摘要： Methods and apparatus for accurately predicting a fuel injector tip temperature (FITT) are described. One technique for predicting the temperature of a fuel injector tip in an engine suitably includes the steps of estimating an initial temperature of the fuel injector tip and calculating a steady state temperature of the fuel injector tip. A filter coefficient is determined as a function of a rate of airflow into the engine, and the temperature of the fuel injector tip is predicted as a function of said initial temperature, the steady state temperature, and the filter coefficient. In a further embodiment, the steady state temperature is filtered into a feedback temperature at a rate that is determined by the filter coefficient.

摘要： A method for monitoring engine coolant warm-up behavior utilizing a model-based algorithm which provides a moving threshold for accumulated air or accumulated fuel entering into the engine. The algorithm allows for coolant temperature monitoring under a wide range of transient and steady state driving conditions while maintaining safeguards that prevent a false detection. The accumulated air (or fuel) delivered to the engine during the warm-up interval is used to represent the total heat generated by the engine during the warm-up interval. A time-varying moving calculated accumulated air threshold is therefore defined which can deliver accurate pass-fail decisions in conjunction with a predetermined target temperature.

摘要： An automatic transmission utilizes a shift support system using combination of coupled clutch assemblies with a fluid drive and a gear system to provide multi-speed ratios with one reverse ratio without excessive heat generation. The fluid drive has an impeller and a turbine, and each coupled clutch assembly has two respective inputs from the fluid drive impeller and turbine with one output to the gear system. Each coupled clutch assembly provides possibilities of either connection or disconnection for engine to alternatively obtain different gear ratio speeds, or drive both odd and even gears at the same time for a smooth shift transition. Utilization of the shift support system with torque transmitting elements to provide connections between different gear sets allows the transmission to be operated in higher reliability and less complicated control than dual clutch transmission with similar efficiency.

摘要： Method and apparatus to monitor secondary air injection and catalyst conversion efficiency. The method includes operating an engine in a rich condition after detecting an engine steady state condition. The secondary air injector injects air into an exhaust stream to simulate a lean engine condition. The injection of the air into the exhaust stream is ceased after both inlet and outlet sensors detect the lean condition. After ceasing air injection, a lag time is determined between the inlet sensor detecting the rich condition and the outlet sensor detecting the rich operating condition. An oxygen storage capacity of the catalytic converter is calculated based on the lag time. An efficiency of the catalytic converter is determined as a function of the storage capacity. Additionally, performance of the secondary air injector is monitored. If the inlet sensor fails to detect the lean condition after the secondary air injector is active, a fault is signaled.

摘要： An on-board catalyst diagnostic for monitoring the conversion efficiencies of a catalytic converter by measuring the oxygen storage capacity (OSC) of the converter. The measurement of the OSC indicates the degree of health of the converter. Under the same engine running conditions, the greater the OSC measurement, the healthier the converter. A modeled OSC is compared to the real OSC to determine a normalized OSC. The normalized OSC is compared to a predetermined threshold value in order to determine the health of the converter. The modeled OSC takes into consideration variables which will affect the value of the OSC.

摘要： A method of initializing the catalyst converter for monitoring the conversion efficiencies of a catalytic converter by measuring the oxygen storage capacity (OSC) of the converter. The measurement of the OSC indicates the degree of health of the converter. Under the same engine running conditions, the greater the OSC measurement, the healthier the converter. The catalyst needs to be set to either a rich state or a lean state prior to the measurement of its OSC time. This process is called catalyst state initialization. The catalyst has to be fully saturated from test to test in order to make consistent OSC measurements. This is through open loop fuel control by commanding a lean air to fuel ratio and then monitoring thepost-O2 sensor voltage until it falls below a calibrated value (e.g. 80 mV) indicating a lean state. The system continues to command a lean air to fuel ratio (e.g. 6%) for a calibrated duration of time (e.g. 3 seconds) to saturate the catalytic converter and drive it to a fixed saturation state. This ensures consistent OSC measurement in the second stage of the test.
