Because cars need fuel to start. Reasons: Because cars use internal combustion engines as their power source, and internal combustion engines include gasoline and diesel engines. A gasoline engine is an engine that uses gasoline as fuel to convert internal energy into kinetic energy. Due to gasoline's low viscosity and rapid evaporation, a fuel injection system can be used to inject gasoline into the cylinder. After compression reaches a certain temperature and pressure, a spark plug ignites it, causing the gas to expand and perform work. Characteristics of gasoline engines: High speed, simple structure, lightweight, low cost, smooth operation, and easy maintenance. Gasoline engines are widely used in cars, especially in small vehicles.

What are the functions of the buttons in the Equinox?

The central control buttons are as follows: 1. Electronic Stability Program (ESP): Effectively prevents body skidding, fishtailing, and other loss-of-control situations. It is generally not recommended for drivers to manually turn it off. 2. Parking Radar/Image: This button activates the panoramic image and radar functions, providing alerts and visual feedback to help the driver detect surrounding obstacles. 3. Auto Start-Stop: When this function is activated, the engine will temporarily shut off. When the driver's foot leaves the brake pedal, the vehicle will restart. 4. Recirculation/Fresh Air: Recirculation means the air inside the car is heated or cooled and then recirculated, while fresh air allows outside air to enter the car. Use recirculation in environments with heavy exhaust, dust, or smog, such as during traffic jams. On highways, it is advisable to periodically switch from recirculation to fresh air, and the recirculation duration should not exceed one hour. 5. Temperature Zone Sync: This function ensures that changing the temperature in the driver's zone will adjust the other zones accordingly. When this function is turned off, each temperature zone can be controlled separately.

How to Calculate Safe Driving Distance?

Methods for calculating safe driving distance: 1. When a motor vehicle is driving on the highway at a speed exceeding 100 km/h, the safe distance should be more than 100 meters; 2. When the speed is below 100 km/h, the minimum safe distance should not be less than 50 meters. It is essential to maintain a safe driving distance, as many rear-end collisions occur due to excessive speed and failure to keep a safe distance from the vehicle ahead. The safe distance can also be influenced by various other factors, such as weather conditions, light intensity, driver's vision, braking equipment, and road conditions. Especially in adverse weather conditions, the required braking force, braking distance, and the distance traveled at the original speed during the reaction time all increase accordingly, necessitating a longer safe distance.

What are the body dimensions of the Regal?

The body dimensions of the Regal are 4902mm in length, 1863mm in width, and 1456mm in height, with a wheelbase of 2829mm. The space performance in both the front and rear rows is quite good. The Regal is a mid-to-high-end midsize sedan produced by the American automaker Buick. The new front-end design of the Regal further emphasizes its elegant and dynamic characteristics. The slim and straight wing-shaped chrome trim extends to the LED daytime running lights on both sides, creating a more direct and continuous effect. The iconic LED daytime running lights are creatively placed at the bottom of the headlights, complementing the air curtain design on both sides of the front bumper. These attention to details make the new Buick Regal appear lower, wider, and full of dynamism.

How to Set Cruise Control on the LaCrosse?

To set cruise control on the LaCrosse: 1. Press the cancel button to deactivate cruise control, then press the RES button to resume it; 2. The SET button is used to set the cruising speed, which should be adjusted using this button before activating cruise control; 3. The +/- buttons control the cruise control speed, increasing or decreasing it accordingly. The autonomous driving system mainly includes lane keeping and adaptive cruise control. Compared to a warning system, lane keeping also controls the braking mechanism. When the vehicle deviates from the lane and shows a tendency to cross the line, the system intervenes by applying the brakes and issuing a warning. Adaptive cruise control eliminates the need for frequent cancellation and resetting, intelligently adjusting the following speed to maintain a safe distance.

How Long Does It Take for Alcohol Sprayed in the Car to Evaporate?

Alcohol sprayed inside the car generally evaporates within 10 minutes. Opening the car windows for timely ventilation can accelerate the evaporation process. When spraying alcohol in the car, it should be done after turning off the engine and powering down the vehicle. After spraying, the car should be parked in a cool and safe location with the doors open to allow the alcohol to evaporate quickly. Avoid using any disinfectant or alcohol to directly wipe leather parts or chrome-plated decorations in the car, as this may cause corrosion, discoloration, whitening, or other irreversible damage to the leather or interior components. If no other disinfectants are available and alcohol must be used for car disinfection, ensure that the process is conducted safely.

What Does the Motor Oil Grade Mean?

Motor oil grades consist of two parts: classification and viscosity specification. The oil grade usually indicates viscosity and quality. The smaller the number in front, the better the low-temperature fluidity of the oil, representing a lower usable ambient temperature and better protection for the engine during cold starts. The number after "w" is an indicator of the oil's high-temperature resistance, with larger values indicating better protective performance at high temperatures. Motor oil, also known as engine lubricant, serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. Automotive lubricants are categorized into mineral lubricants, synthetic lubricants, and semi-synthetic lubricants.
