Achieving stable complete combustion with retarded ignition timing (15-20[degrees] ATDC).
The other contributing factor for the retarded ignition of the physical property variation case (JetA_chem_S8_phy) was the decreased liquid fuel density.
Because of the retarded ignition, the engine will, of course, produce less power, and have slightly higher fuel consumption.
In other words, if a good burn does not have developed at the first 4 or 5 spark duration degrees, there is no advantage to sustain a spark above this point, because the explosion in question would be with a very retarded ignition point, injuring the engine power.
Nitration of crankcase oil is defined as the saturation of crankcase oil with soluble and non-soluble nitrous bi-products typically related to low cylinder temperatures as a result of better scavenging, leaner mixtures, lighter loads, and retarded ignition timing.
Most engine manufacturers are meeting this challenge with a combination of EGR, retarded ignition tinting, controlled injection rate and higher injection pressures.
Furthermore the influence of the retarded ignition and therefore the reduced combustion efficiency is visible.
The lower temperature and pressure associated with the retarded ignition timing increased the time to auto-ignition by approximately 0.
For WOT operation, retarded ignition was preferred over enrichment as knock mitigating measure.
Starting at very retarded ignition timings, the ST was advanced in order to achieve knocking combustion conditions.
An E10 PFI case at 8 bar IMEP was included to get a smoother trend between IMEP and retarded ignition.
