Abstract: The technique of the present invention produces a first fuel-air mixture containing a first fuel and the air at a specific ratio, which does not allow for auto ignition of the first fuel-air mixture by simple compression, in a combustion chamber. The technique then injects a second fuel, which has a higher octane value than that of the first fuel, into a partial area of the combustion chamber, so as to produce a second fuel-air mixture. The technique ignites the second fuel-air mixture for combustion, so as to compress and auto-ignite the first fuel-air mixture. The second fuel has the higher octane value, so that a combustion start timing of the second fuel-air mixture is reliably regulated by ignition. Namely the technique positively controls the timing of auto ignition of the first fuel-air mixture. Setting an adequate value to the ignition timing thus effectively prevents the occurrence of knocking.

Abstract: In common rail fuel injection systems, a sensed rail pressure is used to determine control signals to produce desired injection characteristics. Because rail pressure fluctuates, especially during cold start procedures, and because the rail pressure must be sensed before the injection event to be controlled, the accuracy of the timing and quantity of the injection event can be compromised if the rail pressure at the start of the injection event is different from the sensed rail pressure. In order to produce more accurate fuel injection characteristics, the rail pressure is sensed after the end of control signal for an immediately preceeding injection event but at least a predetermined time before the start of control signal for a succeeding injection event.

Abstract: A no-return loop fuel injection system supplies fuel from a fuel pump to an injector fuel rail, through a fuel line. A biased closed pressure control valve communicates with the fuel line and has a valve head preferably of a diaphragm type carrying a fuel side having first and second areas which are segregated and defined by a valve seat when the pressure control valve is closed. An opposite second side of the pressure control valve is exposed to a reference pressure and a closure biasing force. The pressure control valve opens when a hydraulic opening force induced by a fuel pressure exerted upon the first area, plus a fuel pressure exerted upon the second area, is greater than the net reference pressure and closure biasing forces. Preferably, the first area is smaller than the second area, thus manipulating the effects of the fuel pressures exerted upon the first and second areas with respect to opening the valve.
