What is the name of Subject 4 exam?

Subject 4, also known as Subject 4 theoretical exam or driver's theoretical exam, is part of the motor vehicle driver's license assessment. Subject 4 extracts knowledge related to safe and civilized driving requirements, safe driving skills under complex conditions, and emergency handling from the original Subject 1, and conducts it after the "Subject 3" actual road driving test to further examine candidates' traffic quality. Below is relevant introduction about Subject 4 exam: 1. The original exam consisted of Subject 1 theoretical test, Subject 2 stake test, electronic subject test, and Subject 3 road test. According to the Ministry of Public Security Order No. 123, an additional theoretical test is required after the road test. Since this test is conducted after Subject 3, it is commonly referred to as Subject 4 exam. In official terms (i.e., Ministry of Public Security Order No. 123), there is no such term as Subject 4. 2. Subject 4 extracts knowledge related to safe and civilized driving requirements, safe driving skills under complex conditions, and emergency handling from the original Subject 1, and conducts it after the "Subject 3" actual road driving test to further examine candidates' traffic quality.

What is Vehicle Urea?

Vehicle urea is primarily used to reduce harmful nitrogen oxides in exhaust gases into nitrogen and water. It is generally used in diesel vehicles. The main harmful substances in diesel vehicle exhaust are nitrogen oxides and particulate matter. While particulate emissions can be reduced through technical means within the engine, the exhaust primarily contains nitrogen oxides. By injecting urea into the exhaust after-treatment device, the urea decomposes into ammonia at high temperatures. Under the action of a catalyst, the ammonia reacts with nitrogen oxides to produce harmless nitrogen and water. This device is called the SCR (Selective Catalytic Reduction) after-treatment system. Below are detailed explanations of related content: 1. Vehicles have a dedicated urea tank where urea is stored. As long as the vehicle is running, urea will be consumed, so it needs to be replenished promptly. Generally, about 4 liters of urea are consumed per 100 liters of diesel, though this varies depending on engine displacement, model, manufacturer, etc. Different road conditions and loads can also affect urea consumption. 2. If diesel exhaust fluid (DEF) is not used, or if its purity is insufficient or its quality is substandard, the vehicle's engine may automatically reduce its speed. Additionally, substandard DEF can contaminate the catalyst in the SCR catalytic reaction tank, leading to serious consequences.

What is the battery model for the BMW 520 remote control?

BMW 5 Series car key battery model is CR2450-3V. Car key battery model classification: The battery models inside car keys include 2016, 2025, 2032, and other similar models. Battery introduction: A battery (Battery) refers to a cup, tank, or other container or part of a composite container that contains an electrolyte solution and metal electrodes to generate electric current, which can convert chemical energy into electrical energy. It has positive and negative poles. With the advancement of technology, batteries generally refer to small devices that can generate electrical energy, such as solar cells. The main performance parameters of a battery include electromotive force, capacity, specific energy, and resistance. Using a battery as an energy source can provide stable voltage, stable current, long-term stable power supply, and current that is minimally affected by external factors. Moreover, batteries have a simple structure, are easy to carry, and have straightforward charging and discharging operations. They are not affected by external climate and temperature, offering stable and reliable performance, and play a significant role in various aspects of modern social life.

What maintenance items are needed at 30,000 kilometers?

Generally speaking, the 30,000-kilometer maintenance items for a car include changing the engine oil, oil filter, air filter, fuel filter, throttle cleaning, and replacing spark plugs. Some 4S shops may recommend additional maintenance items, which can be considered based on personal preference and actual conditions. Below is a related introduction to car maintenance: 1. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. 2. Car maintenance mainly includes the maintenance scope of the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. The purpose of maintenance is to keep the car clean, maintain normal technical conditions, eliminate hidden dangers, prevent failures, slow down the deterioration process, and extend the service life. 3. The maintenance cycles of different car series and brands vary greatly due to differences in the specific technical conditions of different vehicles. Different brands of vehicles are equipped with engines of different designs. Some engines have better materials and higher precision, so the wear is relatively smaller; while some cars have higher requirements for engine oil, or even special requirements. Therefore, brand cars generally require their corresponding original engine oil for lubrication.

What was the emission standard for cars in 2013?

Vehicles manufactured after July 1, 2013 were generally compliant with China IV emission standards, as this was the deadline for China III vehicle registration. Nineteen regions including Beijing, Shanghai, Guangzhou, Shenzhen, Nanjing, Urumqi, and Lanzhou strictly implemented the China IV standard from July 1, 2013. The nationwide implementation of China IV emission standards began on January 1, 2014. Below are methods to check a vehicle's emission standard: 1. The simplest method is to check the environmental protection label on the vehicle, which clearly indicates the standard on the back; 2. Visit the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire; 3. Bring the vehicle registration certificate (original or copy) to the local vehicle management office for inquiry; 4. For new vehicles, the emission standard can be found on the vehicle's factory certificate. However, this certificate is usually kept by the vehicle management office, so it's advisable to make a copy when purchasing a new vehicle for future reference; 5. Roughly estimate based on the vehicle's registration year: most vehicles registered after 2015 are China V compliant; those registered after 2008 are mostly China IV; vehicles registered in 2007 could be either China III or China IV; vehicles registered before 2007 are generally below China IV, meaning China II or China III; and vehicles registered before 2005 are mostly China II compliant.
