Patent number: 10323601Abstract: A cooling jacket for an engine has upper and lower bodies. The upper body includes a plurality of upper portions. Each upper portion has a top orifice and a bottom orifice. The lower body is located below the upper body and includes a plurality of lower portions. Each lower portion has a lower orifice aligned with a respective one of the bottom orifices so as to permit a coolant to flow through the lower orifice and into the bottom orifice. The coolant flows from that lower portion to the respective one of the upper portions. Each upper portion has at least one upper passageway extending through that upper portion from the bottom orifice to the top orifice so that the coolant entering the upper passageway of that upper portion flows through the upper portion to the top orifice.Type: GrantFiled: October 10, 2017Date of Patent: June 18, 2019Assignee: GM Global Technology Operations LLCInventors: Akram R. Zahdeh, Dan L. Alden, Alan W. Hayman

Patent number: 8960134Abstract: A cooling system for an engine having a plurality of piston cylinders. The cooling system can include a liquid coolant source having liquid coolant and a cylinder cooling passage network having an inlet and an outlet for receiving and transmitting the liquid coolant. The cylinder cooling passage network having a plurality of individual upstream fluidic passages each being fluidly coupled to the inlet to directly receive the liquid coolant from the liquid coolant source in parallel flow. The cylinder cooling passage network further having a plurality of cylinder jacket passages each extending about at least a portion of a corresponding one of the plurality of piston cylinders and being positioned immediately adjacent thereto. The cylinder jacket passages are fluidly coupled directly to a corresponding one of the plurality of individual upstream fluidic passages to receive the liquid coolant and transmit the liquid coolant to the outlet for improved cooling performance.Type: GrantFiled: July 31, 2013Date of Patent: February 24, 2015Assignee: GM Global Technology Operations LLCInventors: Akram R. Zahdeh, Dan L. Alden, Colin Blacklock Bosman, Robert S. McAlpine

Patent number: 8739756Abstract: A cooling system for an engine assembly includes an engine block that defines a coolant flow passage configured to carry coolant through the engine block. The engine block also defines an oil flow passage configured to carry lubricating oil through the engine block. The oil flow passage at least partially surrounds the coolant flow passage and is sufficiently adjacent to the coolant flow passage so that the lubricating oil flowing in the oil flow passage is cooled by the coolant flowing in the coolant flow passage by heat transfer through the engine block. The engine block may define ridges along the coolant flow passage that increase a surface area of the coolant flow passage to increase heat transfer capability. The engine block may define two such coolant flow passages, a first and a second coolant flow passage, positioned so that the oil flow passage passes between the coolant flow passages.Type: GrantFiled: March 23, 2011Date of Patent: June 3, 2014Assignee: GM Global Technology Operations LLCInventors: Naser I. Hineiti, Dan L. Alden, Akram R. Zahdeh, Brian D. Kaminski

Patent number: 8550039Abstract: A method of manufacturing a pump assembly includes sand casting a pump housing with a cavity and die casting an impeller that includes pump blades and a first portion of a shroud. The pump housing may be sand cast as a one-piece component and the impeller may be die cast as another one-piece component. A pump cover is provided with a second portion of the shroud. The pump cover is inserted into the cavity so that the second portion of the shroud is adjacent to the first portion of the shroud, providing a substantially continuous surface defining flow channels through the impeller. A pump assembly manufactured according to the method is also provided.Type: GrantFiled: October 28, 2010Date of Patent: October 8, 2013Assignee: GM Global Technology Operations LLCInventors: Naser I.
