What is the standard designation for China 6?

What is the equivalent of China's National IV emission standard?

China's National IV emission standard corresponds to the fourth stage of national vehicle pollutant emission standards. The primary pollutants from vehicle emissions include hydrocarbons, nitrogen oxides, carbon monoxide, and particulate matter. This standard requires controlling and reducing these pollutants below specified limits through technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices. The National IV standard is equivalent to Europe's Euro IV standard. Compared to the National III standard, it imposes stricter controls on vehicle emissions, requiring a further 30% to 50% reduction in pollutants beyond the National III requirements to achieve compliance.

Can I Take Subject Four Without Passing Subject Two?

You cannot take Subject Four without passing Subject Two. The examination sequence follows Subject One, Subject Two, Subject Three, and Subject Four in order. Only after passing the previous subject can you proceed to the next one. Applicants for a motor vehicle driver's license must pass the following four subjects: Subject One (Road Traffic Safety Laws, Regulations, and Related Knowledge), Subject Two (Field Driving Skills), Subject Three (Road Driving Skills), and Subject Four (Safe and Civilized Driving Knowledge). Subject Two, also known as the small road test, is part of the motor vehicle driver's license assessment. It is the abbreviation for the Field Driving Skills test. For the C1 license, the test items include five mandatory components: reverse parking, parallel parking, hill start and stop, right-angle turns, and curve driving (commonly known as the S-curve). In some regions, there is a sixth item: highway toll card collection. For the C2 license, the test items include four mandatory components: reverse parking, parallel parking, right-angle turns, and curve driving (S-curve). For large vehicles (A1, A2, A3, B1, B2), the test items include pole parking, hill start and stop, parallel parking, single-plank bridge crossing, curve driving, right-angle turns, narrow gate passage, continuous obstacle passage, bumpy road driving, narrow road U-turns, and simulations for highways, continuous sharp mountain turns, tunnels, rain/fog conditions, slippery roads, and emergency handling. Subject Two is scored out of 100, with evaluation criteria for failing, deducting 20 points, deducting 10 points, or deducting 5 points. The passing standards are as follows: For large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, and large trucks, a score of 90 or above is required. For other vehicle types, a score of 80 or above is required.

What is a spark plug in a car?

Spark plug is an ignition device in a car used to ignite the combustible mixture inside the cylinder. The spark plug mainly consists of a terminal nut, insulator, terminal screw, center electrode, side electrode, and shell. The side electrode is welded to the shell. Under high voltage, the air between the center electrode and the side electrode of the spark plug rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain value, the number of ions and electrons in the gas rapidly increases, causing the air to lose its insulating properties. A discharge channel forms in the gap, leading to a breakdown phenomenon. At this point, the gas becomes a luminous body, and as it heats and expands, it is sufficient to ignite the mixture in the cylinder's combustion chamber.

What type of engine oil is used for the Refine S3?

Refine S3 uses 10w-30 engine oil. The Refine S3 is a compact SUV that inherits JAC's family genes in terms of silhouette and details, featuring a typical "treasure vase mouth" front grille design. The body extensively uses chrome trim strips, and the interior adopts a multi-color design concept combining orange, black, and silver, paired with a 7-inch multimedia display. The dashboard employs a layered design with large areas of hard plastic materials. The vehicle is equipped with a 1.5L engine, matched with a 6-speed manual CVT transmission, while the base Comfort trim model uses a 5-speed manual transmission.

Where is the Focus electric fan relay located?

Focus electric fan relay is located in the fuse box in the engine compartment. The replacement method for the electric fan relay: 1. First open the car's hood and remove the intake pipe located above the fan; 2. The electric fan and air conditioning fan are located on the fan bracket with four corners in total, use professional tools to unscrew these four screws; 3. When all screws are unscrewed, the relay can be removed from the car; 4. Install the new relay correctly on the new fan bracket and tighten the four corner screws; 5. Start the engine to test whether the fan can operate normally, and after checking for no errors, reinstall the intake pipe to the correct position.

What are the reasons for a vehicle stalling after starting?

Reasons for a vehicle stalling after starting: 1. Triggering the vehicle's anti-theft system: When the anti-theft system is activated, the engine automatically locks. Even if it can start, it cannot run, and the anti-theft light will illuminate. This is often caused by the owner using a non-chip key that the system cannot recognize. 2. Ignition switch failure: Poor contact of internal contacts in the ignition switch can cause the dashboard battery light, oil light, and engine fault light to not illuminate. 3. Low fuel system pressure: When the fuel system pressure is too low, the normal injection time delivers too little gasoline, resulting in a mixture that cannot be compressed and ignited. However, during startup, the extended injection time corrected by the startup program allows the gasoline to be compressed and ignited despite the low pressure. Once the vehicle starts and returns to normal injection, it stalls.
