The invention relates to a device and method for measuring the engine ignition advance angle. The device comprises a dynamometer for testing performance indexes of a to-be-tested engine, and also comprises a controller, an igniter, a piston displacement detector, and a crankshaft angular displacement detector, and the controller is electrically connected with the igniter, the piston displacement detector, and the crankshaft angular displacement detector. The igniter is electrically connected with a spark plug of the to-be-tested engine, and the spark plug corresponds to a spark plug mounting hole of the to-be-tested engine and is used for igniting the to-be-tested engine after receiving an ignition signal. The piston displacement detector corresponds to the spark plug mounting hole of the to-be-tested engine and is used for detecting piston displacement of the to-be-tested engine and sending a piston displacement signal to the controller; the crankshaft angular displacement detector is used for detecting the
