摘要:
The present invention provides a DPF failure detection method and a DPF failure detection device, which can be realized with a simple configuration and detect a failure at low cost. The theoretical deposited amount of PM on a DPF 4 is calculated from the operating state of an internal combustion engine 2. The actual deposited amount of the PM on the DPF 4 is measured based on the electrical capacitance of an electrical capacitance type PM sensor 6. When the divergence of the actual deposited amount from the theoretical deposited amount exceeds an allowable limit, it is determined that the DPF 4 has a failure.

The present invention provides a disk player which includes a switch for detecting that a pickup is positioned for reading signals as opposed to the middle position between a content signal recording area and a reference information recording area. The pickup is moved to an inner periphery of the disk for a predetermined period of time from the time of detection detected by the switch, upon a command given to read information from the reference information recording area. Then the pickup is restrained from moving further by a stopper, upon the pickup reaching the position opposed to the reference information recording area.

In an electronically controlled hydraulic actuation type fuel injection device, a viscosity value (mu) of hydraulic oil is detected by an oil viscosity detection sensor and then an aimed base valve opening time T.sub.injBASE during which a solenoid valve of a unit injector to be kept open is corrected based on the detected viscosity value. Lubricating oil for lubricating an engine is used as the hydraulic oil. The oil viscosity detection sensor includes an oil pump for supplying the lubricating oil to each sliding part of the engine and an oil sensor for detecting a delivery pressure Po of the oil pump. All of the sliding parts of the engine is regarded as one "throttle" and the viscosity (mu) of the hydraulic oil is determined according to a pre-prepared map from the engine speed Ne and the delivery pressure Po, utilizing change in passage resistance at the "throttle" caused by oil viscosity change. This oil viscosity detection device and the oil viscosity detection method utilizing that device can be easily added to every conventional engine as an option.
摘要:
In this fuel injector for internal combustion engines, a pressure chamber is provided at an end portion of a pressure increasing piston which is adapted to increase the pressure of a fuel in a pressure increasing chamber, and a hollow portion which is on the back side of the pressure increasing piston is opened to the atmospheric air through communication ports formed in an injector body. The pressure increasing piston comprises a small-diameter portion of a plunger which defines a part of the pressure increasing chamber, a large-diameter portion of a piston which defines a part of the pressure chamber, and a guide ring portion extending downward from the whole circumference of the large-diameter portion and forming a sliding surface with respect to a hollow. The hollow portion is provided with a return spring for biasing the pressure increasing piston toward the pressure chamber. Since the hollow portion of this fuel injector is opened to the atmospheric air, the resistance to the vertical movement of the fuel pressure increasing piston is eliminated, and the responsiveness of the needle valve is improved.
