How Many Cylinders Does the BMW 1 Series Engine Have?

[McGabriela]

The 1.5T engine in the BMW 1 Series is a three-cylinder engine with the model number B38A15C, delivering a maximum power of 103kW and a maximum torque of 220Nm. The 2.0T engine is a four-cylinder engine with the model number B48A20C, providing a maximum power of 141kW and a maximum torque of 280Nm. The BMW 1 Series engines are produced at the Liaoning Tiesi Engine Plant and are classified as domestically manufactured engines. For daily maintenance of the BMW 1 Series engine, the following methods can be employed: Use lubricating oil of the 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 specified requirements. Regularly change the engine oil and oil filter. The quality of any grade of lubricating oil will deteriorate during use. After a certain mileage, its performance will degrade, leading to various engine issues. To prevent malfunctions, change the oil periodically 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 accumulate in the filter. If the filter becomes clogged and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, 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. In small amounts, it remains suspended in the oil; in large amounts, it precipitates, 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.
