What Are the Hazards of Installing Mudguards on Cars?

Installing mudguards can lead to reduced vehicle passability, increased aerodynamic drag, and increased tendency for the car to drift. The specific explanations are as follows: Reduced Vehicle Passability: Installing mudguards can affect the vehicle's passability to some extent, especially for models with already low ground clearance. Increased Aerodynamic Drag: Related studies have found that installing mudguards increases turbulence at the rear of the car compared to the original model, resulting in greater resistance. The faster the speed, the quicker the resistance increases. Therefore, to reduce aerodynamic drag, cars are designed with a streamlined shape during development, and the underside is made very flat to allow air to flow quickly, significantly reducing the drag coefficient. Installing mudguards can increase the total drag by about 5%. Assuming other conditions remain the same, fuel consumption would increase by 5%, along with some additional noise. Increased Tendency for the Car to Drift: Greater aerodynamic drag also means that at high speeds, the airflow velocity slows down. According to Bernoulli's principle, the aerodynamic lift on the car also increases, making the car feel more prone to drifting during driving. Researchers conducted experiments on a certain car model, finding that at a speed of 80 kilometers per hour, the aerodynamic lift increased by 57.1% when mudguards were installed.

What Causes Jerking at Speeds Above 100 km/h?

There may be three reasons for jerking at speeds above 100 km/h. The specific explanations are as follows: 1. Carbon deposits: Excessive carbon buildup in the throttle body, fuel injectors, or intake manifold. Since the key components of carbon deposits are wax and gum deposits from fuel, it is best to minimize the gum content in fuel. Carbon deposits can cause various malfunctions, and some vehicles may experience jerking due to carbon deposits. It is recommended to regularly clean carbon deposits. 2. Fuel: Poor fuel quality leading to incomplete combustion. While you cannot change the quality of the fuel, avoid using low-quality fuel of unknown origin. 3. Electrical faults: Issues with spark plugs, ignition coils, etc., causing misfires. These need to be inspected and repaired promptly to avoid further safety hazards.

What is the difference between car heat insulation film and explosion-proof film?

Specific differences are as follows: 1. Analysis of car sun film: Car sun film refers to the film pasted on the surface of car glass, commonly known as sun film. In addition to heat insulation and light blocking, it also has explosion-proof functions. High-quality explosion-proof film uses special polyester film as the base material, which itself has strong toughness and is combined with special pressure-sensitive adhesive. In case of accidents, the glass will not shatter and cause injury after being broken. Car explosion-proof film also has the functions of one-way perspective and reducing glare. 2. Analysis of car explosion-proof film: Car explosion-proof film is the highest level of safety film, that is, explosion-proof film products. It adds a layer of protection to car glass to prevent glass from shattering and fix broken glass fragments when colliding with the outside world, providing certain protection for the personal safety of the car owner. 3. Differences between car sun film and explosion-proof film: (1) Differences in material structure and thickness: The thickness of safety film is between 100-175 microns (about 4-7mil), while car explosion-proof film is a multi-layer polyester composite film made by special lamination process, with a thickness of more than 250 microns (about 10mil). Thickness is a hard indicator to distinguish safety film from security film. (2) Differences in protection level and concept: Sun film is mainly made of the original PET material and magnetron sputtering technology, and its function is to insulate heat and control harmful light, that is, to block infrared and ultraviolet rays. The design of explosion-proof film can absorb explosion shock waves and resist stronger energy impacts. High-end explosion-proof film combined with glass can even reach the bulletproof level, and its protection function covers the effect of safety film while reaching the level of safety explosion-proof. (3) There are obvious differences in the implementation standards: The standard that car sun film can generally achieve is the level standard of blocking ultraviolet rays, while the detection standard of explosion-proof film is based on preventing penetration, that is, when the glass is hit, the glass can be broken, but the explosion-proof glass film layer cannot be penetrated.

How to Open the Car Door When the Entire Vehicle Has No Power?

If it is a conventional folding key, you can directly use the mechanical key to open the door when there is no power. The basic components of a remote key are as follows: 1. Transmitter: Composed of a transmission switch, transmission antenna, integrated circuit, etc., it includes an identification code storage circuit and an amplitude modulation modulation circuit, with a button-type lithium battery installed on the opposite side of the circuit. The transmission frequency uses radio waves, and each press of the transmission switch button sends a signal once; 2. Receiver: After the transmitter sends the identification code using shortwave modulation, it is received by the car's shortwave antenna and enters the shortwave high-frequency amplification processor of the receiver's electronic control unit through a distributor for demodulation, where it is compared with the demodulator's identification code.

Why Doesn't Beijing Use Ethanol Gasoline?

Beijing is not avoiding ethanol gasoline, but it has not yet been widely adopted. Here is an expanded explanation: 1. Introduction to Ethanol Gasoline: Ethanol gasoline refers to the addition of 10% (in China) of fuel ethanol (commonly known as alcohol) to regular unleaded gasoline. In simple terms, it is gasoline blended with 10% biofuel ethanol. It is typically denoted by the letter 'E' following the gasoline octane rating, such as E92#, E95#, and E98#. 2. Disadvantages of Ethanol Gasoline: Ethanol has a lower calorific value than conventional gasoline, approximately 60% of regular automotive gasoline, which can increase engine fuel consumption by 5%. Additionally, it reduces vehicle performance, fuel economy, and cold-start capability, negatively impacting acceleration. 3. Advantages of Ethanol Gasoline: The ethanol in ethanol gasoline is a renewable resource with mature technology. It burns more completely, effectively reducing harmful exhaust emissions and benefiting environmental protection. Ethanol gasoline also has excellent cleaning properties, effectively eliminating the deposition and coagulation of fuel impurities in the fuel tank and fuel system.

What Causes the Vibration When Turning on the AC in an 8th Generation Accord?

Vibration when turning on the AC in a car is generally caused by carbon buildup on the spark plugs, carbon buildup on the throttle body, or a deformed fan or loose screws. Below is a detailed explanation of the reasons for vibration when turning on the AC: 1. Carbon buildup on spark plugs: After a period of use, carbon deposits will accumulate on the spark plugs. If not cleaned in time, this can reduce the engine's torque output, leading to vibration when the AC is turned on. Soak the spark plugs in a container with white vinegar for 2-3 hours (or 4-5 hours for severe cases), then use a stiff brush to remove the carbon deposits. Clean them with gasoline and let them air dry naturally. 2. Carbon buildup on the throttle body: When the AC is turned on, the engine load suddenly increases, and the throttle opening expands. At this point, the issue of dirt is magnified. If the throttle is stuck or fails to open to the proper position, the air intake is restricted, reducing engine power and eventually causing engine vibration. 3. Deformed fan or loose screws: Check if the vibration is due to resonance caused by a deformed fan when the AC is turned on or if it's caused by loose screws securing the fan.
