    摘要： Disclosed is an electronic controller for a diesel engine that includes a supply pump (2) for supplying fuel under pressure to a common rail (3) provided on a fuel supply line, the supply pressure level of the supply pump (2) being controllable, and a pressure reducing valve (7) for reducing the pressure of fuel in the common rail (3) (the rail pressure). The controller (10) automatically stops the engine when predetermined automatic stop conditions are satisfied during idling of the engine as well as restarts the engine when predetermined restart conditions are satisfied while the engine is at an automatic standstill. Furthermore, the controller (10) controls the supply pressure level of the supply pump (2) so as to make the rail pressure higher for the engine at an automatic standstill than a target value (PRidle) of the rail pressure during idling. The controller (10) also holds the pressure reducing valve (7) closed while the engine is at an automatic standstill and as well provides control to the degree of opening of the pressure reducing valve (7) so that when the engine is restarted, the rail pressure is at a target pressure (target rail pressure at restart) that is required for a restart.

    摘要： Disclosed is a control device of an internal combustion engine capable of improving emission characteristics of the internal combustion engine at the start-up. When an ECU for engine control controls injection during the exhaust stroke of a port-injection internal combustion engine, first fuel injection is carried out during a period t 1 to t 2 at a fuel-injection timing before actual stroke determination at the engine start-up as shown in, for example, FIG. 12(b) on the basis of a crank angle based on a memory, and the injected fuel is introduced to a cylinder during the actual stroke. If the fuel is not injected during a period of t 1N to t 3N of the subsequent exhaust stroke as indicated by a solid line, the cylinder blows out, and the rotation of the engine cannot be smoothed at the engine start-up. To avoid this, the ECU for engine control performs control such that the fuel injection can be carried out by clearing a flag (F_INJ) indicating completion of fuel injection as indicated by an alternate long and short dash line at a timing t JUD of determining a memory lapse in the crank angle.
