Abstract
Systems, apparatuses, and methods of controlling an ignitor are disclosed. A method includes: receiving, by a controller, fuel quality data regarding a fuel for a spark-ignition engine; determining, by the controller, a fuel quality metric based on the fuel quality data; and controlling, by the controller, an ignition energy characteristic of an ignitor in response to the fuel quality metric.
Claims20
A method, comprising:
- receiving, by a controller, fuel quality data regarding a fuel for a spark-ignition engine;
- determining, by the controller, a fuel quality metric based on the fuel quality data;
- and
- controlling, by the controller, an ignition energy characteristic of an ignitor in response to the fuel quality metric.
1 more element
An apparatus, comprising:
- an ignition control circuit comprising at least one memory storing machine readable instructions and at least one processor, the machine readable instructions structured to cause the at least one processor to perform operations comprising:
- receiving fuel quality data regarding a fuel for a spark-ignition engine;
- determining a fuel quality metric based on the fuel quality data;
- and
- controlling an ignition energy characteristic of an ignitor in response to the fuel quality metric.
2 more elements
A system, comprising:
- a fuel quality sensor structured to receive fuel quality data of a fuel for a spark-ignition engine;
- an ignition control unit coupled to the fuel quality sensor and structured to determine a fuel quality metric based on the fuel quality data;
- and
- an ignitor coupled to the ignition control unit, the ignition control unit structured to control the ignitor based on the fuel quality metric.
