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.

Senators want civil, criminal actions against VW

With the Department of Justice just beginning its investigation into Volkswagen's emissions evading diesels, Senators Richard Blumenthal and Amy Klobuchar are pushing for the automaker to be prosecuted to the fullest extent of the law both civilly and criminally. In a letter to Attorney General Loretta Lynch, they press the agency to make its scrutiny "thorough but expeditious." The politicians allege that VW misled people while pumping huge amounts of pollution into the air. The Senators believe that all the information about VW's actions needs to make it to the public eye, and the DOJ must have a strong response to the automaker breaking the law. "Officials at Volkswagen should be granted no get out of jail free card, and the Department should accept no plea agreement with Volkswagen that does not ensure any and all information regarding criminal acts by high level officials is provided to the Department," they write. Senator Blumenthal is no stranger for championing changes in the auto industry as of late. He was an advocate for the General Motors Ignition Switch Compensation Fund and pushed for a similar organization for Takata airbag victims. He has also been a staunch supporter for greater automotive cyber security. Blumenthal, Klobuchar: Department of Justice Should Take Strong Civil and Criminal Actions Against Volkswagen for Any Violations Monday, September 28, 2015 Condemns Volkswagen's actions that misled hundreds of thousands of consumers and resulted in tens of thousands of tons of additional pollution emissions Calls for thorough but expeditious investigation (Washingtion, DC) – U.S. Senator Richard Blumenthal (D-CT) and U.S Senator Amy Klobuchar (D-MN) today urged the U.S. Department of Justice (DOJ) to take strong civil and criminal actions against Volkswagen for any violations following the German carmaker's actions that misled hundreds of thousands of American consumers and resulted in tens of thousands of tons of additional pollution emissions. In a letter to Attorney General Loretta Lynch, the senators called for a "thorough but expeditious" investigation. "Officials at Volkswagen should be granted no get out of jail free card, and the Department should accept no plea agreement with Volkswagen that does not ensure any and all information regarding criminal acts by high level officials is provided to the Department," wrote Blumenthal and Klobuchar. "The U.S.

VW Tiguan grows up, gets bigger

The compact crossover segment continues to do huge business around the world, and Volkswagen is showing just how important the niche is by debuting four versions of the all-new, second-generation Tiguan at the Frankfurt Motor Show. Now riding on VW's MQB platform, the latest version has had a growth spurt, but it has also shed 110 pounds in the process. The first of them will hit the international market in April 2016. While the design is still definitively a VW, the latest Tiguan looks more aggressive and expands to 2.4-inches longer, 1.2-inches wider, 1.3-inches lower. There's also three more inches of wheelbase than the outgoing generation. At the front, the grille stretches all the way across and connects with the headlights to visually widen the look even more. In profile and at the rear, things are now a bit more angular, but the changes give the model a more chiseled style. In Fall 2016, VW will debut an even longer wheelbase body for the Tiguan. According to the company, this version will be aimed directly at customers in the US and China that prefer larger vehicles. The added inches outside translate to more room for passengers and cargo inside. Even with the seats up, there's an extra 1.8 cubic feet for stuff in the back, and those sitting in the rear get 1.1 inches more knee room. As an added amenity, buyers can option a 12.3-inch Active Info display digital instrument panel. Europeans gets a choice of eight engines: four fueled by gasoline and four by diesel. They range in power from 123 to 237 horsepower. Expect far fewer options when the Tiguan eventually arrives on these shores. Both front-wheel drive and 4Motion are available, too. In addition to having standard, 4Motion, and R-Line variants on display in Frankfurt, VW also has the Tiguan GTE plug-in hybrid concept at the show. It combines a 1.4-liter TSI engine and an electric motor mounted to the six-speed DSG to offer a total system output of 215 hp. The 13 kWh lithium-ion battery also lets the PHEV cover 31 miles on electric power and get an estimated 124 miles per gallon on the European cycle. That's not too bad, but the roof also features solar cells that VW claims can add another 621 miles of driving range per year under ideal conditions.
