Title: Combustion engine with direct fuel injection to cylinder
Inventor: FRAIDL GUENTER DR DIPL ING
IPC: F02D41/02
Filed: 1998-06-20
Abstract: The engine intake system and combustion chamber are arranged to form a layer of charge in the cylinder. It has a unit to switch between a stratified lean operation and a stratified stoichiometric operation according to the necessary quality of exhaust emissions. The unit is switched to stratified stoichiometric operation during driving through centres of population and in open country it is switched to a lean mixture operation.

The switching unit has a sensor to sense external signals indicating if it is to switch to a stoichiometric operation or not.
Patent DE-19830735-A1 (DE)
Inventor: SCHUNK NIKOLAUS
IPC: H04B10/27
Filed: 1998-07-09
Abstract: A wavelength router for optical bidirectional transmission of data, containing a plurality of add/drop filters (1) for signal injection to form a wavelength multiplex and for selective extraction of signals in order to break said multiplex down. A wavelength router of this kind represents a considerable amount of complexity in terms of circuitry; especially since only one respective signal of a subscriber can be injected or extracted using an add/drop filter. The aim of the invention is to reduce overall circuit complexity in said wavelength router. Injection and extraction are carried out respectively in the same add/drop filter (1) for a subscriber. In order to avoid crosstalk, extraction occurs at a wavelength of lambda i and injection occurs at a down-shifted wavelength  lambda i-1. Preferably, the wavelength difference between injection and extraction corresponds to a wavelength distance of the wavelength multiplex.
