The history of the automobile goes back several hundred years. Of the the One <br>EARLIEST Attempts to the propel the vehicle by a mechanical power WAS SUGGESTED by Sir by Isaac <br>Newton about 1680. <br><br><br>HOWEVER, the credit for building the first the self-propelled road the vehicle a must <br>undoubtedly! Go to the French military engineer Have, it Author Nickolas Cugnot. Between 1763 and <br>1769 two steam-driven carriages were built and tried. <br><br>In 1784 the Russian inventor Kulibin built a three- wheeled carriage. A His with In <br>the vehicle of He Used for the first time such new elements as with the brakes, rollers and gear-box. <br><br>First Englishman to of The the build a full-size bed the self-propelled the vehicle for use on the <br>Roads and to Obtain Practical results WAS Trevithick. Between 1798-1800 he built<br>several working models. <br><br><br>Up to 1860 all road vehicles will most Were powered by steam engines, the which ran <br>AT SLOW SPEEDS. In 1860 Paris You built of Lenoir an internal the combustion engine, the which <br>ran on o city gas, the gas being of Ignited by an spark The description electric. In 1866 Invented the Otto <br>of the type of four-cycle engine stroke of the which is today has been Used. <br>But Surely the Slowly auto the industry is perfecting a number of alternatives this is to the <br>Conventional engines found! In by Almost all of today has been's passenger cars. <br><br>Prime factors lie Two behind the search for different engines - the necessity to <br>reduce air pollution by requiring auto exhaust cleaner and the desire to produce cars <br>that will run farther on a gallon of fuel.<br>Basic research is the While Continuing on description electric and steam-powered engines, IT <br>the A diesel, turbine and Stirling That the industry are current favorites. <br><br><br>The get better the mileage Diesels than a gasoline engines, and the fuel is Usually <br>cheaper. Disadvantages of diesels of The as with the passenger-car-engines are SLOW performance, <br>noise and smoke. <br>Investigating the companies the All diesels are Trying to the reduce noise and smoke, <br>But the Problems view are not yet solved Entirely. The 28,000 dollar even the Mercedes clatters <br>the when the Started on a cold by morning. The warm up closeup And period for all diesels Seems of too <br>long to drivers become accustomed to a gasoline models The. <br><br><br>Say The the the Experts Stirling is the will most Promising for Among the Favored a three <br>engines.<br>The Stirling concept, first offered more than 150 by a ago years Scottish <br>clergyman, involves external instead of internal combustion. In 1816 Stirling by Robert <br>patented a new engine for pumping water out of Mines and quarries. Could the run on It <br>by Almost the any fuel. <br><br>Typical internal the combustion unlike engines, the Stirling engine is powered by <br>heat from an external-source. The new design with In, hydrogen gas is is heated by a burner, <br>the which CAN on the run Virtually all kind of fuel. Then expands Hydrogen, enters one <br>cylinder and pushes a sliding piston. Piston moves of As, IT Forces gas out of the OTHER <br>end of the cylinder; the emerging gas is cooled and then moves towards an adjacent<br>cylinder where heat is applied once more and the process is repeated. <br><br><br>Point out that Engineers a Stirling engine would be quieter than an equivalent <br>internal combustion engine, would emit less toxic gases, and would use fuel more <br>economically. Having no need for valves or cams, it would also have fewer parts. <br><br><br><br>Old's dream Stirling of might yet Become reality - Perhaps by the end of the Twentieth <br>century. <br>Now! Just, since experts the seek fuel - saving, less See - polluting the alternatives this is to the <br>modern auto engine, Striling's machine has the Started a new life:, for They show For great <br>Interest in the work of a giant Dutch electronics the firm, the which has tested Stirling <br>prototypes in boats, large pumps and even buses. In 1972 Ford signed an agreement<br>with the firm for joint development of a Stirling engine for passenger cars. <br><br>For description electric cars of As, Several types of small battery - powered vehicles are in <br>a production, But IT is for They will most Unlikely That will of the replace more Conventional vehicles. <br>By Yet, there is opinion You to still in the auto the industry That the Conventional a gasoline <br>powered engine - of the type on the Used by Almost universal now! Just - will of 'continue' to Dominate <br>until, outside Circumstances Dictate Otherwise.
