How does ProFuelX-2©® decrease smoke and particulate emissions and reduce noise in diesel engines?
In diesel engines, during the compression stroke only air is compressed and it heats up above the self-ignition temperature of diesel fuel. Near the end of compression stroke, liquid fuel is injected as very fine droplets, where it mixes with hot air. After a brief period called Ignition Delay, the fuel-air mixture ignites causing a rapid rise in pressure and temperature. This is called Premixed Burning Phase, where the bulk of NOx emissions and noise are produced. The rest of the diesel fuel is burned in the Diffusion Burning Phase where the rate of burning is controlled by air-fuel mixing, time and temperature. Diesel soot (unburned carbon particles) is formed in this phase. Most of the soot that is formed is subsequently burned during the later portion of the expansion stroke.
