Abstract:
Methods and systems are provided for drying engine cylinders in situ responsive to engine flooding. In one example, a laser ignition device is operated in each engine cylinder, sequentially, while the cylinder is parked with an intake valve closed and an exhaust valve open. The heat generated by the laser operation vaporizes liquid fuel in the cylinder, which flows out of the cylinder via the open exhaust valve, expediting cylinder drying.

Claim (Index 16):
A vehicle system, comprising:\n an engine including a plurality of cylinders, each of the plurality of cylinders including a corresponding laser ignition device and a fuel injector; an intake passage including an intake throttle, the throttle coupled to a throttle position sensor; an exhaust passage including an exhaust gas air-fuel ratio sensor; an electric motor; and a controller with computer readable instructions stored on non-transitory memory for:\n responsive to an unsuccessful engine start attempt, indicating engine flooding based on intake throttle position and air-fuel ratio sensor output during the unsuccessful engine start attempt; and \n responsive to the indication of engine flooding, disabling engine fueling, and sequentially drying each of the plurality of cylinders via operation of the corresponding laser ignition device while holding a corresponding cylinder at an exhaust stroke TDC position.
