In figure 14, combustion efficiencies of three stratification cases are plotted against maximum in-cylinder pressure rise rate.
At the same CA50, the strong stratification case has longer BURN 10-90 and lower maximum in-cylinder pressure rise rate in comparison to the homogeneous case.
This section evaluates the effect of the thermal stratification with "dual intake ports stratification" under the high engine speed condition.
In order to consider the reason why the effect of the thermal stratification with "dual intake ports stratification" decreases under the high engine speed condition, the difference in in-cylinder temperature between the probes A and B, which probes are shown in figure 4, is compared in figure 23.
For further research of the reason why the thermal stratification with "dual intake ports stratification" is less effective under the high engine speed condition, ignition delay was computed by CHEMKIN-PRO [9].
The effect of the thermal and equivalence ratio stratification was computed with 3D CFD coupled with chemical kinetics calculation.
After 3 mo of cold stratification at 5 C followed by seed transference at 15/4 C (Treatment A), mean embryo length was 3.
EFFECT OF COLD STRATIFICATION TREATMENTS, ILLUMINATION CONDITIONS AND SEED AGE ON SEED GERMINATION
Final germination rate increased when the stratification period was extended to 4 mo in combination with low or middle incubation temperatures (5, 15/4, 20/7 C; Fig.
Germination percentages were higher in seeds incubated in darkness than in the light, and cold stratification in darkness was also more effective in breaking dormancy than when performed in the light (Fig.
EFFECT ON SEED GERMINATION OF WARM STRATIFICATION PRECEDING COLD STRATIFICATION
Compared to cold stratification for 4 mo at 5, 9/5, or 10 C, stratification of freshly matured seeds at autumn temperatures (1 mo at 20/7 C [right arrow] 1 mo at 15/4 C) preceding 2 mo of cold stratification at 5 C (Treatment D) showed a beneficial effect on percentage germination when seeds were incubated at 15/4 C, irrespective of light conditions during stratification or the incubation phase.
