cars The first design for an American automobile

The first design for an American automobile with a gasoline internal combustion engine was made in 1877 by George Selden of Rochester, New York. Selden applied for a patent for an automobile in 1879, but the patent application expired because the vehicle was never built. After a delay of sixteen years and a series of attachments to his application, on November 5, 1895, Selden was granted a United States patent (U.S. Patent 549,160) for a two-stroke automobile engine, which hindered, more than encouraged, development of automobiles in the United States. His patent was challenged by Henry Ford and others, and overturned in 1911.
In 1893, the first running, gasoline-powered American car was built and road-tested by the Duryea brothers of Springfield, Massachusetts. The first public run of the Duryea Motor Wagon took place on September 21, 1893, on Taylor Street in Metro Center Springfield. To construct the Duryea Motor Wagon, the brothers had purchased a used horse-drawn buggy for $70 and then installed a 4 HP, single cylinder gasoline engine. The car had a friction transmission, spray carburetor, and low tension ignition. It was road-tested again on November 10, when the The Springfield Republican newspaper made the announcement. This particular car was put into storage in 1894 and stayed there until 1920 when it was rescued by Inglis M. Uppercu and presented to the United States National Museum.
In Britain, there had been several attempts to build steam cars with varying degrees of success, with Thomas Rickett even attempting a production run in 1860. Santler from Malvern is recognized by the Veteran Car Club of Great Britain as having made the first petrol-powered car in the country in 1894[23] followed by Frederick William Lanchester in 1895, but these were both one-offs. The first production vehicles in Great Britain came from the Daimler Motor Company, a company founded by Harry J. Lawson in 1896, after purchasing the right to use the name of the engines. Lawson's company made its first automobiles in 1897, and they bore the name Daimler.
In 1892, German engineer Rudolf Diesel was granted a patent for a "New Rational Combustion Engine". In 1897, he built the first Diesel Engine. Steam-, electric-, and gasoline-powered vehicles competed for decades, with gasoline internal combustion engines achieving dominance in the 1910s.
Although various pistonless rotary engine designs have attempted to compete with the conventional piston and crankshaft design, only Mazda's version of the Wankel engine has had more than very limited success.
