The tumultuous history of the diesel engine

Volkswagen, diesel's most enthusiastic patron, deceived everyone about the amount of emissions its cars were putting out. We have covered this latest massive automotive scandal in great detail, and there are surely more fascinating revelations to come. It turns out that this is just the latest episode in the epic story of the controversy and intrigue surrounding the diesel engine, and its inventor. This is the story of the tumultuous birth and interesting evolution of the compression-ignition engine at the center of the VW scandal. Napoleon III Got Rudolf Diesel Deported Rudolf Diesel was born in Paris in 1858. His Bavarian parents had settled in France where his father, Theodor, was a leather goods manufacturer. When the French Parliament declared war on Prussia, kicking off the Franco-Prussian war, the Diesels fled to London. When he was 12, Rudolf went to live with his aunt and uncle in the Bavarian university town of Augsburg. It was his parents' hometown, and importantly, it's where Rudolf began studying at the Royal County Trade School. His time in Augsburg, graduating at the top of his class from trade school that laid the groundwork for all that was to come. Diesel Nearly Blew Himself Up An early career in refrigeration saw Diesel running R&D in Berlin for Linde, a company started by refrigeration pioneer Carl Von Linde, one of Diesel's professors. His ambition to branch out beyond refrigeration, and his deep understanding of thermodynamics, led to efficiency experiments with steam engines. Diesel was trying to create an engine that didn't waste heat from the combustion process, therefore getting the most work out of the fuel. Instead, he was nearly killed when an experimental ammonia vapor steam engine exploded. Recovery took many months, and during some of that time, he was no doubt planning his next experimental engine, based on the theoretical Carnot cycle. His Engine Was An Attempt To Stick It To The Man Steam engines were expensive to run and wasteful. Diesel thought the efficiency of his design would be a way for the small business to compete with the dominant industrial giants. It was, and it did, but big business is equally passionate about chasing efficiency. Diesel engines quickly proliferated in industries both grand and cottage. Rudolf Didn't Really Invent The Diesel As We Know It Instead, he improved an existing one to a significant degree. The Diesel engine could be considered an evolution of the "hot-bulb" engine.

Honda Civic overtakes Toyota Corolla as America's best-selling compact

The battle to claim October's best-selling compact sedan title has been won by the Honda Civic. The Japanese four-door sold 27,328 units, leaving the Toyota Corolla - September's title holder - in its wake with 23,637 units sold. In terms of year-to-date sales, the Civic sits at 280,899 units, with the Corolla trailing at 257,184 vehicles.
Sitting in third place, separated by a significant gap from the leaders, is the Chevrolet Cruze with 16,087 units sold. The Ford Focus earned fourth, with 15,108 units moved out of showrooms. (It is interesting to note that while the Civic and Corolla have both enjoyed double-digit sales increases year-over-year, the Cruze and Focus have seen significant decreases during the same period.)
Sales of the Hyundai Elantra hit 14,876 units, putting it in fifth place, with the Volkswagen Jetta earning sixth place with 11,710 units. Rounding out the ten top sellers were the Nissan Sentra (8,399 units), Mazda3 (7,647 units), Dodge Dart (5,617 units) and Subaru Impreza/WRX (4,923 units). The Kia Forte (4,706 units) and Volkswagen Golf (2,249 units), eleventh and twelfth respectively, have fallen behind.
