I’m not a car guy and I really can’t even tell if you responded to the right comment or if it just makes so little sense to me I wouldn’t know either way.
I’m not a car guy, but I am the son of one and have plenty of gear head friends. DPF is Diesel Particulate Filter. It basically catches all the soot and then, when it’s full enough, and the DPF is hot enough, there is a fuel injector that injects fuel and burns it all out. That’s called a regen. When see white smoke, that’s probably what you are seeing. If the DPF gets clogged, the engine won’t start as it can’t exaughst. So being able to regen is important. To get up to temperature to regen, the diesel needs to be run hard for about 10-15 minutes. Which it will get on a decent speed trip. DPFs came in to make diesels less dirty. Though you can argue it’s moving the problem as much as reducing it. It’s illegal but common, to bypass DPFs when it starts being an issue.
I know all this because it was the DPF that killed my last diesel.
Very widely held view that diesels were more reliable without DPFs. That they aren’t good for the mileage they were pre-DPFs. Of course they were also even dirtier.
“They don’t make them like they used to.”
Yeah dad, you are right. You are far less likely to die.
Fatal crashes have actually gone up in recent years. Likely due to an uptick in SUVs and pick up trucks with their huge blind spots
There are less crashes now overall but they are far more deadly.
Its under 5 falaties per 100K in most of europe. Norway at 2. Monaco at 0 (but foes that count?)
Russia is at 11.
Usa is at 13.
Really not true about diesels. DPF is a common problem but didn’t even exist in early diesels. Mechanics hate DPFs. Maybe true about petrols.
But EV are better still (if you can have a home charger) and weren’t really a thing in the 80s/90s. Bar milk floats.
