This re-combustion control means for an alcohol engine comprises intake (6) and exhaust valves (7) designed to be opened or closed by virtue of magnetic force that are disposed, respectively, in intake and exhaust ports (16,17) of cylinders (1,2,3,4), control valves (8) designed to be opened or closed by virtue of magnetic force that are disposed, respectively, in combustion gas ports (18) communicating with each other via a combustion gas passageway (11), sensors (14) for detecting a state in which the engine is operated, and a controller (10), for controlling the supply of combustion gas from predetermined cylinders (1,4) to the other cylinders (2,3) via the combustion gas passageway (11) in response to a detection signal detected by the sensors (14). In response to a signal informing that the engine is under partial load, the exhaust valves (7) of the predetermined cylinders (1,4) are maintained in a closed state with the control valves (8) thereof being operated so as to be opened or closed, while the intake valves (6) of the other cylinders (2,3) are maintained in a closed state with the control valves thereof being operated so as to be opened or closed so that combustion gas produced in the predetermined cylinders (1,4) is taken into the other cylinders (2,3) and is reburned therein for complete combustion, the discharge of unburnt aldehyde or the like being thereby prevented. |
