Does the Baojun 730 require fuel tank removal to replace the fuel pump?

Replacing the fuel pump in a Baojun 730 requires fuel tank removal. As the most fundamental component in the engine's fuel supply system, the fuel pump is responsible for extracting fuel from the tank during engine operation. It continuously delivers fuel at a certain pressure through the supply lines to the engine, where the high-pressure fuel pump performs secondary pressurization, providing measured amounts of fuel to each cylinder according to the engine's firing sequence. Function of the fuel pump: Gasoline serves to cool and lubricate the fuel pump. Failure to refuel promptly after the fuel warning light comes on can reduce the cooling and lubrication effects, potentially causing damage. Impact of fuel quality on the fuel pump: Impurities in low-quality gasoline can lead to blockages in the fuel supply system and cause wear and damage to the fuel pump. Early failure of fuel pumps is mostly attributed to the use of substandard fuel in vehicles. Electric fuel pump: Electric fuel pumps, unlike those driven by camshafts, operate by electromagnetic force repeatedly actuating the pump diaphragm. These electric pumps offer flexible installation options and can prevent vapor lock phenomena.

Last time I went to repair the fuel pump of my Baojun 730, I found that the fuel tank indeed needed to be removed because the fuel pump is inside the tank and can't be accessed without taking it out. The steps involve first draining the gasoline to avoid leakage risks, then lifting the car body to disconnect the fuel lines and wiring. Only after the entire fuel tank is removed can the new fuel pump be replaced. The process is quite labor-intensive, so it's recommended to have a professional mechanic handle it—gasoline is flammable, and any accidental sparks could be disastrous. If your car has issues like poor acceleration or stalling, getting it checked early can prevent bigger problems—don't delay repairs to save trouble. After replacement, remember to test the fuel system's sealing to ensure safe driving.

Do I need to register for changing from 17-inch to 18-inch wheels?

Changing from 17-inch to 18-inch wheels does not require registration and can be used normally. Here is some related information: 1. Upgrade the ignition system: Properly upgrading the ignition system can enhance the vehicle's performance. The modification of the ignition system includes spark plugs, spark energy, and ignition wires. The ignition wires connecting the ignition system and spark plugs are currently one of the most popular modification projects. The benefit of modifying this component is to reduce electromagnetic interference while improving resistance, minimizing the loss of high-voltage current sent from the high-voltage coil to the spark plug, thereby enhancing performance. 2. Install a body kit: Body kits originated from motorsports and primarily reduce the reverse airflow generated during driving while increasing downforce, making the vehicle more stable. Body kits are the most prominent accessories for personalizing the appearance, so many owners install them for aesthetic purposes.

Can motor vehicles use non-motorized vehicle lanes?

Motor vehicles are not allowed to use non-motorized vehicle lanes. Here are the precautions for motor vehicles on the road: 1. Do not exceed the speed limit: When driving on the road, motor vehicles must not exceed the maximum speed indicated by speed limit signs. On road sections without speed limit signs, safe speeds should be maintained. When driving at night, on dangerous road sections, or under weather conditions such as sandstorms, hail, rain, snow, fog, or icy roads, driving speed should be reduced. 2. Drive in the designated lane: When encountering vehicles ahead that are stopped in a queue or moving slowly, motor vehicles must not overtake by using other lanes or occupy the opposite lane, nor should they cut into the queue of waiting vehicles. In sections or intersections where lanes are reduced, or at intersections without traffic lights, signs, markings, or police direction, motor vehicles should take turns to proceed in an orderly manner when encountering stopped or slow-moving queues.

How Long Does the Theory Class for Subject One Last?

Subject One theory learning requires 12 class hours before taking the exam. The maximum daily training for theory learning is 4 hours; if the learning time exceeds 4 hours, it will be counted as 4 hours. The total time for the Subject One exam is 45 minutes, and the test paper consists of 100 questions, including true/false and multiple-choice questions, with a full score of 100 and a passing score of 90. The test paper is randomly selected and combined by the computer driver examination system according to the proportion specified in the "Motor Vehicle Driver's License Work Regulations". Below is the distribution of class hours for the C1 driving test: 1. Subject One: 12h of theory. 2. Subject Two: 2h of theory, 32h of practical training, totaling 34h. 3. Subject Three: 12h of theory, 24h of practical training, totaling 36h.

Do Sedans Have Lightning Protection Devices?

Sedans do not have lightning protection devices. The tires of a car have good insulation properties. If lightning strikes the car and electrifies it, the current cannot form a circuit as it cannot reach the ground, thus posing no harm to people or the vehicle. Precautions for driving in rainy weather: 1. Maintain a sufficient safe distance. Drivers should appropriately reduce speed, increase the following distance, and turn on the headlights, especially when driving in heavy rain. 2. Avoid accelerating to overtake. When driving in the rain, always pay attention to the speed and direction of the vehicle in front. Never accelerate to overtake just because the vehicle ahead is moving slowly. On highways, where the speed of vehicles in each lane is relatively high, the driver's field of vision narrows, and the road surface is slippery. Forcing a lane change to overtake can easily cause the wheels to skid with just a slight turn of the steering wheel, leading to accidents such as vehicle rollovers. 3. Prevent tire skidding. The ground is slippery in the rain, making tire skidding more likely. Avoid sudden braking when turning; it's best to decelerate in a straight line before entering the curve.

What type of driver's license is required to drive a 15-seater vehicle?

To drive a 15-seater vehicle, the driver must possess a B1, A1, or A2 license. Below is relevant information: 1. Requirements for upgrading to a B1 license: The applicant must have held a (C1) license for at least three years, be aged between 21-50 years old, and have no record of accumulating 12 penalty points in both the current and previous annual scoring cycles. Applications for upgrading to a (B1) license must be submitted to the local vehicle management office in the driver's registered residence, as regulations stipulate that such upgrades can only be processed at the driver's permanent residence location, not temporary residences. 2. Age requirements: Applicants for small cars, small automatic transmission vehicles, small automatic transmission vehicles for disabled persons, and light motorcycles must be between 18 and 70 years old.

What Are the Types of Gasoline at Gas Stations?

Gasoline is categorized into leaded gasoline, unleaded gasoline, and another type called ethanol gasoline. Common gasoline grades include 89, 92, 95, and 98. The differences between these types of gasoline are as follows: 1. Different Octane Ratings: 89 gasoline contains 89% isooctane; 92 gasoline contains 92% isooctane; 95 gasoline contains 95% isooctane; and 98 gasoline contains 98% isooctane. 2. Different Anti-Knock Properties: The higher the gasoline grade, the higher the isooctane content, resulting in stronger anti-knock performance. 3. Different Applicable Compression Ratios: Different gasoline grades have varying compression ratio requirements. The higher the engine's compression ratio, the higher the required gasoline grade. Generally, engines with a compression ratio greater than 8.0 should use 92 gasoline; those with a compression ratio greater than 9.0 should use 95 gasoline; and engines with a compression ratio greater than 10.0 should use 98 gasoline. 4. Different Applicable Models: 92 gasoline is suitable for ordinary cars with low technical specifications, 95 gasoline is suitable for most cars, and 98 gasoline is suitable for luxury cars and sports cars.
