The motorcycle engine ignition theory
According to the Central Plains Yoshio Japanese scholars propose the theory of ignition, Moped Motorcycles Moped Motorcycles spark plug electrodes discharge through the ignition, after ignition, the mixture can form in the fire, outbreak of fire can burn two different concepts. Spark plug ignition system produces spark decided by the outbreak of combustion in addition to the ignition system, but also with the fuel properties, mixture concentration, cylinder pressure, cylinder temperature, cylinder gas flow rate and other factors.
Spark plug in cylinder temperature, pressure and gas mixture surrounding the formation of sparks, in addition to take some high voltage and ignition energy, but also by the duration of the spark ignition system and release mode and effect. In general, laboratory testing of motorcycle spark duration 200ms, while in fact spark duration than the 200ms required 2 to 3 times larger.
Discharge spark plug for ATV Quad academic theory has been debated, high temperature thermal process claims under the theory of combustion of the oil molecules; chemical process theory claims spark activation energy of fuel molecules burning; ionized gas molecules on the ideas generated by the impact ionization avalanche of reaction, spark discharge; Central Yoshio that spark discharge is divided into two processes, namely, capacitor discharge and the discharge inductor, Special Vehicles capacitor discharge the high voltage coil to produce spark discharge between the electrodes.
The high voltage coil primary circuit as a large distributed capacitor, capacitor discharge from the beginning, a sharp decline in the coil primary voltage, then the secondary side of the Cub Motorcycle coil induces a high voltage spark discharge to a phenomenon known as inductive discharge . Inductive discharge waveform, t1 ~ t2 to boost the process, t2 ~ t3 of capacitor discharge process, t3 ~ t4 in the inductor discharge process, the measured capacitance and inductance of the discharge data shown in Table 1.
