Abstract:
Methods and systems are provided for relieving pressure from a compression locked engine. The engine may be compression locked during an engine start attempt due to operator application of a manual transmission clutch at or around the time of a first combustion event of the engine start. A direct injector of the compression locked cylinder is commanded open to relieve the pressure into the fuel rail.

Claim (Index 16):
A vehicle system, comprising:\n an engine; a fuel system including a high pressure fuel pump, a fuel rail, and a plurality of direct fuel injectors coupled to the fuel rail, each of the plurality of direct fuel injectors coupled to a corresponding engine cylinder; a manual transmission including a clutch actuated by an operator foot pedal; a starter motor driven by a battery; a crankshaft position sensor coupled to a crankshaft of the engine; and a controller with computer readable instructions stored on non-transitory memory for:\n during an engine start,\n cranking the engine via the starter motor until a threshold speed is reached; \n then resuming spark and fuel delivery into a first cylinder selected based on piston position; \n actuating the clutch based on operator input; \n indicating compression locking of the engine during the engine start based on an output of the sensor; and \n responsive to the indication of compression locking, commanding one of the plurality of direct injectors coupled to the first cylinder open for a duration before attempting a subsequent engine start.
