Abstract: The present invention relates to a method for controlling an electronic continuous variable valve timing device to improve the starting performance of an engine by the simple phase control of a cam shaft. According to an embodiment of the present invention, the method for controlling an electronic continuous variable valve timing device is to change the intake air and exhaust timing of the engine depending on the phase of the cam shaft The present invention comprises the steps of: determining whether or not turning off the engine is requested during driving; recognizing the phase of the cam shaft so as to advance the intake air timing of the engine depending on a target phase; and finishing the phase control of the cam shaft depending on the status of the engine or the cam shaft. [Reference numerals] (S110) Detect Driving environments;(S120) Control set timing;(S130) Is an engine turned off?;(S140) Recognize a target starting phase (T_n);(S150) Engine RPM > Minimum RPM (R)?;(S160) Control the advance of a cam shaft;(S170) Phase of the cam shaft >= Minimum advance?;(S180) Phase of the cam shaft = Maximum advance?

Abstract: According to an embodiment of the present invention, an engine with a variable valve timing device and a variable tumble device may comprise: a variable valve timing device advancing or retarding the rotation of an intake cam shaft or an exhaust cam shaft; an intake valve or an exhaust valve opening or closing an intake port or an exhaust port by being operated by the cam of the intake cam shaft or the exhaust cam shaft; and the variable tumble device arranged in the intake port and at the upper stream of the intake valve, forming a tumble in a combustion chamber by varying the flow path of a gas sucked into the intake port. Therefore, the desired operation timing of a valve can be variably applied by the variable valve timing device and the combustion efficiency can be improved by simultaneously forming the tumble.

Abstract: Disclosed are a variable intake manifold for an internal combustion engine and a variable air intake device using the same. The variable intake manifold includes an intake port through which external air flows; first and second outlet ports through which the external air fed via the inlet port is discharged via different passages; a partition dividing a part of a first intake passage extending from the inlet port to the first outlet port and a second intake passage extending from the inlet port to the second outlet port into an upstream passage and a downstream passage. The lengths of the partitions positioned in the first and second intake passages are set to be different, and a port flap valve device for opening or closing the downstream passage is provided to form tumble flow and swirl flow which are strong against the intake air fed to the combustion chamber.
