Is It Legal to Install an Auxiliary Fuel Tank on an Off-Road Vehicle?

Installing an auxiliary fuel tank on an off-road vehicle is an illegal act. Below are some relevant considerations regarding vehicle modifications: 1. Reasonable Upgrades: Reasonable tire upgrades can work in conjunction with the braking system to shorten the vehicle's braking distance and increase the adhesion coefficient to the road surface during high-speed driving. However, some owners blindly increase the size and width of tires and rims during upgrades, neglecting the data matching of the tires, which creates significant safety hazards for the vehicle. 2. Headlight Modifications: Upgrading to xenon headlights is currently a popular method to enhance headlight brightness. Replacing the front headlights with xenon lights is a safe modification in itself. When modifying headlights, it is advisable to adjust the low beams rather than the high beams. Additionally, vehicles with modified headlights must adhere to the regulation of switching from high beams to low beams when approaching an oncoming vehicle at about 100 meters during nighttime driving, ensuring that the visibility of other vehicles is not affected.

What are the penalties for a vehicle that has not undergone annual inspection for one year?

The penalty for a vehicle that has not undergone annual inspection for one year is: a deduction of 3 points and a fine of 200. Below are the relevant introductions about the annual inspection times for different types of vehicles: 1. Passenger vehicles: Operational passenger vehicles must be inspected once a year within 5 years, and once every 6 months after exceeding 5 years. 2. Cargo vehicles: Cargo vehicles and large and medium-sized non-operational passenger vehicles must be inspected once a year within 10 years, and once every 6 months after exceeding 10 years. 3. Non-operational vehicles: Small and micro non-operational passenger vehicles must be inspected once every 2 years within 6 years, once a year after exceeding 6 years, and once every 6 months after exceeding 15 years.

How to Calculate the Payload Utilization Coefficient?

The calculation method for the payload utilization coefficient is: the ratio of the vehicle's rated payload to its curb weight, i.e., rated payload/curb weight. Relevant information about the payload utilization coefficient is as follows: 1. Vehicle dry weight: The dry weight of a vehicle refers to the curb weight without coolant, fuel, oil, spare tire, tools, and accessories. Clearly, with the same payload, the smaller the dry weight, the higher the vehicle's mass utilization coefficient and its transportation efficiency. 2. Mass utilization coefficient: The mass utilization coefficient of the EQ1092F is approximately 1.22. With advancements in automotive material technology and manufacturing and design techniques, there is a trend of continuous improvement in the mass utilization coefficient of vehicles.

Is a Fuel Consumption of Over 20 Normal?

Fuel consumption of over 20 is not normal. Different car models, road conditions, and driving habits result in varying fuel consumption, which typically ranges between 6-10L per 100 kilometers. Below are the key factors influencing car fuel consumption: 1. Driving Habits: Aggressive driving, sudden acceleration, or abrupt braking can significantly impact fuel consumption. Statistics show that incorrect driving habits can increase fuel consumption by 5-30%. 2. Tire Pressure: Both overinflated and underinflated tires can lead to higher fuel consumption. 3. Road Conditions: Driving frequently on poor road conditions increases engine load, naturally raising fuel consumption.

Reasons for Battery Warning Light Illumination in Rainy Weather

Here are the reasons and solutions for the battery warning light illuminating in rainy weather: 1. Battery malfunction: Such as depleted battery charge or battery failure. Solution: Use a multimeter to test the battery voltage; recharge if the voltage is low, replace if the battery is faulty. 2. Battery terminal issues: Loose connections or oxidation leading to poor contact can also trigger the battery light. Solution: Clean and tighten the battery terminals. 3. Alternator malfunction: Faulty voltage regulator or excitation circuit issues causing abnormal operation may illuminate the battery light. Solution: Troubleshoot the alternator.

How Many Kilometers Can Original Tires Run?

Original tires can run for 80,000 kilometers. The following points should be noted regarding tire replacement: 1. Replacement time: It is recommended to replace tires every four years, even if the mileage is relatively low during these four years. Tires are rubber products, and rubber products will age over time. 2. Tire selection: When purchasing tires, be sure to check the specifications and model, as well as the production date, speed rating, and load index. Generally, the sidewalls of tires for family cars or SUVs are marked with 91V. After reinstalling tires, it is essential to perform dynamic balancing to prevent abnormal vibrations during high-speed driving.
