Summer tire pressure of 2.7 is very high. According to the international GBT2978-2008 standard, the standard tire pressure for standard tires is 2.4-2.5 bar. A pressure of 2.7 bar exceeds the maximum value of the standard tire pressure, so it is abnormal. Generally, the lower limit of the standard tire pressure for car tires is sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures. Hazards of excessive tire pressure: The friction and adhesion of the tire will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Causes excessive stretching and deformation of tire cords, reducing tire elasticity and increasing the load on the car during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks and blowouts due to impact.

How Long Does It Take for Engine Salt to Take Effect?

After salt is added to the transmission lubricating oil, the salt will coagulate inside the transmission, forming "paste sheets" that continuously wear down the components. When the wear reaches a certain level, the friction plates in the transmission will need replacement, and the entire transmission may also be damaged. Under normal circumstances, this wear process takes 1 year or even several years, but adding salt can shorten this process to a few months or even weeks. Here is additional information: Consequences of adding salt: Salt is highly corrosive to bearings and piston rings. The effects may not be noticeable in the short term, but prolonged exposure can lead to engine failure. There are also many cases where sugar or alcohol is added to the engine. When heated, sugar turns into a sticky paste but provides no lubrication, and the damage may go unnoticed by others. The consequences include rapid loss of engine power, insufficient performance, and even complete engine failure.

How Often Should Engine Spark Plugs Be Replaced?

Ordinary nickel alloy spark plugs should be replaced approximately every 20,000 kilometers, platinum spark plugs around every 40,000 kilometers, and iridium spark plugs every 60,000 to 80,000 kilometers. Below is relevant information: 1. Spark plugs are a crucial component of the ignition system in gasoline engines. They introduce high voltage into the combustion chamber, causing a spark to jump across the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. 2. A spark plug mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell, with the side electrode welded to the shell. Spark plugs are mounted on the side or top of the engine. In earlier designs, spark plugs were connected to the distributor via ignition cables, but over the past decade, most car engines have switched to direct connection between the ignition coil and the spark plug.

Does the activated carbon cabin air filter have a front and back side?

Activated carbon cabin air filters do have a front and back side. Here is the relevant information: 1. The orientation of the activated carbon cabin air filter is determined by the blower. The filter is installed inside the glove compartment. Turn on the AC and observe the blower's airflow direction: If the air blows upward, the black activated carbon side should face downward; if the air blows downward, the black activated carbon side should face upward. The black side is the intake side, while the white HEPA cotton side is the outlet side. 2. As the name suggests, a dual-effect activated carbon cabin air filter combines the ability to filter dust with the activated carbon's capability to adsorb harmful gases. The dual-effect structure consists of two parts: filter fabric + activated carbon.

Why is there water leakage under the car steering wheel?

The cause is a leak due to damage to the air conditioning condensate pipe. Here is relevant information about the car steering wheel: 1. Definition: The wheel-shaped device used to control the direction of the car, which converts the force applied by the driver to the edge of the steering wheel into torque and transmits it to the steering shaft. 2. Grip method: If the steering wheel is viewed as a clock face, the correct hand position is left hand between 9 and 10 o'clock, and right hand between 3 and 4 o'clock. In the event of a collision, this posture is more conducive to supporting the body. 3. Material: The frame is generally made of zinc alloy or aluminum alloy. Some manufacturers are experimenting with cheaper and lighter magnesium alloys. The frame is produced by die-casting. A small number of manufacturers still use steel sheet metal for the frame, which has a complex structure.
