Publication number: 20230091244Abstract: A hydrogen fuel tank mounting system for a vehicle comprises a first mount for mounting a first portion of the fuel tank in a fixed position and a second mount for slidably mounting a second portion of the fuel tank. In this manner, the mounting system reduces stress on fuel system components when accommodating expansion and contraction of the hydrogen fuel tank, improving durability. The fuel tank may be a dual port fuel tank, and the first and second portions may be elongated neck portions. The fixed mount may be a bracket formed in two portions with a clearance between them. A sleeve may extend through at least part of the portions of the brackets to distribute shear forces away from an interface between those portions. The provision of a slidable mounting also allows pre-assembly of the fuel tank and mounts, facilitating installation of the hydrogen fuel system.Type: ApplicationFiled: September 21, 2022Publication date: March 23, 2023Inventors: Khizer Tufail, Guenter Grosch, Krystian Dylong, Rainer Kiehn, Klaus-Peter Heinig, Mauro Giroldo, Bert Hobein

Patent number: 10131344Abstract: A hybrid vehicle and method for reducing fuel consumption include upper and lower engine speed limits set based upon whether the state of charge of a battery electrically connected to an electric machine, which may be implemented by an integrated starter-generator is sufficiently high to permit the electric machine to provide a temporary torque boost to an engine of the motor vehicle. If the state of charge of the battery is sufficiently high to permit temporary torque boosting, then the upper and lower engine speed limits are reduced from baseline upper and lower limits to adjusted upper and lower limits to reduce fuel consumption of the engine without adversely affecting NVH.Type: GrantFiled: February 22, 2016Date of Patent: November 20, 2018Assignee: Ford Global Technologies, LLCInventors: Anthemios Philemon Petridis, Nicholas Dashwood Crisp, Khizer Tufail

Patent number: 9909515Abstract: A method is disclosed for operating an internal combustion engine in which a coolant temperature of an engine coolant of the internal combustion engine is determined and is compared with a predetermined threshold temperature. If the coolant temperature is higher than the predetermined threshold temperature, a thermal input into the engine coolant is reduced by changing at least one operating parameter of the internal combustion engine. This can be done, for example, by raising a charging pressure of the internal combustion engine.Type: GrantFiled: July 10, 2014Date of Patent: March 6, 2018Assignee: Ford Global Technologies, LLCInventors: Bernd Brinkmann, Khizer Tufail, Alain Evrard, Matthew Barber, Slavenko Vukovic, Ralph Maiwald, Paul Crossley

Patent number: 9316137Abstract: A method of operating a diesel engine 10 having LNT 11 and SCR 13 aftertreatment devices arranged in series to receive exhaust gas from the engine is disclosed in which the engine is operated in a rich early injection mode to generate ammonia in the LNT for storage in the SCR located downstream from the LNT. This reduces the amount of soot produced permitting longer operation of the engine in rich early injection mode and further may reduce the use of PGM material in the LNT and increase the amount of ammonia for use in the SCR.Type: GrantFiled: December 12, 2013Date of Patent: April 19, 2016Assignee: Ford Global Technologies, LLCInventors: Khizer Tufail, Mark Stephen Brogan, Haiwen Song, Martin John Ledger, Peter Graham Eastwood
