High speed ESG (Electronic Safety Governor)
High speed ESG is a device to prevent over revolution of the engine. If the load to the engine becomes light for
some reason, it runs at a higher speed than the usual. In such the case, the buzzer sounds and the ESG is
activated not to ignite the spark plug, therefore, the engine speed varies and be controlled under 6200 min
(rpm).
Low speed ESG
Low speed ESG is a device to prevent the engine from getting damage. If the engine has problems regarding
cooling water, oil pressure, and sensors, the low speed ESG is activated not to ignite the spark plug, and disable
fueling therefore, the engine speed varies and be controlled under 3000 min
