Why Can't Court-seized Vehicles Undergo Annual Inspection?

What does it mean when the engine light on the dashboard is on?

Generally, when a malfunction indicator light is illuminated, it indicates that the component being monitored by the light has detected an abnormality. Below are some possible reasons why the engine light might be on: 1. The oxygen sensor detects the oxygen concentration in the exhaust gases and sends this information to the ECU in the form of an electrical signal. The ECU then uses this data to control the fuel injection amount. If the oxygen sensor is damaged, it will inevitably affect the air-fuel ratio of the mixture, thereby impacting the engine's normal operation. The air flow meter senses the intake air volume and relays this information to the ECU, which then controls the fuel injection accordingly. If the ECU cannot receive this information, the engine malfunction light will also illuminate. 2. If low-grade gasoline is used or the engine temperature becomes excessively high, it can lead to engine knocking. Engines are equipped with knock sensors, and when the sensor detects a tendency for knocking, the ECU will attempt to mitigate it by delaying the ignition timing. However, if the issue exceeds the ECU's capacity to handle, the engine malfunction light will turn on. 3. Solution: If the engine malfunction indicator light comes on, it is important to seek timely inspection and repair.

What to Do When the Car Battery Is Completely Dead?

If the battery is dead, you can call a friend to come over and give you a jump start. Jump starting requires jumper cables; if you don't have any, you can borrow them from a nearby auto repair shop. Here are some relevant details about car batteries: 1. The battery is a very important component of a car. When the engine is not running, the battery powers the vehicle's electronic devices and is also responsible for starting the engine. 2. When starting the engine, the starter needs to turn, the ignition system needs to spark, and the fuel system needs to build oil pressure—all of which require electricity. 3. If you don't drive for a long time, it is recommended to disconnect the negative terminal of the battery to prevent it from draining. If the car is left unused for an extended period, take it out for a short drive occasionally to allow the alternator to recharge the battery. 4. During winter nights, try to park the car in an underground parking lot or your own garage to protect the battery. The low outdoor temperatures in winter can reduce the battery's lifespan if the car is left outside overnight, and it may cause difficulty starting the engine the next morning.

Should an automatic transmission be shifted to P or N for temporary parking?

For temporary parking with an automatic transmission, first shift to N gear, then turn off the engine before shifting to P gear. Below is the correct operating sequence for parking an automatic transmission vehicle: 1. On flat ground, after pressing the brake pedal to bring the vehicle to a complete stop, shift to N gear, then engage the handbrake. Turn off the engine before shifting to P gear. 2. When parking on a slope, you must shift to N gear, firmly engage the handbrake, then release the brake before turning off the engine. If you shift to P gear before turning off the engine, the vehicle may easily roll backward. 3. When starting an automatic transmission vehicle, avoid stomping on the accelerator. It is also not advisable to use N gear for coasting, as this can damage the engine and transmission, causing varying degrees of wear. Additionally, a vehicle without power is in a passive state, compromising safety. 4. If the vehicle is parked on flat ground for an extended period without risk of rolling, you can use N gear for parking. This reduces the burden on the vehicle's mechanisms and extends the lifespan of the internal components of the parking system.

Can the EA211 spark plug use double platinum?

The Volkswagen EA211 engine can use double platinum spark plugs. Platinum spark plugs have a longer lifespan than ordinary spark plugs. Typically, the lifespan of a platinum spark plug is five times that of a standard spark plug, with double platinum spark plugs averaging a lifespan of up to 160,000 kilometers. The advantages of double platinum electrode spark plugs are as follows: 1. Improved engine ignition performance. 2. Enhanced spark plug firing performance. 3. Easier to maintain the engine within the optimal temperature range between self-cleaning combustion and incandescent combustion. 4. Expanded thermal range of the engine. 5. Excellent durability.

How to Solve Strong Jerking Sensation When Decelerating in Automatic Transmission?

Automatic transmission jerking is closely related to automatic gear shifting and the overall powertrain conditions, including engine speed, driving speed and resistance, throttle depth, etc. If the timing of gear shifting is not properly managed, a jerking sensation may occur. Solutions for automatic transmission jerking are as follows: 1. During rapid acceleration, the automatic transmission usually shifts between 2500 to 3000 RPM. 2. During gentle acceleration, the automatic transmission typically shifts between 1500 to 2200 RPM. 3. A trick to reduce gear-shifting jerking: "gradually press the accelerator, lightly lift the foot, and then press again." The gear-shifting timing for automatic transmissions is generally controlled within low RPM ranges, which can help minimize jerking. Below is an analysis of the causes of jerking during deceleration in automatic transmissions: 1. Since gear shifting is controlled by the computer, there may be a mismatch in the differential gear shifting, leading to jerking. 2. Dirty throttle body—cleaning the throttle body can resolve this issue. 3. Transmission problems—if there are issues with the transmission, jerking may also occur during deceleration.
