Patent ID: 8746185

Claim:
A control device for an engine equipped with a pump that circulates coolant, and having a flow rate of the coolant restricted, when a temperature of said coolant is lower than a threshold value, as compared to a case where the temperature of said coolant is equal to or higher than said threshold value, the control device comprising: a coolant temperature sensor that detects a temperature of said coolant; and a control unit that drives said pump so as to increase the flow rate of said coolant when the temperature detected by said coolant temperature sensor rises to a predetermined temperature lower than said threshold value, and stops said engine when a condition is satisfied including at least a condition that the temperature detected by said coolant temperature sensor after said pump is driven so as to increase the flow rate of said coolant is higher than a lower limit value lower than said predetermined temperature, in a case where the flow rate of said coolant is restricted.
