Praga Lady
The mid-sized Praga Lady car was built in eight series and replaced the Piccolo 307. First introduced in 1935, it continued to be built until 1947. It was most common as a four-door saloon but also available with two doors or as a convertible and pick-up truck. A variety of ambulance versions were also built. The first series (1935-1937) was also available as a two-seat roadster, bodied by Oldřich Uhlík in Prague. It reached a maximum speed of and consumed fuel at a rate of . It was based on the Piccolo 307. Bodywork consisted of a wooden frame covered by sheet metal. The Lady received the larger Super Piccolo engine after the first 150 cars had been built (often called "Lady 307" in retrospect), increasing the displacement from the original Piccolo 307 engine's to . Power went from to . This engine has an aluminium head of Ricardo's "turbulent head" design and Bohnalite pistons. Maximum speed and fuel consumption increased correspondingly, to and . The bodywork consisted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Praga (company)
Praga is a manufacturing company based in Prague, Czech Republic. The company produced automobiles, karts and planes. The Praga V3S 5-ton truck was used by the Czechoslovak Army for more than half a century. History Praga was founded in 1907 to build motor cars as a venture between entrepreneur František Ringhoffer and the company ''1. českomoravská továrna na stroje'' ("First Bohemian-Moravian Machine Works", later a founding part of the ČKD factories). Ringhoffer only stayed for one year and in 1909 the trade name ''Praga'' ("Prague" in Latin) was adopted. One of its early models was built under licence from the Italian company of Isotta Fraschini. Besides building its own vehicles Praga later also supplied engines and gearboxes for other vehicles, like aircraft and tanks. In 1929 Praga merged with ČKD, one of Czechoslovakia's largest engineering companies. In 1929 ČKD's BD motorcycle was re-branded under the Praga marque. This was an advanced four-stroke single- ...

Flathead Engine
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inline-four Engine
A straight-four engine (also called an inline-four) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The vast majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power stroke occu ...

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom, and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission (mechanics), transmission system, where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission; common types of automatic transmissions are the Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic transmission (AT), and the continuously variable transmissio ...

Praga Piccolo
The Praga Super Piccolo was a car produced by Praga in Czechoslovakia between 1934 and 1936. Design Launched at the 1934 Prague Motor Show, the Super Piccolo was designed as a mid-range replacement to the smaller Piccolo which would suit people who did not want the larger Alfa. Of conventional construction, with a rectangular frame chassis with X-shape stiffener, the car was initially produced as a four-door sedan only. This was joined by a small number of two-door Sidomka and Sodomkovy aerodynamic convertibles, but the biggest upheaval came at the 1935 Berlin Motor Show The Berlin Motor Show originally started in 1897 in the German capital Berlin as the home of the International Motor Show (''Internationale Automobil-Ausstellung'', IAA) and ran until 1939. From 1951 the IAA eventually became established in Frankf ... where Praga launched a distinctive aerodynamic sedan. The new model had a more curvilinear shape and covered front and rear wheels.

Nelson Bohnalite
Nelson-Bohnalite was the name of a piston developed by Adolph Lincoln Nelson in the 1930s and 1940s. The pistons were licensed to Bohn Aluminum and sold to all the major auto manufacturers at the time. These were some of the first pistons to use an aluminum body with a steel strut, allowing for the weight of aluminum and the strength of steel where the piston moves on the piston rod. Many then existing brands of autos used this type of piston in the mid-1930s: Auburn, Graham, Hupmobile Hupmobile was an automobile built from 1909 through 1939 by the Hupp Motor Car Company of Detroit. The prototype was developed in 1908. History Founding In 1909, Bobby Hupp co-founded Hupp Motor Car Company, with Charles Hastings, for ..., Nash, Packard, Pierce-Arrow and Studebaker.

World War II
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] |
Cars Of The Czech Republic
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. These i ...

Praga Vehicles
Praga is a district of Warsaw, Poland. It is on the east bank of the river Vistula. First mentioned in 1432, until 1791 it formed a separate town with its own city charter. History The historical Praga was a small settlement located at the eastern bank of the Vistula river, directly opposite the towns of Old Warsaw and Mariensztat, both being parts of Warsaw now. First mentioned in 1432, it derived its name from the Polish verb ''prażyć'', meaning ''to burn'' or ''to roast'', as it occupied a forested area that was burnt out to make place for the village. Separated from Warsaw by a wide river, it developed independently of the nearby city, and on 10 February 1648 king Władysław IV of Poland granted Praga with a city charter. However, as it was mostly a suburb and most buildings were wooden, the town was repeatedly destroyed by fires, floods and foreign armies. Currently the only surviving historical monument from that epoch is the Church of Our Lady of Loreto. Altho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
