摘要: An injection system provides an intermittent supply of fuel mixture into combustion spaces of an internal-combustion engine. The system includes a valve and a pipe by way of which a control space in the injection valves may alternatively be acted upon by a pressure. The control space is formed by a valve member and a piston. A first pressure spring presses the valve member onto an injection opening, and a second pressure spring presses the piston away from the injection opening.

摘要: Injection system for the intermittent introduction of a fuel-liquid mixture into the combustion spaces of an internal-combustion engine with a common-rail pressure reservoir. Lines (16, 30) lead to control spaces (15, 22) of control valves (1). Control space (15) is joined selectively with the common-rail pressure reservoir or a line (18) with a pressure p0 or a line with a pressure p1 for control of injection quantities of the fuel-liquid mixture. Control space (22) is joined selectively to the common-rail pressure reservoir or to a line with pressure p2 or to a line (33) with pressure p0 for control of the liquid fraction of the injection quantity.
