摘要： PROBLEM TO BE SOLVED: To provide a fuel injection quantity control device performing learning control of fuel injection quantity capable of defining an appropriate learning value for fuel injection pressure over a wide range, especially for high fuel injection pressure while eliminating driver's sense of incongruity due to combustion noise generated at a time of learning control, and an internal combustion engine provided with the control device.
SOLUTION: The fuel injection quantity control device performs single injection for learning control after raising rail pressure to a learning subject rail pressure higher than the current rail pressure by driving a high pressure fuel pump 4 (ST4) if background noise (engine noise and road noise) is relatively high (ST2, Yes) when pilot injection quantity learning control execution conditions are satisfied. On the other hand, the fuel injection quantity control device performs single injection for learning control after the rail pressure drops to the learning subject rail pressure lower than the current rail pressure if background noise (engine noise and road noise) is relatively low.

摘要： PROBLEM TO BE SOLVED: To provide an intake throttle-valve control system of a diesel engine by which an engine output enough to continue operation of the engine can be ensured without providing a particular constitution.
SOLUTION: In the control-system, a valve-travel (a valve-travel VA) of the intake throttle-valve is detected by a valve-travel sensor. In order to cause the valve-travel VA to agree with a command valve-travel, a feedback control is performed by controlling an electric motor for opening/closing the intake throttle-valve on the basis of the detected valve-travel VA. If the valve sensor is determined to be faulty, the feedback control is disabled, and the electric motor is forcedly driven (time t1-t5) so that the valve travel VA is maintained at least at a specified valve-travel.

摘要： PROBLEM TO BE SOLVED: To prevent the erroneous crank angle from being detected caused by the pulse cracking phenomenon to be generated caused by opening of a spill valve, concerning an electronically controlled diesel engine provided with the spill valve. SOLUTION: In the case of the engine speed NE is being low, if internal pressure in a pump chamber is steeply decreased with closing of a spill valve, torsion generated on a driving shaft of a fuel pump is steeply released. When a pulsar of a rotational angle sensor is temporarily rotated at high speed with releasing, excess pulses are generated from an electromagnetic pickup sensor. When such the situation is detected (a step 200), the execution of detecting of a chipped signal and the execution of NE calculating are prohibited (a step 202).

摘要： PROBLEM TO BE SOLVED: To provide a fluid pump suitable for a fuel high pressure injection pump of a diesel engine by preventing abnormal wear or seizure in a sliding part between the cam and the plunger. SOLUTION: In this fluid pump with a plunger operated by a cam mechanism, the cam mechanism consists of a cam, a roller which slidingly contacts with the cam, and a shoe which slidingly contacts with the cam and abuts on the plunger. Either of the roller or the shoe is made of ceramics with coefficients of thermal expansion nearly equal to that of the other part. For example, one part is made of a ferrous metal, while the other part is made of zirconia ceramics. In the fluid pump having the same structure as the above, at least one of the roller and the shoe is made of silicon nitride ceramic or silicon carbide ceramic. Both ends of the roller are formed into a crown shape, so that the variation of the surface pressure caused by sliding contact between the roller and the cam, in the longitudinal direction of the roller lies in a prescribed range.
