Abstract
An interface circuit assembly for use with an electronic control unit and oxygen sensor of an internal combustion engine. The assembly includes an input port coupled to receive a signal from the oxygen sensor and a processing unit coupled with the input port. The processing unit increases the signal to an output voltage as a function of hydrogen being provided to the internal combustion engine. An output port is coupled with the processing unit and provides the output voltage to the electronic control unit.
Claims16
A method of operating an interface circuit assembly of an internal combustion engine, comprising:
- receiving an input signal from an oxygen sensor using a first connector;
- using a first diode to direct the input signal to a second connector;
- transforming the input signal to an output voltage by adding voltage to the input signal as a function of hydrogen and gasoline being provided to the internal combustion engine;
- providing a second connector configured to send an output signal to an electronic control unit;
- and
- directing the output voltage using a second diode to produce the output signal to the electronic control unit that is indicative of the input signal and the output voltage.
