Sensor technology

Oxygen sensors have been placed in all cars and trucks produced for use in the United States since 1980. Current sensors are designed to measure the amount of oxygen in the exhaust gas and send the information to the car’s on-board computer. This information can then be used to indirectly determine the ratio of other gases being used by the engine and adjust several variables to improve performance, including air/fuel ratio and timing, in order to try and bring the engine into the optimum operating range. Both gasoline and diesel engines run best when the air-fuel mixture is correct, preventing:

• Failed Emission Tests
• Increased Fuel Consumption
• Failed Catalytic Converters
• Poor Drivability
• Increased Emissions
  

The lifetime of a typical sensor is about 30,000 to 50,000 miles. Heated sensors last around twice as long.
Failure is usually caused by the buildup of soot on the ceramic element.

The Company has secured worldwide exclusive rights to the sensor technology developed by Dr. Eric Wachsman while he was at the University of Florida (UFL). The sensor can replace the current sensor being used in gasoline and diesel engines in the market. The EPS sensor costs significantly less to manufacture, has a significantly more rapid response time, and can directly detect and reduce harmful emission such as NOx and CO. It has the ability to reduce all oxygenated gases. Most gasoline and diesel engines in the market today use at least four sensors, sometimes more, depending on size of the engine. More than $5 million has been spent on R&D at the UFL. EPS paid the University of Florida $2.1 million for the exclusive worldwide license and has a commitment to pay a 5% royalty to UFL based on net sales.

Potentiometric Sensor Technologies

As opposed to monitoring only oxygen, EPS’s Potentiometric sensors measure exact kinds and amounts of gases released into the atmosphere, which can be monitored and controlled in order to reduce the amount of greenhouse gases being released.  Potentiometric sensors do not use expensive ceramics, so they cost considerably less to manufacture than traditional oxygen sensors. The new sensors are designed to fit directly into a car’s engine control unit (ECU).
