The Dieselgate Scandal: A Timeline
The Dieselgate scandal began in September 2015, when the US Environmental Protection Agency (EPA) issued a statement alleging that Volkswagen had installed software in its diesel vehicles to cheat on emissions tests.
Key Events
However, the diesel engine has a rich history and has been a staple in the automotive industry for decades. In this article, we will delve into the history of diesel engines, their benefits, and the challenges they face in the modern era.
A Brief History of Diesel Engines
The diesel engine was first patented in 1892 by Rudolf Diesel, a German engineer. Diesel’s design was a significant improvement over the existing steam engines of the time, as it used compression ignition instead of spark ignition.
The diesel market in the U.S. has been virtually nonexistent since the scandal broke.
The Diesel Emissions Scandal
In 2015, Volkswagen, the world’s largest automaker, was caught red-handed in a massive diesel emissions scandal. The company had installed software in its diesel vehicles to cheat on emissions tests, allowing the vehicles to produce up to 40 times more pollutants than allowed by law. This scandal led to a global outcry, and governments around the world responded with stricter emissions regulations and policies to phase out diesel vehicles.
The Impact on the Diesel Market
The diesel market in the U.S. Many major automakers, including Volkswagen, have stopped producing diesel vehicles in the country. The Environmental Protection Agency (EPA) has also implemented stricter emissions standards for diesel vehicles, making it difficult for diesel vehicles to meet the new regulations. Key points to consider:
