Differences between DC ignition and AC ignition: 1. Power supply method: AC ignition is powered by the stator coil of the magneto, while DC ignition is powered by the battery or rectifier. By checking whether the power supply line to the ignition comes from the magneto or the battery, you can determine whether it is an AC or DC ignition. 2. Shutdown method: AC ignition shuts down by short-circuiting the ignition signal line to ground. The ignition has a shutdown wire connected to the shutdown switch; closing the shutdown switch grounds the circuit to shut it down. In contrast, DC ignition shuts down by cutting off the DC power supply, achieved by turning off the shutdown switch. 3. Input voltage: DC ignition performs better in cold starts, while both types perform similarly in hot starts. 4. Ignition voltage: DC ignition provides stronger ignition energy and faster performance acceleration compared to AC ignition. 5. Fuel efficiency: DC ignition has higher ignition energy and significantly better acceleration performance than AC ignition, making it more fuel-efficient.

What is the function of the nuts provided with the license plate?

The function of the nuts provided with the license plate is to secure the license plate in place.

How Often Should Automatic Transmission Fluid Be Changed?

The replacement interval for transmission fluid varies depending on driving conditions. Generally, an automatic transmission vehicle under normal use requires a fluid change approximately every 50,000 kilometers. If the vehicle is frequently used and operates in harsh environments, the fluid should be changed every two years or so. For every 15,000 kilometers driven, the automatic transmission should be inspected and maintained. Check for any leaks, the level of the fluid, and the quality of the fluid. Any leaks must be repaired promptly. If the fluid level is low, it must be topped up with the same type of transmission fluid, being careful not to overfill, as excessive fluid can also cause significant damage to the transmission. According to the vehicle manufacturer's guidelines, the transmission fluid should be changed every two years or every 60,000 kilometers. If the vehicle has been used for over two years but has only been driven 20,000 kilometers, or if the vehicle has been used for less than a year but has already reached 60,000 kilometers, the transmission fluid should be changed in both cases. When changing the fluid, the filter inside the transmission pan should also be replaced, and only specialized transmission fluid should be used.

Are there vehicle checks on highways?

There are no traffic police conducting vehicle checks on highways. Below is an introduction to the relevant content: 1. Regulations: According to the "Road Traffic Safety Law," there are strict regulations regarding traffic police enforcement on highways. Except for executing emergency duties, they are not allowed to intercept and inspect vehicles on highways. 2. Danger: It is too dangerous for traffic police to check vehicles on highways due to the high speed of vehicles. Drivers often cannot brake in time when they see traffic police, and sudden braking may cause traffic accidents. Below is extended information on the relevant content: 1. Emergency duties: Emergency duties have specific meanings and cannot be equated with general traffic violations on highways. There are many ways to correct violations, and it is not necessary to forcibly intercept vehicles. 2. Safety precautions: If vehicles must be intercepted and inspected on highways due to "emergency duties," checkpoints should be set up at toll booths, ramp entrances, etc., with prominent temporary inspection signs set up in advance to inform drivers ahead to slow down.

Was Lamborghini originally a tractor manufacturer?

Lamborghini was originally a tractor manufacturer. Here is some relevant information about Lamborghini: 1. Introduction: Ferruccio Lamborghini, the founder of Lamborghini, was a mechanic in the Italian Royal Air Force when he was young. Due to his work, Ferruccio was very familiar with mechanical principles. After World War II, a large amount of military supplies were abandoned. Ferruccio Lamborghini began using these surplus military materials to manufacture tractors and established the original Lamborghini company. 2. Origin: While driving a Ferrari 250GT, Ferruccio complained that the Ferrari's clutch malfunction caused the racing car to lose control, accidentally injuring spectators. However, Enzo Ferrari not only ignored the complaint but also told Ferruccio Lamborghini that he was incapable of driving a Ferrari 250GT and was only fit for driving agricultural machinery vehicles. Later, Ferruccio Lamborghini found a suitable spare part in his company's warehouse and installed it, solving the problem with the Ferrari 250GT. This incident fueled his passion for sports cars, leading to the creation of Lamborghini.
