Patent number: 7950228Abstract: A turbo charge system of an engine minimizes energy loss of exhaust gas as a consequence of a crossover pipe that connects exhaust manifolds respectively mounted to cylinder heads at both sides of the engine with each other and that is mounted in each cylinder head, and the crossover pipe is formed as a double pipe structure. The turbo charge system of the engine may include a pair of exhaust manifolds respectively mounted to cylinder heads at both sides of the engine; a pair of turbo chargers connected respectively to the pair of exhaust manifolds and increasing intake air amount by using energy of exhaust gas; and a crossover pipe connecting the pair of exhaust manifolds with each other, wherein a crossover pipe is mounted in each cylinder head.Type: GrantFiled: November 21, 2007Date of Patent: May 31, 2011Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Sung Il Yoon, Hyoung-Hyoun Kim

Patent number: 7946112Abstract: An exhaust heat recovery device includes an accommodating portion extending continuously without shrinking a section therein and adapted to allow exhaust gas of an internal combustion engine to pass therethrough, a catalyst disposed in the accommodating portion for cleaning the exhaust gas, an evaporator disposed adjacent to the catalyst on a downstream side of an exhaust gas flow in the accommodating portion, and a condenser for condensing the working medium by radiating heat of the working medium flowing thereinto from the evaporator so as to recover exhaust heat on the coolant side. The condenser is located to return the condensed working medium to the evaporator.Type: GrantFiled: June 7, 2007Date of Patent: May 24, 2011Assignee: Denso CorporationInventors: Masashi Miyagawa, Yasutoshi Yamanaka, Koichi Ban, Kimio Kohara

Patent number: 7921640Abstract: An exhaust heat recovery heat exchanger assembly for use along a main exhaust flow path of an exhaust system for an engine, and a method of operation, is disclosed. The exhaust heat recovery heat exchanger includes a sealed vacuum chamber, including a hydride pellet mounted in the chamber, and electrical leads extending from the hydride pellet. An exhaust chamber along the main exhaust flow path is located along an inner wall of the vacuum chamber. A housing surrounds the vacuum chamber and defines a heat receiving medium chamber. A heat receiving medium flows through the heat receiving medium chamber and absorbs heat from the exhaust flowing through the exhaust chamber when an electric current is applied to the hydride pellet.Type: GrantFiled: December 14, 2007Date of Patent: April 12, 2011Inventor: Gregory A. Major

Patent number: 7908857Abstract: A turbo assembly may include a coupling member, a heat shield, and a turbo mechanism. The coupling member may include first and second ends and an annular body extending between the first and second ends. The first end may fix the coupling member to an exhaust manifold of an engine and the annular body may define an exhaust gas channel that receives exhaust gas from the exhaust manifold. The annular body may include a coolant passage that receives a coolant fluid. The heat shield may extend axially within the exhaust gas channel and radially between the annular body and an exhaust gas flow within the exhaust gas channel to limit an amount of heat transferred from the exhaust gas to the annular body. The turbo mechanism may include a housing fixed to the second end of the coupling member and in communication with the exhaust gas channel to receive the exhaust gas therefrom.Type: GrantFiled: May 8, 2008Date of Patent: March 22, 2011Assignee: GM Global Technology Operations LLCInventor: Eric A. Nordling

Patent number: 7856810Abstract: An exhaust cooling system of an amphibious vehicle operable in land and marine modes comprises an exhaust system to be cooled, at least one air-liquid heat exchanger, and coolant liquid in thermal communication with the exhaust system to be cooled and the air-liquid heat exchanger(s) and heated by the exhaust system. When the amphibious vehicle is operated, the coolant liquid is cooled by the air-liquid heat exchanger(s). Optionally, at least one liquid-liquid heat exchanger may be provided and the coolant liquid cooled by the liquid-liquid heat exchanger(s). The vehicle may plane, and have retractable road wheels. The air-liquid heat exchanger(s) may be mounted at the front or rear of the vehicle, or elsewhere.Type: GrantFiled: November 28, 2005Date of Patent: December 28, 2010Assignee: Gibbs Technologies LtdInventors: Simon James Longdill, Hans Weekers, Stephen John Briggs
