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 twin-turbo V8 patent unearthed

An unremarkable patent focusing on a minor engine part has revealed that Toyota is at least considering a twin-turbo V8. While the filing is most likely just a large company protecting its intellectual property, it could also be a small glimmer of hope that Toyota, a storied company that's made some glaring missteps with enthusiasts in recent years, can leave the ICE party with a bang for the ages. The patent for a secondary PCV separator, whose function is to isolate exhaust gas from lubricating oil, was discovered by a member of the GR86 forum. In this case, it's not engine oil that's the culprit, but turbocharger oil. From a twin-turbo V8. The patent starts out with an almost embarrassingly hilarious stick figure drawing of a car and where said engine would be located (in the front, under the hood, duh). It has the words "Internal Combustion Engine" printed on a rectangle in case there was any doubt. However, the second figure shows a dual turbo setup nestled in the valley of a V8. It's a prime location for reducing turbo lag and optimizing throttle response (and should necessitate a substantial hood bulge as well). Now, interestingly, the forum member believes this engine will be installed in the next Tundra (and presumably Sequoia), but our own research indicates that the pickup will have a 3.5-liter twin-turbo V6 under the hood. With all due respect to the GR86 members, we're going to stand by that assertion and cross our fingers that the patent hints at something even better. That would be a high-performance Lexus, possibly an IS F or, if the ICE gods will allow it, an LC F. After all, we have had reports from Japan that a trio of F-cars were coming, including a LS F. It would explain why the 472-horsepower, V8-powered IS 500 was called the Sport Performance instead of full-on IS F. In fact, Lexus reps have promised that the F label would become even more performance oriented. A proper IS F would be a fitting sendoff to Toyota's high-performance V8, but the tested, then reportedly canceled, then reportedly revived LC F would be an even more melodious swan song. The flagship grand tourer could very well allow loyalists to forgive the aforementioned gaffes. Toyota president and noted car guy Akio Toyoda has taken heat for questioning the coming outright ban of ICE sales in his home country of Japan. Perhaps this engine is one of the reasons he's objecting.

Junkyard Gem: 1992 Lexus SC 400

After Toyota stunned the automotive world with the Lexus LS 400 in 1989, offering a majestically engineered luxury sedan with an all-new DOHC V8 at less than half the cost of its Mercedes-Benz 560 SEL rival, what could be done to follow that (other than a money-printing Lexus-badged Camry, that is)? Clearly, the missing piece of the Lexus branding puzzle at the time was a sports coupe, something to extract the money of car shoppers considering, say, a new Mercedes-Benz 300 CE or Acura Legend coupe. That car turned out to be the Lexus SC, styled in California and known as the third-generation Toyota Soarer in Japan. Here's one of the very first SCs sold in the United States, found in a Denver-area self-service yard last month. These cars had intimidatingly good build quality (I know, because I dismantled a '92 SC 400 down to its smallest components a while back), clearly designed to last at least a quarter-million miles with routine maintenance. This one got hit hard in the right rear, however, and it wasn't worth repairing the damage to a non-SUV pushing three decades of age. Americans could buy a six-cylinder version, the SC 300, which came standard with a five-speed manual transmission (almost all buyers "upgraded" to the automatic, of course). This car is the SC 400, which means it has the same 1UZ-FE V8 engine as the LS 400. That's 250 super-smooth horses and six-bolt main bearing caps keeping the crankshaft from going anywhere it shouldn't. The SC 400 never was available with a manual transmission, nor was its SC 430 successor. This one has the mandatory Aisin-Warner four-speed automatic. This content is hosted by a third party.

These cars were very quiet and comfortable and they could cruise all day at triple-digit speeds, but a curb weight pushing 3,600 pounds meant that the SC 400 wasn't going to beat its Porsche 928 rival on a race track. Actually, the 1992 928S4 cost more than twice as much as the 1992 Lexus SC 400 ($80,920 versus $37,500) and had both a more powerful (326hp) V8 and available manual transmission; perhaps the 1992 Cadillac Eldorado Touring Coupe ($32,470, 200hp V8, automatic) was a more realistic sales rival for today's Junkyard Gem.
