Publication number: 20110023832Abstract: A fuel system for a diesel engine has both a low pressure pump, which extracts fuel from the fuel tank, and a high pressure pump, which is fed by the low pressure pump and supplies fuel to fuel injectors. The fuel injectors supply fuel to the engine cylinders, with a small portion of fuel routed back into the fuel system. According to an embodiment of the present disclosure, the injector return fuel is routed into a low pressure fuel line between the low and high pressure fuel pumps, with return fuel from the fuel rails returned through a fuel cooler to the fuel tank. The low pressure fuel line has a filter disposed therein and the injector return fuel is returned to the low pressure fuel line upstream of the filter.Type: ApplicationFiled: July 30, 2009Publication date: February 3, 2011Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Bradley Allen Brown, Larry Castleberry, Brien Lloyd Fulton, Scott James Szymusiak

Publication number: 20110023819Abstract: A four-valve per cylinder engine has two intake valves, two exhaust valves and a centrally located fuel injector. Between each adjacent pair of valves is a valve bridge with a point of minimum separation between adjacent valves. In the present disclosure, the glow plug port is defined in the cylinder top at a location outboard of the minimum separation between adjacent and at a depth which is tangent to an edge of a fuel jet emanating the injector. By placing the glow plug farther outboard than found in the prior art, the glow plug contacts the fuel as it comes out of the injector and as it rebounds off a feature of the piston bowl.Type: ApplicationFiled: July 31, 2009Publication date: February 3, 2011Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: David Curtis Ives, Brien Lloyd Fulton, Eric Matthew Kurtz, Bradley David Opperman, Joshua Putman Styron, Patrick Brian Morgan, Martin Johannes Atzwanger

Patent number: 6868328Abstract: A method and system for controlling fuel for an internal combustion engine. Two fuel demand signals are provided, one from an idle speed fuel controller (i.e., a base fuel demand signal) and one from pedal position (i.e., an unmodified pedal fuel demand signal). The pedal position signal is a function of engine speed and actual pedal position. A modified pedal position fuel demand signal is produced. The modified pedal fuel demand signal is equal to the unmodified pedal fuel demand increased by a bias value. The bias value is a predetermined offset, or hysteresis value, from the base fuel demand signal. The actual fuel supplied to the engine is equal to the greater of the base fuel demand signal and the modified pedal fuel demand signal. With such method, the amount of dead pedal time delay is reduced.Type: GrantFiled: June 26, 2003Date of Patent: March 15, 2005Assignee: Ford Global Technologies, LLCInventor: Brien Lloyd Fulton
