Does replacing the rear crankshaft oil seal affect the engine and transmission?

How many points are deducted for littering on the highway?

Littering on the highway deducts 6 points. If the litter causes an accident involving other vehicles, the offender will bear corresponding accident liability. Legal basis: Article 48 of the "Road Traffic Safety Law of the People's Republic of China": The load of a motor vehicle shall comply with the approved loading capacity, and overloading is strictly prohibited; the length, width, and height of the load shall not violate loading requirements, and the transported goods shall not be spilled or scattered. When transporting oversized indivisible items that may affect traffic safety, the motor vehicle shall travel at the time, route, and speed designated by the traffic management department of the public security organ, with clear signs displayed. Indivisible items: Transporting oversized indivisible items on highways shall comply with the provisions of the Highway Law. Transporting explosives, flammable and explosive chemicals, highly toxic, radioactive, and other hazardous materials by motor vehicle shall be approved by the public security organ, and the vehicle shall travel at the designated time, route, and speed, with warning signs displayed and necessary safety measures taken.

What engine does the Civic have?

The Civic is equipped with two engine models: L15C8 and L15C7. The L15C8 engine has a maximum horsepower of 182 HP, a maximum power output of 134 kW at 6000 rpm, and a peak torque of 240 N·m. The L15C7 engine has a maximum horsepower of 129 HP, a maximum power output of 95 kW at 5500-6000 rpm, and a peak torque of 180 N·m. The engines used in the Civic employ imported technology and are assembled in China. For daily maintenance of the Civic engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD-SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions. For diesel engines, choose CB-CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the engine oil and oil filter. The quality of any grade of lubricating oil will degrade over time. After a certain mileage, its performance deteriorates, leading to various engine issues. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter or open the safety valve, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures the engine operates properly but also extends the overall lifespan of the radiator and engine.

Do electric vehicles require a driver's license in 2021?

In 2021, riding an electric vehicle requires a driver's license. The new national standard "General Technical Conditions for Electric Motorcycles and Electric Light Motorcycles" stipulates: Electric bicycles weighing over 40 kilograms with a speed exceeding 20 kilometers per hour will be classified as light electric motorcycles or electric motorcycles, falling under the category of motor vehicles. This regulation will be implemented from January 1, 2010. This means that once this national standard is in effect, riding an electric vehicle will require going through a series of procedures such as obtaining a driver's license, registration, and purchasing insurance. Classification of electric vehicles: Electric vehicles are now divided into two types: electric bicycles, which are non-motorized vehicles, and electric light motorcycles and power motorcycles, which are motor vehicles. According to the "New National Standard Regulations for Electric Vehicles," electric bicycles do not require a driver's license, while electric light motorcycles and power motorcycles do. The rules and mandatory requirements for driver's license examinations, as well as the implementation time of the regulations, vary from place to place.

Does illegal photography capture speeding?

No, it does not capture speeding. Navigation alerts indicating speed camera presence are what trigger speed capture. Speed cameras: Speed cameras primarily assist radar guns in operation. When radar detects speeding, the camera takes photos. Therefore, speed cameras are solely responsible for photographing speeding vehicles. Working principle of traffic violation cameras: Electronic traffic enforcement systems work by embedding induction loops beneath road surfaces to detect passing vehicles. Signals are then transmitted to a central processor and cached in registers. Captured violation data is sent to backend systems, while non-violation footage is automatically deleted after one traffic light cycle.

Is it normal for a manual transmission car to have 3000 RPM at 100 km/h?

Due to differences in vehicle models, the RPM at 100 km/h can vary slightly. Typically, most models maintain around 2500 RPM at 100 km/h, but it's also normal to reach 3000 RPM when driving uphill at this speed. Manual transmission cars with engines below 2.0L displacement: For manual transmission cars with engines below 2.0L displacement, when the speed reaches 100 km/h, the engine RPM is usually around 3000. The RPM for AT transmissions is similar to manual transmissions or slightly lower, while CVT transmission models have the lowest RPM. Advantages of lower RPM: Of course, it's not necessarily better to have lower RPM at high speeds. Lower RPM indicates that the engine can deliver high torque at lower RPM ranges, with sufficient torque, and the highest gear ratio of the transmission is small enough. Meeting these two conditions allows for lower RPM. However, RPM alone cannot be used to judge the quality of an engine. Naturally, lower engine RPM reduces wear and improves fuel efficiency.

Can You Carry a Passenger During the Motorcycle Break-in Period?

Motorcycles can carry passengers during the break-in period. Just avoid excessively high RPMs. Generally, the break-in period for a new motorcycle is 1,200 kilometers, and the engine should fully break in around 1,600-2,000 kilometers. Introduction to the Motorcycle Break-in Period: The break-in period of a motorcycle refers to the adaptation phase after purchasing a brand-new bike. Since the motorcycle is unused at the time of purchase, the engine components and endurance require some time to adjust—this is called the break-in period. During this time, it's best not to exceed speeds of 60 km/h or carry loads over 50 kilograms. Avoid continuous rides longer than two hours at a time, and remember to change the engine oil frequently. Break-in Period Precautions: During the break-in period, strictly adhere to speed limits, load restrictions, and scheduled maintenance to minimize wear on the engine and transmission components. This also helps optimize the new motorcycle's performance and extend its service life.
