> Petrol cars aren't that bad especially when only idling for the airco. Diesels are disgusting idling. Petrol cars do not do complete combustion and emit carbon monoxide which is toxic. Diesels don't. Modern diesels, running on mandated low sulfur fuel, can have lower levels of troublesome emissions than petrol cars. Trucks are a different matter though as they generally are not subject to the same emission standards at present.

I drive what, at the time, was being sold as the cleanest diesel engine ever. A super efficient VW which could do 33km for 1 liter of fuel. All lies it turns out. You can smell it easily whilst idling on a warm day with low wind.. and it smells really bad.

  Right I own that car and you are right its claimed emissions were a lie. I now have the fix and it complies with emissions regulations, and gets the same mileage as before. It was stupid of management and engineers to try to defeat emissions tests because clearly they were capable of delivering the car they promised using the engineering skills they had. Being dumb cost them billions of dollars and has nearly destroyed the company, a fine company. Someone just didn't want to do things right at the time and maybe got off on scamming. Current status is that this car has unbelievably low emissions and gets astonishing mileage and also has high performance. Only problem is service costs a lot and requires specialized technicians. I hear Teslas and Apple products have a similar issue. > I can smell it Mine has no smell before or after the fix. I can smell petrol exhaust.

    I formerly leased one before the fix. I thought it was 5-10% mpg reduction?

While diesel fuel combustion engines produce lower levels of carbon monoxide than gasoline engines, these emissions can still generate lethal amounts of carbon monoxide given a sufficient amount of time in an enclosed space. Carbon monoxide makes up anywhere from 2% to 12% of diesel exhaust gases. https://www.dieselinjurylaw.com/carbon-monoxide-poisoning https://www.dieselinjurylaw.com/carbon-monoxide-poisoning

  That's total nonsense. Diesel has max 1%, and that itself is rare. Yes you can produce CO if you deliberately mistune the engine to extreme amounts. Do you know why diesel generators are used in mines? Do you know why there are so many diesel submarines? The answer to both is no carbon monoxide. Because CO in exhaust in a submarine or mine is a very big problem. Your insane lawyer source are insane lawyers. What they say is absolute bullshit. They are ignorant technologically incompetent liars to claim that is the range in any way shape or form for any diesel engine operating in any normal capacity.

      > do try to behave Wow, what insufferable arrogance obnoxiously delivered. Nothing I said was jerky. You seem to be projecting. From your first reference: > an extensive literature review produced no scientifically reported cases of fatal CO poisoning attributed to diesel fuel exhaust. Petrol engines produce 12% CO. Diesel engines simply do not do so, contrary to the claims of the ethically challenged injury lawyer source you provided as your primary reference in your earlier post. Can Diesel produce high CO levels? Yes, but it is hard to force this. The Nazis used diesel to asphyxiate Jews with CO, but they had to meddle with the engines. Submarines and mines. How does anyone survive there in the presence of diesel combustion engines. 1955 study of relative emissions of diesel, gasoline, and propane engines: https://www.tandfonline.com/doi/pdf/10.1080/00966665.1955.10467686 https://www.tandfonline.com/doi/pdf/10.1080/00966665.1955.10... Note in particular the charts beginning on page 105. > exhaust gases from Diesel engines contained less than 0.1% carbon monoxide, whereas the carbon monoxide concentrations in the exhausts of the carbureted engines ranged from 1.5 to 12%. The reason for this difference is the well-known fact that carbureted engines generally operate with a deficiency of air whereas Diesel engines always operate with a substantial excess of air It's basic science that has been known for a very very long time. What you are claiming is wrong and has never been known to be the truth by anyone qualified to discuss this matter. Tell you what. I bet you $1 million USD that you are wrong and that a normal diesel engine produces vastly less than 12% CO emissions. We each put our funds with a third party broker, we have an independent party do the testing, and winner takes all. Do you consent? If you would prefer a different wager amount, so state. Funds to be transferred to the third party broker by each of us in advance of testing. You're a well known famous billionaire guy so this will be peanuts with a guaranteed payoff for you if you really believe your claims.
