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.

Autoblog's June 2019 Editors' Picks

Each year we review, test and rate hundreds of brand-new cars, trucks and SUVs. We rate these vehicles using the Autoblog score, giving a select few our Editors’ Pick. Here are the best cars we drove in June 2019. 2019 BMW 8 Series Everyone on the Autoblog staff loves a good grand tourer, so we were excited to get behind the wheel of the revived BMW 8 Series, specifically an M850i Coupe. A good GT needs to be as fast as it is stylish and comfortable, and the new 8 Series delivers. We particularly like the 523-horsepower twin-turbo 4.4-liter V8Â’s copious power and smooth ride quality, even on MichiganÂ’s pockmarked post-winter roads. We dig the interior design, too, though not everyone was in love with the exterior. ItÂ’s not the best-handling car in its class, and doesnÂ’t hide its sizable proportions very well, but itÂ’s still worth a look if youÂ’re looking for a big, fast cruiser.  2019 Ford Expedition Crossovers may be the hottest vehicles on the market, but thereÂ’s still a sizable demand for traditional body-on-frame SUVs like the Ford Expedition. These behemoths offer plenty of space in addition to truck-like capability. We like the Expedition's smooth ride, powerful twin-turbo V6 and sharp exterior design, though the interior can feel a bit cheap, especially on some of the more expensive trims. Adding options quickly puts it into Lincoln Navigator territory, and itÂ’s hard to recommend the Ford over the Lincoln when the latter packs the same capability into a far nicer package. Still, the Expedition is as good or better than the competition in most respects, and thatÂ’s why itÂ’s one of our picks. 2019 Toyota 86 Few cars at any price point are as much fun as the Toyota 86 (and its twin, the Subaru BRZ). We like the 86Â’s balanced chassis and sharp steering, and while itÂ’s not as nimble as its close rival the Mazda MX-5 Miata, the ToyotaÂ’s back seat and trunk make it a more usable vehicle. But while we like the 86Â’s driving position, the rest of the interior feels cheap and dated, especially the infotainment system. We complained about the anemic powertrain back in 2012, and itÂ’s only gotten worse as the years have gone by.

EPA says automakers ahead of schedule for 54.5 MPG by 2025

Remember, the target is 54.5 miles per gallon by 2025. Today, the CAFE level is a little over 30. How we get from here to there is something the US Environmental Protection Agency (EPA) is monitoring closely. Thus, the EPA just released an annual flash report on how the auto industry is progressing towards meeting the nation's fuel economy goals. Overall, the industry is doing almost 10 grams per mile (equivalent) better than the rules require. The good news is that the industry is a bit ahead of schedule. In the report (see page iii), the EPA breaks things down by automaker based only on MY12 numbers. Tesla is at the top of the list (which is ranked by over-compliance with 2012MY CO2 standards), but for our money, the real leader is Toyota. The Japanese automaker built the second-highest number of vehicles (2,020,248, after General Motors' 2,364,374) but racked up the most net 2012 over-compliance credits (13,163,009 metric tons). That's an average of over 6.5 metric tons per vehicle. The next closest is Honda, with just over five metric tons of credits per vehicle. Given the MPG fiasco with Hyundai and Kia, the EPA says, "we are excluding Hyundai and Kia data because of the ongoing investigation into their testing methods," but overall, the rest of the industry has credits worth 25,053,168 metric tons of CO2, which means it's doing almost 10 grams per mile (equivalent) better than the rules require. Go team. For now, the numbers in this report (and there are a lot more of them – get the 59-page PDF for yourself here), can't really be used to understand everything from the first year of the new CAFE program. The EPA writes, "Because the program allows credits and deficits to be carried into future years, at the close of the 2012 model year no manufacturer is considered to be out of compliance with the program. ... Compliance with the 2012 model year standards can't be fully assessed until the end of the 2015 model year." There are a more interesting tidbits in the report, such as the fact that Fisker produced 1,415 model year 2012 vehicles, Tesla made 2,952. Remember, too, that CAFE numbers don't equal the fuel economy you see in your daily drives. In the real world, the 54.5 CAFE level will be about 40 mpg, and the average fuel economy today is around 25 mpg, so we have a ways to go, no matter how you measure it.
