摘要： A diesel engine control system and control method capable of conducting accurate fuel injection unaffected by variations in injector performance caused by differences among individual injectors or change with aging. The diesel engine control system includes an injector for directly injecting fuel into a combustion chamber of a diesel engine, injection quantity controller for controlling fuel injection quantity by varying a period of electric current supply to the injector, estimator for estimating that an electric current supply period when a prescribed (stable) combustion state is obtained is the current supply period for injecting the amount of fuel required for the prescribed combustion state, and control data correcting device for correcting control data of the injection quantity controller based on the estimated current supply period.

摘要： A vacuum chamber-forming method for forming a vacuum chamber in a power element of a control valve for a variable capacity compressor through a reduced number of steps. A power element is assembled in the atmospheric air by arranging a disk, a diaphragm, a disk, a spring and an upper housing on a lower housing, caulking the periphery of the lower housing to the periphery of the upper housing, and then soldering the junction of the upper and lower housings. The assembled power element is placed in a vacuum container, and a small hole formed in the upper housing is subjected to spot welding in the vacuum atmosphere, whereby the small hole is sealed by a weld metal.
