What is the meaning of eTSI engine?
Mild hybrid (eTSI). These are petrol engines that are coupled to a 48 V system plus 7-speed dual clutch gearbox (DSG). A 48 V belt starter generator, a 48 V lithium-ion battery and the latest generation of pioneering, efficient TSI engines mean perfect performance while significantly cutting fuel consumption. A car with eTSI technology is equipped with a proven combustion TSI engine and a small electric motor functioning as a starter-generator. This electric motor operates either in alternator mode to charge the 48V batteries or in boost mode to assist the combustion engine in powering the vehicle.Cars labeled as eTSI are equipped with a mild-hybrid drivetrain. This means that the vehicle is powered by a traditional internal combustion engine, which is assisted by an electric motor. TSI vehicles are not capable of running solely on electric power.
Which is better TDI or TSI?
Of course, speed and performance isn’t everything – if you want a smooth, quiet drive, the TSI is far superior to the TDI. The TSI engine runs with significantly less vibration than the TSI and it doesn’t transmit anything harsh into the cabin under heavy acceleration. TSI engines will be most fuel-efficient in urban areas and are ideal if most of your driving is carried out around town. They also usually provide better performance than TDI engines, thanks to their quick acceleration and lightweight build.TSI technology brings more efficiency from smaller units — resulting in the ability to travel longer distances from less fuel. Built to be strong and light, TSI engines all deliver high specific torque from much lower revs, to make Volkswagen cars more lively, economical and clean-running.The top-of-the-range 1. TSI engine benefits from improvements brought about by the new catalytic converter, which boasts improved efficiency and reaches its operating temperature more quickly. Moreover, it comes with upgraded software for the ACT+ active cylinder deactivation system.Turbo Stratified Injection – TSI TSI is our pioneering technology for petrol engines. TSI engines are compact, high-powered and use less fuel. TSI technology blends the best of our TDI diesel and FSI (fuel stratified direct injection) petrol engines to give you excellent driveability and outstanding fuel economy.
