Abstract

An engine comprises a timer (20), which is provided with a temperature-sensing operation mechanism (7). During a cold-starting term, a downstream interlocking portion (2) advances by an advancing operation of the timer (20) based on an operation that the temperature-sensing operation mechanism (7) makes upon sensing the temperature. While the engine is warm, the downstream interlocking portion (2) cancels an advancement by an advancement-cancellation operation of the timer (20) based on another operation that the temperature-sensing operation mechanism (7) makes upon sensing the temperature. The engine oil (56) within the engine is supplied from the oil-supply port (58) to the timer (20), thereby enabling the engine oil (56) in liquid state to contact the temperature-sensing operation mechanism (7).
