Reasons: In winter, the temperature is lower, and the engine oil tends to become thicker, especially with low-quality oil, which can easily cause issues with engine operation. Introduction and Principle of a Four-Cylinder Engine: Also known as a four-cylinder engine, it is a machine capable of converting one form of energy into another more useful form. Typically, it converts chemical energy into mechanical energy. Sometimes, the term "engine" refers to both the power-generating device and the entire machine, including the power unit, such as gasoline engines or aircraft engines. The main component of the engine is the cylinder, which serves as the power source of the entire vehicle.
