What does TSI mean for Volkswagen cars?

[Archie]

TSI in cars refers to a twin-charged engine. The following are the maintenance methods and working principles of the engine: Engine maintenance methods: Use high-quality engine oil, use qualified coolant, regularly clean the radiator scale, regularly remove carbon deposits from the engine, replace the vehicle's air filter, oil filter, and fuel filter on time, check the condition of the spark plugs, and maintain normal engine speed. Engine working principle: Mix air and gasoline in a certain proportion to form a combustible mixture, which is then drawn into the cylinder during the intake stroke. The compressed mixture ignites and burns, generating heat energy. 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.
