汽車是現代人生活中不可或缺的交通工具，而汽車的運作與安全性取決於各種不同的零件與系統。其中，引擎是汽車的心臟，提供動力與能源；車軸支持著汽車的重量，使其能夠順利運行；懸吊系統讓汽車在不平坦的路面上更穩定；制動系統提供了緊急停車的功能，確保行車安全；而過濾器則保護引擎不受雜質影響。
除了引擎、車軸、懸吊、制動、過濾器這些關鍵元件外，還有許多其他重要的汽車零件與系統。例如點火系統協助汽車引擎點燃燃油；傳動系統將引擎動力傳遞到車輪；冷卻系統保持引擎運轉溫度在適宜範圍；電氣系統控制著各種汽車功能；燃油系統供應引擎所需的燃料；排氣系統排出引擎燃燒後的廢氣；而電子控制單元則控制著整個汽車的運作。
此外，輪胎、照明系統、車身零件、真空泵、氣囊、油封、傳感器等零件也都扮演著非常重要的角色。這些零件與系統的良好運作與維護，關係著汽車的性能、安全性和壽命。
在汽車維修保養過程中，應該定期檢查各項零件與系統的狀況，及時更換老化或損壞的零件，以確保汽車的安全性和可靠性。只有對汽車的各個部分都有充分的了解和重視，才能有效地保護自己與他人的行車安全。

Title: The Importance and Function of Car Parts
Article: Cars are an indispensable mode of transportation in modern life, and their operation and safety depend on a variety of different parts and systems. Among them, the engine is the heart of the car, providing power and energy; the axle supports the weight of the car, allowing it to move smoothly; the suspension system makes the car more stable on uneven roads; the braking system provides emergency stopping functions to ensure driving safety; and the filter protects the engine from impurities.
In addition to key components such as the engine, axle, suspension, brakes, and filters, there are many other important car parts and systems. For example, the ignition system assists the engine in igniting fuel; the transmission system transfers engine power to the wheels; the cooling system keeps the engine operating at the appropriate temperature; the electrical system controls various car functions; the fuel system supplies the fuel needed for the engine; the exhaust system removes exhaust gases from the engine combustion; and the electronic control unit controls the operation of the entire car.
Additionally, parts such as tires, lighting systems, body parts, vacuum pumps, airbags, seals, sensors, etc., all play important roles. The proper operation and maintenance of these parts and systems are related to the performance, safety, and lifespan of the car.
During the maintenance of cars, it is important to regularly check the condition of various parts and systems, replace aging or damaged parts promptly, to ensure the safety and reliability of the car. Only with a comprehensive understanding and emphasis on all parts of the car can driving safety for oneself and others be effectively protected.
