| Abstract(E) | The purpose of this study is to clarify the effects of ethanol blending on emissions, thermal efficiency, knocking, and burning velocity in super-lean burn. Engine tests results showed NOx were reduced due to the lower adiabatic flame temperatures. Corrected THC for reduced FID sensitivity of ethanol and aldehydes showed little significant difference. Under high-pressure and high-λ conditions, the 50-90% combustion duration increased, and the calculated laminar burning velocity decreased. This suggests that ethyl radical generation within the flame zone is inhibited, and that the effect of methyl radical recombination reactions may be involved. |
