Abstract
Systems and methods for increasing an efficiency of engine starting of a hybrid vehicle are disclosed. In one example approach, a method comprises operating a laser ignition device in an engine cylinder and identifying engine position in response thereto; and igniting an air and fuel mixture in the cylinder with the laser ignition device.
Claims20
A method, comprising:
- operating a laser ignition device in an engine cylinder;
- synchronizing fuel delivery based on laser sensed engine position;
- and
- igniting an air and fuel mixture in the cylinder with the laser ignition device.
1 more element
A method, comprising:
- synchronizing a first combustion event from rest of an engine start by operating a laser ignition device coupled to an engine cylinder to identify engine position in response to sensed light in the cylinder;
- and
- igniting an air and fuel mixture in the cylinder with the laser ignition device, with a timing of the igniting based on the identified engine position.
A method, comprising:
- shutting down an engine in response to idle-stop conditions;
- synchronizing a first combustion event from shutdown of an engine restart, operating a laser ignition device in an engine cylinder and identifying engine position in response to sensed light in the cylinder;
- and
- igniting an air and fuel mixture in the cylinder with the laser ignition device, with a timing of the igniting based on the identified engine position.
