It is found through computation and analysis that based on the premise that the structure parameters of the engine has not done adjustment , when the excessive air coefficient is different (the amount of oil supported is same), methanol petrol flame spread speed increases with the increasing mix ratio, power performance gradually reduces with the increasing mix ratio;
when the excessive air coefficient is same (the amount of oil supported is different), methanol petrol flame spread speed gradually reduces with the increasing mix ratio, engine temperature and burning emission heat gradually increases with the increasing mix ratio, power performance slightly drops with the increasing mix ratio at the same time.
Influence of ethanol and methanol gasoline blends on the mutagenicity of particulate exhaust extracts
Influence of compositions of modified blends of polyamide/poly(vinyl alcohol) on the methanol/gasoline fuel barrier properties o
The MPVA and MPA hot-pressed sheets exhibit the best and worst methanol/gasoline fuel permeation resistance among these modified resins, which show much better methanol/gasoline fuel permeation resistance than pure PE resin.
It is worth noting that the methanol/gasoline fuel permeation resistance of MPAPVA sheets improves consistently with their PVA contents.
Similarly, after blending these barrier resins with PE, the methanol/gasoline fuel permeation resistance of the blended bottles improves to become significantly better than that of pure PE bottles.
