Patent number: 10145716Abstract: A mass airflow sensor according to the present disclosure includes a housing, a sensor element, and a flow deflector. The housing defines an airflow passage configured to receive air flowing in a first direction. The sensor element is disposed in the airflow passage and generates a signal indicating a mass flow rate of air flowing through the airflow passage. The flow deflector is disposed in the airflow passage downstream of the sensor element, extends from an inner wall surface of the airflow passage, and is configured to inhibit air flow through the airflow passage in a second direction that is opposite of the first direction.Type: GrantFiled: March 16, 2016Date of Patent: December 4, 2018Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Guangzhi A. Zhao, Bryant G. Hammond, Christopher K. Clarke

Patent number: 10100704Abstract: An exhaust manifold for a vehicle engine may include a plurality of pipes, a pod, a splined collector and a downpipe. Each pipe in the plurality of pipes are operatively configured to be coupled to a corresponding engine chamber at a proximate portion. The pod is operatively configured to align a flow of exhaust gas emerging from each of the corresponding engine chambers to the associated pipe in the plurality of pipes. The splined collector receives the outlet ends of the pipes at a splined collector inlet. The downpipe may be affixed to the splined collector at a small diameter outlet portion. The downpipe includes a first oxygen sensor operatively configured to communicate with a second oxygen sensor disposed in a downstream catalytic converter and an ECM in order to regulate air and fuel for the vehicle engine.Type: GrantFiled: November 10, 2016Date of Patent: October 16, 2018Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Guangzhi A. Zhao, Kenneth L. Marotta, Vincent J. Tylutki, Charles F. Maguire, III

Publication number: 20180274468Abstract: An exhaust system for a vehicle includes a catalytic converter, an exhaust manifold, an outlet sensor in addition to inlet and outlet pipes. The catalytic converter includes an integrated oxygen sensor mount, an entry, and an outlet. The integrated oxygen sensor mount operatively configured to receive an outlet sensor. The exhaust manifold may be operatively configured to couple a vehicle combustion chamber to the entry of the catalytic converter via a front pipe. The inlet sensor may be affixed to the front pipe upstream of the catalytic converter wherein the inlet sensor and the outlet sensor are in communication with an engine control module. The outlet pipe may be affixed to the outlet of the catalytic converter.Type: ApplicationFiled: March 24, 2017Publication date: September 27, 2018Inventors: Guangzhi A. Zhao, Vincent J. Tylutki, Leo P. Craglow

Patent number: 10018164Abstract: A gas compressor assembly configured to pressurize an airflow received from the ambient for delivery to an internal combustion engine having a cylinder includes a compressor housing. A compressor wheel is disposed inside the compressor housing and configured to pressurize the airflow. A compressor bypass is configured to direct the pressurized airflow away from the cylinder. A pressure relief valve is configured to selectively open and close the compressor bypass to thereby limit pressure of the pressurized airflow and minimize surge of the compressor wheel. A baffle arranged inside the compressor bypass is configured to dissipate energy of a sound wave generated by the pressurized airflow upon an initial opening of the pressure relief valve. An internal combustion engine employing such a turbocharger is also disclosed.Type: GrantFiled: February 2, 2016Date of Patent: July 10, 2018Assignee: GM Global Technology Operations LLCInventors: Guangzhi A. Zhao, Christopher K. Clarke
