Abstract:

A filter within a filter cartridge design is described that includes a sealing structure on an endplate of an outer filter element. Generally, the sealing structure includes an annular flange on the endplate that can directly seal against an interior surface of a housing when the filter cartridge is assembled for use. During filtration, the annular flange prevents a working fluid from bypassing the outer filter element. The sealing flange can seal with the housing in a press fit engagement.

International Classification:

F02M 53/02
F02M 55/02

US Classification:

123468

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. The method includes circulating heated fluid in a continuous low pressure circuit to heat fuel present in a high pressure fuel line if the sensed fuel temperature is less than or equal to a predetermined value, and evacuating fluid for heating fuel from a portion of the continuous low pressure passage and fluidly connecting the evacuated portion of the continuous low pressure passage to a fuel leakage detection device if the sensed fuel temperature is greater than the predetermined value.

International Classification:

US Classification:

123497

Abstract:

A fuel supply system and method of controlling fuel flow through a supply system is provided including a variable flow, i.e. speed, electric fuel transfer pump and a control system adapted to variably control the transfer pump based on fuel demand of the engine. The system provides improved transient response by providing the transfer pump with a feed forward speed/flow command based on engine fueling demand determined based on engine operating conditions. The transfer pump is controlled based on fuel demand not necessarily achieved yet by the high pressure pump and injectors. Therefore, this system controls the EFTP substantially simultaneously with controlling the high pressure pump and injectors to optimize fuel flow through the entire system ensuring the minimum required fuel flow is passing through the second the fuel filtration system, hence maximizing steady state fuel filtration efficiency, and minimizing surge effects on filtration efficiency.
