Golden Submarine
The Golden Submarine was an early twentieth century streamlined race car designed and built in 1917 by Fred Offenhauser and Harry A. Miller for Barney Oldfield. AutoWeek said that the vehicle brought Miller "nationwide prominence as a race-car builder". Background Oldfield worked with Miller, who developed and built carburetors in Los Angeles, to create a racing machine that would not only be fast and durable, but that would also protect the driver in the event of an accident. Bob Burman, one of Oldfield's top rivals and closest friends, was killed in a wreck during a race in Corona, California. Burman died from severe injuries suffered while rolling over in his open-cockpit car. Oldfield and Miller joined forces to build a race car that incorporated an enclosed roll cage inside a streamlined driver's compartment to completely enclose the driver. Construction The Golden Submarine was built from aluminum with holes for the driver to look out. The gold color was achieved with a c ...

Desmodromic Valve
:''In general mechanical terms, the word ''desmodromic'' is used to refer to mechanisms that have different controls for their actuation in different directions.'' A desmodromic valve is a reciprocating engine poppet valve that is positively closed by a cam and leverage system, rather than by a more conventional spring. The valves in a typical four-stroke engine allow the air/fuel mixture into the cylinder at the beginning of the cycle and exhaust spent gases at the end of the cycle. In a conventional four-stroke engine, valves are opened by a cam and closed by return spring. An engine using desmodromic valves has two cams and two actuators, each for positive opening and closing without a return spring. Etymology The word comes from the Greek words ''desmos'' (, translated as "bond" or "knot") and ''dromos'' (, "track" or "way"). This denotes the major characteristic of the valves being continuously "bound" to the camshaft. Idea The common valve spring system is satisfactory f ...

1919 Indianapolis 500
The 7th Liberty 500-Mile Sweepstakes was held at the Indianapolis Motor Speedway on Saturday, May 31, 1919. After a two-year hiatus due to World War I, the Indianapolis 500 returned to competition in 1919. Howdy Wilcox won, accompanied by riding mechanic Leo Banks. More than half the field (19 of 33 cars) consisted of rookie drivers, tied for the most ever, excluding the inaugural race where all 40 cars were considered "rookies." Ralph DePalma, the 1915 winner, and the driver who suffered a defeat in 1912, again put in a strong performance. DePalma led 93 of the first 102 laps, and drove the first half at record-breaking speed. Tire problems, however, necessitated a long pit stop, and DePalma finished in 6th place. Rain was a factor during practice, limiting available track time in the days immediately leading up to time trials. Since most teams did not arrive until later in the month, some cars had very limited preparation time. Qualifying was supposed to be held on just one d ...

Milwaukee Mile
The Milwaukee Mile is a oval race track in the central United States, located on the grounds of the Wisconsin State Fair Park in West Allis, Wisconsin, a suburb west of Milwaukee. Its grandstand and bleachers seats approximately 37,000 spectators. Paved in 1954, it was originally a dirt track. In addition to the oval, there is a road circuit located on the infield. As the oldest operating motor speedway in the world, the Milwaukee Mile has hosted at least one auto race every year from 1903 to 2015 (except during U.S. involvement in World War II). The track has held events sanctioned by major bodies, such as the American Automobile Association, AAA, United States Automobile Club, USAC, NASCAR, Champ Car, CART/Champ Car World Series, and the IndyCar Series. There have also been many races in regional series such as ARTGO. Famous racers who have competed at the track include: Barney Oldfield, Ralph DePalma, Walt Faulkner, Parnelli Jones, A. J. Foyt, Al Unser, Bobby Unser, Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ralph DePalma
Raffaele "Ralph" De Palma (December 19, 1882 – March 31, 1956) was an Italian-American racecar driving champion who won the 1915 Indianapolis 500. His entry at the International Motorsports Hall of Fame estimates that he won about 2,000 races. DePalma won the 1908, 1909, 1910, and 1911 American AAA national dirt track championships and is credited with winning 24 American Champ car races. He won the Canadian national championship in 1929. DePalma estimated that he had earned $1.5 million by 1934 after racing for 27 years. He is inducted in numerous halls of fame. He competed on boards and dirt road courses and ovals. Biography Born in Biccari, Apulia, Italy, DePalma's family emigrated to the United States in 1893. As a young man he tried bicycle racing with mixed success, but at the age of twenty-two he began racing motorcycles before switching to the automobile dirt track racing circuit in 1909, the year that the American Automobile Association established the nati ...

