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.

VW suspends sales in South Korea ahead of government meeting

Volkswagen and Audi have announced they will suspend sales of 79 different models in South Korea ahead of a meeting with the country's environmental ministry. VW will halt sales starting on July 25, the same day that its officials are to sit down with the South Korean environmental ministry, which will likely punish the German company. The Wall Street Journal reports that Korea's response to the situation will likely come in the form of an outright sales ban on Volkswagen products by revoking certifications on 79 different models based on 34 different vehicle types. Affected models include the VW Golf, Jetta, and Tiguan and the Audi A3 and A6, the WSJ reports. Essentially, it looks like VW is merely trying to get out ahead of the South Korean government. If the revocation goes through, it'd likely lead to fines and a relatively large recall of around 79,000 vehicles, the WSJ reports. Despite the dreary forecast, Volkswagen reaffirmed its commitment to the South Korean market. "This decision doesn't mean that Volkswagen is pulling out of Korea, which is a very important market to us," a Korean rep for the company said in a statement. "We'll reapply for certification of our cars if the government revokes it. The process may take several months." While Volkswagen's diesel emissions testing scandal is part of the problem, South Korea is taking a harder line than a lot of other countries. Authorities indicted a Volkswagen exec on charges of submitting falsified emissions documents and noise tests last week, while separately, Korea's trade watchdog is considering criminal charges against execs, according to the WSJ. Banning VW Group sales in South Korea isn't quite as dramatic as if the company stopped sales in China, the United States, or Germany, but it's still going to sting. VW Group products (including Bentley) represented around a third of European cars imported by South Korea last year.
