The most commonly employed systems of classification are those based on analyses that can be performed relatively easily in the laboratory — for example, determining the percentage of volatile matter lost upon heating to about 950 °C (about 1,750 °F) or the amount of heat released during combustion of the coal under standard conditions.
Note: Heat content of combustible energy forms can be expressed in terms of either gross heat content (higher or upper heating value) or net heat content (lower heating value), depending upon whether or not the available heat energy includes or excludes the energy used to vaporize water (contained in the original energy form or created during the combustion process).
One of the ways to deter the formation of NOx during the combustion cycle is to introduce an Exhaust Gas Recirculation (EGR) process.
Also in the expansion phase, in which it fully utilizes its two liters of displacement, it profits from the high compression ratio; the resulting higher level of pressure during combustion further increases the engine's efficiency.

This is because the amount of CO2 released from E85 during combustion is practically identical to the level of carbon dioxide the plants absorbed from the atmosphere through photosynthesis when they were growing.
Abstract - The emissions and ash behaviour during combustion of wood chips, or co-combustion of two solid agricultural fuels (reed canary grass and barley straw) with wood chips, were studied.
The reference to «clean coal» was somewhat unclear in this context, because clean coal refers to attempts to recapture carbon released when coal is burnt or to otherwise reduce coal pollution during the combustion process.
Actually, a very small percentage of the carbon in coal is not oxidized during combustion.

This is bad enough in itself, since water is not noted for its lubrication qualities in an engine, but even worse, that water dissolves any nitrates formed during the combustion process.
Natural gas (NG) is a potential «bridge fuel» during transition to a decarbonized energy system: It emits less carbon dioxide during combustion than other fossil fuels and can be used in many industries.
They compared estimated emissions for shale gas, conventional gas, coal (surface - mined and deep - mined) and diesel oil, taking into account direct emissions of CO2 during combustion, indirect emissions of CO2 necessary to develop and use the energy source and methane emissions, which were converted to equivalent value of CO2 for global warming potential.
Some experts say that coal - fired plants can only become truly clean if the government and industry pump billions of dollars into the technological upgrades required to extract the carbon dioxide gas created during combustion and sequester it semipermanently deep underground.
Primary measures include the use of low NOx burners and burner optimisation techniques to minimise the formation of NOx during combustion.
Cold air intake would increase the mass of air that enters the engine and thus produce more pressure during combustion.
This is, in part, a result of its multi-link design, where the piston connecting rods are almost vertical during the combustion cycle (rather than moving wider laterally, as they would in a traditional crankshaft rotation).
The rickety carbon - neutral status of woody bioenergy has been sold to the public on a deceptively simple principle: Although a tree's carbon is released during combustion to produce energy, there are no net emissions because a new tree will absorb the resulting carbon dioxide.
