How many hours of practice are required for Subject 3 before taking the test?

Subject 3 requires 24 hours of practice before taking the test. According to relevant regulations, during the validity period of the driving skill test permit, the number of scheduled tests for Subject 2 and Subject 3 road driving skills must not exceed five times. If the fifth scheduled driving test is still failed, the results of other subjects that have been passed will be invalidated. Notes for Subject 3 test: 1. The Subject 3 test requires driving on the road with many uncertainties, so make sure the car door is securely closed and the seat belt is fastened; 2. When performing the roadside parking operation, it is better to park a bit farther than to run over the curb; 3. For safety reasons, always check for oncoming traffic before opening the door when getting out of the car.

What are the benefits of cleaning the engine?

Cleaning the engine has the following benefits: 1. Remove carbon deposits, gum, and other harmful substances inside the engine. 2. Neutralize long-term harmful acidic substances generated inside the engine. 3. Prevent the mixing of old and new engine oil, and eliminate sludge and oil films formed by old oil to avoid reducing the performance of new oil. 4. Improve engine efficiency, reduce noise, and decrease fuel and oil consumption. 5. Clean the engine lubrication system, enhance oil fluidity, lower engine temperature, and improve lubrication effectiveness. The car engine is the machine that provides power to the vehicle, acting as the heart of the car, influencing its power, fuel economy, and environmental friendliness. Depending on the power source, car engines can be classified into diesel engines, gasoline engines, electric vehicle motors, and hybrids, among others.

How to Identify China 5 and China 6 Vehicle Emission Standards?

Methods to distinguish between China 5 and China 6 vehicle emission standards are as follows: 1. First, you need to know the complete vehicle model number of the car you want to check, which is usually marked on the vehicle's nameplate. 2. Visit the Motor Vehicle Environmental Protection Website, enter the fuzzy condition (complete vehicle model number) in the input box on the webpage, then input the correct verification code, and click 'Query' to find the relevant information of the vehicle, including the emission standard. If the 'Stage' marked is 4, it indicates that the vehicle complies with the China 4 emission standard. 3. You can also check the vehicle's conformity certificate or the environmental information list that comes with the vehicle.

How to Deal with Strong Odor in a New Car?

New cars almost always contain several toxic substances such as formaldehyde, benzene, acetone, and xylene, which are the main culprits of air pollution inside the vehicle. Components like leather seats, chemically treated decorative panels, and easily accessible engineering plastics, rubber, and synthetic fabrics can emit unpleasant odors when the car is new or during extreme weather conditions (such as after being exposed to intense sunlight), posing risks to human health and safety. The sources of odors inside a car typically fall into three categories. The first source is the new car itself. A car is composed of many parts, and if the harmful gases and odors from these parts are not sufficiently released, they can pollute the cabin for a long time. The second source is the interior decorations. Materials used in decorations contain harmful gases such as benzene, formaldehyde, acetone, and xylene, which can contribute to varying degrees of air pollution inside the car. The third source is the use of air conditioning or poor cabin sealing, allowing pollutants like sulfur dioxide, carbon dioxide, and evaporated gasoline to enter and contaminate the interior. To eliminate odors from your beloved car. Bamboo charcoal bags have a strong ability to absorb odors, making them a highly effective and long-lasting solution for removing unpleasant smells inside the car. Bamboo charcoal bags can selectively adsorb various substances in the air to achieve disinfection and deodorization. Additionally, bamboo charcoal bags are affordable, easy to purchase, and excellent for odor removal. It is recommended to use bamboo charcoal bags, replacing them every three months. Car owners, especially those with new cars, should develop the habit of opening doors and windows before driving to allow circulating air to dilute and disperse toxic gases inside the cabin. During driving, keeping windows open as much as possible helps blow away toxic fumes and accelerates the process of eliminating odors in the new car.

What to Do If 95 Octane Is Mixed with 92 Octane?

Occasionally mixing 95 octane gasoline with 92 octane is not a problem. Here are the relevant details: 1. Long-term use of lower octane gasoline in high-octane vehicles can severely affect engine performance, leading to knocking and potentially reducing engine lifespan while increasing maintenance costs. 2. The fundamental difference between 95 octane and 92 octane gasoline lies in their octane ratings, essentially meaning they contain different proportions of anti-knock additives. 95 octane gasoline has a slightly higher proportion of anti-knock additives compared to 92 octane. The quality of both fuels is identical, with no difference in cleanliness or other factors; the only variation is the amount of anti-knock additives, designed to meet the different anti-knock requirements of engines with varying compression ratios.

What are the methods for testing automotive engine power?

There are two main methods for testing automotive engine power: 1. Steady-state power testing (load testing or external load testing): Steady-state power testing refers to a method of measuring engine power on a dynamometer when the throttle opening, engine speed, and other parameters remain constant in a stable state. 2. Dynamic power testing (no-load testing or external load-free testing): Dynamic power testing refers to a method of measuring engine power when parameters such as throttle opening and engine speed are in a changing state. According to the power testing principle, dynamic power testing can be divided into two categories: (1) Measuring instantaneous power by determining instantaneous angular acceleration, which is an instrument solution that obtains instantaneous power by measuring the acceleration at a certain speed during the acceleration process. (2) Measuring average power by determining acceleration time, which is a solution that obtains average acceleration power by measuring the acceleration time within a certain speed range during the acceleration process.
