How to Check if a Vehicle Meets China 5 or China 6 Emission Standards?

To determine whether a vehicle meets China 5 or China 6 emission standards, you can check the vehicle's factory certificate or the environmental compliance list. For used cars, you can query the vehicle's model number on the environmental protection website. Below is relevant information about China 5 and China 6 standards: 1. China 5 Overview: The China 5 standard, officially known as the National Fifth Stage Emission Standard for Motor Vehicle Pollutants, is equivalent to the Euro 5 emission standards implemented in Europe. The European Union has enforced these standards since 2009, imposing stricter limits on nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter emitted by vehicles. 2. China 6 Overview: The National Sixth Stage Emission Standard for Motor Vehicle Pollutants was established to implement the Environmental Protection Law of the People's Republic of China and the Air Pollution Prevention and Control Law of the People's Republic of China. It aims to prevent pollution from exhaust emissions of compression-ignition and gas-fueled ignition engines, protect the ecological environment, and safeguard human health.

Can a car still run if it has no engine oil at all?

If there's no engine oil left, meaning the dipstick shows no oil but the oil warning light hasn't come on yet, you can still drive. However, if the oil warning light is on and the engine noise becomes louder, it's recommended not to drive. Information about engine oil: 1. Oil change: Once engine oil is unpacked and added to the engine, whether the engine is running or not, after a period of time, oxygen in the air will react chemically with the additives in the oil, weakening or eliminating the protective effect of the oil. Therefore, after a certain period, the oil must be changed. 2. Shortening the cycle: In actual use, adjustments should be made based on specific usage conditions. For example, if you frequently drive at low speeds in congested urban intersections, take frequent short trips, drive in low temperatures, or if the local fuel quality is poor, it's advisable to appropriately shorten the oil change cycle. If you often drive under good road conditions with the engine mostly operating at economical speeds, you can appropriately extend the oil change cycle.

What is the minimum voltage at the moment of ignition start?

The minimum voltage at the moment of ignition start is approximately 10.8V. Regarding car batteries, the charging voltage typically should not exceed 14.4V. The lower limit of voltage during ignition start is around 10.8V, while the voltage during startup is about 11.8V, and the voltage after startup is around 14V. When the battery voltage drops below 10V, it indicates severe battery depletion, and the car usually cannot be started, requiring a recharge. Below is an introduction to car batteries: 1. Function of the battery: The battery, also known as a storage battery, provides electrical energy for starting the car and adjusts the imbalance between the generator's output and the load. (1) When the engine is running, the generator primarily supplies power to various electrical devices. If the generator produces excess electricity, the surplus is stored by charging the battery. When the engine starts or the generator's output voltage is too low to power the electrical devices, the battery supplies the power. (2) When the engine is not running, the battery powers the electrical devices. If the power demand of the electrical devices exceeds the generator's output, the battery and generator work together to supply power. If the power demand is less than the generator's output, the generator powers both the battery and the electrical devices. If the generator fails, the battery can provide emergency power, ensuring the car's electrical devices can operate for a short time. 2. Battery maintenance: Modern maintenance-free batteries often use alloy grids, enhancing corrosion resistance and tensile strength. The lost electrolyte during charging can quickly flow back, eliminating the need for liquid replenishment. Maintenance-free batteries typically have strong overcharge resistance, long energy storage duration, and can provide stable high-current output. When using maintenance-free batteries, note that if they are excessively discharged and not recharged promptly, their lifespan will be shortened. Therefore, for cars parked for extended periods, it is advisable to start the car every 25 days or so and let it idle for about 10 minutes. Otherwise, prolonged parking may lead to excessive discharge, making the car unable to start. Additionally, in winter, if the car has difficulty starting and repeated ignition attempts are made, it can cause excessive battery discharge and damage.

What Causes the Clicking Sound When Braking?

The reasons for the clicking sound when braking are as follows: 1. Normal ABS Activation: The ABS working process is actually a cyclic process of locking-releasing-locking-releasing, keeping the vehicle in a state of critical lock intermittent rolling. When you brake hard and trigger the ABS, it will produce a clicking sound, which is a normal phenomenon. In this case, just press the brake pedal firmly to the floor. 2. Gear Shift Sound in Automatic Transmission Vehicles When Braking: If you hear a "click" sound from the transmission and gear lever when pressing the brake pedal, the main reason for this sound may be the electronic linkage between the brake system and the automatic transmission. Pressing the brake activates the transmission solenoid valve, producing a "click" sound. At this time, you need to press the gear lever lock button to shift gears, which serves as a safety reminder. 3. Actual Malfunction: If the clicking sound occurs even with light braking, or if the vehicle does not have an automatic transmission lock button, or if the sound is continuous or occurs intermittently, then you should pay attention. It is highly likely that there is a fault in the brake system or a loose connection in some part of the chassis. For safety reasons, the owner should take the vehicle to a 4S shop for inspection as soon as possible.

How to Prevent Window Fogging When Using Heater in Winter?

When using the car heater in winter, press the defogging button to direct the warm air towards the windshield. Open the side windows slightly to allow air convection inside the car. As the interior temperature gradually approaches the outside temperature, window fogging will be prevented. The causes of window fogging are as follows: 1. Difference in temperature and humidity between inside and outside the car: In winter, fogging occurs on the inside of the windows because the outside temperature is low while the interior is warm due to the heater, causing condensation. Water vapor condenses into tiny droplets on the cold glass, forming fog. In summer, the opposite occurs with fog forming on the outside of the windows. Many people use cold air to defog in winter. 2. Significant temperature difference between indoor and outdoor environments: Generally, the front windshield defrosting function can be used based on driving conditions. If the car is equipped with automatic air conditioning and allows selection of air outlet positions, it is recommended to choose the front windshield and central air outlets, and turn on the rear windshield heating function. This way, the temperature inside the car is constantly regulated, preventing fogging. 3. Avoid selecting two air outlet directions simultaneously: Activate the front windshield defrosting and rear windshield heating functions. If the side windows fog up, slightly opening them can quickly remove the fog. After closing the windows, fog will not reappear once the interior temperature rises.
