What is TSI Engine? How does it work?

One of the most important developments for the Volkswagen group in recent years is the production of TSI engines. If you have driven Volkswagen group vehicles or have people around you, you are aware of TSI engines. At least you’ve heard of his name. However, you probably don’t know what this abbreviation actually means. So what exactly does TSI mean? TSI is Turbo Stratified Injection, as turbo layered injection.

When you drive one of the TSI powered vehicles, you don’t have to choose between performance and economy. TSI engines not only reduce fuel consumption and CO2 emissions but also offer an enjoyable drive. Since TSI engines have less CO2 emissions, they also save you from car tax in countries where tax is charged according to the amount of CO2 emission. As in our country, small-volume TSI engines are preferred in countries where taxes are charged according to the size of the engine volume. Because these engines can offer high horsepower with low volume.

 

How Does TSI Engine Work?

TSI engines are compact, high powered, and use less fuel. Basically, the Volkswagen TSI engine uses a combination of the turbocharger and direct fuel injection for impressive and maximum benefit. With this technology, it is aimed to achieve greater power and high fuel savings by reducing the engine volume. Combining direct injection technology with turbocharger technology, it has been provided to produce high torque and horsepower that exceeds the size of small-volume engines. With smaller designs and highly efficient combustion, TSI engines produce maximum power with minimum fuel consumption. TSI engines are designed to achieve maximum torque from low engine speeds of 1500 or 1750 rpm. This not only increases your driving pleasure but also reduces fuel consumption.

The turbocharger system in TSI engines has a water-cooled intercooler with a low-temperature circuit, independent of the engine cooling system. As a result, a higher charge pressure has been achieved much faster. This situation considerably shortens the time required to obtain maximum charge in the combustion chambers. This ensures that the engine has improved dynamics.

Thanks to the high torque offered at low revs, no matter which gear you are in, the turbo and direct fuel system used in your request for instant acceleration will respond to your engine demand in a very short time. Thanks to these technologies used in the TSI engine, very high power values ​​have been obtained from very low volume engines. A small volume engine means less friction and a lighter engine. In this way, performance losses due to friction are prevented and the total weight of your vehicle is reduced with low weight. This has a positive effect on performance and fuel efficiency.
