Engine protection plates made of aluminum alloy offer the best cost-performance ratio, being lightweight, high-strength, and affordable, making them a top choice for consumers. Plastic protection plates have low manufacturing costs and are the lightest option. Steel and plastic-steel plates are mostly used on high-intensity off-road vehicles, while installing such plates on regular cars and urban SUVs may increase fuel consumption. Below is related information about engine protection plates: Function of Engine Protection Plates: An engine protection plate is a protective device for the engine, equivalent to adding a protective layer to the car's chassis. Of course, the design of engine protection plates varies for different vehicle models. When driving on uneven or gravel roads, there is often concern about stones or debris hitting the engine. Installing a protection plate can help safeguard the engine. Materials for Engine Protection Plates: Common engine protection plates can be categorized into steel, aluminum alloy, plastic-steel, and plastic materials. Steel plates offer strong impact resistance but are heavy and prone to noticeable noise resonance. Aluminum alloy plates are lightweight but lack high strength, making them difficult to reset after collisions and susceptible to resonance. Plastic-steel, whose main chemical component is modified polymer alloy plastic-steel (also called modified copolymer PP), has excellent properties, easy processing, and wide applications. Due to its physical properties such as rigidity, elasticity, corrosion resistance, and superior aging resistance, it is often used as a substitute for non-ferrous metals like copper, zinc, and aluminum. It does not hinder the engine's sinking function during collisions. Plastic plates are lightweight and inexpensive but prone to damage.

I've been driving off-road vehicles for several years and found that steel engine skid plates are the most reliable. Mainly because they're super sturdy, able to withstand impacts from rocks and branches, preventing engine damage. When there are many rough pits on the road, steel plates can handle the impact and offer much better protection. Although they're a bit heavier and might increase fuel consumption slightly, they're also useful for city driving, such as preventing scrapes from speed bumps. They're relatively affordable, easy to install, and suitable for all kinds of road conditions. Plastic ones are lighter but prone to breaking; aluminum is light but not as tough as steel. Overall, steel's durability makes it a more worthwhile investment. Regularly cleaning snow and mud from under the skid plate can extend its lifespan. In short, for safety first, choose steel.

When encountering traffic lights or other reasons for stopping, stepping on the brake will automatically shut down the engine; 3. To restart, release the brake and press the accelerator, or turn the steering wheel. Conditions for the engine start-stop technology to automatically cease operation include: 1. The engine is idling and not in gear; 2. The wheel speed sensor of the anti-lock system indicates zero; 3. The electronic battery sensor shows sufficient energy for the next start.

What is the reason for the frequent 5-second on-off cycling of a car's air conditioning compressor?

Car air conditioning compressor frequently cycling on and off every 5 seconds is caused by: 1. The air conditioning compressor being too cold or too hot; 2. Triggering of the overcurrent protection mechanism; 3. The relay's setting limit being too high. The reasons for the clicking sound from the air conditioning compressor are: 1. Damaged electromagnetic clutch or internal wear of the compressor; 2. Refrigerant leakage; 3. Damaged compressor capacitor or other circuit faults. Functions of car air conditioning: 1. Control the temperature inside the vehicle; 2. Remove humidity from the air, creating a comfortable driving environment; 3. Can intake fresh air to maintain air freshness inside the vehicle; 4.
