A fuel pump has a pump chamber accommodating a rotor member. The rotor member is rotatable to supply fuel to from a tank to an exterior of the tank. A case is supported in the tank. The case accommodates a part of the fuel pump. A pump bracket is located in the tank. The pump bracket is in a tubular bottomed shape having a sidewall portion in which a remaining portion of the fuel pump is inserted such that the sidewall portion surrounds a radially outside of the pump chamber of the remaining portion. The pump bracket is joined with the case to define a gap therebetween in a radial direction of the rotor member such that the pump bracket is movable relative to the case.

Variable flow fuel transfer pump system and method

Номер: US20120073545A1

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.

Filter element using plastic cap integrated with relief valve

Номер: US20120193275A1
Автор: Jang Soo Kim
Принадлежит: Individual

The present invention relates to a filter element using a plastic cap integrated with a relief valve, wherein a net type core 21 is received in a spin-on filter housing 10 in the cylindrical shape opened at the top portion thereof and formed with a plurality of oil passing holes 21 a in the periphery thereof, and an oil pleated paper 22 is positioned to maintain the shape thereof at the periphery of the core 21 so as to be positioned at a small distance from the inner wall of the housing 10. The filter element 20 includes: an upper cap 23 formed of a plastic material at the upper end thereof; and a fixed lower cap 50 integrated with a relief valve formed of plastic material at the lower end thereof. The fixed lower cap 50 integrated with a relief valve receives and fixes a relief valve 30, which is formed of a valve plate 32 and an elastic spring 33. In the filter element 20, the core 21 is covered by the upper cap 23 and the lower cap 50, which are kept in close contact with the outside of the core 21. According to the present invention, assembly of the valve plate 32 and the elastic spring 33 of the relief valve 30 is simplified by integrating a plurality of upper holding protrusions 52 of the fixed lower cap 50 integrated with a relief valve. In addition, the deviation of an element compression spring 25 closely contacting the lower inner surface of the housing 10 by the oil which is introduced into an oil hole 53 is prevented by the integration of the lower holding protrusions 52. Furthermore, the upper cap 23, the fixed lower cap 50 integrated with a relief valve and the core 21 are manufactured by plastic injection molds so as to reduce weight. The spin-on filter may be reused without separation from the oil pleated paper 22, which is fixed by a thermosetting resin 22 a (since both are formed of the same materials) when discarding the spin-on filter. In addition, it is possible to use the element in the generation of renewable energy.

A fuel injection control device learns a port injection learning value and a direct injection learning value separately for each of learning regions that are divided according to the engine operating state. It is assumed that a port injection learning condition and a direct injection learning condition are both satisfied in a learning region in which neither the learning of the port injection learning value nor the learning of the direct injection learning value has been completed. In such a situation, the fuel injection control device executes the port injection learning process if the ratio of the port injection amount is less than the ratio of the direct injection amount, and executes the direct injection learning process if the ratio of the direct injection amount is less than the ratio of the port injection amount.

A lower limit setting portion of a fuel pump control system sets a lower limit value depending on an engine operating mode. For example, it sets a duty ratio of 0% as the lower limit value, when the engine operating mode is in a STOP mode in a turned-on condition of an ignition switch. A duty-ratio calculating portion carries out a feedback control in order that an actual fuel pressure comes closer to a target fuel pressure by use of the lower limit value and calculates a duty ratio for driving a fuel pump by the feedback control. An abnormal condition determining portion determines an abnormal condition based on the duty ratio and pump current. The abnormal condition determining portion further determines based on a remaining fuel amount whether the abnormal condition is caused by a disconnection or whether the abnormal condition is caused by an idling operation of the fuel pump due to fuel shortage. 1.

Various methods and system are described for a fuel system which includes a fuel composition sensor and a fuel lift pump disposed upstream of the sensor. The system may be operated in each of three different modes of operation. In each of the modes, a fuel lift pump voltage is adjusted responsive to a fuel capacitance output by the sensor, while a variable such as sensor temperature or fuel pump pressure is maintained depending on the mode of operation. 1. A method for a gasoline direct injection engine system , comprising:operating a fuel lift pump at a pressure within a threshold range above a fuel vapor pressure, the vapor pressure based on fuel capacitance.2. The method of claim 1 , wherein the fuel capacitance is measured via a fuel composition sensor.3. The method of claim 1 , wherein the fuel capacitance is measured via a higher pressure pump claim 1 , the higher pressure pump operating at a higher pressure than the fuel lift pump and disposed downstream of the fuel lift pump along a fuel passage.4.

Water Drainage Device, Filter Module, and Method

Номер: US20220290640A1
Автор: Martin Weindorf, Rafael Salom
Принадлежит: Mann and Hummel GmbH

A water drainage device for a filter module is provided with a valve housing that has a valve bore, a valve body received at least in sections in the valve bore, an actuation rod for actuating the valve body, and a coupling device operatively connecting the actuation rod with the valve body and enabling a tilting of the actuation rod in relation to the valve body. The water drainage device can be transferred from a closed state, in which the valve body seals in relation to the valve seat of the valve bore, into an open state, in which the valve body is lifted off the valve seat, and in reverse. The filter module has a filter housing with a housing top part. The valve body, upon transfer of the water drainage device from closed state into open state, moves toward the housing top part of the filter housing.
