Tatra 75
The Tatra 75 is a Czechoslovak mid-size car that Tatra introduced in 1933 as the successor to the Tatra 54. The front-mounted 1,688 cc air-cooled OHV air-cooled boxer engine produces . This gives a top speed of and fuel consumption of 12 or 13 litres per 100 km. Attention was paid to weight reduction, with light alloy used for the cylinder head castings. In common with other Tatras of this time, the 75 had four-speed transmission and rear-wheel drive. The car was offered with a range of bodies including two- and four-door sedans and convertibles and a six-seat limousine with a longer wheelbase. In its nine-year production run 4,501 Tatra 75s were built. After the 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.

Tatra (company)
Tatra is a Czech vehicle manufacturer from Kopřivnice. It is owned by the ''Tatra Trucks'' company, and it is the third oldest company in the world producing cars with an unbroken history. The company was founded in 1850 as ''Ignatz Schustala & Cie'', in 1890 renamed in German ''Nesselsdorfer Wagenbau-Fabriksgesellschaft'' when it became a wagon and carriage manufacturer. In 1897, Tatra produced the first motor car in central Europe, the Präsident automobile. In 1918, it changed its name to ''Kopřivnická vozovka a.s.'', and in 1919 it changed from the Nesselsdorfer marque to the ''Tatra'' badge, named after the nearby Tatra Mountains on the Czechoslovak-Polish border (now on the Polish- Slovak border). During World War II Tatra was instrumental in the production of trucks and tank engines for the German war effort. Production of passenger cars ceased in 1999, but the company still produces a range of primarily all-wheel-drive trucks, from 4×4 to 18×18. The brand is also ...

Tatra 54
The Tatra 54 is an automobile launched by Tatra in 1931. An economy version of the Tatra 52, it was replaced in 1933 by the Tatra 75. The car was powered by an ohv air-cooled four-cylinder boxer motor of 1465 cc, positioned at the front, and giving a claimed output of . Power was delivered to the front wheels via a four-speed gear-box. The Tatra 54 featured a central "backbone chassis" a hallmark of Design Chief Ledwinka: the front axle was supported by a transverse leaf spring while a second transverse leaf spring supported the swing rear axle. Various four- and six-seater saloon bodies were available with two or four doors. During its three-year production run, 1510 Tatra 54s were built. Differences between Tatra 30, Tatra 54 and Tatra 54/30 In the 1930s there was rather gradual evolution of Tatra models rather than sudden revolutionary succession, which is typical for auto manufacturers today. In this sense we can see mid-types, which were typical especially for T30 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tatra 600
The Tatra 600, named the Tatraplan, was a rear-engined large family car (D-segment in Europe) produced from 1948 to 1952 by the Czech manufacturer Tatra. The first prototype was finished in 1946. History After World War II, Tatra continued its pre-war business of building passenger cars in addition to commercial vehicles and military vehicles. The factory was nationalised in 1946 two years before the Communist takeover. Although production of pre-war models continued, a new model, the Tatra 600 Tatraplan was designed in 1946-47 by Josef Chalupa, Vladimír Popelář, František Kardaus and Hans Ledwinka. The name of the car celebrated the new Communist planned economy but also referred to aeroplane inspiration ('éroplan' means aeroplane in colloquial Czech).

FR Layout
In automotive design, a FR, or front-engine, rear-wheel-drive layout is one where the Internal combustion engine, engine is Front-engine design, located at the front of the vehicle and rear-wheel-drive, driven wheels are located at the rear via a drive shaft. This was the traditional automobile layout for most of the 20th century. Modern designs commonly use the front-engine, front-wheel-drive layout (FF). It is also used in high-floor Bus, buses and School bus, school buses. Front mid-engine, rear-wheel-drive layout In automotive design, a front mid-engine, rear-wheel-drive layout (FMR) is one that places the internal combustion engine, engine in the front, with the rear wheels of vehicle being driven. In contrast to the front-engine, rear-wheel-drive layout (FR), the engine is pushed back far enough that its center of mass is to the rear of the front axle. This aids in weight distribution and reduces the moment of inertia, improving the vehicle's car handling, handling. The me ...

Flat-four Engine
A flat-four engine, also known as a horizontally opposed-four engine, is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. The most common type of flat-four engine is the boxer-four engine, each pair of opposed pistons moves inwards and outwards at the same time. A boxer-four engine has perfect primary and secondary balance, however, the two cylinder heads means the design is more expensive to produce than an inline-four engine. Boxer-four engines have been used in cars since 1897, especially by Volkswagen and Subaru. They have also occasionally been used in motorcycles and frequently in aircraft. Cessna and Piper use flat four engines from Lycoming and Continental in the most common civil aircraft in the world - the Cessna 172, and Piper Cherokee, while many ultralight and LSA planes use versions of the Rotax 912. Design Most flat-four engines are designed so that each pair of opposing pistons moves inwards and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mid-size Car
Mid-size—also known as intermediate—is a vehicle size class which originated in the United States and is used for cars larger than compact cars and smaller than full-size cars. "Large family car" is a UK term and a part of the D-segment in the European car classification. Mid-size cars are manufactured in a variety of body styles, including sedans, coupes, station wagons, hatchbacks, and convertibles. Compact executive cars can also fall under the mid-size category. History The automobile that defined this size in the United States was the Rambler Six that was introduced in 1956, although it was called a "compact" car at that time. Much smaller than any standard contemporary full-size cars, it was called a compact to distinguish it from the small imported cars that were being introduced into the marketplace. By the early 1960s, the car was renamed the Rambler Classic and while it retained its basic dimensions, it was now competing with an array of new "intermediate" ...

Air-cooled Engine
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. In all combustion engines, a great percentage of the heat generated (around 44%) escapes through the exhaust, not through the metal fins of an air-cooled engine (12%). About 8% of the heat energy is transferred to the oil, which although primarily meant for lubrication, also plays a role in heat dissipation via a cooler. ''Air-cooled engines'' are used generally in applications which would not suit liquid cooling, as such modern air-cooled engines are used in motorcycles, general aviation aircraft, lawn mowers, generators, outboard motors, pump sets, saw benches and auxiliary power units. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head, where the coolant absorbs heat, to a heat ...

Overhead Valve
An overhead valve (OHV) engine, sometimes called a ''pushrod engine'', is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with earlier flathead engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead valves, the common usage of the term "overhead valve engine" is limited to engines where the camshaft is located in the engine block. In these traditional OHV engines, the motion of the camshaft is transferred using pushrods (hence the term "pushrod engine") and rocker arms to operate the valves at the top of the engine. Some early intake-over-exhaust engines used a hybrid design combining elements of both side-valves and overhead valves. History Predecessors The first internal combustion engines were based on steam engines and therefore used slide valves. This was the case for the first Otto engine, which was first succ ...

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] |
