How many days can a new car go without temporary license plates?

Temporary license plates are generally valid for no more than thirty days, and new cars should not use temporary plates for more than 15 days. Here are some relevant precautions for using a new car: 1. Avoid overloading: Carrying too much weight in a new car during the break-in period can damage the mechanical components. Since the power transmission parts of a new car have not yet fully broken in, aggressive acceleration can cause irreversible damage to the vehicle. Therefore, during the break-in period, it is essential to follow the principle of "slow is better than fast." 2. Speed limits for new cars: Domestic cars generally have a speed limit of 40~70 km/h, while imported cars usually have a limit of 100 km/h. When the throttle is fully open, the speed should not exceed 80% of the maximum speed. The engine speed during the break-in period is recommended to be between 2000~4000 rpm.

What does the inspection record on the vehicle license mean?

The validity period of the inspection record on the vehicle license is the annual inspection date of the vehicle. The vehicle is considered valid before this date, and must be re-inspected after this date. Below is relevant information about the vehicle license: 1. Introduction to the vehicle license: The motor vehicle license is the legal document permitting the vehicle to drive on roads within China. The 'Motor Vehicle License' is an important document recognized by Chinese laws and regulations, playing a significant role. Motor vehicle drivers must pay great attention to it to protect their legal rights from being infringed. The 'Motor Vehicle License' in the driver's hand records many important details, including the license plate number, owner's name, model type, engine number and chassis number, load capacity or passenger capacity, initial registration date, and annual inspection records, etc. 2. Functions of the vehicle license: Proof of vehicle registration, proof of ownership, proof for insurance claims, and warranty certificate for new vehicles.

What does energy recovery in new energy vehicles mean?

Energy recovery refers to the process during vehicle braking where the motor is controlled to operate in a power generation state, converting the mechanical energy of the vehicle's movement into electrical energy, which is then stored in energy storage systems such as batteries, thereby recovering a portion of the braking energy. The following is relevant information about new energy: 1. Definition: New energy, also known as non-conventional energy, refers to various forms of energy other than traditional energy sources. It includes energy sources that are just beginning to be developed and utilized or are under active research and awaiting promotion, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy, and nuclear fusion energy. 2. Characteristics: Abundant resources, generally featuring renewable properties that can be sustainably utilized by humans. Low energy density, requiring significant space for development and utilization.

What is the issue when a car doesn't move after shifting gears?

When a car doesn't move after shifting gears, it is a comprehensive functional failure involving the clutch, transmission, and drive axle. Below are relevant explanations about car starting: 1. Reasons for difficult cold starts: Poor fuel quality often results in low volatility of inferior fuel, especially during winter when temperatures are low. During a cold start, the engine block temperature is low, making it difficult for the fuel to atomize. This leads to insufficient mixing of fuel and air in the cylinder, causing starting difficulties or even failure to start. The lower the temperature, the more fuel is required for a cold start, and the presence of carbon deposits will significantly affect whether the cold start proceeds smoothly. Carbon deposits in various parts of the engine negatively impact its normal operation. 2. Solutions: Replace the fuel pump, adjust the valve clearance, inspect and promptly replace the coolant temperature sensor, and replace the relay.

What is the reason when the car's accelerator is fully pressed but the RPM does not increase?

Factors that cause the car's RPM to not increase when the accelerator is pressed mainly include faults in the car's accelerator pedal, intake system, fuel system, ignition system, and ECU control components. Below is relevant information about the car's accelerator: 1. Function of the car's accelerator: In gasoline engines, the accelerator does not control the fuel injection volume but rather the throttle valve opening size. That is, a smaller opening results in less mixture entering the cylinder, leading to lower engine power output, and vice versa. 2. Solutions for a heavy accelerator pedal: A heavy accelerator pedal can be addressed by cleaning the fuel system. Alternatively, try continuing to accelerate to see if the RPM increases but the speed does not. If this occurs, it may be due to a damaged sensor inside the transmission, which locks the overdrive gear.

What is the fuel consumption of a sedan?

The fuel consumption of a sedan is 9 liters per 100 kilometers. Below is relevant information about fuel consumption: 1. Fuel consumption per 100 kilometers: This refers to the amount of fuel a vehicle consumes when driving a hundred kilometers at a certain speed on the road. It is a theoretical indicator for vehicles. Manufacturers determine this value by using a dynamometer installed on the vehicle's chassis in controlled environments, converting the measured data into speed parameters, and then calculating the theoretical experimental fuel consumption data per 100 kilometers for the model at specified speeds. 2. Road condition fuel consumption: Also known as multi-condition road cycle fuel consumption, this is a fuel indicator calculated based on repeated tests where the vehicle is driven on specified roads at regulated speeds and times. The standard specifies that each cycle includes various driving conditions, recording parameters such as gear shift timing, stopping time, driving speed, acceleration, braking, and deceleration for each cycle. The values obtained through this method are closer to real-world consumption.
