    摘要： An electronic control unit (51) sets a split injection region in which fuel injection is divisionally performed by performing main injection and pilot injection, and an injection stop region in which fuel injection is stopped, in accordance with operational conditions of a diesel engine (1), and performs fuel injection control based on the opening and closing operation of the electromagnetic valves (3) of injectors (2). A boundary region in which only the pilot injection with an effective amount of injection secured is performed is set in a region between the split injection region and the injection stop region. This region setting avoids execution of only the main injection in a state where the pilot injection is not performed and therefore a suitable combustion environment is not secured.

    摘要： A hydrostatic power steering system is provided of the type including a steering control unit (3) operated by an input such as a steering wheel (1) to control flow from a source (8) to a steering cylinder (7). The source is operated in response to an electrical signal from a controller (82), controlled by a sensed pressure at a pressure detection port (64). The pressure at the port (64) is communicated from the main fluid path of the steering control unit (3), downstream of the fluid meter (18) when the spool (21) and sleeve (22) are relatively displaced. In systems in which the system reservoir (R) is at an elevated ("regulated tank") pressure, the pressure detection circuit is drained through a variable orifice (70) to a drain port (66), which is in communication with a sump (S) maintained at substantially atmospheric pressure. As a result, the steering system responds at a lower steering pressure, and the initial steering is smoother.
