How Often Should a Car's Motor Be Replaced?

Why does the domestic Model 3 only show 380km when fully charged?

It is normal for the system to display 380km after the Model 3 is fully charged. This value is an estimate and does not strictly mean the Model 3 can only run 380km. The NEDC reference data provided for the domestic Model 3 is a range of 445km, which is calculated according to the international driving cycle method. Both values are for reference and do not represent the exact range of the vehicle. Below are the specific details of the vehicle parameters: 2022 Model 3 has a body size of 4694mm*1850mm*1443mm, a top speed of 225km/h, and accelerates from 0 to 100km/h in 6.1 seconds. It is equipped with a permanent magnet synchronous motor with a maximum power of 194kw and a maximum torque of 340mm. The battery type is lithium iron phosphate with an energy capacity of 60kwh, supporting fast charging in 1 hour and slow charging in 10 hours. The transmission is a single-speed fixed gear ratio. In daily life, the power consumption of the car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase power consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the accelerator before a red light, can increase power consumption. The car itself: Heavier cars consume more power because greater driving torque is required for their weight. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and power consumption. Natural wind: Driving against the wind or on windy days increases car resistance and power consumption. Low environmental temperature: In cold weather, the car's computer may control the generator to run at higher speeds to warm up the car, which also increases power consumption.

Why doesn't the Avalon have a lock confirmation sound?

The lock sound of the Avalon needs to be set manually. The method to set the lock sound for the Avalon is as follows: turn off the vehicle and ensure all four doors are closed, then simultaneously press the lock and unlock buttons on the remote key for more than three seconds. This will toggle the lock sound on or off, serving as a reminder when locking the vehicle. Below is additional information about the Avalon: 1. The Avalon is equipped with a 2.5L naturally aspirated engine, with a maximum power of 154kW and a maximum torque of 250Nm. 2. It is paired with an 8-speed automatic transmission, featuring a front suspension type of MacPherson strut independent suspension and a rear suspension type of E-type multi-link independent suspension. 3. The Avalon is a mid-size car under Toyota, with dimensions of 4975mm in length, 1850mm in width, and 1450mm in height, and a wheelbase of 2870mm. 4. The fuel tank capacity of the Avalon is 60L, and it uses 215/55R17 tires.

Is it okay for tires to be soaked in water overnight?

Tires being soaked in water overnight is not a problem, and even long-term soaking in water will not have any impact. However, standing water has a very significant effect on the wheel hubs and brake components such as brake calipers, brake pumps, and brake discs. It's important to know that tires themselves are rubber products, and standing water is essentially "impervious" to them. Below are solutions for dealing with rust on car parts after being soaked in water: 1. Fine sandpaper polishing: If rust does occur, it's not without a solution. Simply polishing with fine sandpaper will suffice. 2. Replacement when necessary: However, if the corrosion is already very severe, replacement is absolutely necessary. Even if the rusted parts on the surface are polished off as much as possible, it will still affect the braking performance.

How often should a car undergo annual inspection? How to conduct the annual inspection?

After the implementation of the new vehicle inspection regulations, new private cars with 7 seats or below (including 7 seats) do not need to undergo annual inspection within the first 6 years. For cars older than 6 years but less than 10 years, the inspection is required every 2 years. The vehicle must undergo on-site inspection at the testing station during the 6th and 8th years. For private cars older than 10 years, the original inspection cycle still applies: cars between 10 and 15 years old must be inspected once a year, while cars older than 15 years must be inspected every six months. Below are the precautions for cars that have not undergone annual inspection: 1. Accident liability: For any traffic accidents caused by vehicles that have not participated in the annual inspection on time, the party involved will bear full or primary responsibility, and the insurance company will not be liable. This is because the insurance policy specifies that vehicles with expired inspection are among the objects of claim rejection. 2. Mandatory scrapping: According to the "Regulations on the Compulsory Scrapping Standards for Motor Vehicles", if a motor vehicle fails to obtain the inspection qualification mark for three consecutive inspection periods after the expiration of the inspection validity period, it will be compulsorily scrapped.

Where is the Qoros 7 car engine produced?

The engine of the Qoros 7 is produced in Sichuan by Brilliance. This car uses BMW's Prince engine. The engine model used in the Qoros 7 is PSARFN10LH3X, with a maximum horsepower of 147 HP, a maximum power of 108 KW, a maximum power speed of 6000 rpm, and a peak torque of 200 N.m. For the daily maintenance of the Qoros 7's engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to the mechanical load, with the selection standard not lower than the requirements specified by the manufacturer. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, which can cause various problems for the engine. To avoid faults, change the oil regularly based on usage conditions and keep the oil volume moderate. When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to pass through the bypass valve and bringing contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, water, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. When the amount is small, it suspends in the oil; when large, it precipitates from the oil, blocking the filter and oil holes, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine works properly but also extends the overall lifespan of the radiator and engine.
