The invention relates to a vehicle-mounted carbon-free fuel mixing proportional valve with a preheating function, and belongs to the technical field of new energy automobile fuel cells. According to the technical key points, the front valve component comprises a front valve body and an ammonia water valve; an upper fluid cavity, a lower fluid cavity and a confluence cavity are formed in the front valve body; the upper fluid cavity and the lower fluid cavity are arranged in parallel up and down; the rear valve component comprises a rear valve body and a main valve; a protruding part is arranged at the left end of the rear valve body, and external threads are arranged on the outer surface of the protruding part. The protruding part of the rear valve body is in threaded connection with the interior of the inserting opening of the front valve body, and the confluence cavity is correspondingly communicated with the flowing hole channel. By adopting the scheme provided by the invention, the hydrogen fuel cell can be started more quickly in a low-temperature environment, and the cold start time is shortened.
