fuel-air mixture

fuel-air mixture

The fuel-air mixture denotes a combination of fuel and air within a certain range of proportion. It is chemically correct when there is enough air in the mixture to burn up the present fuel completely. Normally, it is 1:15 by weight. There are three types of fuel-air mixtures: normal, lean, and rich.

This condition, if not detected and corrected, combined with an inoperative fuel tank inerting system, could lead to an uncontrolled overheat of the hydraulic fluid, possibly resulting in ignition of the fuel-air mixture.
In the cylinder there is an accelerating process of combustion of a fuel-air mixture throughout the volume of the combustion chamber.
At temperatures above the reported limits, the ignition energy was still sufficient to ignite the fuel-air mixture and produce small pressure rises from combustion.
The NOx emissions of combustion devices burning fuels that are Nitrogen (N)-free can be formed through the below given mechanisms: a) NOx thermal mechanism dominated by the local temperature of the combustion products; b) the prompt NOx mechanism observed mainly at fuel-rich mixture and unburned fuel-air mixture prior to the arrival of the fore-flame; and c) the [N.

With all valves closed, the piston comes back up, compressing the fuel-air mixture.
As a result, the oxygen molecules penetrate into every molecule of the fuel, which helps complete burning of fuel-air mixture.
In addition the intercooler, which cools the fuel-air mixture and raises air density, has been upgraded from the earlier one-stage type to a two-stage configuration.
The technology compresses the fuel-air mixture to a sufficiently high pressure and temperature that it ignites without spark plugs, similar to a diesel motor.
