Open the windows. Ventilating a new car is highly beneficial for removing odors, not only eliminating the peculiar smells of a new vehicle but also allowing fresh air to circulate inside, which greatly aids the overall air circulation within the car. Here are some relevant details: 1. Benefits of opening windows for ventilation: Exposing a new car to sunlight is intended to accelerate the mobility of formaldehyde molecules, thereby helping to dissipate the formaldehyde gas retained inside the car. However, this doesn't mean the car should be left in continuous direct sunlight, as prolonged exposure can accelerate the aging of interior upholstery and even release more harmful gases, which would be counterproductive. 2. Precautions when opening car windows: While driving, avoid opening all windows simultaneously as this can cause chaotic airflow inside the car. Small items placed inside the car can easily be blown over by the strong airflow, potentially causing damage or injury. It is also advisable not to open windows when driving on highways, as doing so is undesirable from various perspectives including fuel consumption, noise, and safety. Additionally, when using the air conditioning, it's important to balance the use of internal and external air circulation to ensure adequate air exchange inside the vehicle.

Is Engine Oil Consumption High During Long-Distance Driving?

Generally, driving on highways with stable conditions doesn't lead to significant engine oil consumption. However, turbocharged engines typically consume some oil, which is considered normal. Excessive oil consumption can be attributed to the following reasons: 1. Piston ring wear or damage, misaligned or incorrectly installed piston rings: Worn piston rings lose their elasticity, reducing the pressure on the cylinder walls and diminishing their oil-scraping effectiveness. 2. Excessive clearance between the piston and cylinder wall: When the fit between the piston and cylinder wall becomes too loose, or the cylinder wears into a conical or oval shape, the piston rings, piston, and cylinder wall cannot seal properly. This allows splashed oil to enter the combustion chamber through the gaps and burn, leading to a sharp increase in lubricating oil consumption.

How is the horsepower of a car calculated?

The calculation method for a car's horsepower: Horsepower is calculated from torque, and the formula is; power (kw) torque (n-m) multiplied by speed (rpm) divided by 9549. The horsepower of an engine refers to the size of the engine's output capability (work done), that is, the output power, which is a very important parameter for measuring car performance and is used to evaluate engine performance. Horsepower, torque, and speed are essentially three interrelated parameters. The need for horsepower in a car is mainly for better handling performance and good acceleration performance, but horsepower is not the only parameter. There are many other factors that affect car performance, such as torque, power ratio, etc.
