An automobile generally consists of four basic components: the engine, chassis, body, and electrical equipment. The following is an introduction to engine-related content: 1. Energy conversion: An engine is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines typically convert chemical energy into mechanical energy. 2. Device: The term 'engine' can refer to both the power generation device and the entire machine including the power unit (e.g., gasoline engines, aircraft engines). The engine was first developed in the UK, so the concept of the engine originates from English, with its original meaning referring to 'a mechanical device that generates power.'

Hey, do you know what you see first when you sit in the driver's seat? The steering wheel connects to the dashboard, where the tachometer and speedometer are must-watch gauges while driving. Below the steering wheel, there's a lever controlling the turn signals, and at your feet, the left side has the clutch or a dead pedal, the middle is the crucial brake, and the right is the accelerator pedal. The seat can be adjusted forward and backward, and some can even adjust height and lumbar support. The center console is lively—air conditioning knobs, music players, and nowadays many cars come with a large touchscreen for operation. The gear shift is in the middle or behind the steering wheel, with clear markings for P, R, N, D. The roof has reading lights and sun visors, while the door panels hide window switches and mirror adjustment buttons. Storage spaces are designed everywhere, especially the armrest compartment which can hold a lot. That click sound from the seatbelt buckle brings peace of mind once it's fastened.

Last time I accompanied a friend to pick up their new car, I took the opportunity to thoroughly examine it from the front passenger seat. The dashboard in front of the windshield was covered with soft material, and some cars even had decorative stitching. It's worth noting that the A-pillar can sometimes obstruct visibility. The steering column can be adjusted both up/down and forward/backward, and the steering wheel now comes packed with an intimidating array of functions—switching songs, answering calls, and cruise control are all handled there. The window buttons conceal a heated mirror switch nearby, which proves especially useful on rainy days. The central console hides USB ports and a cigarette lighter socket, which is essential for charging phones. The overhead sunroof controls and glasses compartment are thoughtful touches, while the door panel storage slots are perfectly sized for water bottles. A simple pull on the adjustment lever nestled in the seat seam reclines the backrest effortlessly.

When I was practicing for the driver's license test, the instructor told me to get familiar with every control component. The throttle, brake, and clutch each have their own feedback resistance when pressed. You need to memorize how many turns of the steering wheel are needed to reach full lock. When the fuel gauge on the dashboard lights up yellow, you should refuel immediately. The central locking button is located above the driver's door handle, and the rearview mirror adjustment knob must be turned in the correct direction. When shifting gears, you must press the brake to move the gear lever. Nowadays, parking brakes are mostly electronic buttons, while handbrakes are less common. The sun visor can be flipped down and also rotated sideways to block the sun. The headrest height should be adjusted properly to protect the neck in an emergency. The seat belt height can also be fine-tuned.
