Yes you are correct I made a mistake. The hydrocarbons do not break into individual atoms when sprayed in a mist. A more correct explanation would be the ratio of surface area to volume increases greatly thus allowing a higher percentage of the hydrocarbons to be in contact with oxygen thus the LEL is exceeded and self sustaining combustion can be maintained.
Yes, this is all about surface area, rather than volume. think of a cube with a give surface are. Break it up into 27 equilly sized cubes, the total volume has not changed but the surface areas has gone up considerably

ATF and SKO ( Superior Kerosene Oil ) are similar/same in composition except for some added substances in ATF and ATF being cleaner in terms of small particles and debris etc.

ATF storage tanks are very very clean. Refineries make separate pipelines to transport it where as Petrol, Diesel and Kerosene are transported through the same pipeline. There is intermixing between Kerosene and Petrol and Kerosene and Diesel but not between Petrol and Diesel. This tells me that some quantities of Kerosene in either Diesel or Petrol is acceptable but not in case of Petrol and Diesel.

If you put pure Kerosene then the engine will not start as it has a higher flash point. But if there is some petrol in the tank and then Kerosene is filled up it may start as the preheating required for burning of Kerosene is provided by the initial burning of Petrol.

In case someone fills up the tank with lower RON fuel e.g. 89 or 90 and wants to increase the RON then simply fill in little bit of Kerosene in the tank and you are good to go.

Many years/decades ago in Europe it was not uncommon to add a bit of petrol to diesel for cars during the winter. Dieselquality in those days wasnt what it is today and during winter, or to be more precize, at very low temperatures, diesel would start to flake. Adding a bit of petrol would prevent that.

These days with modern diesel and also modern diesel hihg pressure pumps and injectors, all with very precise tolerances, adding petrol to diesel is a no-no.

To your point. Lots of older diesel engines, on canal barges, tugs, tractors etc used to run on kerosene, but used petrol or a mixture of petrol/kerosene to start.

Mixing kerosene with petrol was a common practice before. Excess smoke and smell of kerosene in the smoke was an issue. There are private bus drivers in calicut who mix petrol in diesel also. They say that they get extra punch while doing so.
