Diesels Meet Standards: Celebrations Not Required
Euro diesels actually have low emissions according to a new study from the European Automobile Manufacturers’ Association (ACEA), which studied approximately 270 new diesel vehicles and checked them against the Euro 6d-TEMP standards. Not only did the study show that these vehicles have NOx emissions well below that required by the real driving emissions (RDE) test that came into effect in September 2017, but many of them met the NOx requirements that will go into effect in January 2020.
ADAC, the German automobile club, has calculated that there are more than 1,200 RDE-complaint diesel vehicles available today.
1. It so happens that Europeans are buying fewer and fewer diesels. According to research by Inovev, “Sales of diesel cars in Europe (the world’s most diesel prone continent) fell by 16% in the first half of 2018, to 3.12 million units, a 36.5% market share (down 6 points compared to the first half of 2017).” What’s more, Inovev estimates that the share of market for diesels will be 25% in 2020, 15% in 2025 and 5% in 2030.
2. Arguably, pre-Dieselgate there were plenty of vehicles that could—actually or potentially, given the adequate emissions controls—meet the air quality requirements. It wasn’t the diesel engine itself, it was the group of executives who decided to fudge the numbers and consequently have caused the diesel engine to be looked upon as something that people really might not want to have in their driveways.
GM gives its mid-size pickup customers what they’ve been clamoring for, a clean and quiet, high-torque, fuel-efficient diesel.
General Motors is one company that is clearly embracing the diesel engine.
Homogeneous charge compression ignition (HCCI) is a means by which there is combustion of fuel via pressure rather than a spark.
