Rotational generation type wireless oxygen sensor
First Claim
1. An apparatus utilizing an oxygen sensor in an exhaust system of a motor vehicle, the apparatus comprising:
- an outer shell;
an electrode disposed in the outer shell, the electrode measuring an amount of oxygen in an exhaust gas passing through a tail pipe of the motor vehicle and generating a signal based on the measured amount of oxygen;
a first wireless communication device disposed within the outer shell wirelessly transmitting the signal from the electrode;
an integrated circuit chip controlling functions of the oxygen sensor; and
a power-storing device within the outer shell providing power to at least the first wireless communication device and the integrated circuit chip.

Abstract
An oxygen sensor for a motor vehicle having an electrode within an outer shell measures oxygen in exhaust gas exiting the vehicle and generates a signal based on the oxygen measurement. A communication device, powered by a battery or capacitor, wirelessly transmits the measured amount of oxygen from the electrode to a powertrain control module. The flow of exhaust gas through the exhaust system spins blades to spin a generator in a rotational power generation device to generate electrical current to be stored and used by the battery or capacitor. The rotational power generation device may be located in the exhaust pipe, such as through an exhaust pipe wall, and either be connected to the oxygen sensor shell or separate and connected only with electrical wires between the generator and the battery or capacitor.
