The device is easily operated, conveniently maintained and easily integrated with the automatic control software to realize the automatic control of the whole device.    DETAILED DESCRIPTION - An M15 methanol petrol and M85 methanol petrol blending device has a petrol tube composed of a petrol tank, F101 valve, F102 valve, B104 pump, F103 valve, KV101 mass flow meter, FT101 electric adjusting valve, F104 valve and an F105 valve, and a methanol tube composed of a methanol tank, F201 valve, F202 valve, B102 pump, F203 valve, KV201 mass flow meter, FT201 electric adjusting valve, F204 valve and an F205 valve. An additive tube is composed of an additive tank, F301 valve, B101 pump, F302 valve, KV301 mass flow meter, FT301 electric adjusting valve and an F303 valve. The F105 valve is connected with a TF02 mixing tank, the F205 valve is connected with a TF01 mixing tank, and the F303 valve is connected with the TF01 mixing tank. The TF01 mixing tank is connected with the TF02 mixing tank, and an M15 methanol petrol tank is connected with the TF02 mixing tank through a F405 valve. An M85 methanol petrol tank is connected with the TF02 mixing tank through a F406 valve. The F101 valve is connected with the B102 pump through a F403 valve, and the F201 valve is connected with the B104 pump through a F402 valve. The F104 valve is connected with the TF01 mixing tank through the F403 valve, and the F204 valve is connected with the TF02 mixing tank through a F404 valve. An INDEPENDENT CLAIM is also included for a method for blending M15 methanol petrol and M85 methanol petrol.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a device for blending M15 methanol petrol and M85 methanol petrol. '(Drawing includes non-English language text)'
