Document Type and Number:
Japanese Patent JP2832031
Kind Code:
B2
Abstract:
A method and an apparatus for protecting an engine from damage due to such factors as piston scuffing and/or knocking. The vibration of the engine is measured and vibrational thresholds indicative of either engine knocking or piston scuffing are generated and the actual engine conditions compared with those criteria. If either knocking or piston scuffing are predicted to occur, protective action is taken by either shutting the engine down, reducing its speed and/or providing additional lubrication for the engine. When protective action is taken, a warning is also given to the operator of a detrimental condition.
