Patent
Fuel injection apparatus for internal combustion engines
TL;DR: In this article, the authors describe a fuel injection apparatus for internal combustion engines with one fuel pump for each cylinder of the engine, which pump has a pump piston, driven by the engine in a reciprocating motion, that defines a pump work chamber to which fuel is delivered from a fuel tank and which communicates with a fuel injector valve that has an injection valve member by which at least one injection opening is controlled and which is movable in an opening direction counter to a closing force by the pressure generated in the pump work chambers.
Patent
Fuel-injection system for internal combustion engines
TL;DR: In this article, an electrically triggered control valve is provided, by which a communication of the line with a relief chamber is controlled, and by which the pressure prevailing in a control pressure chamber of the fuel injection valve is controlled.
Patent
Piezoelectrically actuated fuel injection valve
TL;DR: In this article, a valve for controlling liquids is provided with a liquid-filled coupling chamber, which is disposed between an actuator piston of a piezoelectric actuator and a piston that actuates a valve member.
Patent
Device for measuring the composition of fluids, in particular the components of exhaust gases from internal combustion engines
TL;DR: In this article, a light ray is used to irradiate the exhaust gas to be measured over the length of a measuring section and is weakened or changed more or less, depending on the content of constituents.
Patent
Vorrichtung zur Messung der Partikelbelastung im Rauch- oder Abgas eines Verbrennungsprozesses
TL;DR: In this article, a Meswertverfalschung durch Rusablagerungen in der Messtrecke auf den lichtdurchlassigen Korpern (29,30) verhindert und ein kontinuierlicher Betrieb der Mesvorrichtung sichergestellt.
