Abstract: The fuel specification of methanol mixed with a small amount of gasoline is known to be effective for Otto-type methanol engines for improved cold startability and other benefits.
燃料规格的甲醇混合少量的汽油是已知Otto-type甲醇发动机有效改善冷startability和其它好处。
In consideration of the importance of a fuel specification common to both Otto-type and Diesel-type methanol engines for practical use of methanol, effects of the use of near-neat methanol on engine performance and NOx emission characteristics were studied using heavy-duty direct-injection methanol engines. The results obtained on direct-injection

spark-ignited methanol engines fueled with M85 are as follows: (1) The inlet temperature to the catalytic converter must be raised through intake throttling or by other means. (2) NOx emissions are lower mainly due to the flame temperature of methanol which is lower than that of diesel oil. (3) The exhaust gas recirculation is effective for NOx reduction. (4) At the same level of NOx emissions, the brake thermal efficiency with methanol is lower at low loads but higher at high loads than that with diesel oil. (5) A high ignition stability is achieved over a wide operational range. Number of references: 4

-------------------------------------------------------------------------------- Conversion of methanol to gasoline Abstract
This invention relates to a process for converting alkoxy compounds into hydrocarbon compounds, mostly in the gasoline boiling range. This process proceeds with low heat exchange duty requirements for heating the alkoxy compounds and recycle streams used as feedstocks and for final cooling of reaction product gases for recovery of hydrocarbon product while at the same time offering an improved choice of operating conditions. As may be desired, steam may be added to obtain a desired final steam partial pressure in all catalyst contacts with the alkoxy compounds.
