What engine is used in the BYD Yuan?
1 Answers
BYD Yuan uses a self-developed all-aluminum engine. The engine model of BYD Yuan is BYD473QE, with a maximum power of 80 kW, a maximum torque of 145 Nm, a maximum horsepower of 109 Ps, a maximum power speed of 5800 rpm, and a maximum torque speed of 4800 rpm. The engine of BYD Yuan can be maintained daily using the following methods: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected according to the additional devices of the intake and exhaust system and the use conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to the mechanical load, and the selection standard should not be lower than the requirements specified by the manufacturer; Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance will deteriorate, causing various problems to the engine. To avoid failures, the oil should be changed regularly according to the usage conditions, and the oil quantity should be moderate; When the oil passes through the fine holes of the filter, the solid particles and sticky substances in the oil accumulate in the filter. If the filter is blocked and the oil cannot pass through the filter element, the filter element will burst or the safety valve will open, allowing the oil to pass through the bypass valve, bringing the dirt back to the lubrication part, accelerating engine wear and increasing internal pollution; Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall, mixing with the metal powder generated by part wear to form sludge. When the amount is small, it is suspended in the oil; when the amount is large, it precipitates from the oil, blocking the filter and oil holes, making engine lubrication difficult and causing wear; Regularly use a radiator cleaner to clean the radiator. Removing rust and scale can not only ensure the normal operation of the engine but also extend the overall life of the radiator and the engine.
