摘要： A timing circuit for stabilizing idling of an internal combustion engine, particularly marine racing applications where idle speed must be reduced to enable gear engagement, notwithstanding the use of a racing cam otherwise requiring higher idling speed. Delay means (8) provides a radical reduction in spark timing along a negative slope (16) relative to a baseline curve (6) up to a predetermined speed such as 900 rpm at which there is maximum relative timing delay (18). A speed increases in this range, there is more retard because of the negative slope, which further retarded timing slows engine speed, hence providing self-stabilization. As engine speed decreases in such range, there is less retard, and the advanced timing increases engine speed, again providing self-stabilization. At engine speed increases above the predetermined speed such as 900 rpm, there is a rapid advance in timing along a steeper positive slope (20) to merge with the baseline curve (6). Cranking and warm-up control circuitry (12) and acceleration detection circuitry (14) are also provided for eliminating or reducing the relative timing delay under conditions where maximum spark advance is desired.

摘要： The invention concerns a process for controlling engine knock in an internal-combustion engine, in which, when a cylinder knocks, the ignition point is retarded and subsequently reset to the original value. With turbocharged engines, it is proposed that, when a limiting ignition-point value ( alpha lim) dependent on the engine exhaust temperature (Tex) is reached, the charge pressure (P) is reduced, and that the charge pressure (P) is increased again as soon as the limiting ignition-point value ( alpha lim) is reached again as a result of the ignition-point ( alpha ) being retarded. Depending on the operating conditions of the engine at any time, the ignition-point and charge pressure values ( alpha , P) selected are stored to give an adaptive process, being taken as initial values when the same operating conditions occur again.

摘要： A device in which knock information of an engine is detected by a knock sensor, knock signal components are selectively produced from the knock information through a frequency filter, a reference voltage of knock detection is made from the above output, and knocking generated in the engine is detected by comparing the reference voltage with the output of the frequency filter. A plurality of the above knock detection systems are provided, where the knock sensors, frequency filters and the circuits for producing reference voltages are designed to have characteristics that are different depending upon the individual detection systems. Therefore, optimum characteristics can be obtained in each of the knock detection systems; i.e., the knock detection systems exhibit characteristics to uniformly and reliably detect knocks of all cylinders of an engine.

摘要： This invention is characterized in that, in order to use an engine like a nut runner by shifting between a forward rotational mode and a reverse rotational mode, rotation positions taken by a crankshaft when a primary current has a maximum voltage during forward and reverse rotations of the engine are set symmetric with respect to and ahead of a rotation position of the crankshaft corresponding to the upper dead point of a piston. When the voltage of the primary current in an electromotive coil (97) becomes maximal in a predetermined rotation position, which is ahead of the upper dead point of the piston (7) with respect to the rotational direction of the crankshaft, while the engine is rotated forwardly or the engine is rotated reversely, this voltage is detected by an ignition unit (177) in a position, in which the voltage reaches a predetermined level in the vicinity of the maximum level, or in a position, in which the voltage drops from the maximum level by a predetermined voltage, so that the primary current is short-circuited to generate a high voltage current in a secondary circuit and perform electric discharge at an ignition plug (45). Since the time of this ignition is set in the same position, which is ahead of the upper dead point, whether the engine is rotated forwardly or the engine is rotated reversely, it is unnecessary to regulate an ignition time according to the directions of the rotation.

摘要： Manual switching of the carburettor enables a change-over from a characteristic mixture for lambda = 1 (three-way catalyst and lambda probe) with unleaded fuel, to a characteristic field of the mixture for lambda = &cir& / 1. Furthermore, manual switching or a choice of two characteristic fields among four for the ignition angle is possible by means of switching contacts (4, 10, 11), i.e. for premium leaded fuel (sb) and regular leaded fuel (nb). A second automatic switch (14) makes it possible to obtain, depending on a threshold value (18) of an engine operating parameter, automatic switching between the characteristic fields of the ignition angle for su and nu as well as those for sb and nb. Preferably a threshold value is derived from a knock adjustment, said value indicating the knocking frequency or intensity.
