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.

Here are the best-selling cars and trucks from January 2015

Every month, Autoblog slogs through all the sales figures reported by automakers that do business in the United States, and, after a little bit of sorting, we put it into an easy-to-read chart in an attempt to make it as easy as possible to follow the ins and outs of sales and shipments. But that only covers the brands themselves, not the individual models they sell. And we think you'd all be interested in knowing which vehicles beat their rivals in sales from month to month, so we've put together this handy gallery to keep you in the know. While the leader of the pack may not come as much of a surprise, the order that the top ten finishes in changes frequently – due to automaker deals, the price of gas, etc. – and we've included some statistics to help you see how their current performance stacks up to month's past.

Recharge Wrap-up: Toyota i-Road and COMS in France, Tesla tours Northeast, EV attitudes in UK

Toyota's i-ROAD and COMS teeny, tiny, city EVs are joining the Citelib carsharing fleet in Grenoble, France. The ultra-compact EVs, which will become available in October, are meant to supplement the Grenoble metropolitan area's existing public transit infrastructure, which includes trams, buses and trains. Toyota's i-ROAD and COMS will be connected to the transit systems IT infrastructure, allowing users to visualize their route on their smartphone or computer, and reserve and pay for their car before they get dropped off near the charging station (or the other way around). Then, the user finishes (or begins) their trip with one of the EVs. Surveys show that use of public transport is increasing in Europe, but most users still have to walk 15 minutes or so to reach their destination. Adding the i-ROAD and COMS carsharing service to their commute makes the trip into the city center quicker and more flexible, while keeping the air clean. See more below. Toyota is providing 70 vehicles to the Citelib program as part of a three-year test, while French energy company EDF is contributing 30 charging stations to the project. The i-ROAD is a three-wheeled EV that seats two people, and it features Active Lean technology for stability and comfort in the corners. Its footprint is about one-fourth that of a regular car. The four-wheeled COMS EV seats one, but also features a small storage compartment in the rear. The Tesla Model S is going on tour throughout the Northeastern US to give test drives to the public. Beginning July 4 in Montauk, NY, and ending August 30 in Vergennes, VT, people will get the chance to take a 15-minute spin in what many consider to be the best electric car available as part of Tesla's Fully Charged tour. If you live in New York, New Jersey, Massachusetts, Maine, Connecticut, New Hampshire or Vermont, the Model S may be coming to a town near you (check the schedule here) and you'll get the chance to drive the car with a product specialist in the passenger seat to answer your questions. You can even bring up to three guests in the back seat. So if you live in one of the states where Tesla can't sell cars or doesn't have a store, this is your chance to get to know the vehicle and decide if you want to buy one. Or you can just see what it feels like to silently go from 0-60 in 4.2 seconds (hint: it's pretty cool). A UK Survey shows five percent of people there are considering buying an electric vehicle.
