Installing a small spoiler on a car is not regulated by traffic police because it is legal; however, if you install an exaggeratedly large spoiler, you need to register it with the vehicle management office in advance. Illegal modifications include replacing the vehicle's exterior panels, changing the original car logo, altering engine performance, removing seats, etc. According to relevant regulations, no unit or individual is allowed to arbitrarily change the registered structure, construction, or features of a motor vehicle. Motor vehicles must comply with national safety technical standards upon leaving the factory, and altering the factory settings is not permitted. Car modification refers to changes made to the external appearance, interior, and mechanical performance of a vehicle based on the owner's needs, primarily including body modifications and performance modifications.

Why does the 2011 Teana one-button start sometimes not respond?

Here are the reasons why the 2011 Teana one-button start sometimes doesn't respond: ECM fuse failure: It is recommended to check the ECM fuse, that is, whether the main power line of the engine control unit is normal. If not, it needs to be replaced. IPDM control unit failure: Check the IPDM control unit, which is the intelligent control unit. If the IPDM control unit wiring harness connector has poor contact, it will affect the normal use of the one-button start function. Battery or key power failure: Check whether the battery voltage is sufficient, and also check whether the key battery is low on power. If there are any of the above problems, the power needs to be replenished or the battery replaced in time.

What is the method to extinguish a fire after an engine catches fire?

When a car engine catches fire, you should stop the vehicle promptly and use the onboard fire extinguisher to spray into the gaps of the grille, then open the hood to extinguish the fire with the extinguisher. Below are detailed introductions about car engines: 1. Overview: The car engine is the device that provides power to the vehicle, determining its power, fuel efficiency, stability, and environmental friendliness. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrids, among others. 2. Others: Common gasoline and diesel engines belong to reciprocating piston internal combustion engines, which can convert the chemical energy of fuel into the mechanical energy of piston movement and output power. Gasoline engines have high rotational speeds, are lightweight, produce less noise, are easy to start, and have low manufacturing costs. Diesel engines have a high compression ratio, excellent thermal efficiency, and better economic and emission performance than gasoline engines.

Is the BMW 5 Series equipped with a 4-cylinder or 6-cylinder engine?

Domestic BMW 5 Series models are all equipped with 4-cylinder engines. For imported BMW 5 Series, there are both 4-cylinder and 6-cylinder engine options. Definition of cylinder count: Cylinder count refers to the number of cylinders in an engine. Common cylinder counts for automotive engines include 3, 4, 6, 8, 10, and 12 cylinders. Engines with displacement below 1 liter typically use 3 cylinders, those between 1-2.5 liters generally use 4 cylinders, around 3 liters usually employ 6 cylinders, approximately 4 liters use 8 cylinders, and above 5.5 liters utilize 12-cylinder engines. Relationship between cylinder count and displacement: Generally speaking, with the same cylinder bore diameter, more cylinders mean greater displacement and higher power output. With the same displacement, more cylinders allow for smaller bore diameters, enabling higher engine speeds and consequently greater power enhancement.

Is the BMW 330i's acceleration smooth?

BMW 330i's acceleration is smooth, with a 0-100km/h acceleration time of 6.2 seconds. The 2.0L engine it is equipped with has a maximum power of 258 horsepower (190 kilowatts) and a maximum torque of 400 Newton-meters. The transmission uses an 8-speed automatic manual transmission. Acceleration values of other models: Generally, 1.6L compact cars have a 0-100km/h acceleration time between 11 to 13 seconds, 2.0T mid-size cars between 7 to 8 seconds, while supercars mostly have an acceleration time of less than 3.8 seconds. Factors affecting acceleration: Mainly the engine. Among the same displacement, models equipped with turbocharged engines have obvious advantages in the 0-100km/h acceleration project, because their output power is stronger, and the output range of maximum torque is very wide, allowing the vehicle to have maximized acceleration ability at very low speeds.

Can the fuel be extracted from the X-Trail's fuel tank?

The fuel can be extracted from the X-Trail's fuel tank, but specialized fuel extraction tools are required. Method for extracting fuel: You can disconnect the metal fuel pipe in front of the fuel nozzle from the connected hose, insert the hose into a fixed container, and then turn the engine key to the drive position—never to the start position. The fuel pump will then pump out the gasoline. However, this operation is generally not recommended due to numerous potential hazards. Precautions for fuel extraction: Check whether the vehicle's engine is in an overheated state; if it is, do not risk operating, as it can easily cause accidents. Do not operate alone; it is better to have two people cooperate. Ensure the oil container is securely fixed, and the oil pipe is properly inserted into the container. Do not extract fuel for an extended period or in large quantities; generally, it should not exceed 10 seconds, otherwise, it may easily lead to other malfunctions or accidents.

How many points are deducted for stopping midway during the Subject 2 driving test?

Stopping once during the Subject 2 driving test deducts 5 points. Below is a detailed introduction about the Subject 2 test: 1. Overview: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment and is the abbreviation for the field driving skills test. The test items for small cars (C1/C2) include five mandatory components: reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving through curves. 2. Others: If the first attempt at the Subject 2 test is unsuccessful, a retake is allowed. If the retake is not attended or is still unsuccessful, the test is terminated, and the applicant must reschedule the test after ten days. Within the validity period of the driving skills test permit, the number of scheduled tests for Subject 2 and Subject 3 (road driving skills) must not exceed five times.
