If the fuel pump is damaged and the engine won't start, the fuel pump must be replaced. The reasons for fuel pump damage are as follows: 1. Insufficient fuel in the tank: When the fuel level warning light on the dashboard lights up, there is approximately 7 liters of fuel remaining in the tank. At this point, the fuel level is too low, preventing the fuel pump motor from receiving adequate cooling and lubrication, which can cause the motor to overheat or even stop. 2. Poor fuel quality: When fuel quality is poor, the fuel tank may contain various impurities or foreign objects. The fuel is sucked in through the filter screen at the bottom of the pump and delivered to the engine. During this process, large particles are blocked by the filter screen, while small particles are sucked into the fuel pump motor, inevitably accelerating wear and tear and causing damage. 3. Long-term neglect of fuel filter replacement: If the fuel filter is not replaced for a long time, the fuel supply system can become severely clogged, making it difficult for the fuel pump to deliver fuel. Prolonged operation under high load conditions can lead to fuel pump damage.

Where is the rearview mirror heating switch of the Roewe i5?

The rearview mirror heating switch of the Roewe i5 is located below the central control screen, together with the front windshield defogging switch. The rearview mirror heating function refers to the heating of the electric heating wire embedded behind the lens of the mirror when driving in rainy, snowy, or foggy weather, ensuring the clarity of the mirror surface. The Roewe i5 is positioned as a compact car, featuring a rhythmic design language that gives it a more sporty appearance. The main characteristics of the rhythmic design language include: a through-type taillight, a full-balanced double-drive wind-shadow waistline, and a winged dynamic wide-body front face. In terms of configuration, the Roewe i5 is equipped with the SAIClink intelligent connectivity system.

What does a 72v electric vehicle charger mean?

Electric vehicle charger 72v refers to the voltage of the power battery being 72 volts, which means the voltage supplied to the motor is 72 volts. The following is a related introduction about electric vehicle batteries: 1. Two important indicators of the battery: The battery has two crucial indicators: voltage and capacity. The larger the battery's capacity, the longer the driving range of the electric vehicle will be. The higher the voltage of the power source, the faster the speed of the electric vehicle will be. 2. The importance of the battery to the electric vehicle: The battery used in electric vehicles is the only power source. Most electric vehicles use lead-acid batteries, which, comparatively speaking, have lower usage costs and relatively higher cost performance. Since this type of battery can be recharged, it can be used repeatedly.

What is the difference between multi-point injection and hybrid injection?

The difference between multi-point injection and hybrid injection is that hybrid injection engines are more advanced than multi-point fuel injection engines. Below are the specific differences: 1. Multi-point fuel injection engine: Engines using multi-point fuel injection supply fuel by injecting gasoline into the intake manifold. The injectors are installed in the intake pipe of each cylinder, and gasoline is injected from multiple locations (at least one injection point per cylinder) into the manifold, where it mixes with air. The engine's intake stroke then draws the air-fuel mixture into the cylinder. The biggest advantage of multi-point fuel injection engines is the more precise control of the air-fuel ratio. It allows for fuel injection based on timing, enabling precise control over the amount and timing of fuel injection. This reduces fuel consumption and meets stricter emission regulations. Currently, many vehicles on the market use multi-point fuel injection, which is the most mature fuel injection technology in use today. 2. Hybrid injection engine: Although both multi-point fuel injection and direct injection have their own advantages, they also have their respective drawbacks and limitations. Therefore, hybrid injection technology, which combines the two, has emerged. It consists of a fuel supply system that combines direct injection into the cylinder and manifold injection. In terms of operation, hybrid injection also combines the advantages of direct injection and manifold injection while mitigating their weaknesses. This not only improves efficiency but also avoids the emission issues caused by excess oxygen in direct injection engines under low-load conditions.

Can I Get a Refund If I Don't Want to Take the Driver's License Test Anymore?

Refunds are possible. The issue of driving school training fees is handled according to the contract. In principle, any fees that have not been incurred can be refunded. If you want to drop out during the driving course, it's allowed as long as you pay attention to the contract details when signing with the driving school. Additional information: 1. Issues with the driving school: After completing Subject 1, if you want to change driving schools due to problems with the current one. Since it's the driving school's fault, you can negotiate with them. If negotiations fail, you can contact other relevant authorities for mediation. 2. Personal reasons: After completing Subject 1, if you want to change driving schools for personal reasons. The difference between these two situations lies in whether the request to change schools is made before or after Subject 1. The solution is to negotiate with the driving school.

When is the best time to refuel a car's gas tank?

It is best to refuel when the car's gas tank is down to 1/4. Here are the specific reasons: 1. Helps the fuel pump dissipate heat: If there is too little fuel left in the tank, the fuel pump is often exposed to air, which can cause overheating. Driving like this for a long time may lead to burning or erosion of the fuel pump. Properly immersing the fuel pump in gasoline helps it dissipate heat quickly. 2. The amount of refueling should be determined based on the actual situation of the vehicle: The most suitable amount of fuel to add each time depends on the owner's circumstances. Generally, a single refueling should last the owner about 15 days. This is mainly because gasoline also has a shelf life, especially ethanol gasoline, which has strong water absorption. If the air humidity is too high and the gasoline contains moisture, it can easily cause problems after engine combustion.

What should beginners pay attention to when driving on the road?

New drivers need to pay the most attention to the transition in skills and mindset, followed by traffic common sense. Here are some relevant introductions for beginners on the road: 1. Skills and mindset: Skills require more practice—find a place with fewer people to practice more. The mindset needs to shift from the driving test (Subject Three) to actual road driving. Driving during Subject Three and driving after obtaining the license are two different things. During Subject Three practice, you drive a training car; other vehicles will actively give way when they see a training car. 2. Displaying a novice sign: However, after obtaining the license and driving a private car on the road, other drivers won’t be as courteous. At this time, it is necessary to display a novice sign in the appropriate position on the car to let others know you are a beginner, which is safer. 3. Following distance: Another important point is to understand the following distance. In Subject Three, the following distance is based on the test items; during practice, you follow a fixed sequence on a fixed route, and the actions of the vehicle ahead are predictable. Actual driving is different because you don’t know what the car in front will do next. Many drivers in China don’t like to use turn signals and often brake suddenly, which can easily lead to accidents if the following driver lacks experience.
