車輛的日常維修及保養(yǎng)主要包括定期更換機油、檢查和更換濾清器、剎車系統(tǒng)、輪胎、冷卻系統(tǒng)、燃油系統(tǒng)和空氣濾清器、電氣系統(tǒng)、底盤和懸掛系統(tǒng)以及車身和外觀維護等。詳細介紹如下：

　　The daily maintenance and upkeep of vehicles mainly includes regular oil changes, inspection and replacement of filters, brake systems, tires, cooling systems, fuel and air filters, electrical systems, chassis and suspension systems, as well as body and exterior maintenance. The detailed introduction is as follows: 12

　　發(fā)動機機油和濾清器：定期更換機油和機油濾清器是保持發(fā)動機正常運轉的關鍵，機油起到潤滑、清潔和冷卻發(fā)動機內(nèi)部零件的作用，而機油濾清器則能過濾掉機油中的雜質(zhì)。

　　Engine oil and filter: Regularly changing the oil and oil filter is the key to maintaining normal engine operation. Oil plays a role in lubricating, cleaning, and cooling internal parts of the engine, while the oil filter can filter out impurities in the oil.

　　剎車系統(tǒng)：包括檢查剎車片、剎車盤、剎車液等，確保其處于良好狀態(tài)，并定期更換磨損的部件。

　　Brake system: including checking brake pads, brake discs, brake fluid, etc. to ensure they are in good condition, and regularly replacing worn components.

　　輪胎：定期檢查輪胎的磨損、并在必要時進行輪胎的旋轉和平衡，輪胎的狀況直接影響到車輛的行駛安全和性能。

　　Tires: Regularly check for tire wear and, if necessary, rotate and balance the tires. The condition of the tires directly affects the driving safety and performance of the vehicle.

　　冷卻系統(tǒng)：負責降低發(fā)動機溫度，防止過熱，應定期檢查冷卻液的水平和質(zhì)量，并清洗冷卻系統(tǒng)內(nèi)部的雜質(zhì)和沉積物。

　　Cooling system: responsible for reducing engine temperature, preventing overheating, regularly checking the level and quality of coolant, and cleaning impurities and deposits inside the cooling system.

　　燃油系統(tǒng)和空氣濾清器：定期更換燃油濾清器和空氣濾清器以及清洗噴油嘴等，可以保持燃油系統(tǒng)的良好狀態(tài)。

　　Fuel system and air filter: Regular replacement of fuel and air filters, as well as cleaning of fuel injectors, can maintain the good condition of the fuel system.

　　電氣系統(tǒng)：包括電池、發(fā)電機、點火系統(tǒng)等，應定期檢查其功能和狀態(tài)。

　　Electrical systems: including batteries, generators, ignition systems, etc., should be regularly checked for their functionality and status.

　　底盤和懸掛系統(tǒng)：負責車輛的支撐和行駛穩(wěn)定性，應定期檢查懸掛部件的磨損和緊固情況以及底盤的腐蝕和損傷。

　　Chassis and suspension system: responsible for the support and driving stability of the vehicle, and should regularly check the wear and fastening of suspension components, as well as the corrosion and damage to the chassis.

　　車身和外觀維護：包括清洗車輛、打蠟、修復劃痕等，這不僅能保持車輛的外觀美觀，還能防止車漆腐蝕和損傷。

　　Body and appearance maintenance: including cleaning the vehicle, waxing, repairing scratches, etc. This not only maintains the appearance of the vehicle, but also prevents paint corrosion and damage.

　　此外，根據(jù)車輛的具體情況和制造商的建議，還可能需要進行其他特定的維護保養(yǎng)項目，如變速箱油的更換等。以上就是車輛日常維護保養(yǎng)內(nèi)容的一些常見項目。

　　In addition, depending on the specific condition of the vehicle and the manufacturer's recommendations, other specific maintenance and upkeep items may be required, such as replacing the transmission oil. The above are some common items for daily maintenance and upkeep of vehicles.
