摘要： An ignition control device controls the alternate grounding of magnetos, or other ignition systems, in internal combustion engines utilizing two spark plugs per cylinder. The ignition control device can include two separate ignition systems to control each magneto. The ignition control device can alternate arcing of opposing spark plugs for each combustion cycle of the internal combustion engine.

摘要： Disclosed is an ignition drive module with stable performance and reliable function, which comprises a module signal input end, a voltage input end, a module signal output end, a comparator connected to the module signal input end a maximum dwell timer module connected to the comparator, a logical judgment module connected to the comparator, and an insulated gate bipolar transistor connected to the logical judgment module. The logical judgment module receives signals from the maximum dwell timer module and the comparator to determine whether to activate the insulated gate bipolar transistor. The output end of the insulated gate bipolar transistor is connected to the module signal output end.

摘要： An ignition circuit and a method of operating an igniter (preferably a traveling spark igniter) in an internal combustion engine, including a high pressure engine. A high voltage is applied to electrodes of the igniter, sufficient to cause breakdown to occur between the electrodes, resulting in a high current electrical discharge in the igniter, over a surface of an isolator between the electrodes, and formation of a plasma kernel in a fuel-air mixture adjacent said surface. Following breakdown, a sequence of one or more lower voltage and lower current pulses is applied to said electrodes, with a low “simmer” current being sustained through the plasma between pulses, preventing total plasma recombination and allowing the plasma kernel to move toward a free end of the electrodes with each pulse.

摘要： The subject matter of this specification can be embodied in, among other things, a method that includes receiving a collection of measurements of electric current amplitude in a primary winding of an engine ignition system having the primary winding and a spark plug, identifying an ignition start time, identifying an inflection point based on the plurality of measurements, determining an inflection point time representative of a time at which the identified inflection point occurred, determining a spark start time based on an amount of time between the ignition start time and the inflection point time, and providing a signal indicative of the spark start time.

摘要： In at least some implementations, an auxiliary power supply in an ignition system for a light-duty combustion engine includes a first auxiliary winding and a second auxiliary winding coupled in parallel with the first auxiliary winding such that both windings are arranged to provide power to an auxiliary load. The first auxiliary winding may include a greater number of turns than the second auxiliary winding. A ratio of the number of turns in the first auxiliary winding to the number of turns in the second auxiliary winding may be between 1.5:1 and 10:1, the first auxiliary coil and the second auxiliary coil may have between 50 and 2,000 turns, and the first auxiliary coil and the second auxiliary coil are formed from wire between 25 and 45 gauge.

摘要： An internal combustion engine for an aircraft can include a crankshaft configured to drive a propeller; a camshaft coupled to the crankshaft; and an ignition controller coupled to the camshaft and including a visual indicator, the visual indicator configured to produce a visual signal at a predetermined angular position of the engine. An ignition controller for an internal combustion engine can include a housing and a P-lead connection extending from the housing, the ignition controller configured to selectively supply or cut main electrical power from the engine via the P-lead connection, the ignition controller also configured to selectively supply its own power.

摘要： In an ignition control apparatus, a control unit controls switching elements so as to supply a primary current to the other end side of a primary winding opposite to one end thereof connected to a DC power source by discharging (which is performed by turning on a second switching element stored energy from a capacitor during ignition discharge (which is started by turning off a first switching element. In particular, the control unit controls the second switching element or the third switching element so as to provide variability to the amount of stored energy discharged from the capacitor according to an operating state of an internal combustion engine.

摘要： The present invention relates to a gas heat pump and a control method therefor and, according to the present invention, the method for controlling a gas heat pump, which comprises an ignition plug and a gas engine having an engine combustion unit including a plurality of combustion spaces, may include: a target setting step of setting a target ignition energy amount on the basis of a refrigerant load amount determined according to a driving condition of the gas heat pump; an ignition step of igniting fuel injected into the combustion spaces; a comparison step of comparing an output energy amount emitted in the ignition step with a target ignition energy amount set in the target setting step; and a step of changing an energy amount required to ignite the fuel when the output energy amount and the target ignition energy amount do not coincide in the comparison step.
