What is the function of an engine guard plate?

[VonSavannah]

The function of an engine guard plate is to: maintain the cleanliness of the engine compartment, preventing road water and dust from entering; protect the engine from being struck by gravel and hard objects kicked up by tires during driving, as such impacts can damage the engine. The lower guard plate shields the engine oil pan and also helps to flatten the vehicle's chassis, allowing air to flow more smoothly underneath. This improves stability during high-speed driving. Engine guard plates are custom-designed protective devices for various vehicle models. Their primary purpose is to prevent mud from encasing the engine, which could lead to poor heat dissipation. Additionally, they safeguard the engine from impacts caused by uneven road surfaces during driving, thereby extending the engine's lifespan and avoiding breakdowns due to external damage to the engine during travel.
