What is the appropriate tire pressure for a car?

Under normal circumstances, the recommended tire pressure for cars is 2.5 kgf/cm² in winter and 2.2 kgf/cm² in summer. The maximum allowable tire pressure is indicated on the sidewall of the tire. Generally, a reasonable tire pressure is 70% to 80% of the maximum pressure marked on the tire, but it is best not to exceed the maximum pressure indicated. Below are relevant details about car tire pressure: 1. If the car is fully loaded (5 people), adjusting the tire pressure to around 2.5 kgf/cm² is more suitable. For two passengers, a tire pressure of 2.3 kgf/cm² is also normal. 2. For daily tire use, it is important to pay attention to tire pressure. Generally, cars travel at high speeds, and the shape of the tire undergoes high-frequency alternating changes. If the pressure is insufficient, deformation increases, causing excessive wear on the tread edges. The tire body may twist and deform due to inability to withstand ground pressure, generating heat and accelerating tire wear, ultimately leading to a blowout. 3. Excessive pressure can also make the tire too rigid, losing its necessary elasticity and shock absorption capacity. This not only reduces grip but also causes uneven tread depth due to excessive wear in the central tread. Tires operating at high speeds may also fail to withstand excessive expansion pressure, leading to a blowout. Therefore, both overinflation and underinflation pose blowout risks, and tire pressure should not be overlooked. Always maintain the standard tire pressure as recommended by the manufacturer, including the spare tire pressure.

What to Do When a Car Belt Slipping?

Solutions for car belt slipping: 1. Add counterweights when the belt conveyor slips until the belt no longer slips; 2. Adjust the tension stroke to increase the tension force; 3. Re-vulcanize or increase the tension stroke; 4. Adjust the tensioning device to increase the initial tension; 5. Timely maintenance and replacement of the tail roller bearings. The belt is an important part of the engine's valve timing system, ensuring accurate intake and exhaust timing by connecting to the crankshaft and maintaining a certain transmission ratio. Belts are used instead of gears for transmission because they produce less noise, have minimal self-variation, and are easier to compensate.

How to Use Windshield Wipers?

Windshield wipers are used as follows: By pushing the control lever up and down, you can control the wiper's operation modes (intermittent, off, auto, and low/high speed). If set to automatic mode, you can adjust the sensitivity of the rain-sensing wiper control by rotating the adjustment knob, thereby changing the wiper's operating frequency. Information about windshield wipers is as follows: 1. Windshield wipers (WINDSHIELD-WIPER) are blade structures installed in front of the windshield, consisting of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly. Their main function is to clear rain, snow, and dust from the windshield that obstruct the driver's view. 2. The power source of windshield wipers comes from the motor, which is the core of the entire wiper system.

How Often Should Car Gear Oil Be Changed?

Under normal circumstances, gear oil should be changed every 60,000 kilometers. Here is some relevant information: 1. Changing gear oil can effectively improve the efficiency of gear transmission of engine power. The selection of oil viscosity is the most basic factor in choosing gear oil. If the viscosity is too high, it can cause overheating of the friction surfaces and unnecessary power loss. 2. The commonly used steels for manufacturing car gears include tempered steel, quenched steel, carburized and quenched steel, and nitrided steel. The strength of cast steel is slightly lower than that of forged steel and is often used for larger gears; gray cast iron has poorer mechanical properties and can be used in lightly loaded open gear transmissions; ductile iron can partially replace steel in gear manufacturing; plastic gears are mostly used in lightly loaded applications where low noise is required, and the paired gears are usually made of steel with good thermal conductivity.

Why does the car feel bumpy when driving on a flat road?

Reasons why a car feels bumpy when driving on a flat road: 1. Suspension system failure causes the car to feel bumpy when driving on a flat road. When the hydraulic shock absorber fails, the repeated extension of the spring will not be suppressed, causing the car to bounce up and down, resulting in a bumpy feeling; 2. Tire imbalance causes the car to feel bumpy when driving on a flat road. The quality of the steel rim and rubber tire cannot be completely uniform, and when rotating at high speed, it will shake violently, resulting in a bumpy feeling; 3. Four-wheel misalignment causes the car to feel bumpy when driving on a flat road. The wheel angles of a new car are preset when leaving the factory, but as the mileage increases and the suspension is repeatedly stressed, these angles will change slightly. When these angles change, the tire contact surface and the car's thrust line will change, causing the car to feel bumpy when driving on a flat road.

How Often Should You Clean Your Car's Fuel Injectors?

Car fuel injectors should be cleaned approximately every 30,000 kilometers. If the vehicle is in good condition and high-quality fuel is used, cleaning can be extended to every 40,000 to 60,000 kilometers. Fuel injectors are not consumable parts and do not require frequent replacement or cleaning; excessive cleaning may actually lead to premature failure. Even if the injectors are slightly clogged, there's no need to panic, as impurities can be flushed away and burned off during high-gear acceleration, restoring normal vehicle performance. It's recommended to drive on highways for this purpose. A car's fuel injector is essentially a simple solenoid valve: when the electromagnetic coil is energized, it creates a magnetic pull that lifts the needle valve, opening the injection port. Fuel is then sprayed at high speed through the annular gap between the needle valve head and the injection port, forming a fine mist that facilitates complete combustion.
