The engine ECU executes a program including the step of detecting an engine coolant temperature, the step of detecting an engine speed and an engine load, the step of estimating a temperature at a tip end of an in-cylinder injector based on the engine coolant temperature, the engine speed and the engine load, and, when the temperature at the tip end is greater than a guaranteed temperature, the step of calculating a drive duty of a high-pressure fuel pump that ensures a decrease of the temperature at the tip end of the in-cylinder injector to the guaranteed temperature, and the step of controlling the high-pressure fuel pump using the drive duty.

Fuel supply apparatus for internal combustion engine

A fuel supply device is obtained in which joint strength can be maintained in a joint portion of plural filter members configuring a fuel filter. A fuel filter with an overall bag shape is configured by welding together an upper face filter cloth a lower face filter cloth of the fuel filter at a welded portion. A sub tank upper side member and a sub tank lower side member nip the upper face filter cloth and the lower face filter cloth at a nipping position that is at a different position from the welded portion.

Fuel supply device

The invention relates to a fuel-injection valve comprising a valve body (1), on whose combustion chamber end a pressure chamber (26) that is connected to a supply channel (7) is configured. The pressure chamber (26) is delimited by a valve member (20), whose valve sealing surface (18) lies by means of residual stress against a fixed valve seat (17) and which can be lifted up from the latter by the pressure in the pressure chamber (26). At least one injection opening (12) into the combustion chamber of the internal combustion engine is located downstream of the opening cross-section obtained by the lifting of the sealing surface. The valve member (20) has an essentially disc-shaped configuration and the valve sealing surface (18) is configured on the radially outlying peripheral area of said member and can be lifted up from the valve seat (17) in a resilient manner. The central section of the valve member (20) is pretensioned by a single retaining element (22) on the valve body (1) in relation to the resting position of said member against the valve seat (17).

Fuel injection valve for internal combustion engines

The invention relates to a pressure-controlled fuel-injection device (1). Said device comprises a common pressure accumulation chamber, one injector (3) per cylinder and a local pressure intensifier (4) that is allocated to each injector (3). A 2/2-way valve (14) is provided for metering fuel to the injector (3).

Fuel injection device

Various embodiments of the invention provide human proteins associated with cell growth, differentiation, and death (CGDD) and polynucleotides which identify and encode CGDD. Embodiments of the invention also provide expression vectors, host cells, antibodies, agonists, and antagonists. Other embodiments provide methods for diagnosing, treating, or preventing disorders associated with aberrant expression of CGDD.

Proteins associated with cell growth, differentiation, and death

During a transitional operation of an engine in which an engine load is changed suddenly from a high load to a low load, a control operation for extending an opening period of a change-over valve which is adapted to switch a low-pressure accumulator and a high-pressure accumulator from one to the other during a fuel injection operation is carried out to increase a flow rate of a fuel supplied to the low-pressure accumulator and thereby reduce the pressure in the high-pressure accumulator, whereby a response delay of the fuel pressure in the high-pressure accumulator is minimized. During a transitional operation of the engine in which the engine is in an accelerated operation, the change-over valve is kept open until the fuel pressure in the low-pressure accumulator, which is connected to the portion of a fuel passage which is on the downstream side of the change-over valve adapted to switch the low-pressure accumulator and high-pressure accumulator from one to the other during a fuel injection operation, reaches an indicated level, and until a predetermined period of time elapses after the fuel injection finishing time, whereby the formation of a fuel pressure in the low-pressure accumulator is promoted to obtain injection condition suiting the operating condition of the engine.
