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.

Which engine is used in the Bestune T77?

The engine of the Bestune T77 is independently developed by China's Bestune brand and is a domestically produced engine. The engine model of the Bestune T77 is CA4GA12TD, with a maximum power of 124kW, a maximum torque of 258 N·m, and a maximum horsepower of 169. For daily maintenance of the Bestune T77's engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine problems. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, bypassing through the relief valve and carrying contaminants back to the lubrication area, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, 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 operates normally but also extends the overall lifespan of the radiator and engine.
