A method of measuring the quantity of air sucked into the combustion chamber of an i.c. engine contains a device in the induction system measuring flow into that system. The change in the air mass in a defined vol. between the measurement device and the combustion chamber is measured during...
An ion current in the combustion chamber of an internal combustion engine is measured by using the spark plug as an ion current sensor. The ignition circuit arrangement has an ignition coil or transformer with a primary winding forming a primary circuit and a secondary winding forming a secondary...
The invention relates to a pressure measuring device for a combustion chamber pressure sensor for an internal combustion engine. The pressure measuring device comprises a retaining part (12) which has a support surface (16) for a signal processing unit, a glow plug busbar (32), sensor element...
A thin 20m long pipe (16) is inserted through a plenum (13) into the combustion chamber (15). A pressure recorder (18) is connected to the pipe. To avoid false measurements caused by pressure waves reflected from temperature steps, either different pipe diameters (D1,D2,D3) are used ...
A circuit arrangement measures an ion current generated in the combustion chamber of an internal combustion engine during an iron current flow phase following an ignition phase. A voltage drop across a feedback resistor (R.sub.1) connected in parallel to an inverting amplifier is measured since ...
