What engine does the Vios have?
2 Answers
The Vios engine is a domestically produced engine, manufactured by Tianjin FAW Toyota Engine Co., Ltd. The engine model of the Vios is 5NR-FE, with a maximum power of 82KW, a maximum torque of 139Nm, and a maximum horsepower of 112. Here are some daily maintenance methods for the Vios engine: Use lubricating oil of the 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, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will deteriorate during use. After a certain mileage, performance degradation can cause 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, it may rupture the filter or open the safety valve, allowing dirty oil to bypass the filter and return to the lubrication system, 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. These mix 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 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.
I drove my friend's 2021 Vios, which is equipped with a 1.5L naturally aspirated engine, model 5NR-FE. This engine delivers 113 horsepower and 138 Nm of torque, which is more than sufficient for city commuting. What surprised me the most was the fuel consumption, with an actual test result of 5.8 liters per 100 kilometers, and a full tank can last over 600 kilometers. Toyota engines are particularly durable; my friend has only changed the engine oil in five years of driving. The engine sound is very quiet at startup, but the noise becomes noticeably louder when the RPM exceeds 3000 on the highway. It is recommended to use 95-octane gasoline to significantly reduce carbon buildup.
