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.

Toyota reveals custom Mark X, Harrier and Prius for Tokyo Auto Salon

Toyota offers a robust lineup of models in markets around the world – ours included – but there are certain models that remain reserved for Japan, and now it has revealed some tantalizingly modified versions for its home market. Arguably chief among them is a version of the Mark X that's been upgraded by GRMN. For those unfamiliar, the Mark X is a rear-drive sport sedan offered in the Japanese Domestic Market, while GRMN (shorthand for Gazoo Racing Masters of Nurburgring) is the street-tuning division of one of the company's racing departments. The confluence of these two Japanese lines brings some enticing upgrades to the sedan, including a new front bumper, carbon-fiber roof, trunk spoiler, 19-inch alloys, sport suspension, upgraded brakes and an interior decked out with sports sedans and steering wheel as well as carbon, piano black and Alcantara trim. Motivation comes from a 3.5-liter V6 driving 316 horsepower to the rear wheels through a six-speed manual transmission and Torsen limited slip differential. Joining the Mark X GRMN are a pair of models enhanced by G's, another one of Toyota's Japan-centric performance lines. There's an Elegance version of the Harrier – similar to the Lexus RX we get Stateside – with a sports suspension dropped by 1.4 inches, upgraded brakes, an aggressively restyled front end and an enhanced interior. Alongside it Toyota has revealed a version of the tall-roofed Prius Alpha (which we know as the Prius V) with a similarly upgraded suspension, refreshed front end styling and interior with sports seats and silver-stitched black interior. All three models are slated to debut at the 2015 Tokyo Auto Salon - Japan's equivalent of the SEMA show - next month at the Makuhari Messe in Chiba.

Toyota teases mysterious RND Concept

Toyota is being very secretive about its newly teased RND Concept. The image above is all that the Japanese automaker is showing at the moment, and it's not much to go by. However, the wait to find out won't be very long, as the automaker is unveiling this very mysterious vehicle on January 26 in the UK. Making the RND even more intriguing is that this isn't just a concept pointing the way towards some nebulous future vehicle. Toyota claims that the model is production ready, and the automaker already has pricing, supply and manufacturing space prepared. We likely shouldn't expect a super luxury sedan or sports coupe, though, because Toyota says that the RND is meant for "the widest possible market." Could it possibly be some sort of inexpensive, electric vehicle like the Renault Twizy, then? With just the hind of a taillight, a slash of chrome and what might be an intake, there's not much styling work to go on here. Although, Toyota is making huge promises about the design; it claims the RND "has the potential to transform the look of every vehicle on the road." It's odd to see an automaker other than Tesla reveal a new vehicle outside of a major world auto show, which piques our interest about what Toyota is doing here. Read the company's press release below and let us know what you think the Japanese automaker is up to in Comments. THE NEW TOYOTA RND CONCEPT: SNEAK PREVIEW First details of new model released ahead of world debut next week Toyota is breaking with motor industry convention by revealing a new product outside the familiar surroundings of an international motor show. Instead its new RND Concept will make its world debut in the UK on 26th January, ready for fast-track development that should see it changing the face of motoring within weeks. The first image released today hints at how the concept's design marks a radical shift in direction for Toyota, taking the "fun-to-drive" qualities of its cars to a higher level. Although presented as a concept, Toyota acknowledges the RND will be unveiled in its production-ready form. Manufacturing and product supply have been secured and on-the-road pricing has been fixed at a level that will make the RND Concept accessible to the widest possible market. Toyota is confident, too, that the RND Concept's impact will go far beyond its own model range, having the potential to transform the look of every vehicle on the road.
