JB cylinder pad ablation reason and maintenance guide

JB cylinder cushion is mainly used to ensure the JB cylinder block with JB cylinder head junction plane between the seal and prevent air leakage, leakage. JB mat direct contact with high temperature and high pressure gas cylinder, so in use is easy to erosion, especially surrounding the crock mouth edge. JB cylinder pad can make the engine work status seriously deteriorated after burning, also easy to cause some related components or parts of the damage. Today, kang kang kang powder and discuss how to determine JB cylinder pad damage and how to solve! , the reason of JB cylinder pad ablation cylinder head bottom flatness error, flatness out-of-tolerance at the top of the cylinder block, cylinder head bolt loosening or tightening torque too big cause untight seal, gas channeling. Improper driving operation method, used to fierce refueling door and urgent acceleration, speed, too much pressure cylinder gasket erosion. Engine often in large load, engine overheating, detonation, such as running, lead to local high temperature and high pressure in cylinder and ablation cylinder pad. Injection timing early; Diesel improper selection; The combustion chamber carbon deposit. Cylinder cushion poor quality, uneven thickness; Uneven, including memory have bubbles, asbestos laid or package is not tight. Fault phenomena, cylinder pad ablation phenomenon: the engine operating in power suddenly fell, the speed significantly reduced; Body shaking, severe and exhaust pipe has minor injustice phenomenon; After the engine flameout start-up difficulties or unstable idle speed. , JB cylinder and cooling waterway between burning phenomenon: when the engine is running, the water temperature rise suddenly, dull and rotational speed, and power down, cooling water consumption too fast; Exhaust pipe is moisture discharge, especially when idle running, the exhaust fumes with pale yellow phenomenon; Higher plane crankcase oil, lubricating oil emulsion is serious; The radiator filler with dirty marks. If the loss is serious, a lot of cooling water will enter the JB cylinder, a surface cannot be started.
