chemical reactions are, you know, controlled by the thermodynamics

If you knew the slightest thing about the problem with ozone destroying
chemicals,
of which the chlorinated freons were prime culprits, you would know that they were a problem

Fossil Fuel is a generic term that isn't quite correct Natural Gasoline is a distilled derivative
of oil but almost all ofit is manufactured from cracked and recombined oil derivativeswhile natural gasoline is further refined intoPropane, butane, Proproline (a plastics feed stock), and Natural gasand also separates out sulfur (for fertilizer and explosives) Gasoline can be made from coal («Coaline») or from organic matter («Bio-fuel») but uses a few
of oil based feed stocks instead tomake «Sythiline» (artificial gasoline) This gasoline is actually cleaner burning then natural gas with allit's «flare offs» (butane, propane, propoline, sulfur) used in theearly 19th century
because it is manufactured only with essentialHydrocarbons Diesel fuel is also becoming more and more Manufactured instead ofdistilled as demand for it rises but improvements in Hydro cleaningis allowing for diesel with no volatile
chemicals like sulfur andmercury (taken out for petro -
chemical feedstock to make fertilizerand thermometers) In both cases what you have is pure hydro - carbons, a carbon atomwith hydrogen atoms attached to it In the case
of gasoline there is CH1, cH7, CH11 When in a combustion engine the gasoline is sprayed into the pistonafter being mixed with air and the drive
of the engine compressesthe the chamber filled with the gasoline mist until it's full downstoke then the spark plug causes the Exothermic
reaction... which isthe conversion
of the potential energy in the gasoline mist to heatand force, with the force side
of that equation shooting the pistonupward and the top
of the stroke kicking what's left
of thecaramelized gasoline mist out into the Emission control box If the Emulsion control box wasn't there to filter out the burntgasoline particles, any potential additives and volatile chemicalsthen the caramelized gunk hitting air would create CARBON MONOXIDEin the cooler then the heat
of the engine difference CARBON MONOXIDE can also become a problem if the Emissions controlBox filter, air filters or muffler filters is worn or damaged.

chemical reactions i.e. feedback as mentioned by a number
of commentators).
