摘要： A system is described using a fuel quality sensor for controlling various aspects of engine operation. In particular, an acoustic wave sensor is utilized to measure viscosity and density of gasoline fuels. This measurement is utilized to predict engine combustion quality during an engine start. Based on the prediction, the method adjusts engine operating parameters (such as fuel injection amount and ignition timing) to achieve improved vehicle driveability and engine combustion.

摘要： An electrospray adapted fuel injection valve includes an anode and cathode to inject monopolar electric charge into electrically insulating fuel. On exiting the injector, the charge containing fuel atomizes and disperses to reduce electrostatic energy. Additional electrodes with an appropriate method of biasing extend the range of applicability of the process by adjusting space charge distribution within the injector to compensate for variability in component manufacture and variability in the electrical conductivity of the fuel.

摘要： A method of operating a gas sensor is disclosed, wherein the sensor includes a pumping electrode configuration and a measuring electrode configuration, and wherein the method includes operating the sensor in a first mode in which a first, lower pumping potential sufficient to electrochemically remove an interfering compound from the sensor without electrochemically removing the analyte from the sensor is applied across the pumping electrode configuration and a measuring potential sufficient to electrochemically remove the analyte from the sensor is applied across the measuring electrode configuration; and operating the sensor in a second mode in which a second, higher pumping potential sufficient to electrochemically remove the analyte from the sensor is applied to the pumping electrode configuration.

摘要： A fuel injection system used in the intake air passageway of an internal combustion engine has a strategy for reducing cold start hydrocarbon emissions. The fuel injector has an actuator which allows the fuel spray pattern to be varied from one which is widely dispersed and atomized to one which is only weakly dispersed. A strategy for varying the spray pattern during the engine warm-up period after cold start is disclosed. The strategy increases evaporation within the passageway so that cold start overfuelling and attendant hydrocarbon emissions are reduced.

摘要： An automotive fuel injector having a fluorine-coating amphorous hydronated carbon film coating to resist the formation of carbonaceous deposits thereon. The fluorine-coating amphorous hydronated carbon film is made in part form trifluoromethyltrimethylsilane. The coating helps the fuel injector resist coking or the growth of hard carbonaceous deposits. This reduction in coking and deposits improves the fuel economy and engine performance.
