Abstract

The present application discloses a scavenging control method and device for a hydrogen internal combustion engine, an electronic device, and a storage medium. The scavenging control method for a hydrogen internal combustion engine includes: acquiring a first moisture content of gas in an exhaust system of the hydrogen internal combustion engine when the hydrogen internal combustion engine is in a stalling state; controlling the hydrogen internal combustion engine to perform a first scavenging operation, if the first moisture content of gas is larger than or equal to a first preset value; and returning to the acquiring the first moisture content of gas in the exhaust system of the hydrogen internal combustion engine, in response to the duration of the first scavenging operation reaching a first preset duration. The scavenging control method for a hydrogen internal combustion engine can reduce the moisture content of gas in the hydrogen internal combustion engine to a level that meets rust prevention requirements through the scavenging operation, thereby significantly reducing the probability of rusting, and keeping the moisture content of gas in the hydrogen internal combustion engine at a relatively low level, so that the hydrogen internal combustion engine is kept in a good working state, and the service life of the hydrogen internal combustion engine is extended.
