Grofri
Grofri was a brand of cars manufactured in Austria from 1921 to 1931 (1924 to 1927 under licence from the French Amilcar). SV 903 cc or 1074 cc four-cylinder engines were used in these sporting cyclecars. Racing versions were also made, some of them with Roots A root is the part of a plant, generally underground, that anchors the plant body, and absorbs and stores water and nutrients.

The Gross & Friedmann house in Altzerdorf near Vienna manufactured these vehicles. The racing cars were successful, particularly in hillclimbs. Successful race car driver Max Hoffmann (later known for introducing the United States to imports such as the Volkswagen, the Porsche 356, and the BMW) was selected as Grofri's factory driver. He continued racing until his final event, a 1936 hillclimb. Famous opera singer Käthe Rantzau also successfully ...

Amilcar
The Amilcar was a French automobile manufactured from 1921 to 1940. History Foundation and location Amilcar was founded in July 1921 by Joseph Lamy and Emile Akar. The name "Amilcar" was an imperfect anagram of the partners' names. The business was established at 34 rue du Chemin-Vert in the 11th arrondissement of Paris. However, Amilcar quickly outgrew their restricted city-centre premises, and during the middle part of 1924 the company relocated to Saint-Denis on the northern edge of the city. Early years The original Amilcar was a small cyclecar. Designed by Jules Salomon and Edmond Moyet, it bore a striking resemblance to the pre-war Le Zèbre. The vehicle was first exhibited at the Paris Motor Show in October 1921. The business was a leading beneficiary of a cyclecar boom, prompted by a government initiative which held out the promise of a reduced rate of annual car tax, fixed at 100 francs per year, for powered vehicles weighing no more than 350 kg ( ...

Cyclecar
A cyclecar was a type of small, lightweight and inexpensive car manufactured in Europe and the United States between 1910 and the early 1920s. The purpose of cyclecars was to fill a gap in the market between the motorcycle and the car. A key characteristic was that it could only accommodate two passengers sitting tandem style or passenger behind the driver. The demise of cyclecars was due to larger cars – such as the Citroën Type C, Austin 7 and Morris Cowley – becoming more affordable. Small, inexpensive vehicles reappeared after World War II, and were known as microcars. Characteristics Cyclecars were propelled by engines with a single cylinder or V-twin configuration (or occasionally a four cylinder engine), which were often air-cooled. Sometimes motorcycle engines were used, in which case the motorcycle gearbox was also used. All cyclecars were required to have clutches and variable gears. This requirement could be fulfilled by even the simplest devices ...

Austria
Austria, , bar, Östareich officially the Republic of Austria, is a country in the southern part of Central Europe, lying in the Eastern Alps. It is a federation of nine states, one of which is the capital, Vienna, the most populous city and state. A landlocked country, Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has a population of 9 million. Austria emerged from the remnants of the Eastern and Hungarian March at the end of the first millennium. Originally a margraviate of Bavaria, it developed into a duchy of the Holy Roman Empire in 1156 and was later made an archduchy in 1453. In the 16th century, Vienna began serving as the empire's administrative capital and Austria thus became the heartland of the Habsburg monarchy. After the dissolution of the H ...

Sidevalve
A flathead engine, also known as a sidevalve engine''American Rodder'', 6/94, pp.45 & 93. or valve-in-block engine is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve engine. Flatheads were widely used internationally by automobile manufacturers from the late 1890s until the mid-1950s but were replaced by more efficient overhead valve and overhead camshaft engines. They are currently experiencing a revival in low-revving aero-engines such as the D-Motor. The side-valve design The valve gear comprises a camshaft sited low in the cylinder block which operates the poppet valves via tappets and short pushrods (or sometimes with no pushrods at all). The flathead system obviates the need for further valvetrain components such as lengthy pushrods, rocker arms, overhead valves or overhead camshafts. The sidevalves are typically adjacent, sited on one side of the cylinder(s), though some ...

Roots Type Supercharger
The Roots-type blower is a positive displacement lobe pump which operates by pumping a fluid with a pair of meshing lobes resembling a set of stretched gears. Fluid is trapped in pockets surrounding the lobes and carried from the intake side to the exhaust. The most common application of the Roots-type blower has been the induction device on two-stroke diesel engines, such as those produced by Detroit Diesel and Electro-Motive Diesel. Roots-type blowers are also used to supercharge four-stroke Otto cycle engines, with the blower being driven from the engine's crankshaft via a toothed or V-belt, a roller chain or a gear train. The Roots-type blower is named after American inventors and brothers Philander and Francis Marion Roots, founders of the Roots Blower Company of Connersville, Indiana USA, who patented the basic design in 1860 as an air pump for use in blast furnaces and other industrial applications. In 1900, Gottlieb Daimler included a Roots-style blower ...

Supercharger
In an internal combustion engine, a supercharger compresses the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a supercharger is a form of forced induction that is mechanically powered (usually by a belt from the engine's crankshaft), as opposed to a turbocharger, which is powered by the kinetic energy of the exhaust gasses. However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. The first supercharged engine was built in 1878, with usage in aircraft engines beginning in the 1910s and usage in car engines beginning in the 1920s. In piston engines used by aircraft, supercharging was often used to compensate for the lower air density at high altitudes. Supercharging is less commonly used in the 21st century, as manufacturers have shifted to turbochargers to reduce fuel consumption and/or increase power outputs. ...

Car Manufacturers Of Austria
A car or automobile is a motor vehicle with wheels. Most definitions of ''cars'' say that they run primarily on roads, seat one to eight people, have four wheels, and mainly transport people instead of goods. The year 1886 is regarded as the birth year of the car, when German inventor Carl Benz patented his Benz Patent-Motorwagen. Cars became widely available during the 20th century. One of the first cars affordable by the masses was the 1908 Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the US, where they replaced animal-drawn carriages and carts. In Europe and other parts of the world, demand for automobiles did not increase until after World War II. The car is considered an essential part of the developed economy. Cars have controls for driving, parking, passenger comfort, and a variety of lights. Over the decades, additional features and controls have been added to vehicles, making them progressively more complex ...

Vintage Vehicles
Vintage, in winemaking, is the process of picking grapes and creating the finished product—wine (see Harvest (wine)). A vintage wine is one made from grapes that were all, or primarily, grown and harvested in a single specified year. In certain wines, it can denote quality, as in Port wine, where Port houses make and declare vintage Port in their best years. From this tradition, a common, though not strictly correct, usage applies the term to any wine that is perceived to be particularly old or of a particularly high quality. Most countries allow a vintage wine to include a portion of wine that is not from the year denoted on the label. In Chile and South Africa, the requirement is 75% same-year content for vintage-dated wine. In Australia, New Zealand, and the member states of the European Union, the requirement is 85%. In the United States, the requirement is 85%, unless the wine is designated with an AVA, (e.g., Napa Valley), in which case it is 95%. Technically, the 85% ...
