摘要： Provided are a pressure sensor diagnosis method and a common-rail-type fuel injection control device which can realize the diagnosis of the presence or the non-presence of abnormality of a pressure sensor with the simple constitution without having a dedicated circuit for diagnosis of an operation such as abnormality or a malfunction of the pressure sensor. A time from a point of time that energizing of injectors 2-1 to 2-n is finished to a point of time that a peak of a counter electromotive current generated in the injectors 2-1 to 2-n is generated after the finishing of the energizing is measured as a valve closing time (S504 to S516). A rail pressure with respect to the measured valve closing time is obtained as an estimated rail pressure Pv based on a correlation acquired in advance between a valve closing time and the rail pressure (S520). When an absolute value of the difference between the estimated rail pressure Pv and an actual rail pressure Pac acquired by a pressure sensor 11 is equal to or less than a predetermined error ±, it is determined that the pressure sensor 11 has no abnormality (S524), while when the absolute value is not equal to or less than a predetermined error ±, it is determined that the pressure sensor 11 has abnormality (S526).

摘要： The objective of the present invention is to dampen operating sounds of an electromagnetic drive mechanism used for a variable displacement control mechanism in a high-pressure fuel supply pump to reduce an individual difference depending on apparatus due to the change over time or installation tolerance.
To achieve the above objective, the present invention is configured such that before the electromagnetic drive mechanism supplies a drive force to a plunger (31a, 31b) which is electromagnetically driven by the electromagnetic drive mechanism, another displacement force situates the plunger (31a, 31b) in a specific position. When compared to an occasion where the plunger (31a, 31b) is displaced all strokes by a magnetic biasing force, the above configuration is able to reduce the force of impact on a member (for example, valve body) mounted to the plunger (31a, 31b) and a restricting member (35), thereby damping the collision noise. Furthermore, since an extra member, such as a damping member, is not required, individual difference depending on apparatus do not easily occur.

摘要： The invention provides a high-pressure fuel supply pump including an intake channel (10) through which fuel is taken into a pressure chamber (11), a discharge channel (8, 12) through which the fuel is delivered from the pressure chamber (11), and a plunger which reciprocates in the pressure chamber (11) draws and discharges the fuel, and the intake channel (10) has an electromagnetic intake valve (30) and the discharge channel (8, 12) has a discharge valve (8b), and the amount of fuel delivered is controlled by connecting and disconnecting the intake channel (10) to the pressure chamber (11) by opening and closing the electromagnetic intake valve (30). The electromagnetic intake valve (30) is an electromagnetic drive mechanism comprising an intake valve operated by a magnetic biasing force, the electromagnetic drive mechanism which opens the intake valve and keeps it open by means of the magnetic biasing force, a restricting member (35) for restricting, in a specific position, the displacement of the intake valve when it opens, and a biasing member (33) for biasing the intake valve in the direction of closing the valve, wherein when the electromagnetic drive mechanism is turned off, the intake valve is displaced in the direction of opening the valve due to a fluid differential pressure between the intake channel side pressure and pressure chamber side pressure of the intake valve.
