Publication number: 20240096577Abstract: A temperature fuse assembly for a high-power DC circuit is provided. The temperature fuse assembly includes a case extending from a first case end to a second case end and an isolated lead projecting from the second case end. A bushing electrically isolates the isolated lead from the case. A high-gauge wire is electrically connected to the case at a first wire end and electrically connected to the isolated lead at a second wire end. A portion of the high-gauge wire is helically wound about an exterior of the bushing. When a temperature of the temperature fuse assembly exceeds a threshold temperature, the temperature fuse assembly is configured to conduct a DC current of the high-power DC circuit through the high-gauge wire. The high-gauge wire is configured to melt under a load of the DC current and interrupt the high-power DC circuit.Type: ApplicationFiled: September 15, 2023Publication date: March 21, 2024Applicant: Therm-O-Disc, IncorporatedInventors: Changcai ZHAO, Lijuan HUANG, Wei SHI, Kangsheng LIN, Guojun XIAO, Rong GUAN, Xiang GONG, Qiang ZHAO

Publication number: 20060225527Abstract: 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.Type: ApplicationFiled: April 6, 2005Publication date: October 12, 2006Inventors: Ching-Min Yang, Guojun Shi

Patent number: 6877486Abstract: 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.Type: GrantFiled: September 15, 2003Date of Patent: April 12, 2005Assignee: General Motors CorporationInventors: Benjamin D.

Patent number: 6802181Abstract: 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.Type: GrantFiled: January 14, 2003Date of Patent: October 12, 2004Assignee: General Motors CorporationInventors: Wenbo Wang, Matthew J.

Patent number: 6694243Abstract: 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.Type: GrantFiled: February 27, 2001Date of Patent: February 17, 2004Assignee: General Motors CorporationInventors: Guojun Shi, Sharanjit Singh, Minghui Kao, David N.

Patent number: 6631611Abstract: 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.Type: GrantFiled: May 30, 2001Date of Patent: October 14, 2003Assignee: General Motors CorporationInventors: Guojun Shi, Sharanjit Singh, Minghui Kao, David W.

Patent number: 6128948Abstract: 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.Type: GrantFiled: February 16, 1999Date of Patent: October 10, 2000Assignee: General Motors CorporationInventors: Guojun Shi, James R.
