Stepless variable fuel injection advance angle device of cetane number measuring machine

The utility model discloses a stepless variable fuel injection advance angle device of a cetane number measuring machine. The stepless variable fuel injection advance angle device comprises a controller, a heat-insulating moisture-proof plate, a mounting piece and a containing block. According to the utility model, through the cooperative use of the heat-insulating and moisture-proof plate, the mounting piece, the fixing mechanism and the transmission mechanism, the heat-insulating and moisture-proof plate can protect the controller, the fixing mechanism can fix the heat-insulating and moisture-proof plate and the mounting piece, and the transmission mechanism can move the fixing mechanism out of the interior of the mounting piece, so that the heat-insulating and moisture-proof plate is separated from the mounting piece; the stepless variable fuel injection advance angle device of the cetane number measuring machine solves the problems that an existing advance angle ignition controller is not provided with a
