Madrid mayor, Manuela Carmena, signed a commitment to rid the pollution-stricken city of diesel-powered cars and trucks by the middle of the next decade.
She joined the mayors of Paris, Athens and Mexico City in signing the deal to improve air quality at the biennial meeting of city leaders in Mexico on Thursday.
She also vowed to continue in a drive for alternative vehicle use and improve conditions for cyclists and pedestrians in the city. …

I'll have to disagree on that. Try running an Otto ("gasoline") engine on diesel fuel or vice-versa. Diesel fuel is the same as heating oil.
It says diesel fuel only on my trucks fuel tank cap.
One is not exclusive of the other as what came first, the chicken or the egg. Typically, it requires an engine designed to take a relatively low point of ignition fuel as kerosene and compress it enough to ignite. It uses no spark plugs or ignition other than what are called glow plugs to heat the fuel in cold weather conditions to enable it to ignite from the normal pressures of the compression cycle.
I suppose you can say it is a process that requires a special engine for a relatively commonplace petroleum product that was far more available before refined gasoline and was far more stable for storage. Its initial heavy uses were for industrial, transportation and farming machinery. Diesel engines typically operate efficiently at low RPM’s and deliver far more torque per HP than gasoline engines and the main reason why it is still preferable to gasoline for heavy trucks and farming.
As for availability, it was preferable during the fuel shortages and the Europeans went hog wild with the technology for smaller engines because refineries can produce far more amounts kerosene per barrel than gasoline as it was commonplace that diesel was much less expensive at the pump.
They can buy NG from Texas. Maybe to,to,reduce smog.
“Diesel fuel” is usually Number 2 fuel oil, which is used in home heating also.
Rudolf Diesel designed his engine to be able to burn a variety of fuels, from vegetable oil to pulverized coal. Hence “diesel-fueled” is still a misnomer.
You’re splitting hairs where it is uncalled for. Just look at the different pumps at your local “gas” station...
Well, I don’t think I’m splitting hairs, since one of the pumps is labeled “kerosene” and another “off-road fuel” (with the red dye); the latter I can use in a diesel engine as I could home heating oil, but it’s technically not “legal” since it’s cheaper out of pocket and I’m not paying all the taxes they want me to pay.
And like I pointed out before, Rudolf Diesel and others (including Detroit Diesel) successfully ran these engines on two-micron coal particles. This did increase internal wear and sludge development, but they did run, notwithstanding.
