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 Mirai offers promising tech, unfortunate looks

Is there some rule that all cutting-edge, ultra-efficient or emissions-free vehicles need to look, uh, weird? No? Then would anyone care to explain the Toyota Mirai, a vehicle that for all it's hugely, wildly promising technology, will forever be pigeonholed based on its odd styling? Looks aside, the Mirai represents a big gamble for Toyota, which isn't only selling a hydrogen-powered car – a risky venture in itself – but teaming up with Air Liquide to build 12 hydrogen filling stations across the northeast. And once that's done, it plans on leasing the $57,000 sedans for just $499 month, a figure that includes free hydrogen (there is a reason for that, though). Like we said, this is a big gamble. Of course, we still can't get over its looks, which you can more closely analyze in our live gallery, available above. Have a glance. This content is hosted by a third party.

THE FUTURE HAS ARRIVED, AND IT'S CALLED MIRAI President Akio Toyoda announces name of fuel cell sedan in web video CEO Jim Lentz announces expansion of Toyota fuel cell infrastructure investment to five-state Northeastern corridor NEWPORT BEACH, Calif., (Nov. 16, 2014) – Akio Toyoda has seen the future, and it's called "Mirai." That's the name of Toyota's new fuel cell vehicle, which the company's president announced in a video released the night before the car's official launch. Mirai, which means "future" in Japanese, represents a turning point for the automotive industry. The groundbreaking vehicle can travel up to 300 miles on a single tank of hydrogen, refuel in less than five minutes and emits only water vapor. Expanded Support for New Hydrogen Stations Of course, the car of the future won't become a reality without the hydrogen stations to support it. That's why Toyota North America chief executive officer (CEO) Jim Lentz announced a new commitment to drive the development of a hydrogen refueling infrastructure in five northeastern U.S. states. To support Mirai's introduction to the region in 2016, Toyota is collaborating with Air Liquide to develop and supply a phased network of 12 state-of-the-art hydrogen stations targeted for New York, New Jersey, Massachusetts, Connecticut, and Rhode Island. The states and locations have been strategically selected in the greater New York and Boston areas to provide the backbone of a hydrogen highway for the Northeast corridor.

Impala crashes into Land Cruiser... to hide from a cheetah

What would you do if a wild animal jumped into your vehicle through an open window during an African safari? What if said animal was an impala being chased by cheetahs? Though the scenario seems unbelievable, that's just what happened to a group of tourists in Kruger National Park in South Africa, and it was all caught on video.
With the tour groups stopped, a motorist with a video camera handy happens to catch the unlikely sight of a herd of impalas (not that kind of Impala) jumping over the tarmac while being followed, quickly of course, by two cheetahs. The feline predators thought they had cornered one impala and were closing in for the kill when it jumped through the open window of a Toyota Land Cruiser Prado - South Africa's version of the Lexus GX. Fortunately for the occupants of said vehicle, the cheetahs did not follow.
A short while later, one of the occupants in the Toyota fearlessly opens a door to let the poor animal out. It must have been its lucky day, because the cheetahs didn't take pursuit. Check out the circle life get interrupted by this traffic jam in the video below.
