What are the three major components of a sedan?

The three major components of a sedan refer to the engine, transmission, and chassis. The engine's function is to convert the thermal energy of gasoline or diesel into mechanical energy by burning and expanding the gas inside a sealed cylinder, thereby pushing the piston to perform work. The functions of the transmission are: 1. Changing the transmission ratio to meet the traction needs under different driving conditions; 2. Enabling reverse driving. The maintenance methods for the engine include: 1. Using qualified engine oil; 2. Using qualified coolant and antifreeze; 3. Regularly cleaning the radiator scale; 4. Regularly removing engine carbon deposits; 5. Regularly replacing the car's three filters; 6. Maintaining a reasonable engine speed.
I've been driving for over 20 years, and the three major components of a sedan are the core parts: the engine, transmission, and chassis. The engine is the heart of the car. When I drove an old clunker, the engine burned oil, making it difficult to start, and it buzzed loudly when running, not to mention being fuel-inefficient and dangerous. Transmissions come in manual and automatic. My first manual transmission shifted smoothly and was durable, but an automatic is much more comfortable for long trips—just don't wait until it starts jerking to get it fixed. The chassis includes the suspension and affects cornering stability. My hometown has many mountain roads, and a loose chassis makes the car feel floaty. Maintaining these three major components well extends the car's lifespan and ensures safety. I recommend regular oil changes and inspections for new cars, and paying extra attention to unusual noises in older cars. Keep an eye on the temperature gauge, and address rust on the chassis early—these small habits have saved me a lot on repair costs.
Buddy, talking about cars gets me all fired up! The three core components of a sedan are absolutely essential—the engine, transmission, and chassis. The engine is like the heart of a race car; for example, turbocharging gives you that exhilarating kick. Manual transmissions are fun for control freaks, while automatics are hassle-free but lack some excitement. A well-tuned chassis keeps you steady even when taking sharp turns at high speeds. Only when these three components work in perfect harmony does the car truly come alive. Like my old ride after I took it to the tuning shop for chassis upgrades—with reinforced suspension, I can tear through mountain roads without fear of losing control. When buying a car, prioritize test drives to check power response and smooth gear shifts. Don’t just fall for flashy looks, or you’ll end up broke and frustrated fixing crappy core components. Regular maintenance is key for these three—using high-quality oil can reduce wear and tear, saving you money and keeping you safe in the long run.
