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.

An electronic interface circuit assembly for use with an internal combustion engine and positioned between an oxygen sensor and an electronic control unit of an automobile, comprising:
- a first connector coupled to receive an input signal from the oxygen sensor;
- a second connector coupled to send an output signal to the electronic control unit;
- a first diode connected to the first connector to direct the input signal to the second connector;
- an interface circuit, comprising:
- an input port coupled to receive the input signal from the first connector;
- a switch coupled with the input port and 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;
- an output port coupled with the switch and providing the output voltage to the second connector;
- and
- a second diode connected to the input port to direct the output voltage to the output port to produce the output signal that is indicative of the input signal and the output voltage.
