PROBLEM TO BE SOLVED: To provide an engine capable of swiftly conducting advancement cancellation after cold start. SOLUTION: The engine comprises an upstream interlocking portion 1 near a crank shaft, which is interlockingly connected through a timer 20 to a downstream interlocking portion 2. The timer 20 is provided with a temperature-sensing operation means 7. During a cold-starting term while the temperature-sensing operation means 7 senses a temperature of a value less than a predetermined one, the downstream interlocking portion 2 advances by an advancing operation of the timer 20 based on an operation that the temperature-sensing operation mean 7 makes upon sensing the temperature. While the engine is warm, the temperature-sensing operation means 7 senses a temperature of a value not less than the predetermined one, 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 mean 7 makes upon sensing the temperature. In this engine, engine oil 56 force-feeded by an oil pump 57 is circulated in the engine and the oil pump 57 is communicated with an oil injection port 58 and the engine oil 56 injected from the oil injection port 58 is supplied to the timer 20, thereby enabling the engine oil 56 to contact the temperature-sensing operation means 7.
