What are the functions of the five wires of the motorcycle generator?
There are two cooling methods for diesel generator sets: air cooling and water cooling.
1. Air cooling
The air cooling method uses air as the cooling medium to transfer the heat from the heated parts of the diesel engine. This cooling method consists of Composed of cooling fan and guide cover.
In order to increase the heat dissipation neps, many corrugated fins are usually cast on the outer walls of the cylinder block, cylinder head and each radiator. When working, the fan rotates to flow the air along the air guide hood to the surface of the cylinder block and cylinder head. When the cold air flows through the heat sink, it takes away the heat given by the cylinder block and cylinder head.
2. Water cooling
The water cooling method uses water as the cooling medium to transfer the heat from the heated parts of the diesel engine. The characteristic of this cooling method is that it is easy to adjust the cooling intensity when the temperature or workload changes.
There are two types of water cooling methods: open type and closed type. In an open cooling system, the circulating water is directly connected to the atmosphere, and the steam pressure in the cooling system is always maintained at atmospheric pressure. In a closed system, water circulates in the closed system, and the vapor pressure of the cooling system is greater than the atmospheric pressure. Since the temperature difference between the cooling water temperature and the outside air temperature increases, the heat dissipation capacity of the entire cooling system is improved.
1. The green wire is the ground wire, just the ground wire in the wiring harness (also green).
2. Blue (usually blue/white or blue/yellow) is the trigger coil wire, which is connected to the igniter.
3. Yellow and white are lighting charging coil wires, which are connected to the same color wires of the rectifier.
4. Red (usually black/red or white/red) is the magneto ignition coil wire, which is connected to the igniter to provide ignition power to the igniter.
The green and ** two are not connected, it is to change the DC, this has no effect.
Extended information
Motorcycle electrical wiring:
The electrical wiring of motorcycles is basically similar to that of cars. Electrical circuits are divided into power supply, ignition, lighting, instrumentation and audio parts.
The power supply part is generally composed of an alternator (or powered by a magneto charging coil), a rectifier, and a battery. Magnetos for motorcycles also have various structures depending on the model of the motorcycle. Generally, there are two forms: flywheel magneto and magnet rotor magneto.
Flywheel magnetos are generally used on small-displacement micro and light motorcycles. Inside the flywheel, four magnets are evenly distributed, rotating with the engine crankshaft, and the stator frame is fixed on the crankshaft. On the box, there are magneto coils, lighting coils, and breaker assemblies fixed on it. When the flywheel rotates, the magnetic field lines alternately pass through each coil, causing the coils to generate induced alternating current.
In the magnet rotor type magneto, its structure is opposite to the above. Six magnets are evenly distributed on the circumference of the rotor. The magnets and the rotor are die-cast together with aluminum alloy, and the rotor is keyed to the crankshaft. connect. There are six sets of coils wrapped around an iron core distributed within the stator. When the rotor rotates in the stator, the magnetic field lines alternately pass through the stator coil, causing it to induce alternating current.
There are three types of ignition methods for motorcycles: battery ignition system, magneto ignition system and transistor ignition system. In the ignition system, there are two types: contact capacitor discharge ignition and non-contact capacitor discharge ignition. The English abbreviation of contactless capacitive discharge is C.D.I. C.D.I actually refers to a combined circuit composed of a capacitor charging and discharging circuit and a thyristor switching circuit, commonly known as an electronic ignition.
There are wires of various colors distributed in the motorcycle circuit. It is customary to use the red wire as the power "+" wire, the black wire as the "-" wire, the orange wire as the wire leading to the ignition coil, and the magnetic wire. The motor output current is the white wire, the blue wire is the headlight wire, etc. This is just a general usage for reference.
