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.

Volkswagen showcasing latest emergency vehicles at RETTmobil

RETTmobil may not be the top show on our calendars, but it's the top destination for police and emergency vehicles in Europe. The show opens this week in Fulda, Germany, and Volkswagen has revealed some of the vehicles it'll be presenting to first responders there this year. Leading the charge will be the new Golf Alltrack that has been set up specially as a command car, with special lighting, graphics and equipment like an accident data recorder and unique control panel. It'll be joined as well by specially equipped versions of the Passat, Tiguan and Touareg. Volkswagen Commercial Vehicles will also be on hand to showcase an Amarok pickup set up as a beach patrol car (you know, just in case Hasselhoff happens to be in town for the show), as well as a Transporter T6 van set up as an armored personnel carrier and a Crafter ambulance. Volkswagen prasentiert sich auf der RETTmobil 2015 - Golf Alltrack erstmals als Kommandowagen vorgestellt - Transporter T6 feiert Premiere als Mannschaftstransportwagen Hannover / Fulda, 4. Mai 2015 – Mit einer vielfaltigen Produktpalette prasentiert sich Volkswagen ab dem 6. Mai auf der RETTmobil 2015. Messehighlights sind der neue Volkswagen Transporter, der seine Premiere als Mannschaftstransportwagen feiert und der neue Golf Alltrack, der dort erstmals als Kommandowagen zu sehen ist. Bis zum 8. Mai konnen sich Besucher auf der internationalen Leitmesse fur Rettung und Mobilitat in Fulda uber Sonderfahrzeuge fur Rettungseinsatz und Krankentransport informieren. Am Volkswagen Messestand (Halle 3, Stand 303) prasentieren ein speziell ausgestatteter Golf Alltrack und ein Passat Variant 4Motion, das vielfaltige Leistungsspektrum der Marke Volkswagen Pkw fur den Rettungseinsatz. Beide Modelle sind als Kommandowagen aufgebaut und verfugen uber eine umfangreiche Sonderausstattung fur den Einsatz-betrieb wie etwa Digitalfunkvorbereitung, ein Sondertastenbedienfeld und eine Sondersignalanlage mit Blaulichtleuchte. Die Fahrzeuge sind ausserdem mit dem Unfalldatenspeicher UDS ausgestattet, der den Ablauf eines Ereignisses gerichtsverwertbar dokumentiert. Ein besonderes Messehighlight ist der neue Transporter T6 als Mannschaftstransportwagen. Das beliebte Einsatzfahrzeug von Feuerwehr und Rettung wird farblich passend in Rot-Weiss vorgestellt und bietet mit bis zu funf Einzelsitzen viel Platz fur das Einsatzpersonal und die notwendige Ausrustung.

Carmakers say they 'can't meet' Euro 6 emissions targets

UPDATE: A previous version of this story listed Euro 6 requirements in kilograms per kilometer. This was incorrect. The correct unit is grams of NOx per kilometer, or g/km. The story has been edited accordingly. Well, the timing of this is not good. In the midst of Volkswagen's emissions cheating scandal, the European Automobile Manufacturers Association (ACEA) is claiming it won't be able to hit the stringent Euro 6 nitrogen oxide standards currently slated for the end of the decade. Currently, European legislators are set to begin requiring tougher emissions standards by 2017. Standards would be ramped up until 2020, when all new cars sold across the pond would be required to emit just 0.080 kilograms of nitrogen oxide per kilometer. That's too tough for automakers, though. Citing an "EU insider," AutoExpress reports that automakers are asking for conformity factors, which is a fancy way of saying they want easier standards. The automakers are requesting a conformity factor of 2.75 from 2017 to 2020, and a factor of 1.7 in 2020. What that means is that by 2020, new diesels would be allowed to emit 1.7 times the 0.080 g/km standard, or 0.136 g/km. While that might not be all that bad, if automakers were granted the 2.75 conformity factor, new diesels from 2017 wouldn't even be eligible for today's Euro 5 classification, AE claims. Far and away the most astonishing thing here though, is the way the ACEA is viewing the VW diesel scandal. According to AE, the EU insider said automakers across the pond think there's "a US conspiracy against European diesels." Yep. Volkswagen installed software on millions of vehicles to cheat emissions tests and it's somehow an American conspiracy. That makes loads of sense. To put it simply, automakers don't think their diesels will be able to hit European standards, so they're asking for a break. Whether European legislators go along with it remains to be seen.
