1.4 tsi how does it work

With its intricate engineering, the TSI family of engines is able to outperform bigger engines. Diesel engines are known to be more fuel efficient than traditional combustion engines without a hybrid-electric drivetrain.

So, by making a traditional combustion engine work more like a diesel engine, Volkswagen has been to push the fuel economy of their vehicles forward. Somewhat counter-intuitively, Volkswagen has made their TSI engines more complex while simultaneously making them more affordable to produce. That means lower prices for consumers. Schedule a test drive in a Volkswagen of your choice and see what the TSI engine can do for you. You can follow any responses to this entry through the RSS 2.

More from Hall VW. This makes cars equipped with these engines more lively at lower revs, which in turn makes them more economical and cleaner. When comparing an older 1. Saving money without forfeiting performance sound too good to be true, which is why we need to examine Turbo Stratified Injection further.

The first driving principle behind the system is direct fuel injection. This ensures less pumping losses and a more efficient combustion, thus increasing fuel economy. The TSI engine combines direct injection with turbocharging and in some cases even twincharging, as the some performance-oriented 1.

Another important component for a successful TSI is an intercooler to reduce the temperature of the air coming into the engine and thus allow more of it to come in and reduce the posibility of detonation, or engine knocking. An easily overlooked element of TSI technology has always been downsizing: 3-cylinder engines replacing 4-cylinder one, 1. Volkswagen never stops inventing new technology to make their TSI engines competitive. The older 1. Here are some of the most important and widespread TSI systems: 1.

It shows Volkswagen wants its customers to have a downsized alternative, just like the 1L engines offed by Opel and Ford. The first major application of this 3-cylinder TSI was come with the Polo facelift. However, soon after its launch Audi also introduced the A1 ultra with the same setup, followed by the Skoda Fabia.
