Methods and apparatus for limiting engine speed

An engine system for limiting engine speed, comprising:

• multiple engine components usable to limit engine speed, the multiple components including at least one of a fuel injection system, an ignition system, and a throttle;
• a user interface manually actuable to select at least one of the multiple engine components for limiting engine speed, the user interface including an identification signal generator and transmitter that is configured to, upon selection of the at least one of the multiple engine components, generate and transmit an identification signal that identifies the at least one of the engine components that was selected;
• and
• a controller that is configured to, upon receipt of the identification signal, provide an instruction to the identified at least one of the engine components, such that the identified at least one of the engine components operates to limit engine speed upon occurrence of conditions warranting that engine speed be limited.

A method for limiting engine speed using multiple engine components, including at least one of a fuel injection system, an ignition system, and a throttle, the method comprising:

• providing a user with an ability to select at least one of the multiple engine components for limiting engine speed;
• generating and transmitting, upon selection of the at least one of the multiple engine components, an identification signal that identifies the at least one of the engine components that has been selected;
• and
• providing, upon receipt of the identification signal, an instruction to the identified at least one of the engine components, such that the identified at least one of the engine components operates to limit engine speed upon occurrence of conditions warranting that engine speed be limited.