Maywood, Illinois
Maywood is a village in Proviso Township, Cook County, Illinois, United States in the Chicago metropolitan area. It was founded on April 6, 1869, and organized October 22, 1881. The population was 23,512 at the 2020 United States Census. History There was limited European-American settlement in the Maywood area before a railroad was built after the American Civil War, which stimulated the rise of Chicago. At least one house in what became Maywood is known to have been used as a station on the Underground Railroad, to aid refugee African-American slaves in escaping to freedom in the North. Some settled in the free state of Illinois; others went on to Canada, which had abolished slavery, seeking further distance from slavecatchers. The site of the former house has been nationally commemorated. The plaque is located at today's Lake Street and the Des Plaines River bridge. This early West Side suburb of Chicago was developed along the oldest railway line that led away from the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Tunnel
Wind tunnels are large tubes with air blowing through them which are used to replicate the interaction between air and an object flying through the air or moving along the ground. Researchers use wind tunnels to learn more about how an aircraft will fly. NASA uses wind tunnels to test scale models of aircraft and spacecraft. Some wind tunnels are large enough to contain full-size versions of vehicles. The wind tunnel moves air around an object, making it seem as if the object is flying. Most of the time, large powerful fans suck air through the tube. The object being tested is held securely inside the tunnel so that it remains stationary. The object can be an aerodynamic test object such as a cylinder or an airfoil, an individual component, a small model of the vehicle, or a full-sized vehicle. The air moving around the stationary object shows what would happen if the object was moving through the air. The motion of the air can be studied in different ways; smoke or dye can be ...

Ignition Magneto
An ignition magneto, or high-tension magneto, is a magneto that provides current for the ignition system of a spark-ignition engine, such as a petrol engine. It produces pulses of high voltage for the spark plugs. The older term ''tension'' means ''voltage''. The use of ignition magnetos is now confined mainly to engines where there is no other available electrical supply, for example in lawnmowers and chainsaws. It is also widely used in aviation piston engines even though an electrical supply is usually available. In this case, the magneto's self-powered operation is considered to offer increased reliability; in theory, the magneto should continue operation as long as the engine is turning. History Firing the gap of a spark plug, particularly in the combustion chamber of a high-compression engine, requires a greater voltage (or ''higher tension'') than can be achieved by a simple magneto. The ''high-tension magneto'' combines an alternating current magneto generator a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spark Plug
A spark plug (sometimes, in British English, a sparking plug, and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within the engine. A spark plug has a metal threaded shell, electrically isolated from a central electrode by a ceramic insulator. The central electrode, which may contain a resistor, is connected by a heavily insulated wire to the output terminal of an ignition coil or magneto. The spark plug's metal shell is screwed into the engine's cylinder head and thus electrically grounded. The central electrode protrudes through the porcelain insulator into the combustion chamber, forming one or more spark gaps between the inner end of the central electrode and usually one or more protuberances or structures attached to the inner end of the threaded shell and designated the ''side ...

Inlet Manifold
In automotive engineering, an inlet manifold or intake manifold (in American English) is the part of an engine that supplies the fuel/air mixture to the cylinders. The word '' manifold'' comes from the Old English word ''manigfeald'' (from the Anglo-Saxon ''manig'' anyand ''feald'' epeatedly and refers to the multiplying of one (pipe) into many.manifold, (adv.) "in the proportion of many to one, by many times". AD1526 ''Oxford English Dictionary'', In contrast, an exhaust manifold collects the exhaust gases from multiple cylinders into a smaller number of pipes – often down to one pipe. The primary function of the intake manifold is to ''evenly'' distribute the combustion mixture (or just air in a direct injection engine) to each intake port in the cylinder head(s). Even distribution is important to optimize the efficiency and performance of the engine. It may also serve as a mount for the carburetor, throttle body, fuel injectors and other components of the engi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single Overhead Cam
An overhead camshaft (OHC) engine is a piston engine where the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam".) engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; however an OHV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barney Oldfield
Berna Eli "Barney" Oldfield (January 29, 1878 – October 4, 1946) was an American pioneer automobile racer; his "name was synonymous with speed in the first two decades of the 20th century". After success in bicycle racing, he began auto racing in 1902 and continued until his retirement in 1918. He was the first man to drive a car at 60 miles per hour (96 km/h) on a circular track. Biography Early life Berna Eli Oldfield was born in York Township, Fulton County, Ohio, near Wauseon and Toledo, on January 29, 1878, to Henry Clay Oldfield, a laborer, and his wife Sarah. He was named after his father's bunkmate in the 68th Ohio Volunteer Infantry during the American Civil War. He had a sister Bertha. As of the 1880 United States Census, the Oldfields lived in Wauseon. In 1889 they moved to Toledo, where the father Henry got a job at the state mental asylum. In the summer of 1891, Berna worked as a waterboy in order to purchase his first bicycle. According to legend, he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
