摘要： A novel process and system for computing and adjusting the optimum ignition advance in an internal combustion engine wherein knocking is detected by means of an accelerometer rigidly fastened to the cylinder head of the engine. An output from the accelerometer is integrated, converted into digital form, and processed by processing circuits to derive an average value C proportional to n preceding knocks and two comparison thresholds S.sub.1 and S.sub.2, each a linear function of the preceding average value C. The accelerometer output integrated and converted into digital form is compared with each of these thresholds and the existence of a preknocking or audible knocking value is deduced and then used to act on the programmed electronic ignition advance.

摘要： An electrical protection apparatus is disclosed, including a circuit breaker and an effector. The circuit breaker includes a first switch circuit including stationary and movable contacts, provided between input and output terminals. The effector includes a second switch circuit that is provided in series with the first switch circuit. Further, the circuit breaker includes an actuating mechanism for opening the contacts, electromagnetic and thermal trip devices for controlling the actuating mechanism, and first and second guiding horns spaced apart from each other and defining therebetween an arc extinguishing chamber. The first arc guiding horn is electrically connected with the movable contact to the input terminal, while the second arc guiding horn includes a switching electrode extending therefrom, the switching electrode being spaced apart from the stationery contact via an insulating gap. Upon forming an arc between the stationery and movable contacts by tripping of the apparatus, the arc switches to the switching electrode, thereby shunting the effector.

摘要： A process whereby fuel injection is interrupted in response to detection of a deceleration and injection is again ordered when a threshold linked to the engine speed is reached. The engine speed (N) or period of rotation (T) is measured from consecutive equal intervals or angles of rotation. A difference (.DELTA.T, .DELTA.N) is then computed between the value of the last measured speed or period and the value seen through a high-pass filter of the speed or period measured at the preceding interval. This difference (.DELTA.T, .DELTA.N) is compared with a fixed threshold (S) and if an engine deceleration condition is detected, fuel injection is again ordered when the difference (.DELTA.T, .DELTA.N) is greater than the threshold (S).
