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 Jetta and Golf family earn IIHS TSP+ [w/video]

Volkswagen is the latest manufacturer to add vehicles to the growing list of cars, trucks and SUVs certified as Top Safety Pick+ by the Insurance Institute for Highway Safety. The non-profit has awarded its highest safety ranking on the 2016 Golf and Jetta families. Earning a TSP+ rating, while increasingly common, is still a challenge for automakers thanks to IIHS' strict testing regime. Vehicles must net "Good" ratings – the highest grade available – in the moderate overlap, front, side, roof, and head-restraint tests, while also scoring an "Acceptable" rating on the notoriously tricky small-overlap test. On top of that, the automated crash-prevention systems need to be rated as either "Advanced" or "Superior." For 2016, the Jetta, Golf, and their performance variants retained 2015's "Good" ratings across the board, while also receiving an "Advanced" crash prevention rating, thanks to the new-for-2016 Forward Collision Warning and Autonomous Emergency Braking systems. "This year's Top Safety Pick+ awards demonstrate Volkswagen's longstanding commitment to vehicle safety and the development of innovative technologies," Mark Barnes, VP of Sales for VW of America, said in the attached statement. "Our available driver assistance systems and safety features show Volkswagen's commitment to introduce systems that were once only seen on high-end luxury and premium vehicles, such as Adaptive Cruise Control and Lane Departure Warning." Scroll down for the official press release from VW and video of the crash test (and yes, that's a 2015 shown in both the lead image and video – the only difference between the two years was the availability of more advanced crash-prevention systems).
