Abstract: PROBLEM TO BE SOLVED: To improve a fuel consumption effectively without the deteriolation of an emission and engine vibration, in a variable cylinder control system. SOLUTION: In the pause cylinder in a cylinder reduced operation, an intake valve 13 is maintained to a valve closing state in an entire stroke (intake, compression, explosion and exhaust stroke) and an exhaust valve 15 is opened in the exhaust stroke and intake stroke and closed in a compression stroke and explosion stroke. Thereby, in the pause cylinder in a cylinder reduced operation, the exhaust gas with a high pressure is sucked from an exhaust port 14 into the cylinder and exhausted from an exhaust port 14 after being compressed and expanded. At the shifting time from the all cylinder operation to the cylinder reduced operation, the intake/exhaust valve control of the cylinder reduced operation is started from the intake stroke after one combustion cycle is elapsed from the final fuel injection to the cylinder which is the pause cylinder.  At the shifting time from the cylinder reduced operation to all cylinder operation, the intake/exhaust valve control of all cylinder operation is started from the intake stroke just after the start of the fuel injection to the cylinder which is the pause cylinder.
