Engine roughness is compared with the critical value(S3), and the valve overlap is decreased in case of engine roughness to be over the critical value(S4). The valve overlap is compared with the maximum value(S5), and the valve overlap is increased in case of the valve overlap to be less than the maximum valve overlap(S6).

Abstract: PURPOSE: A starting control method of an engine is provided to improve the cold starting efficiency by maximizing a suction valve timing. CONSTITUTION: A starting of an engine is detected by an on/off switching of a starting key. An ECU(Electronic Control Unit) checks the temperature of coolant by feeding from a coolant temperature sensor. In having the lower temperature than a critical temperature, the ECU calculates RPM(Revolution Per Minute) by feeding signals from a crank position sensor, a throttle position sensor and so on. In exceeding the RPM over a first critical RPM, the ECU maintains a maximum advance of an oil flow control valve until the RPM is reached to a second critical RPM. In having the higher temperature than the critical temperature or exceeding the RPM over the second critical RPM, the ECU maximize the oil flow control valve by setting the advancing time of the oil flow control valve as 0%.
