甲醇裂解气是甲醇在一定温度下发生裂解反应的产物;液体甲醇蒸发为甲醇蒸汽以及甲醇蒸汽进一步裂解为甲醇裂解气所需的热量全部由排气余热提供。汽油中掺入甲醇裂解气后,发动机可在稀薄混合气下运行,其热效率比汽油燃料高。由于混合气的快速燃烧,使燃烧过程的循环变动下降,燃烧滞后期和燃烧持续期都大为缩短。 Methanol cracked gas is the product of the cracking reaction of methanol at a certain temperature; the heat required for liquid methanol vaporization to methanol vapor and methanol vapor to be further cracked into methanol pyrolysis gas is all provided by exhaust heat. Gasoline mixed with methanol cracked gas, the engine can run in a lean mixture, the thermal efficiency of gasoline fuel than high. Due to the rapid combustion of the mixture, the cycle of the combustion process is reduced, and the lag of combustion and the duration of combustion are greatly shortened.
