The present invention is directed to an apparatus for purging a crank case of a duel fuel engine. The apparatus for purging a crank case of a duel fuel engine in accordance with the present invention can include: a purge gas supply unit configured to supply purge gas for purging an inside of the crank case; a supply line configured to provide a path for supplying the purge gas to the inside of the crank case from the purge gas supply unit; an open/close unit installed in the supply line and configured to open and close supply of the purge gas; and an exhaust line installed in the crank case for exhaustion. The present invention can prevent the fuel gas leaked out from the crank case from exploding by removing the fuel gas present inside the crank case of the duel fuel engine, and furthermore can minimize the efforts and costs for removing the fuel gas by precisely determining whether the fuel gas is present inside the crank case.
