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.

2015 Volkswagen GTI: Clicking, beeping, and trying to stay cool [w/video]

My first car didn't have air conditioning. Well, that's not entirely true. The car had A/C, it just didn't work. Nevertheless, I survived summer after summer of sweating behind the wheel – par for the course in a 15-year-old Mitsubishi with 235,000 miles on the odometer. But it's another thing entirely when that same experience happens in a 2015 Volkswagen GTI after just 7,000 miles of use. That's how Autoblog kicked off summer with the long-term GTI: sweating in plaid seats. The car went to Suburban Volkswagen in Troy, MI, where the technicians told me the air-con just needed a recharge (despite asking them to inspect it further). They recharged it, the air blew cold, and 48 hours later, the A/C stopped working again. (Surprise!) The problem was a leak in the compressor/condenser line, so a new one was installed, the system was charged, and now it's fixed. For real this time. Unfortunately, that second-coming happened during a road trip with editor-in-chief Mike Austin at the helm. His logbook comments are, as you'd expect, appropriately salty. "Everybody loves the GTI, right? Not quite. I drove to Toronto for a weekend. On the way home, the A/C quit working. This wasn't too much of a problem until we hit the border control line to re-enter the United States. I always pick the slow line, somehow. Thusly baked in the heat, with outside temperatures above 80, the GTI didn't cool back down for the rest of the trip. Then I learned we already fixed the A/C once." "Of course, any car on that day with a surprise A/C failure would earn my ire," Austin notes. "It just seems a little more irritating on a new car. Otherwise, yeah, this is a great car." A great car, indeed. Everyone loves spending time with the GTI. It's got plenty of power, it's quiet, it's comfortable, and it eats up highway miles. We've got just over 10,000 miles on the odometer as of this writing, and as summer carries on, many editors have requested extended periods of seat time in the GTI for weekend getaways and longer road trips. But it's still not perfect. Following the A/C fiasco, there's another, more curious problem plaguing the GTI. Every time the car starts, a weird, varied-tempo, loud clicking is heard from the dash. We think it's coming from the direction of the glovebox, and it's not the same click patten every time. Sometimes it's one or two knocks, sometimes it's several. See what I mean in the video below. Weird, right? Another trip to Suburban Volkswagen offered no help.

Carmakers ask Trump to revisit fuel efficiency rules

Car companies operating in the US are required to meet stringent fuel efficiency standards (a fleet average of 54.5MPG) through 2025, but they're hoping to loosen things now that President Trump is in town. Leaders from Fiat Chrysler, Ford, GM, Honda, Hyundai, Nissan, Toyota and VW have sent a letter to Trump asking him to rethink the Obama administration's choice to lock in efficiency guidelines for the next several years. The car makers want to revisit the midterm review for the 2025 commitment in hopes of loosening the demands. They claim that the tougher requirements raise costs, don't match public buying habits and will supposedly put "as many a million" jobs up in the air. The Trump administration hasn't specifically responded to the letter, although Environmental Protection Agency nominee Scott Pruitt had said he would return to the Obama-era decision. The automakers' argument doesn't entirely hold up. While the EPA did estimate that the US would fall short of efficiency goals due to a shift toward SUVs and trucks, the job claims are questionable. Why would making more fuel efficient vehicles necessarily cost jobs instead of pushing companies to do better? As it is, even a successful attempt to loosen guidelines may only have a limited effect. All of the brands mentioned here are pushing for greater mainstream adoption of electric vehicles within the next few years -- they may meet the Obama administration's expectations just by shifting more drivers away from gas power.
