  • Publication number: 20140311454
    Abstract: A method is described for adjusting the amount of gaseous fuel injected based on the sonic choked flow rate through a restriction. Because the sonic choke flow rate continues to decrease as tank pressure decreases, the method includes computing the sonic choke flow rate through the restriction based on system variables and enforcing the rate of CNG injection to be less than the sonic choke flow rate through the restriction. Thereby, the mass flow rate to the fuel injector can be substantially maximized to substantially minimize the time for fuel tank emptying, particularly during the last amount of tank emptying when the contents of the gaseous storage tank is low.

  • Patent number: 8733324
    Abstract: This disclosure relates a system for heating fuel supplied by a common rail fuel supply to an internal combustion engine. The system includes a high pressure fuel line, plural fuel injectors connected in series along the high pressure fuel line in the common rail, and a continuous low pressure passage including a heat exchanging portion in close proximity to the high pressure fuel line. A heated fluid source is operative to fluidly communicate with the continuous low pressure passage and circulate heated fluid to heat fuel present in the high pressure fuel line prior to, and during a cold start operation of the internal combustion engine. Other embodiments relate to a method of providing fuel to an internal combustion engine that includes sensing the temperature of fuel supplied to a fuel system and determining whether the sensed fuel temperature is greater than a predetermined value.

  • Patent number: 8720418
    Abstract: The invention relates to a fuel injection system of the common rail type having a rail body comprising a central bore and one or more outlet bores in fluid communication with the central bore for communicating with a respective fuel injector. The outer circumference of the rail body is substantially oval in cross-section and is thicker in cross-section in a direction substantially perpendicular to the outlet bore axis as compared to the thickness in cross-section substantially parallel to the outlet bore axis. By increasing the thickness of the rail body in this way, stresses at the intersection of the intersection of the central bore with the outlet holes may be reduced by up to 10% or more, thereby increasing the acceptable cycled running pressure of the system.
