Can Modified Exhaust Sound Pass Vehicle Inspection?

Modified exhaust sound cannot pass vehicle inspection. Introduction to Car Exhaust Sound: Car exhaust sound refers to the roaring noise caused by the rotation of the car engine. Cars equipped with V10, V12, or even V16 engines can make many people turn their heads when they roar. However, in addition to the engine itself, some modified or specially tuned exhaust systems can also produce captivating exhaust sounds. Factors Determining Exhaust Sound: Material type, muffler type, resonator length, flow restriction, and exhaust tuning. Of course, the main factor is the engine - the sound of a 4-cylinder engine is completely different from that of a V12 engine. But after tuning, both can produce heart-throbbing exhaust sounds. For example, the exhaust pipes of Mercedes-Benz AMG and Lexus LFA models, after special tuning, produce sounds referred to as "the roar of angels."

What is the Tax Basis for Passenger Vehicles?

The tax basis is determined either by mass or by price. Tax basis determined by mass: For commercial vehicles, special operation vehicles, and wheeled special-purpose vehicles, the tax basis is the curb weight per ton. Tax basis determined by price: The taxable price for a taxpayer purchasing a vehicle for personal use refers to the total price and additional fees paid by the taxpayer to the seller for the taxable vehicle, excluding VAT. In other words, the tax basis is calculated by dividing the total amount on the 'Uniform Invoice for Motor Vehicle Sales' by (1+17%), and then multiplying by 10% (5% for passenger vehicles with a displacement of 1.6 liters or less) to determine the vehicle purchase tax payable. According to regulations, buses, commercial passenger vehicles, and motorcycles are taxed per unit.

What are the safety precautions for finished vehicle loading?

Be cautious of slippery surfaces, protruding vehicle parts, and falling cargo. Be cautious of slippery surfaces: During loading operations, it is inevitable to climb on and off the vehicle. Personal safety should be highly prioritized at this time. If the soles of shoes are contaminated with oil, frost, or mud, it may reduce friction and lead to accidents. Be cautious of protruding vehicle parts: When walking near or maintaining the vehicle, pay attention to hooks, beams, side railings, and any protruding parts after loading cargo to avoid bumps and injuries. Be cautious of falling cargo: For rod-shaped or tubular cargo such as square timber, logs, wooden frames, or small rolls, be careful of collapse when tightening or loosening ropes during loading and unloading. It is best to stand on the sides of the cargo during operations. Additionally, when walking on top of such cargo, be cautious of foot entrapment. For flatbed vehicles carrying boxed or rolled cargo, observe carefully before unloading after loosening ropes. Collapses or falling cargo can cause serious injuries. Also, be careful when opening doors of railings or box trucks.

Is it correct that a car travels 80 kilometers per minute?

No. A car cannot travel 80 kilometers per minute. It should be approximately 80 kilometers per hour. Introduction to Speed: Speed is a form of expressing velocity, referring to the total distance an object travels within one hour. The unit of speed is kilometers (km) or miles per hour (mph). Speed is commonly used in the field of transportation, but it is not the standard speed unit in the International System of Units. Calculation of Car Speed: The speedometer uses the measurement signal from the speed sensor to calculate and display the car's speed. When calculating speed, one method involves counting the number of pulses output by the sensor within a fixed time, while another method measures the time taken for a fixed pulse period. The pulse counting method works as follows: when the microprocessor detects an increase in the number of pulses from the sensor signal, it starts counting the pulses representing speed. After detecting the number of pulses over a preset time, the data in the counter is compared with the data in memory. If the difference reaches one kilometer per hour or more, the counter's data is output to the display circuit to refresh the displayed value. This process repeats continuously.

At what color should engine oil be changed?

Engine oil should be changed when it turns black. New engine oil is light yellow and transparent. After being added to the engine, due to prolonged use, some carbon deposits inside will cause the oil to gradually darken. Over time, it will turn completely black. Oil changes are based on maintenance intervals and mileage, whichever comes first—typically every six months or 5,000 kilometers. Most newer models require oil changes every six months, 7,500 kilometers, or 10,000 kilometers. Engine oil, also known as motor lubricant, serves functions such as lubrication, cooling, sealing, rust prevention, and shock absorption. It consists of base oil and additives.

What cooling methods are generally used in gasoline engines?

Automobile engines have two cooling methods: air cooling and water cooling. Currently, most automobile engines use water-cooled engines. Air-cooled engines are only suitable for some small gasoline engines. Introduction to automobile engines: It is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines, steam engines), electric motors, etc. The term engine can refer to both the power generation device and the entire machine including the power unit (e.g., gasoline engine, aircraft engine). Classification of automobile engines: Depending on the power source, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrid power systems.
