Latest Patents

One of his latest patents is an automated method for cold transient fuel compensation calibration. This innovative method generates compensation values for use in an electronic engine controller during transient engine operation. The process begins by exposing an engine to an ambient temperature value to set an initial start temperature. The engine is then started and operated until it reaches a stable operating temperature. The mass flow rate of air into the engine's induction system is detected, along with the temperature of the engine coolant and the composition of exhaust gas. These detected values are stored, and the engine is exposed to various ambient temperatures to generate data indicative of its operation. The compensation values are calculated based on model values derived from the stored data.

Another significant patent involves the detection of catalytic converter operability by light-off time. In this invention, an electronic engine controller monitors the operability of a catalytic converter upon engine ignition. It senses the temperature of the exhaust gas entering and exiting the converter, calculating the rate of heat transfer and the temperature of the catalyst material. This data is used to determine the light-off time, which is checked against a predetermined trend to identify any inoperative conditions of the converter.
