摘要： In order to calculate an estimation of the quantity of accumulated particulates in a filter (32), a first estimation calculation unit (100) that outputs first estimation data (XA) calculated from the filter before and after differential pressure, and a second estimation calculation unit (110) that outputs second estimation data (XB) based on the engine operation status. Of the first and second estimation data (XA, XB), the estimation data having the higher dependability, as viewed from the engine speed at that time, is selected, whether or not to regenerate the filter is determined and with the differential between the first and second estimation (XA, XB) also taken into consideration, when the differential is larger than a prescribed value, even if the engine speed is high, the first estimation data XA is not selected since there is a risk that the dependability of the estimation value is low due to cracking of the accumulated particulates.

摘要： In a state in which a high-pressure control solenoid valve is driven to control the pressure in a common rail (refer to Step S100), when the pressure in the common rail exceeds a predetermined value (refer to Step S104), a driving current determined by a prescribed value map that defines the correlation between the pressure in the common rail and the driving current of the high-pressure control solenoid valve is corrected based on an actual pressure in the common rail and the driving current of the high-pressure control solenoid valve at the actual pressure (refer to Steps S106, 108, S110, 112). The corrected driving current is passed to the high-pressure control solenoid valve, thereby ensuring appropriate and stable injection control even when there exists a variation in operational characteristics among pressure control valves.

摘要： A fuel feed pump is provided that has a fuel flow-rate regulating valve, on the inlet side. The fuel flow-rate regulating valve includes a housing with a fuel inlet port and a fuel outlet port, a valve mechanism for controlling the flow rate of the fuel from the inlet port to the outlet port, and a regulating mechanism for regulating a backpressure to control the position of a needle valve of the valve mechanism in response to a system pressure, to thereby control the flow rate by controlling the fuel flow through an opening provided in a valve chamber. This arrangement makes it difficult for contamination to accumulate, and also enables a low-cost implementation.

摘要： In a negative pressure boosting device of the present invention, upon depression of a pedal at a normal speed, an input shaft 11 and a valve plunger 10 move forward to close a vacuum valve 15 and open an atmospheric Valve 16 and a power piston 5, a valve body 4, and an output shaft 24 move forward. In the initial stage of operation, hooks 27c and 31a are not engaged with each other so that a cylindrical member 27 does not move forward, thereby shortening the stroke of the input shaft 11 as compared to a conventional one. Upon rapid depression of the pedal, a press face 10a presses a pressed face 27e so as to deform an engaging arm portion 27b, thereby disengaging the hooks 27c and 31a from each other. The cylindrical member 27 is moved backward by a spring 30 to push a vacuum valve portion 12b so that the atmospheric valve portion 12a is spaced apart from the atmospheric valve seat 14 more rapidly than that of the service braking, thereby increasing the jumping amount and thus rapidly intensifying the output.

摘要： An existing diesel engine vehicle of light oil fuel is enabled to run as a diesel engine vehicle using DME as fuel without exchanging a whole diesel engine and at very low cost and easily. The shape of a tip part 21 of a needle valve 2 is set by a center diameter L3 for regulating a minimum flow path area at full lift of a fuel injection nozzle 1, a seat diameter L2 of a seat part 211 coming in contact with a valve seat part 33 and blocking communication with a fuel injection hole 31, and a shaft diameter L1, and a tip end angle is about 92 degrees. The center diameter L3 is set to φ2.5 mm, the seat diameter L2 is set to φ3.0 mm, and the shaft diameter L1 is set to φ3.25 mm. The ratio of the center diameter L3 and the seat diameter L2 is L3/L2=2.5 mm/3.0 mm=about 0.833, and the ratio of the seat diameter L2 and the shaft diameter L1 is L2/L1=3.0 mm/3.25 mm=about 0.92.

摘要： Since an aspirator 7 is disposed at a position lower than a fuel gallery 11 and an overflow fuel pipe 81, DME fuel remaining in the fuel gallery 11 and the overflow fuel pipe 81 can be more efficiently retrieved to a fuel tank 4 by a combined force of gravity and suction force produced in a suction port 7c of the aspirator 7. Since the vapor-phase pressure delivery pipe opening/closing solenoid valve 74 is disposed at a position higher than the fuel gallery 11, DME fuel in a liquid state remaining in the fuel gallery 11 and the overflow fuel pipe 81 is forcedly delivered under pressure to the suction port 7c of the aspirator 7 by a combined force of gravity and the pressure of a vapor phase 4b in the fuel tank 4. Accordingly, time taken to retrieve the DME fuel in an injection system to the fuel tank after the stop of a diesel engine.

摘要： A receiving portion 2e for rotatably receiving therein a planetary gear 3, is formed between a plurality of retaining protrusions 2d of a carrier. A connection portion 2f extending annularly about a rotation axis L is formed on an outer peripheral of a distal end portion of each retaining protrusion 2d. Through this connection portion 2f, the distal end portions of the respective retaining protrusions 2d are connected to each other. Owing to this arrangement, each retaining protrusion 2d is reinforced to minimize its deformation. As a result, deformation of the receiving portion 2e is greatly reduced and the planetary gear 3 receiving in the receiving portion 2e can rotate smoothly.
