Abstract
A gas supply device is equipped with an oxygen enrichment membrane module, a pump portion, and an electronic control unit. The electronic control unit performs oxygen enrichment control for merging the air supplied to a first space from a second space through the oxygen enrichment membrane and containing a higher concentration of oxygen than an atmosphere with the atmosphere that has flowed into the first space and supplying the merged air and atmosphere to a combustion chamber of the cylinders by driving the pump portion, and nitrogen enrichment control for discharging air containing a higher concentration of oxygen than the atmosphere to the second space from the first space through the oxygen enrichment membrane, producing air containing a higher concentration of nitrogen than the atmosphere in the first space, and supplying the air containing the higher concentration of nitrogen to the combustion chamber by driving the pump portion.
