PROBLEM TO BE SOLVED: To provide a flushing method of gasoline engine internal parts, which is practicable to a simple work. SOLUTION: The flushing method of the gasoline engine internal parts comprises processes of: connecting an exhaust port 13 of a flushing liquid supply pipe 15 to an opening portion 18 of a gasoline engine 21, wherein the flushing liquid supply pipe 15 is disposed in a flushing liquid storage container 12 filled with flushing liquid, and has the flushing liquid exhaust port 13 at an end and provided with a gas supply port 14 in the middle, while the gasoline engine has an intake pipe 19 provided with the opening portion 18 on a downstream part of a throttle valve installation part 16; operating the engine to produce a reduced pressure condition in the intake pipe and continuously supply the flushing liquid from the container 12 in a droplet state into the intake pipe of the reduced pressure condition through the flushing liquid exhaust port 13 and at the same time continuously supplying gas of an oxygen concentration below 20 volume% from the gas supply port 14 of the flushing liquid supply pipe 15 into the intake pipe to cause the gas to convey and supply the droplets to the inside of the engine, and to let the droplets contact with the engine internal parts for flushing the internal parts; and discharging the flushing liquid brought into contact with the internal parts.
