What is the lower guard plate of a car engine
Engine guard plates are engine protection devices tailor-made for various vehicle models. Their design is primarily to prevent dirt from covering the engine and secondly to prevent damage to the engine caused by impacts on uneven roads during driving.
Through a series of designs, the service life of the engine is extended to prevent the car from breaking down due to engine damage caused by external factors during travel.
Whether it is necessary to install an engine lower guard plate depends on the actual driving environment : It is recommended to install it when frequently driving on complex road conditions (such as unpaved roads, gravel roads, etc.), which can effectively protect the engine. If one mainly drives on flat urban roads, the necessity is relatively low.
Youdaoplaceholder0 Definition and function of engine lower guard plate
The engine lower guard plate is a protective device installed at the bottom of the engine. Its main functions include:
Engine protection : Prevent mechanical damage such as oil pan rupture caused by bottoming out, sand and gravel impact or foreign object intrusion.
Youdaoplaceholder0 Anti-rust and anti-fouling : Prevents mud, water and dust from entering the engine compartment, reduces corrosion and keeps it clean.
Youdaoplaceholder0 Performance optimization : Some guard plates can reduce the wind resistance of the chassis, improve fuel economy and driving stability.
The main drawbacks of engine guard plates include affecting heat dissipation, increasing fuel consumption, hindering the engine's sinking safety mechanism, causing abnormal noises and accumulating dirt. The pros and cons need to be weighed based on the driving scenario.
Youdaoplaceholder0 Main harms analysis
Youdaoplaceholder0 heat dissipation impact : The guard plate may impede the air flow in the engine compartment, leading to poor heat dissipation. Especially in high-temperature areas or urban congested roads, it may cause the engine temperature to rise by more than 10℃, accelerating the aging of components.
Youdaoplaceholder0 Increased fuel consumption : Heavier material guard plates (such as steel plates) will increase the vehicle weight (about 5-10 pounds), and long-term use may reduce fuel efficiency, consuming tens of liters of additional fuel each year.
Youdaoplaceholder0 Safety hazard : In severe collisions, the guard plate may impede the engine sinking design (to prevent the engine from entering the cab), increasing the risk of passenger injury. The problem with steel guard plates is particularly prominent.
Youdaoplaceholder0 Abnormal noise and dirt deposition : Improper installation can easily cause resonance abnormal noise; Stones and dust are prone to accumulate on the surface of the guard plate, which may get stuck in the gaps of the components, causing damage or noise. Regular cleaning is required.
Youdaoplaceholder0 other potential problems
Improper material selection : Inferior steel plates may deform and make abnormal noises, aluminum-magnesium alloys are expensive, and hard plastic resins have insufficient strength.
Youdaoplaceholder0 Application scenario limitations : For urban paved roads, additional installation is usually not required; the original factory guard plates are sufficient. Non-professional guard plates may overheat or even spontaneously combust due to design flaws.
Youdaoplaceholder0 installation suggestions
Give priority to choosing professionally designed guard plates with ventilation holes to ensure that installation does not affect engine sinking.
For frequent off-roading or driving on bad roads, lightweight materials (such as aluminum-magnesium alloy) can be considered. No additional installation is required for urban driving.
