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 CEO talks up 20 new plug-in models in Frankfurt

For years now, Volkswagen has dreamed big, forming plans to become the world's largest automaker. That trajectory includes a big plug-in vehicle push, and the CEO of Volkswagen, Martin Winterkorn, said that his group of companies will bring out 20 more EVs and plug-in hybrids by 2020. The list includes the next Phaeton and the Audi A8. "No commitment to electro-mobility can be any clearer than that," Winterkorn said, according to a VW press release. "Our Group already has the largest connected vehicle fleet on the road. By 2020 we will have transformed all of our new cars into smartphones on wheels." Perhaps most illustrative, Winterkorn admitted that the auto industry has turned a corner. "Technological leadership is no longer solely defined in terms of horsepower and torque," he said. "We are taking the precision, enduring value and quality of our cars into the new, digital world." The VW group is also showing off new plug-in concepts in Frankfurt this week, like the Tiguan GTE and the Porsche Mission E. Winterkorn's prepared remarks do not give out the details of these vehicles, but we'll have all the info from the show floor in short order. Stay tuned. PROF. DR.
