What engine does the BYD Yuan have?
2 Answers
The engine of the BYD Yuan is independently developed and produced by BYD Auto, belonging to a domestically manufactured engine. The 1.5L version of the BYD Yuan is equipped with the BYD473QE engine, delivering a maximum torque of 145 Nm and a maximum horsepower of 109. The 1.5T version features the BYD476ZQA engine, with a maximum torque of 240 Nm and a maximum horsepower of 154. For daily maintenance of the BYD Yuan engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's requirements; Regularly change the oil and oil filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance deteriorates, causing various problems for the engine. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level; When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication area, accelerating engine wear and increasing internal contamination; 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; Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.
BYD's Yuan series, such as the Yuan Pro and Yuan PLUS, are all pure electric vehicles, so they don't have traditional internal combustion engines but instead use efficient electric motors. I've driven the Yuan PLUS myself, and the driving experience is smooth with seamless acceleration—it goes from 0 to 100 km/h in just a few seconds, making overtaking effortless. Daily charging is also convenient; a home charging station can fully charge it overnight, providing around 400 km of range, which is more than enough for city commuting. BYD's Blade Battery technology is quite reliable—safe and energy-efficient, unlike gasoline cars that require regular maintenance. Personally, I think the quietness of electric vehicles is outstanding; there's almost no noise while driving, making it stress-free even in rain or traffic jams. I recommend opting for the smart system, which displays charging points on the navigation, making long trips easier to plan. After driving it for over a year, I've never had any issues, and the maintenance costs are low—just tire and brake checks are enough.
