What does EGR on a car mean?

EGR on a car stands for Exhaust Gas Recirculation system, which refers to the process of redirecting a portion of the engine's exhaust gases back to the intake manifold, where they mix with fresh air-fuel mixture and re-enter the cylinders. Since the exhaust gases contain large amounts of polyatomic gases such as CO2, which cannot combust but absorb significant heat due to their high specific heat capacity, the maximum combustion temperature of the mixture in the cylinders is reduced, thereby decreasing the formation of NOx. EGR primarily functions in the following ways: 1. The CO2 and water vapor in EGR significantly increase the specific heat capacity of the working fluid, while the addition of exhaust gases also dilutes the oxygen concentration in the original mixture, slowing down the combustion rate. This results in a decrease in both the peak and average temperatures during combustion, disrupting the favorable conditions for NO formation and greatly reducing NOx emissions. 2. Since gasoline engines typically regulate load through quantity control, applying EGR in gasoline engines can correspondingly increase the intake air volume. An increase in the EGR rate can reduce the throttle loss under medium and low load conditions, thereby lowering the fuel consumption rate of the gasoline engine.

What is the battery model for BMW 535?

The battery model for BMW 535 is 20-92/H8-92-L-T2-A, and the battery brand used is VARTA. Regularly clean the battery: During daily use of the vehicle, it is necessary to pay attention to the condition of the battery. After prolonged use, the battery may be covered with dust, powder, oil stains, etc. To ensure the normal operation of the battery, it is important to promptly clean the dirt on the battery panel and the positive and negative terminals to extend its service life. Avoid prolonged parking: If the vehicle is left unused for an extended period, the battery will self-discharge. Therefore, even if the car is not used regularly, it is recommended to start it once a week and take it for a short drive to ensure the battery remains fully charged. Regular inspection: The service life of a vehicle battery is typically 3-4 years. For high-end models with more electronic systems, the battery's lifespan may be relatively shorter. Therefore, regularly checking the battery's charging condition can help maintain it in optimal working condition.

Why can't the Haval H6 window be raised with one-touch?

Haval H6 window cannot be raised with one-touch may be due to incorrect settings, try resetting it. If it still doesn't work, the switch might be damaged and needs replacement. One-touch window function introduction: The one-touch window control has two gears. When you want to open the window partially, use the first gear. To fully open the window, press it all the way down, there will be a slight sound and feedback force, then the window will automatically lower. Generally, buttons with one-touch window function have anti-pinch protection. For cars frequently carrying children, it's best to have this function, and always lock all four windows from the driver's control side while driving. Definition of one-touch window: One-touch window refers to a car window system where the glass can be controlled to rise or fall to position with a single button press. With ordinary power windows, you need to hold the switch until the window reaches the desired position, then release the button to stop the movement.

Which gear is the parking gear for an automatic transmission car?

Automatic transmission cars use the P gear for parking. Automatic transmissions also have R, N, D, S, L, and M gears, each with the following meanings: First: L gear. This is the low gear. When going downhill or uphill, shifting into this gear allows better utilization of the engine's power for braking or fuel efficiency. When descending a slope, it can lower the engine speed and use the engine for braking, avoiding the need to constantly press the brake pedal hard. Second: R gear. This is the reverse gear. This gear is the same for both manual and automatic transmission cars. It is used when reversing, typically after the car has come to a complete stop before shifting into this gear. Third: N gear. This is the neutral gear. It is useful for short-term parking. It is also used in conjunction with the P gear for long-term parking. Fourth: D gear. This is the drive gear. Fifth: S gear. This is the sport gear. When shifting into this gear, the engine can provide more powerful performance. It is generally used when overtaking, as it is more fuel-efficient compared to shifting into D gear and pressing the accelerator hard. It also allows for much faster acceleration.

What is the resolution of the BMW 5 Series display screen?

The resolution of the BMW 5 Series display screen is 160×128. The dimensions of the domestically produced BMW 5 Series model are 5087mm in length, 1868mm in width, and 1500mm in height, with a wheelbase of 3108mm. Introduction to the display screen: The trip computer display screen is essentially a monitor that shows some data from the trip computer. Most trip computer displays now show data such as average fuel consumption, instantaneous fuel consumption, outside temperature, average speed, travel time, and single-trip mileage, which is very practical. Function of the display screen: The role of the trip computer display screen is to enhance certain functions that the onboard computer lacks, thereby improving the safety factor of the car. It can continuously monitor the vehicle for any faults and clearly display fault information on the trip computer screen. It helps in early detection of vehicle faults during the warranty period, allowing for timely resolution. It is an excellent companion tool.

How to reset the tire pressure on a Mercedes-Benz B200?

Mercedes-Benz B200 tire pressure reset method: First, turn on the ignition switch, press and hold the tire pressure monitoring reset button until you hear a "ding" sound, then release. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally, the dashboard warning light will turn off, completing the tire pressure reset. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: Usually, the system will alert if the pressure is below 1.8 bar or above 3.0 bar. At this point, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator to light up. Simply perform a tire pressure reset to resolve this. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, it can also cause the tire pressure warning light to turn on. For sensor damage issues, only replacement with a new part is the solution.
