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.

Regulators consider adding more carmakers to Takata recall

Volkswagen's diesel emissions scandal has been getting a lot of press recently, but the Takata airbag inflator affair could be grabbing headlines again soon. According to Bloomberg, the National Highway Traffic Safety Administration is contemplating an expansion to the campaign that could add seven automakers to the 12 already affected. They are Jaguar Land Rover, Mercedes-Benz, Spartan Motors, Suzuki, Tesla, Volvo Trucks, and VW Group. To be clear, there's no recall for any of these automakers, yet. The government is simply asking for a full list of vehicles that each of them have with Takata-supplied inflators containing ammonium nitrate propellant. The agency is concerned this substance could play a roll in the ruptures. "NHTSA is considering not only whether to issue an administrative order that would coordinate the remedy programs associated with the current Takata recalls, but also whether such an order should include expansion of the current recalls," the letters say. All seven can be viewed, here. From a report supplied by Takata, the government already knows that the company supplied 887,055 inflators with ammonium-nitrate propellant to VW and 184,926 of them to Tesla. In an incident during the summer, a side airbag allegedly burst in a 2015 VW Tiguan. In early September, NHTSA put out a revised report that there were 23.4 million inflators to be replaced in 19.2 million vehicles in the US. An earlier accounting from the agency had about 34 million of the parts in 30 million cars. High humidity is still believed to be among the biggest risk factors for the ruptures. Although, if ammonium nitrate also gets the blame, some already recalled models might need to be repaired again. Related Video:

Volkswagen Group Chairman Ferdinand Piech resigns

Ferdinand Piech, Volkswagen Group's chairman of the supervisory board, has resigned from the company. His wife, Ursula, has also left her position on the board. A statement put out by VW in German said the move was due to the fact that "mutual trust is no longer present," and the board's deputy chairman, Berthold Huber, will be interim chairman. It's been just two weeks since Ferdinand Piech told Germany's Der Spiegel magazine that he didn't want Group CEO Martin Winterkorn to become the next chairman and that he was keeping the CEO at a distance. That public comment surprised just about everyone, and led to a meeting in Piech's office in Austria. The leadership committee supported Winterkorn, and that was backed up by official, pro-Winterkorn messages from VW labor leaders and the German state of Lower Saxony. After that meeting, Piech agreed to support Winterkorn in public, but it was widely suspected that the fight wasn't over. Now it might be. This is not a changing, but rather an explosion of the guard. Piech lived for VW, and he and his Porsche kin still have a 51-percent stake in the Volkswagen Group. Frankly, we have a feeling that this still isn't over. The official statement from VW in English is below. Statement of the Executive Committee of the Supervisory Board of Volkswagen AG Wolfsburg, 25 April 2015 -- The Executive Committee of the Supervisory Board of Volkswagen AG discussed again today in detail the situation of the Volkswagen Group. 1.: The members of the Executive Committee have unanimously determined that in view of the background of the last weeks the mutual trust necessary for successful cooperation no longer exists. 2.: For this reason Professor Dr. Ferdinand K. Piech has resigned with immediate effect from his position as Chairman of the Supervisory Board and from all his mandates as a Supervisory Board member within the Volkswagen Group. In addition, Ms. Ursula Piech has resigned with immediate effect from all her Supervisory Board mandates within the Volkswagen Group. 3.: The position of Chairman of the Supervisory Board will be temporarily assumed by the Deputy Chairman Berthold Huber. Mr. Berthold Huber will chair both the Supervisory Board meeting on May 4 as well as the Annual General Meeting on May 5, 2015. 4.: Under the chair of Mr. Berthold Huber the representatives of shareholders and employees will in close cooperation determine the candidate for the new Chairman of the Supervisory Board.
