pcv heater is the heater of the PCV valve, and the PCV valve is a valve in the crankcase ventilation system. The PCV heater is designed to prevent pipeline freezing. All car engines are equipped with a crankcase forced ventilation system. When the car engine is running, gases will enter the crankcase through the piston rings. The crankcase forced ventilation system can discharge the gases in the crankcase into the intake manifold, allowing these gases to re-enter the combustion chamber for participation in combustion. This not only avoids environmental pollution but also prevents excessive pressure in the crankcase. The crankcase forced ventilation system is very important for the engine.

Is Driving a New Car at 120 km/h on the Highway Harmful?

Driving a new car at high speeds on the highway can be harmful, and it is not recommended unless absolutely necessary. If you must drive a new car on the highway, avoid staying in one gear for extended periods. Change your speed and gear every few minutes to allow all gears to break in evenly and reduce excessive wear on any single gear. Additional Notes: 1. Gearbox Control: Just like the internal components of the engine, the parts inside the gearbox also need to break in. Shift gears frequently to ensure all gears are properly run-in. Driving on various complex road conditions can help. For manual-automatic transmissions, it is advisable to switch between manual and automatic modes often. 2. Avoid Emergency Braking: During the break-in period, frequent hard braking can cause uneven wear on the brake pads, leading to issues like noise and vibrations, as reported by many car owners. These problems may stem from improper break-in practices. Typically, within the first 300 kilometers, try to avoid emergency braking as much as possible.

Why Does the BMW Wiper Make Abnormal Noises?

BMW wipers making abnormal noises is due to wiper angle issues. Possible reasons for wipers making abnormal noises: If the angle of the wiper is problematic, it can also cause abnormal noises. When the wiper ages, it may undergo slight deformation, causing the wiper to fit either too tightly or too loosely against the windshield, both of which can produce abnormal noises. Additionally, if small debris or sand particles get trapped between the wiper and the glass, the wiper will make abnormal noises during operation. In such cases, spraying windshield washer fluid multiple times to rinse away the debris will usually eliminate the noise. Wiper angle issues: If the angle of the wiper is problematic, it can also cause abnormal noises. When the wiper ages, it may undergo slight deformation, causing the wiper to fit either too tightly or too loosely against the windshield, both of which can produce abnormal noises.

How does the Teana fatigue driving reminder work?

Teana fatigue driving reminder is intelligent detection. Fatigue driving alert: It is a driver fatigue monitoring and warning product based on the physiological reaction characteristics of the driver, improving driving safety. Fatigue driving alert system: Based on the driver's physiological image response, it consists of two major modules: ECU and camera. Using the driver's facial features, eye signals, head movements, etc., it infers the driver's fatigue state and provides alarm prompts and takes corresponding measures, offering active and intelligent safety protection for drivers and passengers. Fatigue recognition system: It records the driver's operating behavior from the beginning of the drive and can determine the driver's fatigue level by identifying changes in driving operations during long-distance travel. A decrease in the frequency of steering operations by the driver, accompanied by slight but abrupt steering actions to maintain the driving direction, is a typical manifestation of driver inattention.
