When the engine is idling stably, the standard oil pressure value is normal within the range of 200kPa to 500kPa. Below is relevant information about engine idling operation: 1. Description: The reading on the oil pressure gauge during engine idling represents the idle working pressure of the fuel supply system, generally 0.25MPa or as specified by the vehicle's technical requirements. When testing the idle working pressure, if the oil pressure does not rise to 0.3MPa after removing the vacuum tube from the fuel pressure regulator, the pressure regulator should be replaced. 2. Precautions: While the engine is running, regularly check the values on the oil pressure gauge and coolant temperature gauge. If the oil pressure and coolant temperature values differ significantly from the usual readings, immediately stop the engine for inspection or contact an automotive service center.

Which Type of Car Transmission is the Best?

Globally recognized best car transmissions are specifically introduced as follows: 1. BMW's 8AT Transmission: It is known that for BMW, one of the three giants of German cars, its handling and driving experience have reached an impeccable level. Combined with ZF's AT transmission technology. 2. Nissan's CVT Continuously Variable Transmission: In today's transmission field, when it comes to intelligence, CVT is undoubtedly the leader. Moreover, CVT has no sense of discontinuity when shifting gears, is very smooth, and has very low noise. 3. Volkswagen's DSG Dual-Clutch Transmission: It is known that Volkswagen started the earliest in the development of DSG. While many companies were focusing on manual-automatic transmissions, Volkswagen began developing DSG. However, Volkswagen indeed succeeded. With the same displacement, Volkswagen's DSG transmission can achieve higher power, making it very excellent.

What Causes the Car Ignition Lock Cylinder to Not Turn?

Car ignition lock cylinder may not turn due to sticky lock pins, a stuck key and wafer, or a locked steering wheel. Here is relevant information: 1. LOCK: The lock position, which must be engaged when parking and turning off the engine. Only in this position can the key be removed. If the steering wheel is turned at this time, the steering wheel will also lock. The next time you start the car, you need to turn the steering wheel while twisting the key; otherwise, the key won't turn. 2. ACC: Accessory position. When engaged, only a few components receive power, such as the radio and cigarette lighter. 3. ON: Full power position. When engaged, all vehicle components receive power. This is the position used during normal driving. 4. START: Start position. This position is only used when starting the engine. After the engine starts, releasing the key will automatically return it to the ON position.

Should the handbrake be applied during parallel parking?

After completing parallel parking, it is necessary to apply the handbrake. Below are relevant details: 1. Parallel Parking: Parallel parking is becoming increasingly common in urban areas, especially as parking spaces in formal parking lots become more scarce. Many places have designated parking spaces along the sides of streets, creating "parallel parking spots." 2. Handbrake: Officially known as the parking brake. Currently, there are mechanical and electronic types. Its function is to secure the vehicle after parking to prevent it from rolling. 3. Precautions: Shift into R gear, slowly release the clutch, and ensure the vehicle speed is very slow. When the small window of the rear door or the No. 1 marker pole (the left pole at the front of the garage) aligns with the rear wheel, press the clutch firmly, avoid braking, and do not pause for too long.

What are the reasons for crossing the right boundary line during a 90-degree turn?

The reasons for crossing the right boundary line during a 90-degree turn are as follows: 1. Reasons for crossing the line: The speed is too fast, as excessive speed makes it difficult to control the vehicle body, leading to easily crossing the corner or line; Initial position, before turning, the distance between the vehicle body and the inner boundary line should not be too close, otherwise insufficient reserved space may cause crossing the line. 2. The correct method to avoid crossing the line during a 90-degree turn: Before entering the turn, drive close to the right side first. When the inner corner of the 90-degree turn aligns with the driver, start turning the steering wheel to the left. When the left rear wheel of the car aligns with the inner corner line of the 90-degree turn, the steering wheel should be turned to the maximum. Once the left rear wheel passes the inner corner line, begin gradually turning the steering wheel back to the right. After the steering wheel is straightened, drive out of the turn.

What are the methods for exhaust gas treatment?

Methods for exhaust gas treatment include: 1. Improving existing automotive power units and fuel quality: Diesel engines are preferred where possible. From a purely pollution perspective, both diesel and gasoline vehicles produce emissions, but without any mitigation measures, gasoline vehicles are more polluting. This is because gasoline vehicles emit higher levels of carbon monoxide (CO), carbon dioxide (CO2), and hydrocarbons (HC) compared to diesel vehicles. 2. Engine tuning: Reducing the injection timing advance angle lowers the engine's peak operating temperature (1500°C), thereby decreasing NOx formation. Enhancing injector quality and controlling combustion conditions (air-fuel ratio, combustion temperature, duration) ensures more complete fuel combustion, reducing CO, HC, and soot emissions. 3. Exhaust after-treatment measures: Advanced after-treatment technologies are widely adopted to purify vehicle exhaust and minimize pollution effectively. These technologies involve installing various purification devices in the exhaust system that utilize physical and chemical methods to reduce pollutants.
