摘要

An excess air factor control device for an alcohol reformed gas engine comprises a primary air valve, a reformed gas supply device interlocked with the primary air valve, a primary air flow meter for measuring primary air flow rate, a gas flow meter for measuring reformed gas flow rate, a secondary air valve for a secondary air controlled by the reformed gas flow rate and an alcohol adding device controlled by the primary air flow rate and reformed gas flow rate, thereby supplying alcohol to the engine when the supply of the reformed gas becomes little or is stopped.
