第2858期:Death of diesel
Episode 1
We're talking about the future of diesel. Richard, does diesel have a future? Yes and no. It certainly doesn't if you live in the city, because many cities are banning diesel cars in the near future.我们来谈谈柴油车的未来。Richard，柴油车还有未来吗？有，也没有。如果你住在城市里，那基本上是没有的，因为很多城市将在不久的将来禁止柴油车。
Paris, for example. IncludingParisand a number of other cities are considering it, yes. And also, Volvo have recently announced that all their vehicles will be electric or hybrid from 2019.比如巴黎。是的，包括巴黎在内的许多城市都在考虑禁用柴油车。此外，沃尔沃最近宣布，自2019年起，他们所有的车辆将是电动车或混合动力车。
So you mean they're going to stop making diesel vehicles? Yes. So why is there such a negative attitude now towards diesel? Well, it all stems from the VW emissions scandal a few years ago. Which we did a podcast about.所以你的意思是他们要停止生产柴油车？是的。那么为什么现在对柴油会有如此负面的态度呢？这全部源于几年前大众汽车的排放造假丑闻。我们当时还为此做过一期播客。
We did. Briefly, VW were making their car so they could fake the results for testing. And they found that their diesel cars were much more polluting than advertised.确实做过。简单来说，大众制造汽车时让它们能够在测试中作弊。而事实证明，他们的柴油车比宣传的污染严重得多。
OK, so they were making it look like diesel cars were a good thing to buy, but in fact they weren't. Exactly. But Richard, even before that scandal, diesel was always promoted as a good environmental option.好的，所以他们让柴油车看起来像是很好的选择，但实际上并不是。没错。不过 Richard，即使在那场丑闻之前，柴油车一直被宣传成环保的选择。
Yes. And that stems from the difference between the petrol engine and the diesel engine. Right.是的。这源自汽油发动机和柴油发动机之间的差异。确实。
Which is? Well, diesels are actually more efficient than petrol engines and they produce less carbon dioxide. OK.那是什么差异？柴油发动机实际上比汽油发动机更高效，并且产生的二氧化碳更少。好的。
However, more recently they've found that they produce more nitrogen dioxide, which is bad for the health, and more particulate matter, basically stuff, fumes, which can cause cancer.然而，近年来人们发现柴油车会排放更多的二氧化氮，这对健康有害，同时也会产生更多颗粒物，就是那些可能致癌的烟雾。
And those are worse than CO2 emissions, are they? They're certainly worse for your immediate health. Right. Yes.这些排放比二氧化碳更糟吗？它们确实对人的直接健康危害更大。是的，没错。
