This article first introduced the composition of the motorcycle igniter, followed by the introduction of the benefits of motorcycle DC igniter, and finally elaborated the difference between the motorcycle DC igniter and the AC igniter and how to determine the motorcycle igniter AC and DC, specific Follow Xiaobian to find out.
Motorcycle igniterThe motorcycle igniter is an auxiliary device to start the motorcycle engine, and the appearance is mostly under the black square shaped motorcycle seat. The common ignition start mode is divided into two types, ignition start mode and foot start mode. In terms of operation, the ignition start mode is more convenient and convenient than the traditional foot start mode.
The composition of motorcycle igniter is mainly composed of power supply, ignition coil, distributor, ignition switch, spark plug, additional resistor and its short circuit device, high and low voltage wires and so on.
1, power: consists of batteries and generators. When starting, the ignition system is provided by the battery to provide low-voltage energy; after the start, when the generator voltage is higher than the battery voltage, the ignition system provides low-voltage power by the generator.
2. Ignition Coil: The 12V low-voltage power provided by the car's power supply is converted into high-voltage electricity that can break through the spark plug electrode gap.
3. Distributor: Under the drive of the generator camshaft, the primary current of the ignition coil is turned on and off on time, so that the ignition coil generates high-voltage electricity in time, and high-voltage electricity is transmitted to each cylinder spark plug according to the ignition sequence; Artificially adjust the ignition timing. The function of the capacitor is to reduce the contact spark of the breaker and increase the secondary voltage of the ignition coil.
4. Ignition switch: Control the on/off of the low-voltage circuit of the ignition system and control the start and stop of the generator.
5, spark plug: The introduction of high-voltage electricity into the combustion chamber, resulting in spark ignition ignition mixture.
6. Additional resistor short-circuit device: Short-circuit the additional resistor when starting, increase the primary current of the ignition coil, and enhance the spark-over energy of the spark plug when starting.
(1) Easily replace low-voltage coils, which is simple and convenient to install; reduces engine noise and reduces engine vibration
(2) It is equipped with a secondary voltage regulator protector: that is, in the event of failure of the voltage regulator, the overvoltage of the impulse voltage can also work normally and have a long service life. (3) Fuel saving, economical and durable, 16.5% fuel economy per 100 kilometers. Principle of fuel economy: As we all know, the traditional igniters are all fired once (360°), so it is the number of revolutions of the engine and how many times the igniter is fired; and our factory's Yonghao Fuel Saving Dr. The design breaks through the traditional ignition basic principle, through the use of stepless frequency conversion technology to make the engine turn three times in two rounds of fire (240 °) to increase the number of ignition in the operating cycle of 33.3%, greatly reducing the combustion time of the gas in the cylinder As the combustion intensity is increased, the fuel-saving effect is naturally formed during use.
(4) Ultra-low temperature quick start, guaranteeing a successful start within minus 28°C, suitable for northern cold climate.
(5) Resistant to moisture: In the case of relatively large space humidity, it can also ensure normal work, applicable to the humid climate in the south.
(6) High-energy growth. First, the use of microelectronics frequency conversion technology, by increasing the ignition density and then increasing the combustion intensity of gasoline to fully burn the gas in the cylinder, the gas formed after the combustion has a strong explosion force, and promote the rapid increase in engine power, growth rate 20% to achieve the desired effect.
(7) Ultra-low pressure work. DC power supply above 2.8V can work normally.
(8) Fault self-test function. The internal design has a running fault self-test function. It is displayed by the running lamp.
1, appearance
The DC and AC igniters are basically the same in appearance and similar in appearance;
2, power supply
The AC igniter is powered by the magnet stator coil. The DC ignitor is powered by a battery or a rectifier. The power line through the igniter is from the magneto or the battery. It can be judged whether it is an AC igniter or a DC igniter;
3, flameout method
The AC igniter is a short-circuit flameout of the ignition signal line to the ground. The ignitor has a flameout line connected to the flameout switch. Turning off the flameout switch is a grounding short circuit flameout: while the DC igniter cuts off the DC power supply and shuts off the power by turning off the cutoff switch. Therefore, there is no flameout line on the DC igniter, so that the DC igniter is one line less than the AC igniter.
4, input voltage
AC igniter input voltage is generally 60 volts - 200 volts random machine speed changes, the volatility is relatively large; while the DC igniter is 12V battery power supply, voltage stability, so the DC ignition igniter minimum ignition speed than the AC igniter Low and more, generally about 1000r/min will be able to ignite, so the DC igniter cold start effect is better, as the heat engine starts, the two effects are similar.
5, ignition voltage
The ignition voltage of the AC igniter output to the ignition coil fluctuates between 70 volts and 200 volts with the change of the engine speed, and the spark energy fluctuates between 10,000 volts and 28,000 volts after boosted by the high voltage package. The ignition voltage of the igniter is stable at 230-240 volts, and the spark energy is stabilized at about 40,000 volts after being boosted by the high-voltage package. It will not change with the change of the engine speed. Therefore, the DC igniter is more efficient than the ignition energy of the AC igniter. Strong, faster performance.
6, fuel-saving performance
The ignition energy of DC igniter is higher than that of AC igniter, and the speed increase performance is far more than that of AC igniter, so the DC igniter is more fuel-efficient.
In summary, although there are many AC igniters on the market today, AC igniters have a certain advantage in terms of price, but the relative performance of DC igniters is stable, which can improve the overall performance of motorcycles. Oil, so with the progress of the times, AC and DC are inevitable trends.
The first is the visual measurement method
According to the engine magneto outlet to determine that there are more than two lines into the igniter plug, it is certainly the exchange, because the trigger line up to two, one more, it is certainly the AC line;
If there are only two incoming plugs, then AC and DC are not easy to say because some cars trigger the negative pole to be grounded. Only the positive pole is triggered to enter the igniter plug, but if it is a Honda tandem car, you can check whether there are bars inside the two-wire plug. The black and red lines are used to assist judgment, and in some cases, they are usually AC buses.
The above is only a basic judgment method. If some vehicles have auxiliary electronic devices, there may be multiple lines to enter the igniter plug. Special models are not discussed.
The second is the instrument method
Put the multimeter on DC 20V, open the motorcycle electric door lock, and the black test leads are grounded. The red test leads are in turn in contact with the igniter pins. If there is a 12V voltage, it is a DC car. If not, it is an AC car.
