Patent ID: 7481193

Claim:
An engine comprising an upstream interlocking portion ( 1 ) near a crank shaft ( 49 ), which is interlockingly connected through a timer ( 20 ) to a downstream interlocking portion ( 2 ), the timer ( 20 ) being provided with a temperature-sensing operation means ( 7 ), during a cold-starting while the temperature-sensing operation means ( 7 ) senses a temperature of a value less than a predetermined one, the downstream interlocking portion ( 2 ) being made to advance by an advancing operation of the timer ( 20 ) based on an operation that the temperature-sensing operation means ( 7 ) makes upon sensing the temperature, during a warm term of the engine while the temperature-sensing operation means ( 7 ) senses a temperature of a value not less than the predetermined one, the downstream interlocking portion ( 2 ) canceling its advancement by an advancement-cancellation operation of the timer ( 20 ) based on another operation that the temperature-sensing operation means ( 7 ) makes upon sensing the temperature, wherein an oil pump ( 57 ) for an engine oil ( 56 ) is communicated with an oil-supply port ( 58 ) and the engine oil ( 56 ) within the engine, which has passed an oil gallery within a cylinder block ( 58 b ), is supplied from the oil-supply port ( 58 ) to the timer ( 20 ), thereby enabling the engine oil ( 56 ) in liquid state to be brought into contact with the temperature-sensing operation means ( 7 ), the engine oil ( 56 ) transmitting the increase of the engine's temperature to the temperature-sensing operation means ( 7 ) to cancel the advancement after the cold-starting.
