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 adds more than 1.1 million vehicles to previous fuel pump recall

A Toyota and Lexus recall that previously listed nearly 700,000 potentially affected vehicles has been amended to include more than 1.1 million new rides. Overall, more than 1.8 million cars, trucks, crossovers, and SUVs are part of a voluntary recall regarding fuel pumps that might stop working.    On January 13, 2020, Toyota announced a safety recall for 695,541 Lexus and Toyota models. It included the Toyota 4Runner, Camry, Highlander, Land Cruiser, Sequoia, Sienna, Tacoma, Avalon, Corolla, and Tundra, plus the Lexus LS 500, LC 500, RC 350, RC 300, GS 350, IS 300, ES 350, LX 570, GX 460, RX 350 NX 300, RX 350L, and GS 300. The Avalon, Corolla, NX 300, RX 350L, and GS 300 in the initial recall were specifically 2019 model years, while the rest were 2018-2019.  Today, March 4, 2020, Toyota stated it has expanded the recall to approximately 1.8 million vehicles total. Toyota did not provide a specific number, but here is the full list of potentially affected cars:  2013-2015 Lexus LS 460 2013-2014 Lexus GS 350 2014 Toyota FJ Cruiser, Lexus IS-F 2014-2015 Toyota 4Runner, Land Cruiser; Lexus GX 460, IS 350, LX 570 2015 Lexus NX 200t, RC 350 2017 Lexus IS 200t, RC 200t 2017-2019 Toyota Sienna; Lexus RX 350 2018 Lexus GS 300 2018-2019 Toyota Avalon, Camry, Corolla, Highlander, Sequoia, Tacoma, Tundra; Lexus ES 350, GS 350, IS 300, IS 350, LC 500, LC 500h, LS 500, LS 500h, RC 300, RC 350, RX 350L On these vehicles, a low-pressure fuel pump inside the fuel tank could fail. If this fuel pump fails while the vehicle is in use, the vehicle could sputter and stall. Without warning of the impending malfunction, other than some lights on the dashboard, this could present a dangerous situation for the driver.  For all affected vehicles, Toyota and Lexus will replace the faulty parts with "improved" fuel pumps. Notifications will start in May. Recalls Lexus Toyota

Toyota and Lexus recalling 235,000 hybrid CUVs and sedans over separate issues

When it rains, it pours. Toyota has announced a pair of separate but voluntary North America recalls covering approximately 235,000 vehicles built between 2006 and 2011. The larger of the two recalls targets Toyota's hybridized crossovers, the Lexus RX400h and Toyota Highlander Hybrid. 133,000 units, including 2006-2010 Highlander and 2006-2008 RX crossovers are covered in the campaign. The other recall affects 102,000 IS350 sedans, IS350C convertibles and GS350 sedans built between 2006 and 2011.
With the CUVs, the faults in the parallel circuits of the transistors can cause heat damage in the inverter assembly, triggering an abundance of warning lamps and sending the vehicle into limp mode. The Lexus sedans are being recalled due to loose bolts on the variable valve timing controller. Detected by unusual underhood sounds on startup, the issue can cause the engine to stop while driving. The inverter issue is also triggering similar recalls in Japan and Europe.
At the moment, it's unclear if any of these issues have caused any crashes or injuries. Toyota says it plans to notify owners of the recall via snail mail. Additional information for owners can be found on the recall sites for Toyota and Lexus or by calling Toyota's customer service line, at 1-800-331-4331.
