Abstract:
Methods and systems are provided for reducing accumulation of condensate in an engine intake during an engine non-combusting condition. In one example, during an engine non-combusting condition, responsive to a higher than threshold ambient humidity and a lower than threshold intake manifold temperature, intake and exhaust valves of deactivatable cylinders may be closed in order to seal the cylinders and during an immediately subsequent engine combusting condition, the intake and exhaust valves of the deactivatable cylinders may be activated and combustion may be resumed in the deactivatable cylinders before starting combustion in non-deactivatable cylinders. Also, during the engine non-combusting condition, residual hot exhaust may be recirculated to the intake manifold to evaporate condensate in the intake manifold.
