What is TDI?
TDI Full form is Turbocharge direct ignition, The well-known Volkswagen Group in Europe is responsible for developing this technology. All of the mainstream Volkswagen Group passenger car and light commercial vehicle brands employ these TDI (turbocharged direct injection) engines. Volkswagen Marine and Volkswagen Industrial Motor both utilize these engines for marine purposes.
WORKING OF TDI :-
There is direct injection in a TDI engine. It’s a technique wherein fuel is sprayed into the center of the combustion chamber under high pressure. The turbocharger boosts the air pressure going into the engine’s cylinders. In addition, the engine temperature can be lowered using an inter-cooler, allowing more gasoline to be injected and burned. This means a TDI engine can provide more torque while using less fuel. The smaller surface area of the TDI increases efficiency and decreases combustion noise when running.
TDI Engine ADVANATGE:-
- TDI engine are running quite.
- They are more efficient
- TDI engine are more clean
- TDI engine will give more Torque and Power.
TDI Engine DISADVANTAGE :-
- Maintenance of TDI is quite high.
- TDI engine emit NOx emission.
- TDI engine are quite expensive than petrol engine.
- The cost of spare parts is also high.
Which cars have a TDI engine?
Volkswagen has labeled a number of their vehicles with the TDI designation. This includes Audi, Seat, and Skoda, all of which are part of the Volkswagen Group.
Once upon a time, TDI engines were available for smaller hatchbacks like the Volkswagen Polo, Seat Ibiza, and Skoda Fabia, but now they aren’t.
The Volkswagen Golf, Seat Leon, Skoda Octavia, and Audi A3 are now each manufacturer’s entry-level diesel offerings.
Larger sedans like the Volkswagen Arteon, Skoda Superb, and Audi A6, A7, and A8 all feature them.
Audi’s performance-oriented S models use TDI engines, too, including the S4 and S5.
The Volkswagen Group provides at least one SUV option with a diesel engine. With a few notable exceptions, such as the Volkswagen T-Cross, Seat Arona, and Skoda Kamiq.
What types of TDI engines are available?
The 2.0-liter TDI engine is the workhorse of the current VW Group TDI lineup. Countless vehicles, from the Volkswagen Golf to the Audi Q5, and everything in between, feature this engine.
The 3.0-liter TDI is available on several of the higher-end versions. Some SUVs, such the Volkswagen Touareg and the Audi Q7, and the Audi diesel S models fall into this category.
What’s the difference between a TDI and a TSI engine?
The VW Group’s diesel engines are designated by the TDI engine designation, while their turbocharged gasoline engines are designated by the TSI designation.
TDI engines, like most diesel engines compared to petrol engines, will typically have higher fuel economy than a TSI (especially if you do a lot of long freeway drives). However, TDIs are more expensive to buy and often have higher fuel expenses per liter than other vehicles.
Similarly, Volkswagen, Seat, and Skoda all use TSI in many of their vehicles.
