The invention discloses an automobile fuel
economizer, belongs to the technical field of automobile fuel economizing devices, and mainly solves the problem that existing automobile fuel and
exhaust emission are not low. The automobile fuel
economizer is mainly characterized in that an
oxygen-
hydrogen gas generation device comprises a shell, a positive
electrode plate, a negative
electrode plate, a liquid outlet, a sealing pad, a gas outlet, a filling hole and a protection cover of an end opening of the shell, the positive
electrode plate and the negative electrode plate are arranged in the shell, the liquid outlet is formed in the bottom of the shell, the sealing pad is positioned at an end opening of the shell, a positive electrode electrolytic column and a negative electrode electrolytic column are arranged on the protection cover, a high-
voltage pulse generator is a 12V or 24V vehicular high-
voltage pulse generator, an output end of the high-
voltage pulse generator is respectively connected with the positive electrode electrolytic column and the negative electrode electrolytic column, an
oxygen-
hydrogen gas filtering device comprises a vertical closed shell, an air outlet, an air inlet, a water outlet, an upper fixing support and a lower fixing support, the air outlet is formed in the top of the closed shell, the air inlet and the water outlet are formed in the bottom of the closed shell, the upper fixing support and the lower fixing support are arranged on the side of the closed shell, and the air outlet is connected with the air inlet through a pipeline. The automobile fuel
economizer has the advantages that automobile fuel is saved,
exhaust emission is decreased, and a PM2.5 value is reduced.
