The present invention relates to a purifying device for cleaning the nozzle of combustion chamber of car engine and carbon accumulated in the valve, which is to use an inlet tube connecting fuel oil pump of car for feeding fuel oil into a provision oil reservoir and mixing with an additive. An oil pump of the present invention is connected with the car power supply and starting oil pump, and a solution of oil and additive extracted from the oil reservoir are fed into an oil spraying system by a filter for cleaning the nozzle and valve. The oil spraying system has an oil return tube for returning a part of the oil back into the provision oil reservoir for cycling use. The operation of the present invention is conducted when the car is operating so oil fed by the car oil pump will fill up the provision oil reservoir and will return to the oil reservoir through the oil return tube after the switchover of oil pressure controller so as to achieve the purpose of purifying the engine combustion chamber without affecting normal operation of car.
