An improved method applied in combustion engines which use the ionization current in the combustion chamber in order to extract a parameter representative of the pressure in the cylinder, which parameter is used for controlling the ignition timing within an extended range for the load-
A method and system for adaptive correction of the amount of fuel supplied in two-stroke combustion engines which during a continuous operation period regulates the air-fuel mixture regulated by increments in the lean direction (.DELTA.F.sup.-) or in the rich direction (.DELTA.F.sup.+),
An arrangement and method for regulation of idle speed and charge pressure in a supercharged combustion engine (1) which engine includes an idle speed valve (20) arranged in a shunt channel (21) by-passing the throttle (9) and a gate valve (10) regulated by a pressure controlled diaphrag
The invention relates to a method for achieving elevated charging of an ignition capacitor in a capacitive type ignition system for internal combustion engines. When starting a cold engine or when starting the engine under other conditions in which the battery capacity is low, activa
The invention relates to a method for detecting ion current in an ignition circuit included in the ignition system of an internal combustion engine, where a measuring voltage is applied to the ignition circuit and a measuring device is utilized for detecting ion current possibly present
