Abstract
An ignition coil includes an ignition circuit having a first winding and a second winding, a controller in communication with the ignition circuit, and a light. The ignition circuit is configured to output an ignition timing signal. The controller is configured to establish a rule that limits an engine speed to a maximum engine speed to be provided by the ignition timing signal. The light is configured to illuminate and indicate the maximum engine speed in response to an output signal from the controller.
Claims20
An ignition coil for an internal combustion engine, comprising:
- an ignition circuit including a first winding and a second winding, the ignition circuit being configured to output an ignition timing signal;
- a controller in communication with the ignition circuit, the controller configured to establish a rule that limits an engine speed to a maximum engine speed to be provided by the ignition timing signal;
- and
- a light configured to illuminate and indicate the maximum engine speed in response to an output signal from the controller.
An engine, comprising:
- an engine block having a cylinder defining a cylinder axis;
- a crankshaft defining a crankshaft axis;
- a piston configured to reciprocate along the cylinder axis and drive the crankshaft about the crankshaft axis;
- a flywheel coupled to the crankshaft and comprising a magnet;
- an ignition system configured to generate a spark, the ignition system including:
- an ignition circuit having a first winding and a second winding, the ignition circuit being configured to output an ignition timing signal, the first winding being positioned proximate the flywheel;
- an indicator;
- and
- a controller in communication with the first winding and configured to:
- establish a rule that limits an engine speed to a maximum engine speed to be provided by the ignition timing signal;
- and
- present, via the indicator, information regarding the maximum engine speed to be provided by the ignition timing signal.
A method for operating an engine, comprising:
- establishing, via a processing circuit of an ignition coil, a rule for limiting an engine speed to a setpoint value;
- presenting, via a user interface of the ignition coil, information regarding the setpoint value;
- and
- operating, via the processing circuit of the ignition coil, an ignition circuit based on the setpoint value, wherein the ignition circuit is configured to generate an ignition signal.
