What is the principle of run-flat tires?

It is mainly due to the thickened rubber sidewalls. Even when air pressure is lost, the sidewalls can still support the weight of the vehicle without causing severe deformation. Therefore, a tire blowout will not significantly affect the vehicle's driving, and the owner might not even notice it. Here is some relevant information: 1. Run-flat tires are technically called "tire pressure monitoring systems." The English abbreviation is RSC. The inflated tire sidewall is the main part that supports the vehicle's weight, especially for tires with a larger aspect ratio (the ratio of tire height to width). The sidewalls are very "thick," and a severe "blowout" usually causes the sidewall to collapse instantly, causing the tire to lose support immediately. This leads to an instant change in the vehicle's center of gravity, especially in the case of a front-wheel blowout in front-wheel-drive vehicles. The sudden shift in the center of gravity after a blowout can easily cause the vehicle to lose control. 2. The biggest advantage of run-flat tires is that in the event of a tire leak, even if the air pressure is completely lost, the vehicle can continue to drive at a speed of 80 km/h without the need for immediate tire replacement.

How to Perfectly Solve the Low-Speed Jerking Issue in Peugeot 408?

Repairing the valve body, replacing friction plates and pistons, as well as faulty solenoid valves, and thoroughly cleaning the interior of the transmission can resolve the low-speed jerking issue in the Peugeot 408. There are many reasons for jerking during low-speed acceleration in cars, such as excessive carbon buildup, incomplete fuel combustion, and spark plug malfunctions. Carbon deposits in the throttle body, fuel injectors, and intake manifold are common. Many faults caused by carbon deposits can lead to jerking sensations in some vehicles, so it is recommended to regularly clean carbon deposits. Poor fuel quality can also result in incomplete combustion. Faults in spark plugs, ignition coils, etc., can cause cylinder misfires. In such cases, it is necessary to have the vehicle inspected and repaired at a service center to avoid further safety hazards. Here is some relevant information about the Peugeot 408: Engine: The Peugeot 408 is a compact car under the Peugeot brand, equipped with two types of engines: a 1.2-liter turbocharged engine and a 1.6-liter turbocharged engine. The 1.2-liter turbocharged engine delivers 136 horsepower and a maximum torque of 230 Nm, with a maximum power output at 5,500 rpm and a maximum torque range between 1,750 and 3,500 rpm. This engine features CVVT technology and direct fuel injection, and it uses an aluminum alloy cylinder head and block. It is paired with a 6-speed dual-clutch transmission. Suspension: The Peugeot 408 uses a MacPherson independent suspension for the front and a torsion beam non-independent suspension for the rear. The use of a torsion beam rear suspension helps to expand rear passenger space and trunk capacity.

When Should I Change the Oil for My New Car?

The first oil change for a new car should occur when the mileage reaches between 1,000 to 1,500 kilometers. This mileage range corresponds to the break-in period of the car, which refers to the initial driving phase after purchasing a new car or completing a major overhaul. This period ensures that the components fully contact, friction, adapt, and settle. During this time, the car's parts can adjust and enhance their ability to adapt to the environment, while also wearing down any rough surfaces on the components. Key factors to consider when choosing engine oil: Select engine oil based on the requirements of the engine. There is no need to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. Precautions for changing engine oil: The engine must be warmed up before draining the oil. This is because the oil becomes thinner when warm, making it easier to flow and carry away impurities, which helps in completely draining the oil. Never drain the oil when the engine is cold. Additionally, the oil filter should be replaced simultaneously. An old oil filter may become clogged with impurities, slowing down oil flow and reducing engine lubrication. When refilling oil, ensure the quantity is accurate. For some vehicles, the oil level can be checked using the dipstick to determine if it is appropriate. Functions of engine oil: The primary function of engine oil is lubrication. During the lubrication process, the oil is gradually consumed, and impurities and deposits may form, affecting its effectiveness. Engine oil also has a cleaning effect, but some residues may remain in the engine. The anti-rust property of engine oil is crucial as well. While oil cannot completely prevent oxidation, it can reduce it. Good sealing enhances mechanical efficiency, but prolonged use of oil can lead to chemical reactions that weaken sealing. Cooling is another function of engine oil, but its cooling effect diminishes over time with prolonged use.

Does the Honda CR-V have a particulate filter?

The gasoline-powered Honda CR-V is equipped with a particulate filter, while the hybrid version does not have one. A particulate filter is a ceramic filter installed in the diesel engine's emission system that captures particulate emissions before they enter the atmosphere. It can reduce soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. Diesel engine pollution mainly comes from three sources—particulate emissions, hydrocarbons (HCx), nitrogen oxides (NOx), and sulfur. Among these, particulate emissions (soot) mostly consist of tiny particles of carbon or carbon compounds (smaller than 4-20μm in size). How the particulate filter works: The diesel particulate filter is coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the exhaust particulate filter through a dedicated pipe. After passing through its densely arranged bag-type filter, the carbon soot particles are adsorbed onto a filter made of metal fiber felt. When the amount of adsorbed particles reaches a certain level, the burner at the end automatically ignites, burning off the carbon soot particles adsorbed on it and converting them into harmless carbon dioxide that is then expelled. To check whether the CR-V has a particulate filter, you can use the following three methods: Check the and to see if there is a particulate filter function. Additionally, carefully review the fault codes in the manual to see if there is a "particulate filter" warning light indicator. Check the label on the oil cap. If the oil cap clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. Look behind the three-way catalytic converter to see if there is a cylindrical section on the exhaust pipe. If there is, that is the particulate filter.

How to Use Cold Patch Film?

Apply glue to the sanded area, and when the glue is almost dry, attach the patch film. When attaching the patch film, be careful to do it correctly the first time, as it won't stick well if you try to reposition it.

How to Install Wiper Blades of Different Lengths?

Generally, the longer wiper blade should be installed near the driver's side by aligning it with the mounting clip. The shorter wiper blade is installed on the passenger side. Locate the wiper mounting clip on the left side of the passenger side, then place and secure the wiper blade onto it.
