| Abstract: | The importance of cylinder sealing inspection for improving engine working reliability was analyzed and the principle of inspecting cylinder sealing was introduced.The inspection method of combining the battery-starting power and TDC signal under the conditions of dragging was put forward.The rapid and convenient inspection of cylinder sealing was realized.The results show that the method can position the cylinder with the leakage accurately and has better sensitivity.Accordingly,the method is suitable for the on-line inspection of cylinder sealing. |
