    Abstract: An embodiment system for controlling an ignition coil includes a first ignition coil including a first primary coil and a first secondary coil, a second ignition coil including a second primary coil and a second secondary coil, a spark plug including a pair of electrodes configured to generate a spark discharge by a discharge current generated by the first ignition coil and the second ignition coil, and a controller configured to selectively perform a multi-stage ignition through the first ignition coil and the second ignition coil or a single-stage ignition through the first ignition coil or the second ignition coil depending on an operation region of an engine and, in response to a misfire occurring in the engine while performing the multi-stage ignition, to adjust a number of ignitions or a dwell time.

    Abstract: An ignition coil control method may include receiving first pulse signal and second pulse signal following the first pulse signal by a delay time transmitted from an engine control unit; charging the first ignition coil when the first pulse signal is on; charging the second ignition coil when a predetermined time period elapses from a time at which the first pulse signal is on; discharging the first ignition coil when the first pulse signal is off; discharging the second ignition coil when a maintaining time of the first pulse signal from a time at which the second ignition coil is charged; when the second pulse signal is on, charging the first ignition coil for a dwell time and then discharging the first ignition coil; and charging the second ignition coil for the dwell time and then discharging the second ignition coil when a predetermined time period elapses from a time at which the second ignition coil is discharged.

    Abstract: A variable compression ratio apparatus includes: a piston defining a combustion chamber, a connecting rod connected to the piston; an eccentric link eccentrically connected to the piston, a swing link connected to the eccentric link so as to rotate the eccentric link, a crankpin to which the connecting rod is connected, and a crank web disposed at both sides of the crankpin and provided with a guide portion for guiding downward motions of the eccentric link and the swing link when the eccentric link and the swing link move downward. Thereby, the downward motions of the eccentric link and the swing link are stabilized.
