PURPOSE: A pressure regulating valve for an engine test is provided to simplify the preparation of measurement test for a pressure and a flow ratio of oil of an engine oil system which passes through a regulating valve by enabling the setting of an opening side pressure with a control screw screw-coupled with a valve body. CONSTITUTION: A pressure regulating valve for an engine test includes a valve body(12), and a piston(16) connected to a spring(14) mounted in the valve body to be pushed by an oil pressure while compressing the spring, and a control screw(18) connected to the spring at a front end and coupled at a rear end part of the valve body for controlling the compression force of the spring for changing a spring constant.
