Abstract
A start control apparatus of an internal combustion engine includes: a gas sensor configured to detect a gas concentration of the liquefied gas fuel in a gasified state at a position near a combustion chamber; a scavenging pump configured to perform scavenging from a position upstream of the combustion chamber to a position downstream of the combustion chamber; and a control unit configured to prohibit a start of the internal combustion engine and operate the scavenging pump when the gas concentration detected by the gas sensor before the start of the internal combustion engine is equal to or greater than a predetermined threshold value.
