摘要： An ignition timing control device for an internal combustion engine includes a storage device and a processor. The storage device stores a first learned neural network and a second learned neural network. The processor is configured to perform, in a next cycle where ignition timing is delayed, control to delay the ignition timing in a cycle after the next cycle based on a difference between a predictive value of an estimate of a value representing knocking intensity calculated with use of the second learned neural network and the estimate of the value representing the knocking intensity calculated with use of the first learned neural network. When the difference is larger than a predetermined set value, the processor is configured not to perform the control to delay the ignition timing in the cycle after the next cycle.

摘要： There is provided an internal combustion engine ignition apparatus that can effectively raise the ignitability of an inflammable fuel-air mixture, by applying electric power corresponding to the combustion state of an internal combustion engine. A combustion state detection apparatus detects an combustion state inside a combustion chamber of the internal combustion engine; based on the combustion state detected by the combustion state detection apparatus in accordance with an operation state of an ignition coil apparatus, a current supply apparatus supplies an AC current to a spark discharge path formed in the gap of an ignition plug; then, a control apparatus controls the output of the current supply apparatus.

摘要： A system according to the principles of the present disclosure includes a first burn duration module and a spark control module. The first burn duration module determines a first duration of at least a portion of a fuel burn within a cylinder of an engine from a first time when a first predetermined percentage of a mass of fuel within the cylinder is burned to a second time when a second predetermined percentage of the fuel mass is burned. The spark control module controls a spark plug to adjust spark timing of the cylinder based on the first burn duration.

摘要： A valve is installed in an opening provided in a thin wall of an air intake pipe, which supplies combustion air from a flow control device to a cylinder of an internal combustion engine, to relieve excess pressure in the pipe. The valve includes a socket connected to a segment of the air intake pipe, and an elastomer, umbrella valve member is supported in the socket to normally cover the opening in the pipe and to undergo deformation when the pressure in the pipe reaches a predetermined value to uncover the opening and to connect the interior of the pipe to the ambient atmosphere.

摘要： The heat generating ratio for every crank angle is calculated as a combustion ratio for the total amount of heat generated by the engine, and the ignition timing is so corrected that the crank angle corresponding to from 10% to 90% of the combustion ratio becomes minimal or is so corrected that the combustion ratio at a predetermined crank angle becomes equal to or larger than a predetermined value. This makes it possible to so control the ignition timing that the engine produces a maximum torque.

摘要： Combustion in a gas turbine is controlled through use of flame spectroscopy in order to achieve low NO.sub.x emissions in the exhaust. By monitoring the combustion flame in the turbine to determine intensity of non-infrared spectral lines, and dynamically adjusting the fuel/air ratio of the fuel mixture such that this intensity remains below a predetermined level associated with a desired low level of NO.sub.x emissions, the engine produces significantly reduced NO.sub.x emissions in its exhaust but at a sufficiently high combustion flame temperature to avoid any undue risk of flame-out, thereby assuring stable, safe and reliable operation.

摘要： A vacuum advance regulator designed to control the suction force of the vacuum that is applied to the vacuum advancer. The suction, in turn, controls the spark timing and allows combustion to occur when the crank position is at 12 degrees at the ATDC, thus, producing maximum engine power efficiency. The regulator consists of a body (1) containing in part, a vacuum chamber (2) that is connected to the outside of the body by a pair of nipples (3) that are inserted through a first bore (4) and a second bore (4'). The other side of the nipples are connected to a vacuum hose (11). One side of this hose is connected to the vacuum advancer while the other side is connected to the carburetor. The vacuum advance regulator also includes a pair of parallel adjustable throttles (5) and (5') that are in-line with the vacuum chamber (2). The two adjustable throttles provide the adjustment means that allows the vacuum force to set the spark timing.

摘要： An apparatus for controlling the timing of ignition of an internal combustion engine. The apparatus includes a cylinder pressure sensor sensitive to combustion pressure in a cylinder for providing a signal indicative of a sensed cylinder combustion pressure, and a control circuit responsive to the cylinder combustion pressure indicative signal for controlling the engine ignition timing. The control circuit measures a crankshaft angle at which the cylinder combustion pressure is at maximum. The control circuit retards the ignition timing when the measured crankshaft angle is less than a first value and advances the ignition timing when the measured crankshaft angle is greater than a second value greater than the first value. The control circuit retails the ignition timing to interrupt the feedback control of the ignition timing when the measured crankshaft angle is in a range defined by the first and second values. This is effective to eliminate a tendency toward unstable engine operation resulting from the conventional manner in which the ignition timing is re-adjusted at more frequent intervals than is required.
