particulates
Oxygen and petrol or diesel is burned in a car engine, it is not formed
Soot particles are the result of incomplete combustion of carbon or organic compounds.
Your question assumes that it is more likely for this to happen in engines. It is NOT more likely. Burning a fuel anywhere produces carbon dioxide. The formation of the carbon particles depends on the amount of oxygen available and the tepmerature of combustion.
sulphur dioxide is formed from sulphur compounds when petrol is burned
When the DMAX company was formed, they began designing engines. The first Duramax engines were produced in the late 1990's. The 6.6L Duramax Turbodiesel V8 was invented in 1999, and came out in year 2000 GM heavy-duty pickup trucks.
When hydrogen is burned, water vapor is formed. During running this will be blown out of the exhaust, but when the engine is stopped some will no doubt condense, so could corrode steel in the engine. But it is less likely than for a gasoline engine where other combustion products like nitrogen oxides are also formed, and these are more corrosive. I have no direct experience but hydrogen engines are said to be much cleaner than gas or diesel ones
The material formed is Carbon.
Atom is formed of electrons, protons and neutrons.
energy for electronics
New molecules are formed.
Co2 + h2O
Cooper get oxidised to copper oxide when burned in air.
