Title: Process for adding a reductant to an internal combustion engine exhaust gas containing nitrogen oxides uses a correction factor of the change of catalyst charge either from a performance graph or from sensors
Inventor: DOERING ANDREAS
IPC: F01N3/20
Filed: 1999-02-17
Abstract: For the intermittent operation a correction is carried out over the change of the catalyst charge, e.g. determined from the injection amount, gas pedal adjustment or manifold pressure change and/or from exhaust gas temperature changes and/or from NOx concentration changes, either from a performance graph or from sensors.  Process for adding a reductant to an internal combustion engine exhaust gas containing nitrogen oxides spatially to the exhaust gas line before a catalyst system comprises drawing up engine-specific values for the NOx concentration and exhaust gas amount determined in connection with a reference internal combustion engine and the temperature of the exhaust gas sensed during engine operation, and calculating a reductant rate using these parameters. This reductant rate is subjected to a (high) dynamic correction depending on load changes on the engine and a corresponding reductant amount is fed to the exhaust gas stream. For the intermittent operation a correction is carried out over the change of the catalyst charge, e.g. determined from the injection amount, gas pedal adjustment or manifold pressure change and/or from exhaust gas temperature changes and/or from NOx concentration changes, either from a performance graph or from sensors.

Title: Releasing energy using controlled nuclear fusion involves use of plasma chamber having plasma which operates with specific energy
IPC: H05H1/12
Filed: 1999-06-02
Abstract: In the process, the plasma chamber posses plasma during operation of the resonance line width within the frequency comb corresponding to self resonance frequency, so that the average relative energy between electrons and ions is large.   The Coulomb collision probability is reduced so that the loss of electrons from the magnetic containment is controlled.  Any electrons still escaping are reflected back into the magnetic containment by electric fields. The resonance loss that occurs in electron-cyclotron resonance heating of electrons to considerable  energies is compensated with frequency comb.  The resonance requirement is satisfied in one place, up to a maximum energy Emax.
