What does TSI at the back of a car mean?

[EstherDella]

TSI at the back of a car refers to a twin-charged engine. The functions of the engine are: 1. To fully combust the fuel input into the cylinders and generate power; 2. To determine the vehicle's power, fuel efficiency, stability, and environmental friendliness. The maintenance methods for the engine include: 1. Using qualified engine oil; 2. Using qualified coolant; 3. Regularly cleaning the water tank scale; 4. Regularly removing carbon deposits from the engine; 5. Timely replacing the vehicle's air filter, oil filter, and fuel filter; 6. Checking the condition of the spark plugs; 7. Maintaining normal engine speed. The principle of the engine is: 1. Mixing air and gasoline in a certain proportion to form a combustible mixture; 2. The intake stroke draws the mixture into the cylinder, where it is compressed, ignited, and burned to produce thermal energy; 3. The high-temperature, high-pressure gas acts on the top of the piston, pushing the piston to perform linear reciprocating motion, and the mechanical power is output externally through the connecting rod, crankshaft, and flywheel mechanism.
