Abstract
Some embodiments of the present disclosure include a system for allowing spark ignition fuel injected engines to function on a plurality of fuels. The system may include an engine system including an engine control module operatively attached to a fuel injector, and a fuel tank attached to the fuel injector, a fuel content sensor configured to sense a content of a fuel in the engine system before combustion of the fuel, and a fuel control module placed inline with the fuel injector and the fuel content sensor, the fuel control module configured to receive fuel content information from the fuel content sensor and make a change to the fuel injector pulse width based on the fuel content information, if necessary.
Claims14
A system for engagement with a spark ignition fuel injection system, the spark ignition fuel injection system including an engine system comprising an engine control module operatively attached to a fuel injector, and a fuel tank attached to the fuel injector, the system comprising:
- a fuel content sensor positioned externally of the fuel tank and configured to sense a content of fuel in the engine system before combustion of the fuel;
- and
- a fuel control module, the fuel control module bi-directionally communicatively coupled with the engine control module, communicatively coupled to the fuel injector, and configured to receive fuel content information from the fuel content sensor and control both the information sent to the engine control module and the fuel injection pulse width instructions sent to the fuel injector, based on algorithmic assessment by the fuel control module of the fuel content information as detected, the fuel control module comprising:
- a central processing unit coupled with a memory device;
- and
- the memory device containing software-encoded commands, algorithms, and values selectively operable to direct the fuel control module to:
- receive a first measurement signal from the fuel content sensor;
- select a first pre-established algorithm to apply;
- derive with the selected first algorithm applied to the first measurement signal a second signal for input into the engine control module in an operation of the engine control module;
- provide the derived second signal to the engine control module;
- receive a first fuel pulse width command from the engine control module directed to the fuel injector;
- select a second pre-established algorithm to apply;
- derive with the second algorithm an appropriate second fuel pulse width command for an operation of the fuel injector based on the first fuel pulse width command received from the engine control module;
- and
- provide the derived second fuel pulse width command to the fuel injector.
