Patent DE-19733355-A1 (DE)
Title: Internal combustion engine state determination device
Inventor: TAKAHASHI YASUHIRO
IPC: F02D45/00
Filed: 1997-08-01
Abstract: The device comprises an ignition coil (2), a spark plug (4) connected to the high voltage end of the secondary of the coil, and an ion current detection circuit which includes a voltage bias that is connected to the low voltage end of the secondary winding of the coil and which detects an ion current which flows after the combustion of the air/fuel mixture from the bias via the plug. A current-limiter is inserted between the low voltage end of the coil and earth; and an electronic control unit (20) which determines the combustion state at a plug in agreement with the ion current. The bias applies a bias voltage to the plug via the low voltage end of the secondary with a polarity opposite to the high voltage for ignition. The current-limiter limits the current that flows from the bias to the plug via the secondary winding, whereby the voltage that develops at the high voltage end of the secondary from the time of the start of current supply to the primary is limited.

Title: Exhaust gas recirculation (EGR) control method esp. for diesel engines
Inventor: HEINITZ DIRK
IPC: F02D21/08
Filed: 1997-09-29
Abstract: A method for controlling the exhaust gas recirculation (EGR) in an internal combustion (IC) engine, in which, depending on the magnitude of the load and further input variables, in particular the IC engine revs, a desired value for the EGR-rate for the steady-state operation of the IC engine is ascertained, and an adjustment signal for controlling an EGR valve is derived from the desired value of the EGR-rate.  In an non-steady-state operating condition, the desired value of the EGR-rate is varied with a correction value (EGR-DIFF), which is generated in a correction element (5) in the non-steady-state operating condition of the IC engine.
