Revolving speed variable voltage power supply for glow plug of two-stroke or four-stroke gasoline engine

A revolving speed variable voltage power supply for a glow plug of a two-stroke or four-stroke gasoline engine, comprising:

• an adjust device configured for outputting different control commands according to different revolving speeds of the two-stroke or four-stroke gasoline engine;
• a switch device connected to the adjust device, and configured for controlling an on-off of a circuit according to the different control commands;
• and
• a rectify device connected to the adjust device and the switch device, and configured for providing different voltages to the glow plug according to the different control commands and/or an on-off of the switch device;
• wherein the adjust device comprises:
• a speed acquisition unit configured for collecting the revolving speeds of the two-stroke or four-stroke gasoline engine;
• and
• a control unit connected to the speed acquisition unit, and configured for outputting the control commands according to the revolving speeds;
• wherein the control unit is further configured for that:
• when the revolving speed falls within a first revolving speed range, the control unit outputs a first control demand to the switch device to control the switch device to be turned on;
• when the revolving speed falls within a second revolving speed range, the control unit outputs a second control demand to the switch device to control the switch device to be turned off;
• and
• when the revolving speed falls within a third revolving speed range, the control unit outputs a third control demand to the rectify device to control the rectify device not to output voltage;
• and
• wherein the first revolving speed range is less than or equal to 3000 revolutions per minute;
• the second revolving speed range is greater than 3000 revolutions per minute and less than or equal to 3800 revolutions per minute;
• and the third revolving speed range is more than 3800 revolutions per minute.
