What is the name of the protective plate under the car engine?

The protective plate under the car engine is called the engine guard plate. Here is some relevant information about the engine guard plate: 1. Engine guard plate: Whether it is necessary to install an engine guard plate depends on different circumstances: If you often drive on low-lying roads or gravel roads, it is necessary to install an engine guard plate; If you usually only use the car for commuting in the city, it is not necessary to install an engine guard plate. 2. Function: The engine guard plate is used to protect the engine and is generally installed under the chassis at the front of the car to prevent the engine from being bumped. Depending on the vehicle brand and model, whether the new car is equipped with an engine guard plate when it leaves the factory also varies.

Does changing the car lock cylinder have any impact on the vehicle?

No. Basically, the entire set is replaced. Additional information: 1. Things to note when changing car locks: Changing the car lock cylinder does not affect the remote lock, but the ignition key cylinder and trunk lock must also be replaced—essentially, the whole set is replaced. 2. Car anti-theft locks can be broadly categorized into three types based on technical principles: mechanical anti-theft locks, electronic anti-theft alarm locks, and networked anti-theft (positioning, tracking) systems. 3. Car anti-theft locks include: electronic car anti-theft locks, network car anti-theft locks, fuel line locks, clutch and brake anti-theft locks, wheel locks, gearshift locks, steering wheel locks, and car anti-theft magnetic plates, among others.

What Happens When a Car Runs Low on Coolant?

When the car's radiator runs low on coolant, the temperature inside the cylinders will rise rapidly. If the vehicle continues to operate, its components will be forced to work under excessive load, reducing the strength of parts such as pistons, piston rings, and connecting rods, potentially causing deformation. Additionally, the gaps between parts may be compromised, leading to minor issues like cylinder or bearing wear, or in severe cases, complete engine failure. If the car's radiator is out of coolant, a warning light shaped like a thermometer will appear on the dashboard, making it relatively easy to identify. It is not advisable to continue driving once this warning light appears. Without sufficient coolant, the heat generated by the engine cannot be dissipated, compromising its performance, durability, and emissions standards. In a cold engine state, the car may still operate for about 1-3 kilometers without coolant, but driving in a hot engine state can cause severe engine damage. If you encounter a coolant shortage while driving, never use tap water as a substitute. Tap water contains minerals that can form scale when heated in the radiator pipes, potentially clogging the engine's cooling system if severe. In emergencies, distilled water can be used as a temporary substitute for antifreeze. However, once you reach a nearby service point, you must immediately replenish the antifreeze. When adding antifreeze, ensure that any distilled water in the radiator is removed to prevent the antifreeze from deteriorating.

Can a Flooded Car Be Unlocked and the Door Opened?

No, because the water pressure is too high. When the car cabin is completely filled with water, the pressure difference between the inside and outside balances out, making it possible to open the door as if in the air. Below are the damage assessment standards for flooded vehicles: 1. Waterlogged car: The water level exceeds the car's chassis, referred to as a waterlogged car. 2. Partially flooded car: The water level exceeds the oil dipstick, known as a partially flooded car. 3. Fully flooded car: The water level exceeds the engine hood or the dashboard surface, termed a fully flooded car. Additional information: A flooded car refers to a vehicle that has been submerged in water, typically meaning the engine and transmission have been soaked, with the water depth exceeding the wheels and car seats, and the bottom components of the car body in prolonged contact with water. Such vehicles pose significant risks, as the electrical circuits are prone to short circuits and fires.

Should the Kia Sportage use 92 or 95 octane gasoline?

According to the official vehicle manual recommendation, the Kia Sportage should use 92 octane gasoline. In addition to checking the appropriate gasoline grade in the vehicle manual, you can also find it marked on the fuel tank cap of the Kia Sportage. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. However, with the application of new technologies, the compression ratio alone cannot determine the gasoline grade. High compression ratio engines can also be tuned to use lower octane gasoline due to other influencing factors such as ignition timing, turbocharging technology, and Atkinson cycle technology. Generally, the higher the gasoline octane number, the higher the octane value and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the Kia Sportage occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane value can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Due to the significantly lower octane value, the gasoline's ignition point decreases, causing premature ignition during the compression stroke. If the fuel ignites before the spark plug fires, resistance occurs during the upward stroke. This resistance makes the engine run very unstably. If the knocking is mild, it may only increase noise without significant engine damage. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

What problems will occur if the car air conditioning switch is broken?

Phenomenon: Poor contact of the contacts or abnormal operation of the pressure switch may cause the compressor to not work or fail to provide normal pressure protection. The following is a related introduction about car air conditioning: 1. Function: It is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car compartment to the optimal state, providing a comfortable riding environment for passengers, reducing travel fatigue, creating good working conditions for the driver, and serving as an important ventilation device to ensure safe driving. 2. Layout form: The layout form involves assembling the evaporator, heater radiator, centrifugal blower, control mechanism, etc., together, which is called the air conditioning unit assembly.
