| description | The invention discloses a cold start test method and a cold start test device for a dual-mass flywheel engine. The cold start test method comprises the following steps: a single-mass flywheel engine and a starter are placed in a cold start environment; the starter is started, and the highest rotating speed of the single-mass flywheel engine, the current of the starter and the voltage of the starter in the process that the starter drags the single-mass flywheel engine are collected; the rotating speed of the dual-mass flywheel engine is obtained according to the preset torque deviation of the dual-mass flywheel engine, the highest rotating speed of the single-mass flywheel engine, the current of the starter and the voltage of the starter; whether the rotating speed of the dual-mass flywheel engine is lower than a rotating speed threshold value or not is judged; and if yes, the cold start test of the dual-mass flywheel engine passes. According to the method, the cold starting resistance torque and the rotating |
