When humans burn hydrocarbons, or fossil fuels, the carbon reacts with oxygen.

When hydrocarbon - based fuels like methane are burned in normal air, nitrogen gets mixed in with the combustion product — flue gases from conventional gas power stations contain as little as 3 percent CO2 — which makes scrubbing carbon from power plant emissions difficult and expensive.

The second cause of bad gas is oxidation — some of the hydrocarbons in the fuel react with oxygen to produce new compounds, almost all of them worse than what you started with.

Using CVVT on both camshafts has several advantages when compared with using it just on the intake camshaft, including a two percent improvement in performance (increased volumetric efficiency), two percent improvement in fuel economy (reduced pumping loss) and a 30 percent reduction in hydrocarbon emissions.

It is obvious if we could work with a single hydrocarbon or at the worst a comparatively simple mixture of hydrocarbons, there would be a far greater opportunity of maintaining conditions for combustion that would yield a much larger percentage of useful energy as the fuel is consumed.
