摘要： An engine ignition control method and system for controlling ignition timing that computes a predicted crankshaft angular velocity based on prior computed and verified crankshaft angular velocity and acceleration and determines a capture window of the next crankshaft position sensor pickup signal for the verification of the predicted crankshaft angular velocity. The ignition control system also utilizes both crankshaft position pickup signals and the intake manifold air pressure measurements for determining the stroke of the combustion cycle in turn providing more accurately timed signals for the fuel injection and ignition systems. During engine starts, the engine ignition control system performs a series of continuous spark-triggering, determines if each spark-triggering being at the correct or incorrect point in the combustion cycle by detecting if there is any engine acceleration and adjusts the generation of the signal for the next spark-triggering accordingly.

摘要： A two-stroke engine includes an ignition module that receives a detection signal from a magnetic sensor for detecting a permanent magnet and transmits an ignition signal to an ignition plug. The permanent magnet is provided at a single position on a flange that rotates synchronously with the magnetic sensor. The magnetic sensor is attached to one of sensor attachments and provided at two positions adjacent to the engine body. The sensor attachments and are so provided as to correspond to a rotational direction of the engine. With such an arrangement, the permanent magnet is less affected by noise because the permanent magnet is disposed at only one position. By changing a position at which the sensor is attached, the engine having common components is enabled to work in the same manner during both of normal rotation and reverse rotation.

摘要： An ignition timing circuit is disclosed which provides variable fuel ignition timing as a function of the rotational speed of a small internal combustion engine. A measure of the rotational speed of an engine is generated from the shape of pulses generated by a sensor. A timing delay circuit converts this measure of the rotational engine speed into a fuel ignition trigger signal with a controlled delay relative to the engine's angular position. This trigger signal activates a switching device which in turn delivers energy to the engine's spark plug system. A significant benefit of the disclosed ignition timing circuit is its ability to be enclosed in a package which is size and pin-compatible with standard silicon controlled rectifiers.
