company is a subsidiary of Traton, part of the Vo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wood Gas
Wood gas is a fuel gas that can be used for furnaces, stoves, and vehicles. During the production process, biomass or related carbon-containing materials are gasified within the oxygen-limited environment of a wood gas generator to produce a combustible mixture. In some gasifiers this process is preceded by pyrolysis, where the biomass or coal is first converted to char, releasing methane and tar rich in polycyclic aromatic hydrocarbons. In stark contrast with synthesis gas, which is almost pure H2/CO mixture, wood gas ''also'' contains a variety of organic compound ("distillates") that require scrubbing for use in other applications. Depending on the kind of biomass, a variety of contaminants are produced that will condense out as the gas cools. When producer gas is used to power cars and boats or distributed to remote locations it is necessary to scrub the gas to remove the materials that can condense and clog carburetors and gas lines. Anthracite and coke are preferred for aut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straight-eight Engine
The straight-eight engine (also referred to as an inline-eight engine; abbreviated I8 or L8) is a piston engine with eight cylinders arranged in a straight line along the crankshaft. The number of cylinders and perfect primary and secondary engine balance resulted in smooth running, however there are several downsides relating to the significant length of the engine. Straight-eight engines were popular in luxury cars and racing cars in the 1920s to 1940s. During the 1950s, straight-eight engines were largely replaced by the more compact V8 engine design. Design A straight-eight can achieve perfect primary balance and secondary balance if an appropriate firing order is used. Like most other engines, torsional vibration of the crankshaft requires that a harmonic damper is installed on the crankshaft. at the accessory end of the crankshaft. As per other engines with 8 cylinders, the power delivery is smoother than engines with fewer cylinders. In the early 20th century, these sm ...

Conventional Truck
A truck or lorry is a motor vehicle designed to transport cargo, carry specialized payloads, or perform other utilitarian work. Trucks vary greatly in size, power, and configuration, but the vast majority feature body-on-frame construction, with a cabin that is independent of the payload portion of the vehicle. Smaller varieties may be mechanically similar to some automobiles. Commercial trucks can be very large and powerful and may be configured to be mounted with specialized equipment, such as in the case of refuse trucks, fire trucks, concrete mixers, and suction excavators. In American English, a commercial vehicle without a trailer or other articulation is formally a "straight truck" while one designed specifically to pull a trailer is not a truck but a "tractor". The majority of trucks currently in use are still powered by diesel engines, although small- to medium-size trucks with gasoline engines exist in the US, Canada, and Mexico. The market-share of electrically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trailing Axle
On a steam locomotive, a trailing wheel or trailing axle is generally an unpowered wheel or axle ( wheelset) located behind the driving wheels. The axle of the trailing wheels is usually located in a trailing truck. On some large locomotives, a booster engine was mounted on the trailing truck to provide extra tractive effort when starting a heavy train and at low speeds on gradients. Trailing wheels were used in some early locomotives but fell out of favor for a time during the latter 19th century. As demand for more powerful locomotives increased, trailing wheels began to be used to support the crew cab and rear firebox area. Trailing wheels first appeared on American locomotives between 1890 and 1895, but their axle worked in rigid pedestals. It enabled boilers to be lowered, since the top of the main frames was dropped down behind the driving wheels and under the firebox. The firebox could also be longer and wider, increasing the heating surface area and steam generatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scania-Vabis L75
The Scania-Vabis L75/L76 was a series of heavy duty trucks produced by Sweden, Swedish automaker Scania-Vabis between 1958 and 1968. Scania-Vabis L75 In the spring of 1958, Scania-Vabis introduced a new generation of trucks, with newly designed six-cylinder engines, stronger chassis components and a new, more spacious and comfortable cab. The cab would be used for all conventional trucks until 1980. The largest model, called L75, had a ten-litre engine. The truck was also offered with a trailing axle. This version was called the LS75, with an “S” for "support axle". For real heavy duty work Scania-Vabis offered a version with tandem drive rear axles. It was called LT75, with “T” for "tandem". The L75 series trucks came with Air brake (road vehicle), air brakes, but power steering was still an option. From 1961 the truck was offered with a turbo-diesel. Scania-Vabis L76 In early 1963 the improved L76/LS76/LT76 series was introduced, with an eleven-litre engine and dual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forward Control
Cab-over, also known as cab over engine (COE), cab forward (U.S.), flat nose (Canada), or forward control (UK), is a body style of truck, bus, or van that has a vertical front, "flat face" or a semi-hood, with the cab of the truck sitting above (or forward of) the front axle. This contrasts with a conventional truck where the engine is mounted in front of the driver. This truck configuration is currently common among European and Asian truck manufacturers. European regulations set restrictions for both the total length and the length of the load area, which allow a cab length of in combination with the maximum load area length. This allows a sleeper cab with a narrow bunk, and would allow a bonneted (hooded) day cab. Nonetheless, no manufacturer in Europe produces such day cabs with bonnets. The last manufacturer of a conventional in Europe, Scania, stopped production in 2005. (The reason was a decline to less than 1000 units worldwide, with European sales declining by 50% ...

Swedish Armed Forces
The Swedish Armed Forces ( sv, Försvarsmakten, "the Defense Force") is the government agency that forms the armed forces of Sweden, tasked with the defense of the country as well as with promoting Sweden's wider interests, supporting international peacekeeping, and providing humanitarian aid. It consists of the Swedish Army, the Swedish Air Force and the Swedish Navy, as well as a military reserve force, the Home Guard. Since 1994, all Swedish military branches are organized within a single unified government agency, headed by the Supreme Commander, even though the individual services maintain their distinct identities. The Swedish Armed Forces is made up of 23,600 active personnel, 11,200 military reserves, 24,000 Home Guard and 5,200 conscripts (set to increase to 8,000 conscripts by 2024) as of 2022. Units of the Swedish Armed Forces are currently on deployment in several international operations either actively or as military observers, including Afghanistan as part o ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
