The common problems with the B12 engine include: 1. Unstable idle speed, fluctuating between high and low; 2. Lack of power during acceleration. The car engine is the device that provides power to the vehicle, acting as the heart of the car, determining its power, fuel efficiency, stability, and environmental performance. Depending on the power source, car engines can be classified into diesel engines, gasoline engines, electric motors for electric vehicles, and hybrid systems. Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines, converting the chemical energy of fuel into the mechanical energy of piston movement to deliver power. Gasoline engines are characterized by high rotational speed, low weight, low noise, and easy starting; diesel engines feature high compression ratios, superior thermal efficiency, excellent fuel economy, and emission performance.

Is Newspaper Publication Required for Reporting a Lost Driver's License?

No newspaper publication is required for reporting a lost driver's license. The relevant information for a lost driver's license is as follows: Provide proof: the identity proof of the motor vehicle driver; a written statement declaring the loss of the motor vehicle driver's license. Reissue time: the vehicle management office that meets the requirements should reissue the motor vehicle driver's license within one day; after the motor vehicle driver receives the reissued driver's license, the original driver's license becomes invalid and must not be used anymore; during the period when the motor vehicle driver's license is legally seized, detained, or temporarily suspended, the motor vehicle driver cannot apply for a reissue. Application location: if the motor vehicle driver's license is lost, the motor vehicle driver should apply for a reissue at the vehicle management office where the driver's license was originally issued or at a vehicle management office outside the original issuing location.

How long can a car sit without the battery dying?

If your car's battery is relatively old, it may die after just two weeks of inactivity. If the battery is brand new, it could last about a month without use before losing charge. If you don't plan to use the car for an extended period, it's recommended to disconnect the negative terminal of the battery to prevent it from discharging. Battery function: The battery is a crucial component in a car. Without it, the vehicle cannot operate normally. When the engine is off, the battery powers all electronic devices in the car and is also responsible for starting the engine. During engine startup, components like the starter motor, fuel supply system, and ignition system all require electricity. If the battery is dead, the engine won't start properly. After starting, the engine drives the alternator, which then powers the car's electronic devices and recharges the battery. The battery is a wearable part that requires regular replacement, as its performance gradually declines with each charge-discharge cycle.

Does a car need inspection after bottoming out?

Car bottoming out requires inspection. The hazards of car bottoming out are as follows: Exhaust pipe rupture: The exhaust pipe is very fragile and located at the bottom of the vehicle. Hitting hard rocks or sharp objects can cause it to crack or even tear. The height and shape of obstacles vary, with some being higher or wider. Additionally, some drivers have the habit of not slowing down when crossing speed bumps, which can easily lead to exhaust pipe rupture. Control arm deformation: A car's tires are constrained by five angles in space, which affect steering control and torque transmission. When a car bottoms out, the control arm is highly likely to deform, significantly impacting the precise tire alignment parameters. This has an extremely negative effect on handling safety during high-speed turns. Therefore, it is best to go to a professional institution for four-wheel alignment parameter repairs after a bottoming out incident.

Can You Keep the Clutch Pedal Depressed During the Pull-Over Parking in Subject Three?

During the pull-over parking in Subject Three, you should not keep the clutch pedal depressed all the time. You need to fully depress the clutch and brake after completing all the steps. Precautions for pull-over parking: After receiving the pull-over parking instruction, apply the brake to decelerate, downshift, and observe the rear vehicles to avoid affecting the normal driving of other vehicles. After slowing down, turn on the right turn signal. After the turn signal has been on for 3 seconds, observe the rear vehicles to the right and turn the steering wheel to the right. Note: The turn signal must be fully engaged, and if it bounces back, quickly flip it back up. After turning on the turn signal, steer to the right and observe the highest point of the wiper aligning with the right edge line, or check if one-third of the front of the car aligns with the right edge line. At this point, the wheels should be 30 centimeters away from the road edge line. During the pull-over, control the clutch properly and move forward slowly. The speed should not be too fast to avoid delayed steering operations that may cause the wheels to cross the line. Observe if the car body is straight; if not, make timely minor adjustments without excessive movements. Once the 30-centimeter alignment with the edge line is achieved, fully depress the clutch and brake to stop, shift to neutral, engage the handbrake, turn off the right turn signal, and shut off the engine. After completing the parking procedure, ensure not to miss a crucial step: turn around to observe the traffic behind the car, confirm safety, unbuckle the seatbelt, and exit the car while closing the door.
