FLOW-VISIBILITY DEVICE FOR KNOWING WATER COOLING ENGINE PERFORMANCE

摘要

An object of the present invention is to provide a flow visualization method and apparatus therefor capable of accurately grasping the flow characteristics and the amount of cooling water in each part of the water jacket.;The flow visualization method of the present invention for achieving the above object comprises the steps of circulating a water jacket of the cylinder head with cooling water containing small particles that block the light beam; Counting the number of times the small particles block light by irradiating light to the circulating cooling water; Integrating the counting number to convert to the amount of cooling water; and the device therefor comprises a cylinder head for cutting the cooling water water jacket horizontally; A transparent plate covering the upper part of the cut cylinder head to be hermetically sealed; light blocking particles having a small diameter contained in the cooling water circulating in the water jacket of the cylinder head; and installed on the transparent plate to irradiate light into the water jacket. A counter for integrating the number of times of light blocking by light blocking particles flowing along the flow of the cooling water; an electronic control unit for converting the amount of cooling water passing per unit time from the integration signal of the counter; and displaying the amount of cooling water; An indicator; Characterized in that consists of.
