What is the upper guard plate of a car engine
The engine guard plate of a car is a protective device installed at the bottom of the engine. It is mainly used to protect core components such as the oil pan and transmission from the impact of stones and potholes on the road surface, and at the same time prevent soil from covering the engine and affecting heat dissipation.
Material type
Youdaoplaceholder0 plastic/resin guard plate : light in weight and low in price, suitable for daily urban commuting, but prone to damage and cannot be repaired.
Youdaoplaceholder0 Metal guard plate (steel/aluminum alloy) : It has strong impact resistance and is suitable for off-road or complex terrains, but it is heavy and may cause abnormal noise.
Youdaoplaceholder0 plastic-steel alloy guard plate : Made of modified high-molecular polymer material, it combines lightweight and corrosion resistance, and will not prevent the engine from sinking when impacted.
Whether installation is required
Youdaoplaceholder0 Original factory guard plates are sufficient for daily commuting : Most new cars are equipped with resin or thin steel plate guard plates from the factory, which can meet the protection needs of urban roads.
Youdaoplaceholder0 For off-road or extreme road conditions, metal guard plates need to be installed : aluminum-magnesium alloy material combines lightweight and strength, but it is necessary to pay attention to the professionalism of installation to avoid affecting heat dissipation and engine sinking.
The main function of the engine guard plate is to protect the engine and key components from scratches and sand erosion. Whether it needs to be installed depends on the driving scenario.
The function of the guard plate
Youdaoplaceholder0 Anti-scraping : It can prevent the chassis from colliding with crushed stones and potholes on the road surface, reducing the risk of damage to components such as the engine oil pan and transmission.
Youdaoplaceholder0 Anti-corrosion : Prevent liquids such as mud water and snow water from seeping into the engine compartment to avoid rusting of metal parts.
Youdaoplaceholder0 Keep clean : Prevent the mud and sand lifted by the tires from accumulating in the engine compartment, thereby extending the service life of the components.
Installation suggestions
Youdaoplaceholder0 frequently running on bad roads/construction sites : It is recommended to install, especially for models that do not come with protective plates from the factory (for example, some models only have resin or plastic protective plates from the factory). Steel plates or aluminum-magnesium alloy materials can be chosen to enhance protection.
Youdaoplaceholder0 Urban commuting : The original factory resin/plastic guard plate is sufficient to deal with daily scratches and does not require additional installation.
Youdaoplaceholder0 Material selection : Avoid inferior steel plates (prone to deformation and abnormal noise), and give priority to aluminum-magnesium alloy (high strength and good heat dissipation) or high-quality steel plates.
Precautions
Installation must ensure that it does not affect the engine sinking technology (the engine must be allowed to sink in case of collision).
Adding guard plates later may increase the weight, but for regular products, the impact on heat dissipation is relatively small.
Whether the upper guard plate of the engine needs to be replaced depends on the specific situation if it is damaged.
Minor damage can be temporarily left unreplaced
If the guard plate only has small holes and the frame has not fallen off, it does not affect normal driving and can be temporarily not replaced. This kind of situation is more common in resin material guard plates, which can still play a certain role in resisting minor scratches and dust prevention.
Severe damage requires timely replacement
If the guard plate shows cracks, deformation or extensive damage, especially when frequently driven on bumpy and muddy sections, it should be replaced immediately. A damaged guard plate may expose the bottom of the engine, increasing the risk of collision and the probability of foreign object intrusion.
Suggestions for material selection
Youdaoplaceholder0 resin/plastic guard plate : lightweight but with limited protective capacity, suitable for urban road use
Youdaoplaceholder0 Metal guard plates (such as manganese steel, aluminum alloy) : they have stronger impact resistance, but attention should be paid to the installation gap (it is recommended to leave a heat dissipation gap of more than 5cm) to avoid affecting the engine sinking
