Patent number: 10746134Abstract: A water injection system for spraying water toward an intake system of an engine is disclosed. The water injection system includes a water collection circuit that has a water collection pipe for collecting water from the intake system and a drain valve installed on the water collection pipe. The water collection circuit collects water from the intake system of the engine by opening the drain valve when amount of stagnant water in the intake system reaches a predetermined threshold.Type: GrantFiled: November 29, 2017Date of Patent: August 18, 2020Assignees: HYUNDAI MOTOR COMPANY, KIA MOTORS CORPORATIONInventors: Suk Il Park, Jeong Hyun Na, Young Kyung Choi, Young Hwan Kim, Seung Il Moon, Jong Gyun Kim

Patent number: 10746135Abstract: Methods and systems are provided for taking mitigating action where a canister purge valve configured to control an amount of fuel vapors inducted into the engine during purging operations of a fuel vapor storage canister, is indicated as being degraded. In one example, a method comprises controlling an amount of pressure directed to a fuel tank and the fuel vapor storage canister via a pump positioned downstream of the fuel tank and canister to actively route fuel vapors to the canister during a refueling event. In this way, fuel vapors may be prevented from being routed to engine intake under conditions of a degraded canister purge valve, which may reduce opportunity for vehicle stall, improve driveability, and which may reduce release of undesired evaporative emissions to atmosphere.Type: GrantFiled: March 26, 2018Date of Patent: August 18, 2020Assignee: Ford Global Technologies, LLCInventor: Aed M. Dudar

Patent number: 10746137Abstract: A tank venting system for an internal combustion engine includes a tank, which is connected via a tank vent to a sorption reservoir for a temporary storage of fuel from a tank venting flow. A purge air pump is provided for feeding regenerated fuel from the sorption reservoir via a purge air flow into an intake air flow to the internal combustion engine. A controller is configured to control the purge air pump in such a way that the purge air flow can be adjusted with regard to its pressure, its mass and/or its volume, thus ensuring that a metering of the regenerated fuel via the purge air flow into the intake air flow takes place in accordance with an operating state of the internal combustion engine. A method for regenerating a sorption reservoir is also provided.Type: GrantFiled: January 19, 2018Date of Patent: August 18, 2020Assignee: Volkswagen AktiengesellschaftInventor: Jens Wodausch

Patent number: 10746138Abstract: An EGR cooler may include an EGR cooler housing having top, bottom and side walls, inlet and outlet end walls disposed at opposite ends, and a longitudinal axis extending in a direction of exhaust gas flow from the inlet end to the outlet end. A plurality of cooling tubes extend through the EGR cooler between the top and bottom walls, and are arranged in a cooling tube array to form an exhaust gas receiving area at an upstream side of the cooling tube array proximate the inlet end wall so that exhaust gas flowing into the EGR cooler through an exhaust gas inlet opening will flow into the exhaust gas receiving area and then disperse through the cooling tube array. A pitch distance between the cooling tubes may be greater proximate the longitudinal axis than proximate the side walls to promote flow through, instead of around, the cooling tube array.Type: GrantFiled: April 30, 2018Date of Patent: August 18, 2020Assignee: Progress Rail Locomotive Inc.Inventors: Sudarshan Kedarnath Loya, Steven D. Johnson, Vijaya Kumar, Laura Elise Rasmussen, Adarsh Gopinathan Nair, Michael B. Goetzke
