Fossil fuel combustion is a primary contributor, but so are biofuels and even the burning of hydrogen.

As might be anticipated, our procedure to model emissions differs for direct residential fuel combustion and electricity.

However, for residential fuel combustion, the uncertainties may be somewhat greater.

The cone is designed to channel fuel combustion into hard-to-reach areas at the top of the cylinder.

Such areas include catalysis and applications in fuel combustion.

Air Force officers said that may have been caused by incomplete fuel combustion, like a backfire in an automobile engine.

Internal combustion engines capture 20-25% of the energy released during fuel combustion.

The remainder comes from fuel combustion in heating and industrial processes.

Water reduces the heat of fuel combustion, causing smoke, harder starting, and reduced power.

During testing of early prototypes, Whittle had run into difficulties with fuel combustion.
