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.

2013 Toyota RAV4

A Nicer View Than Ever Of Middle Of The Road
When we had our first shot behind the wheel of the 2013 Toyota RAV4, the overall judgment from Managing Editor Jeremy Korzeniewski could be summed up in a sentence along the lines of, "Eh, not bad." The truth is that the compact crossover segment, now filled with not-so-compact offerings, is as cutthroat as any in the industry these days. When a heavyweight player like the RAV4 comes to market with a new generation, it is not at liberty to start from a clean sheet, lest it throw cold water on a vehicle that sells tens of thousands of units globally every month. Like De La Soul says, "Stakes is high."
If the choices in the marketplace were still largely limited to the Honda CR-V, as was the case when this market niche was green, the Toyota offering might actually seem like the exciting choice. But with new players offering better dynamic thrills (Mazda CX-5), cool turbo motors and fancy technology (Ford Escape), or even crunchy cred (Subaru Forester), the small crossover shopper is really spoiled for choice in 2013.

Toyota sells 3-millionth Prius

Three generations in sixteen years and more than three million units sold worldwide - as of the end of June, those are the stats on the Toyota Prius. Even though Toyota says Prius sales might not reach the goal of 250,000 units this year, the little hybrid that could still doesn't have any problem flying off dealer lots. The second-generation Prius sold 1.2 million examples in its eight-year lifespan, and the third generation, introduced in 2009, has sold 1.7 million examples in just four years.
Toyota is also touting its investment in future powertrains, some 790 billion yen ($7.9 billion US) on research and development into new platforms and components, and "environmental technology development."
The press release below has more details, the future undoubtedly has more Priuses Prii in it.
