On SE:Aviation, someone asked why planes don't use gasoline.
A comment below stated following:
A better question is why do cars run on petrol rather than kerosene. – Aron
So, here I am asking the exact same thing.
The primary reason is gasoline is more efficient. It vaporizes easily (below boiling point of water), burns faster and more completely. On top of that, it is cleaner burning than kerosene.
Kerosene is closer to diesel fuel and is less refined. It can withstand higher temperatures before it vaporizes. This means combustion is not as easy as it is with gasoline.
Reference; "What's the difference between gasoline, kerosene, diesel, etc?", 1 April 2000. HowStuffWorks.com
Much of the reason is historic. Back when cars were new Gasoline was actually a by-product of kerosene production from petroleum. Kerosene was a much more valuable commodity at the time because it was widely used for lighting, so nobody wanted to use it for transportation. Gasoline was marketed as an auto fuel by the oil companies mainly to find a use for it, and it turned out to be a good choice because at the time the technology favored lighter fuels. Gasoline became popular, and that led gasoline overshadowing kerosene as the primary use of oil. Thermal cracking was developed to produce more gasoline from crude oil, enabling the automobile industry to keep expanding.
Engines can run on Kerosene,But cold starting is a problem, as vaporisation is not as good (I have used it many times in Landrovers on the farm). Furguson tractors used Petrol for warm up then switched to Kerosene with no ill affects. However due to the poorer vaporisation, timing must be altered and performance is reduced
The reason is diesel can burn after compression or alone. This feature is absent in the case of kerosene. So, this is the best possible reason of not using kerosene as a fuel. Lubricity is definitely lower, as is energy value (especially in summer).
It would work fine in diesel, if 2-stroke oil is added to get the lubricity up.
Engines (and jet turbines respectively) have been optimized for a fuel (gasoline, diesel or kerosene respectively) and vice versa. If turbines ran better on a "slightly different" kerosene then kerosene would be produced "slightly different". If turbines could be build to run better with the available kerosene, the changes would be introduced (assuming they are technical/economical viable).
So cars run on their respective fuels, because kerosene is a bad choice for their types of engines. And the types of engines are good choices for the size/weight/power/price/... requirements of a car. You could build a turbine powered car and fuel it with kerosene. The result is something like this:
You could set a speed record, but don't even think about trying to park (let alone drive) it in the city...
P.S.: I noticed, jet engines on cars are "more widely" spread than I'm implying above: https://en.wikipedia.org/wiki/Jet_car
Here were I live some people do run their petrol/gas cars with kerosene; their engines are old ones tho, American cars from the 50's and soviet Ladas and Moskvich from the 60's. What they do is to pre-heat the kerosene before entering the engine, an artifact between the carburetor and the intake manifold. When the kerosene goes through it, it get vaporized and then the engine can run. They also need to change the timing. These cars works "fairly enough" well with kerosene, you can smell them differently, and they just run...however their power and pickup get very affected negatively.
