What is the normal oil pressure for a car?

The normal gasoline pressure for a car is around 280 kilopascals (kPa). Some engines with direct injection technology may have even higher gasoline pressure. There are three types of fuel injection methods in cars: direct injection, multi-point fuel injection, and hybrid injection. Engines with multi-point fuel injection have injectors located in the intake manifold, while engines with direct injection have injectors inside the cylinders. Hybrid injection refers to a system that combines both direct injection and multi-point fuel injection. Engines equipped with hybrid injection technology can choose different fuel injection methods under different operating conditions, which helps improve engine power and efficiency.

What is the sidewall thickness of BMW run-flat tires?

BMW run-flat tires have a sidewall thickness of 12mm. Precautions for using run-flat tires: Generally, run-flat tires can still be driven at 80KM/h for 250 kilometers after a puncture (specific values are subject to the car manufacturer's regulations), which can prevent car owners from being stranded on some remote roads. However, it should be noted that when the tire damage is severe or the road conditions are poor, the driving distance may be reduced to tens of kilometers. Safety: Run-flat tires have high safety, but they reduce driving comfort, increase fuel consumption, and decrease power. However, in the face of safety, these are minor issues. The safety of run-flat tires is the primary reason why many car owners choose them.

What Causes the Airbag Light to Illuminate?

The airbag light illuminates due to an airbag malfunction. When the ignition is turned on, the airbag light should turn on for about 6 seconds and then go off, which is normal. If the airbag light remains on after starting the vehicle or while driving, it indicates a fault in the airbag system. Airbags are distributed in three directions inside the vehicle: the front (driver and front passenger seats), the sides (front and rear seats), and the roof. The exterior of containers equipped with airbag systems is marked with the words "Supplemental Inflatable Restraint System," which translates directly to "Auxiliary Inflatable Restraint System" in Chinese. Its purpose is to reduce the severity of injuries caused by secondary collisions due to inertia after a car crash.

What does the ABS indicator light on the car mean?

When the ABS indicator is displayed on a car, it means there is a malfunction in the vehicle's Anti-lock Braking System. If the wheels lock up during emergency braking, the vehicle may lose control and skid, making it difficult for the driver to slow down or adjust the vehicle's trajectory, posing significant safety risks. There are several conditions under which the ABS light may illuminate, each with different causes and solutions, as detailed below: Condition 1: ABS warning light stays on continuously (most common). Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle's speed and the wheel's slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt off the wheel speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Poor signal transmission due to loose connections in the system wiring or poor contact in the ABS relay, leading to system failure. Solution: Inspect wiring connections and reconnect any loose parts. Condition 2: ABS warning light intermittently illuminates and turns off when accelerating. Cause: When multiple electrical devices are in use, the battery voltage drops below 10.5V. As the engine speed increases and voltage rises, the ABS light turns off. The ABS system's power supply voltage is too low, possibly due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact). Condition 3: ABS warning light remains on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body; poor contact in the ABS hydraulic valve body wiring connector; ABS computer malfunction. Solution: Loosen and then retighten the grounding screw on the hydraulic valve body, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR computer. Condition 4: ABS warning light illuminates during high-speed driving. Cause: During high-speed driving, the ABS computer detects a significant discrepancy between the rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. Condition 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: With the engine running, press the brake pedal, push the brake switch linkage down fully with a finger, then release the brake pedal to complete the self-setting position; replace the brake light switch if necessary.
