Abstract (en)
The control device uses a decompression valve (3) moved into an open or closed position, via an operating piston, during the compression stroke of the reciprocating piston used to compress the air within the engine cylinder. The pressure required to open the decompression valve (3) is provided by a high pressure fuel pump (16), with the air extracted from the cylinder fed to an exhaust gas line (4) or a pressurised air reservoir (10), the pressurised air feed to which is selectively controlled via a solenoid (14) which is controlled by an electronic control unit (15) e.g. of the engine electronics. Pref. the decompression valve is incorporated in the cylinder head in addition to the gas exchange valves
Abstract (de)
Eine Vorrichtung dient zur Steuerung von in einem Zylinder einer Brennkraftmaschine durch einen Kolben komprimierter Luft mittels eines Dekompressionsventils (3), das von einer Steuereinrichtung (15) in einem Verdichtungshub des Kolbens in eine Öffnungs- oder Schließstellung verstellbar ist. Die über das Dekompressionsventil (3) dem Zylinder entnommene Luft ist in eine Abgasleitung (4) oder einen Druckluftspeicher (10) abführbar. Der zum Öffnen des Dekompressionsventils (3) notwendige Druck ist mittels einer Hochdruckpumpe (16) erzeugbar. <IMAGE>
