Abstract: An apparatus to auto-adding an energy-saving activator has a container and a control unit. The container has a heater electrically connected to a control circuit of the control unit. The control unit has a vibration sensor and a sound sensor. When both the vibration and sound sensors transmit signals, the control circuit will actuate the heater to heat the energy-saving activator in the container so that the heated energy-saving activator turns into vapor and leaks out of the container toward the internal combustion engine to decrease the carbon deposits. Using both the vibration and sound sensors is in order to actuate the heater correctly without erroneous judgment. The heated vapor drafts into the internal combustion engine at once to mix with the fuel so that the fuel is burned oxyfuelly and completely to efficiently decrease the carbon deposits. Therefore, the efficiency of the internal combustion engine is also enhanced.
