How to Check the Tire Pressure Monitoring System on Volkswagen Lavida?

What is the difference between direct injection and multi-point fuel injection?

Multi-point fuel injection electronically controls the injection of fuel into the intake manifold to mix with air, and the engine's intake stroke then draws the air-fuel mixture into the cylinder. Direct injection, on the other hand, moves the fuel injector from the intake manifold to inside the cylinder, so the amount of air-fuel mixture is not affected by the opening and closing of the intake valve but is directly determined by the computer for timing and quantity. The differences between multi-point fuel injection and direct injection are as follows: 1. Fuel quality: Direct injection has higher fuel quality requirements compared to multi-point fuel injection, with a compression ratio as high as 12. 2. Cost: Due to the more complex components of direct injection compared to multi-point fuel injection, the price is usually higher. In other words, for the same car, direct injection technology is more expensive than multi-point fuel injection technology. 3. Fuel consumption: Direct injection has significantly lower fuel consumption compared to multi-point fuel injection. 4. Power performance: Direct injection improves power and torque by 10% compared to a general engine of the same displacement. 5. Technical level: Multi-point fuel injection technology is more mature, while direct injection is a newer and more advanced fuel injection technology. 6. Maintenance: Multi-point fuel injection has a simpler structure, making it better in terms of maintenance, reliability, and upkeep compared to direct injection.

How to Turn Off the Engine Auto Start-Stop?

Engine auto start-stop can be turned off by following these steps: 1. Press the auto start-stop button directly (a circular arrow containing the letter A), and the dashboard will indicate that the system is turned off. 2. If you want to use this function again, press the button to turn it back on. 3. When auto start-stop is activated, pressing the brake pedal slightly harder will shut off the engine, and releasing the brake will restart the engine, thereby saving fuel. Below are some drawbacks of auto start-stop: 1. Higher maintenance costs for the battery and starter: Frequent engine starts and stops can damage related components, such as the starter and battery. Although vehicles equipped with auto start-stop systems use reinforced starters and batteries, in practice, their failure rates are higher than those in regular vehicles without this system. 2. Poor user experience: Different models from various brands have different designs for the auto start-stop system. Some models have suboptimal start-stop logic, with inaccurate timing for activation, and sometimes the system fails to engage during prolonged stops. 3. Increased fuel consumption in traffic jams: If stuck in heavy traffic, the engine may remain off for extended periods, causing the combustion chamber temperature to drop. Unburned hydrocarbons and paraffin can form carbon deposits on the cylinder walls. Poor fuel quality can worsen this issue. Carbon deposits lead to higher fuel consumption and reduced engine power, counteracting the fuel-saving purpose of the auto start-stop feature and potentially increasing fuel consumption instead.

What are the issues after modifying the GL8?

GL8 is a business vehicle under the Buick brand. The following are the issues that may arise after modifying the GL8: 1. Abnormal noises while driving, which are mainly caused by the following situations. (1) The middle aviation seats have factory defects, with poor stitching causing the seats to rub back and forth. Additionally, if the screws fixing the aviation seats are not tightened properly, the seats will wobble while driving. (2) The welcome footboard and wooden floor are not perfectly fitted, or the screws fixing the welcome footboard are too long and come into contact with the car body, which can also cause noises while driving. (3) Carelessness of the construction workers, leaving objects under the decorative panels or wooden floor, can also result in abnormal noises. (4) Unprofessional installation of the overhead nine-grid lights, without using sponge or foam padding at the fixing points, causing them to wobble and hit the roof beams. (5) The small table board on the back of the seat is not firmly fixed to the original car seat, which can also cause abnormal noises. 2. Instrument failures, airbag light on, and occasional failure to start the car. (1) Instrument failures and the airbag light being on may be due to the modification workers not reconnecting the plugs or loose plugs when restoring the seats. This situation is rare; generally, pressing the main and co-driver seats will turn off the airbag light. (2) If the car fails to start, check the induction module under the middle row. If there is a wooden floor, it should be taken out and placed under the seat, as the wooden floor can block the signal, preventing the key from sensing the car body. Another point is that if the plug behind the air conditioning controller on the middle row is not connected, the car will also fail to start.

Where is the manufacturer of Chaoyang brand tires located?

The manufacturer of Chaoyang brand tires is located in the New District of Wuxi City, Jiangsu Province. Tires are circular elastic rubber products installed on various vehicles or machinery to roll on the ground, typically mounted on metal rims. They support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain the vehicle's driving performance. Precautions for tire use include: 1. Worn tire treads can lead to loss of grip, increased risk of blowouts, and loss of dirt and water drainage functions; 2. Regularly check tire pressure; 3. Remove foreign objects from tires to prevent punctures that could cause air leaks or blowouts; 4. Rotate tire positions every 10,000 kilometers to evenly distribute tire fatigue, prevent uneven wear, and extend tire lifespan.

How to correctly start an automatic transmission car?

The correct steps to start an automatic transmission car are: 1. Depress the clutch, wait 5 to 8 seconds when turning the ignition key to the ON position; 2. Then turn the key to the start position to start the engine; 3. Immediately release the ignition key after the engine starts smoothly, allowing it to automatically return to the ON position. Automatic transmission means the driver does not need to manually shift gears, as the vehicle will automatically select the appropriate gear based on driving speed and traffic conditions. The gears of an automatic transmission are: 1. P gear is the parking gear; 2. R gear is the reverse gear; 3. N gear is the neutral gear; 4. D gear is the drive gear; 5. S gear is the sport mode; 6. L gear is the low-speed gear.

Does High Temperature Inside the Car in Summer Affect the Vehicle?

High temperature inside the car in summer does affect the vehicle. Here are the specific impacts: 1. Affects engine air intake capacity: Leads to a decrease in the engine's air intake coefficient. The higher the temperature, the lower the air density, resulting in reduced actual air intake by the engine; Due to engine overheating, the temperature under the hood increases further, reducing the engine's air intake capacity. 2. High temperatures can cause abnormal engine combustion: High atmospheric temperature increases the temperature of the air-fuel mixture entering the cylinders, raising the temperature throughout the engine's working cycle. Coupled with the lower heat dissipation efficiency of the radiator, the engine becomes overheated. The end-gas mixture in the combustion chamber absorbs more heat, intensifying pre-flame reactions, which increases the likelihood of engine knocking.
