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 ESG is activated not to ignite the
spark plug. Therefore, the engine speed varies and is controlled under 6300min
