（1）逐缸切削油：逐缸方法用于確定噴砂缸的位置。如果將油切到某個氣缸，聲音會大大降低或消失，并且在恢復供油時可以清晰聽到。“喀噠”聲表示氣缸活塞撞擊氣缸。
(1) Cylinder by cylinder cutting oil: the cylinder by cylinder method is used to determine the position of the sandblasting cylinder. If the oil is cut to a certain cylinder, the sound will be greatly reduced or disappeared, and can be heard clearly when the oil supply is restored“ The "click" sound indicates that the cylinder piston hits the cylinder.
（2）為了進一步確認氣缸的活塞已被撞到，可以將氣缸的噴油器取下，可以向氣缸中添加少量的CD級增壓油（密封），并安裝一個噴油器，然后引擎啟動。敲擊聲消失或減弱。手術后，再次發生爆震，毫無疑問，它敲擊了氣缸的活塞。
(2) In order to further confirm that the piston of the cylinder has been hit, the injector of the cylinder can be removed, a small amount of CD grade booster oil (seal) can be added to the cylinder, and an injector can be installed, and then the engine starts. The knocking sound disappears or weakens. After the operation, there was another knock, which undoubtedly knocked on the piston of the cylinder.

對于活塞缸，可以使用以下方法：
For piston cylinders, the following methods can be used:
（1）發動機啟動后，發動機會在低溫下發出爆震聲。溫度恢復正常后，聲音消失，無需進一步處理即可暫時進行處理。
(1) After the engine is started, the engine will knock at low temperature. After the temperature returns to normal, the sound disappears and can be processed temporarily without further processing.
（2）發動機溫度正常時，有明顯的爆震聲。盡量避免高速操作，拆卸和維護。
(2) When the engine temperature is normal, there is obvious knock sound. Avoid high speed operation, disassembly and maintenance as far as possible.
（3）拆下氣缸蓋并拔出活塞后，發現氣缸嚴重脫離或變形，或活塞與氣缸之間的間隙太大，應更換氣缸套，活塞和活塞環。
(3) After removing the cylinder head and pulling out the piston, it is found that the cylinder is seriously separated or deformed, or the gap between the piston and the cylinder is too large. The cylinder liner, piston and piston ring should be replaced.
（4）如果發現連桿變形，則應盡可能更換。
(4) If the connecting rod is found to be deformed, replace it as far as possible.
