EFI motorcycle won't start due to: 1. Anti-theft system lock; 2. Damaged fuel pump in the fuel supply system; 3. Faulty fuel injector. Troubleshooting methods: 1. If there's no sound of fuel pump operation when turning the key, check whether the EFI system fuse is blown and whether the fuel pump relay is damaged, replace the fuse or relay if necessary; 2. If there is sound of operation, remove the fuel injector, press the start button, and observe whether the fuel injection is properly atomized, replace the fuel injector if necessary. EFI motorcycle is a new type of motorcycle that uses a microcomputer to control the fuel injector to supply fuel to the working cylinders based on engine load, while non-working cylinders receive no fuel.

What documents should I bring when driving out?

When driving out, you should bring the following documents: 1. Driver's license: The permitted vehicle types on the license must match the vehicle you are driving. 2. Vehicle registration certificate: Carry the registration certificate that corresponds to the license plate of the vehicle you are driving. The registration certificate must not be lent, altered, or forged. 3. The driver's ID card. 4. License plate (or temporary plate or replacement plate certificate): The license plate should be properly and visibly displayed with clear characters, matching the vehicle type and number on the registration certificate. Expired or invalid temporary plates must not be used. 5. Road maintenance fee certificate: Carry a valid unified road maintenance fee payment certificate, ensuring the vehicle type, license plate, unit, and date on the certificate are correct. 6. Insured vehicles must carry the insurance policy. 7. If driving a commercial vehicle, you also need to carry the road transport practitioner qualification certificate.

What is the normal pressure of car air conditioning refrigerant?

Under the condition of compressor speed at 1500~2000 rpm, the normal pressure of car air conditioning refrigerant is approximately 1.5~2.0 MPa for high pressure (discharge pressure) and 0.15~0.35 MPa for low pressure (suction pressure). Extended information is as follows: 1. Introduction to normal car air conditioning pressure: Normal high pressure should be 1.3-1.7 MPa (13-17 kg/cm2 or 190-250 Lbf/in2); normal low pressure should be between 0.15-0.25 MPa (1.5-2.5 kg/cm2 or 20-35 Lbf/in2). 2. Introduction to normal car air conditioning pressure at idle: At idle speed, if the ambient temperature is high, such as under direct sunlight in summer, the high pressure may be slightly higher, up to about 2.5~2.8 MPa, but generally it will not exceed 3.1 MPa, otherwise the pressure switch will be protected. If the low pressure is higher or lower than this range, it indicates that the expansion valve adjustment is abnormal. If the compressor has problems, it is not within this category.

What brand is Kinergy-EX tire?

Kinergy EX is a passenger car tire developed by Hankook Tire from South Korea, specifically designed for European style. It is a tire that balances both dry and wet performance, with a focus on comfort. Hankook Tire was established in 1941 as a Korean tire manufacturer, providing radial tires for passenger cars, light trucks (SUVs, RVs, etc.), trucks, buses, and specialized racing vehicles. Hankook operates five R&D centers worldwide to ensure its tires meet regional consumer demands and enhance satisfaction. Hankook Tire products are available in over 180 countries and regions, entering the Chinese market in 1996. Kinergy EX has only one model, the H308. In terms of tread design, the H308 features optimized shoulder design to reduce noise during driving, variable groove widths to improve drainage and wet-surface performance, and silica-infused tread to lower rolling resistance and enhance fuel efficiency. As an all-season tire, Kinergy EX utilizes Hankook's Kontrol Technology. The functions of Kontrol Technology include: Enhancing tire performance and durability while maintaining excellent handling even in harsh conditions. Ensuring the vehicle maintains performance across various aspects during driving, especially under adverse weather and road conditions.

What Are the Hazards of Speeding?

The hazards of speeding include: affecting the safety performance of the vehicle; impacting the driver's ability to operate the vehicle promptly and accurately; causing errors in the driver's judgment; making it difficult to shift attention; reducing the driver's ability to judge speed; and weakening the driver's spatial awareness. Below is a detailed introduction to the hazards of speeding: 1. Speeding affects the safety performance of the vehicle: Speeding disrupts the vehicle's performance indices under specific working conditions, increases the vehicle's workload and stress, and accelerates wear and damage to components. This is particularly detrimental to the tires, leading to jumping and skidding wear, raising friction temperatures, and making the tires prone to aging and deformation, which can cause blowouts. 2. Speeding affects the driver's ability to operate the vehicle promptly and accurately: Prolonged speeding alters the driver's response to weak stimuli, causing reactions to stimuli that should not provoke a response and delaying reactions to stimuli that should. 3. Speeding can sometimes cause errors in the driver's judgment: When making decisions, drivers rely not only on perceived information but also on experience, analysis, and judgment. In the event of an emergency while speeding, even decisive action requires time for consideration. 4. Speeding makes it difficult to shift attention: When speeding, the driver must focus on the road ahead, constantly overtaking and meeting other vehicles. Each overtaking or meeting requires shifting attention from outside the vehicle (operating brakes, clutch, steering, acceleration) to checking instruments. Within these brief seconds, frequent shifts in attention can lead to fatigue and accidents. 5. Speeding reduces the driver's ability to judge speed: At high speeds, drivers not only misjudge their own vehicle's speed but also underestimate the speed of pedestrians, non-motorized vehicles, and other motor vehicles. This can lead to underestimating the speed and distance of oncoming vehicles when overtaking, as well as the required distance to overtake safely, often resulting in delayed reactions and collisions or scrapes. 6. Speeding weakens the driver's spatial awareness: The faster the speed, the farther the focus point. At speeds above 50 km/h, the focus point is often 305-601 meters ahead. As the focus point moves forward, the field of vision narrows, clarity deteriorates, and small or slowly changing objects become difficult to recognize, leaving little time to react when they are noticed.

Should You Press the Clutch or Brake When Going Downhill?

When going downhill, you should press the brake and shift to a lower gear, avoiding prolonged clutch engagement. For manual transmission vehicles, it is not advisable to shift into neutral or hold the clutch while descending. Instead, lightly apply the brake to control the speed. Below are the reasons for lightly applying the brake when going downhill: 1. When coasting in neutral, relying solely on the foot brake can cause the front brake discs to overheat, significantly reducing their effectiveness. Additionally, if the speed is too high, coasting in neutral makes it difficult to control the vehicle's speed, increasing the risk when descending. However, harsh braking downhill can also cause the engine to stall if the speed drops too low. The correct approach is to use a lower gear to descend, leveraging the engine's braking force for more stable control of the vehicle and speed, with light braking as an aid. 2. Avoid pressing the clutch unnecessarily when not shifting gears, as this driving habit can damage the vehicle. Generally, when descending, the recommended method is to first reduce speed (by braking) and then downshift (by pressing the clutch and shifting gears), only engaging the clutch to downshift after the speed has decreased.
