<p>The present invention relates to a method for testing low-temperature fluidity performance of a structure consisting of an automobile fuel heater combined with an automobile filter, which applies test voltage to a heater of a fuel filter to analyze the flow of cooled test fluid to be transmitted to a real time control device in real time and capable of being measured and managed. The method comprises: a first step of checking a defect and status information of equipment; a second step of setting fuel pressure, fuel flow rate, cooling temperature, and cooling time; a third step of finishing preparation for supplying test oil to the inside of a chamber; a fourth step of setting and adjusting a filter outlet flow rate; a fifth step of carrying out a cooling process of test oil; and a sixth step of checking time of a point wherein a filter is ruptured due to a test, temperature difference between an inlet and an outlet, a heater current, and power consumption.</p> |
