摘要： The invention relates to a measuring circuit for sensing ionisation within a combustion chamber of an engine. The measuring circuit is arranged in the grounded end of the secondary winding (5) of an ignition coil (2), and includes a voltage source for measurements having a substantially constant potential. The voltage source for measurements used is a capacitor (13) which is charged by the spark current (SC), and subsequently after the ignition spark goes out will apply a bias voltage over the spark plug gap (3) with a reversed polarity in relation to the spark voltage. The ionisation within the combustion chamber is detected with a measuring resistance (14) arranged in series with the capacitor (13). A rectifying element (11) is connected in parallel with the measuring resistance, which will secure that the spark current is developed in the spark plug gap (4) and that the measurement current is passing through the measuring resistance (14). In accordance with the invention is the rectifying element grounded with a separated ground strap which do not pass the ground plane of the measuring resistance. The interference inducing spark current could then be conducted in a separated circuit without having to pass the ground plane used for the remaining electronic components of the circuitry.

摘要： The invention relates to an arrangement and a method for configuration of a combustion engine (10) control system. Said control system including a distributed computer network having a main computer ECU and a number of node computers CCU 1/CCU 2/CCU 3. Each node computer being arranged closely to a selected group of cylinders (11, 12/13, 14/15, 16) of the combustion engine and controlling at least fuel supply means (22) of each respective group of cylinders. The main computer and the node computers are connected to a common communication loop (1) transmitting control data from the main computer to the node computers and information from the node computers to the main computer. By using dual switch means (30, 31-32/51a-b, 52a-b, 53a-b) at each node computer, could the main computer as well as each individual node computer be configured for the present engine type, and the node computers also for the specific cylinders. The switch means preferably constitutes a number of rotary switches of the BCD-type. A simple and logical configuration could thus be obtained rapidly without needing any sophisticated tools. In an alternative embodiment is a permanent configuration obtained by using code contacts (51b, 52b, 53b) included in a part (54) of the node computer housing permanently attached to the engine, with the node computer being integrated in a lid (50) of the node computer housing. When the lid (50) is mounted on top of the bottom part (54) of the node computer housing, then the setting of the code contacts are transmitted to the node computer. The main computer is prevented from starting the engine if configuration is incorrect.
