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.

Cost-cutting measures put VW Beetle in jeopardy

Volkswagen is on a mission to cut costs. That means producing more models across its various brands based on the same platforms and powertrains, but the latest word from Germany has it that it will also mean cutting some of the VW brand's less successful models. First on the chopping block, according to German publication Der Spiegel, is the three-door version of the Polo, which will reportedly cede its place to the five-door version exclusively. The elimination of that model alone is said to save VW a good 200 million euros, putting it on its way towards reducing the brand's costs by a targeted five billion euros. The Polo isn't the only one in danger, though. The Eos, as we know, is not due to be replaced, but the future of the Beetle could be in jeopardy as well. The Beetle may be one of VW's most iconic models, but is hardly its most successful in terms of sales. With the 2014 annual report due to be released shortly, the last full-year sales figures had Volkswagen selling 109,517 Beetles in 2013. That may be more than four times the number of Scirocco models it sold, but hardly puts a dent in the 871,413 Jettas, 824,629 Golfs and 725,291 Polos it sold during the same year.

Jay Leno takes a ride in Gabriel Iglesias' classic 1966 VW bus

We've seen Jay Leno driving all manner of vehicles, many of them epically fast. But few (this is side of his steamers, anyway) have been as slow – or quite as beautiful – as this classic 1966 Volkswagen Samba. While many of the vehicles featured on episodes of Jay Leno's Garage have actually been from Jay Leno's own garage, the former talk-show host has been known to feature some interesting rides from fellow comedians. A couple of weeks ago it was Adam Carolla's '68 Lamborghini Islero, and this vintage, pristine VW bus belongs to Gabriel Iglesias. It's in beautiful condition and is a sight to see, even if it has a little trouble making its way down the highway. Or starting up again after a quick snack break.
