Abstract: This invention is an on-board means to verify that a vehicle's exhaust emissions control system functions normally. It monitors hydrocarbon (HC) exhaust emissions for a few minutes after a cold start or at other selected times. If used from cold start, it is an on-board approximation to taking the first bag sample in an FTP test. The measurement involves storing a portion of the exhaust HC. Various embodiments are discussed. Some involve measuring the cumulative amount of stored HC (as on a substrate) during the test. Other embodiments wait until the end of the test to measure the amount of stored HC. At the end of each test (or trip), the storage means is returned to an empty state to await the next test. If HC is stored on or in a substrate, for example, the temperature of the substrate is raised. This decreases the amount of stored HC vapor and renews the substrate for the next test.

Abstract: A sensor and method for measuring the volatility of liquid gasoline by estimating its driveability index includes a sensing element having an interdigitated array of electrically conducting capacitor plates arranged to retain a predetermined volume of gasoline, the volatility of which is to be measured. The sensing element is mounted in a vehicle to be in contact with the flow of gasoline while the engine is running so that a volume certain of gasoline is drawn between and remains within the electrically conducting plates when the engine is turned off. The sensing element is connected to circuitry used to measure the change in capacitance of the sensing element as a function of time while simultaneously measuring the temperature change of the sensing element as the volume of gasoline retained by the sensing element is evaporated over time. The measurements obtained by the circuitry are used in estimating the drivability index of the gasoline.

Abstract: The invention includes an on-board diagnostic system for monitoring exhaust gas from an automotive combustion engine and includes a sample port connected to the exhaust piping, preferably downstream from the catalytic converter. The exhaust port leads to a sample cell to which an infrared spectrometry system is operably connected to measure the concentration of hydrocarbons in the sample cell. An air pump is connected to the exhaust port and communicates with the sample cell. The air pump is operated to continuously purge the sample cell by pushing small amounts of clean air through the sample cell into the exhaust.

Abstract: A method for analyzing automotive vehicle emissions detects and logs significant engine events over a test period, and applies the logged events to a model defining the emissions impact of such events to yield a vehicle emissions estimate for the test period. The method includes a diagnostic for diagnosing a deviation in performance of emissions control systems away from an expected performance and for correcting the vehicle emissions estimated to reflect the operating condition of the emissions control systems.
