WebThe Inc omplete Combustion of Natural Gas - Methane. Incomplete combustion means burning in a lack of air ( not enough oxygen ). If there is not enough oxygen available for all the carbon to turn into carbon dioxide (see complete combustion ), then some or all of the carbon turns to carbon monoxide. This happens with any hydrocarbon. WebDec 14, 2024 · When methanol is used as a partial alternative fuel, the demand for oxygen in the combustion chamber is reduced due to the lower stoichiometric air/fuel ratio and C/H ratio of methanol, which is beneficial to prevent in-cylinder fuel-rich zones and alleviates incomplete combustion.
