Figures 1 to 6 show the first embodiment. Figure 1 shows the wire attached to the fuel injection pump, Figure 2 shows the wiring from the injection pump to the exhaust pipe, and Figure 3 shows the cold start. Fig. 4 shows how the wire is attached to the thermowax side during normal operation, Fig. 5 shows how the exhaust pressure regulating valve is closed by the wire during low temperature startup,
FIG. 6 shows the open state of the exhaust pressure regulating valve by wire during normal operation. Figures 7 to 9 show the second embodiment; Figure 7 shows a state in which the motor switch is disposed on the thermowax side, Figure 8 shows a state in which the exhaust pressure regulating valve by the motor is closed, and Figure 9 shows a state in which the exhaust pressure regulating valve is closed by the motor. This shows the open state of the exhaust pressure regulating valve driven by the motor. 1st
