Wuling Rongguang B12 engine alternator belt model is 4PK850, where PK represents the tooth pitch=3.5mm, 4 indicates the belt has 4 wedge teeth, and 850 means the effective belt length is 850mm. Engine principle is explained below: 1. Explanation 1: The operating resistance of a car alternator relates to the rotor's excitation voltage and current. Greater excitation current results in higher power generation, correspondingly increasing the alternator's operating resistance. For common AC or DC alternators, when there's no output current, the winding essentially behaves like an iron block with bearings. 2. Explanation 2: Besides bearing friction, there's no other resistance. When the output is loaded, the rotor generates strong magnetic fields that interact with the stator coil poles, creating attraction. Greater magnetic field intensity leads to higher operating resistance, and heavier loads increase magnetic flux cutting resistance, meaning greater operational resistance.

What brand is the engine of the Geely Boyue?

The engine of the Geely Boyue is produced by Geely Auto itself, utilizing technology from Volvo, making it a domestically manufactured engine. The engine model of the Geely Boyue is JLE-4G18TDC, a 1.8T version with a maximum power of 135kw/5500rpm and a maximum torque of 285Nm/1500-4000rpm. The 2.0L version has a maximum power of 104kw/6000rpm and a maximum torque of 178Nm/4000-4500rpm. For daily maintenance of the Geely Boyue's engine, the following methods can be applied: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, ensuring the standard meets or exceeds the manufacturer's requirements. Regularly change the oil and filter. The quality of any lubricating oil will degrade over use. After a certain mileage, performance deteriorates, leading to various engine issues. To prevent malfunctions, change the oil periodically based on usage conditions and maintain an appropriate oil level. As oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter or open the safety valve, allowing oil to bypass and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Periodically use a radiator cleaner to flush the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.
