VOLKSWAGEN TDI TECHNOLOGY EXPLAINED !!

Turbocharged direct injection engine is invented by Volkswagen group. TDI identifies all advanced diesel engines using direct fuel injection and a turbocharger. TDI engines are economical and smooth with high levels of torque and good energy efficiency.

Working of TDI

Fuel needs oxygen to burn and the engine has to be supplied with huge quantities of air to get enough. You can solve this problem with a bigger engine - or you can solve it with a turbocharger - as in the TDI. Driven by the exhaust gases, it squeezes air more tightly into the cylinders.

After being drawn through the turbocharger the air is then cooled by passing it through an intercooler, before entering the combustion chamber where diesel is injected directly into the cylinders at very high pressure through a nozzle. It's this intensive mixing of highly atomized fuel with the cooled compressed air that leads to better, more efficient combustion.

Your driving experience is quiet and refined because effective sound keeps noise to a minimum, while hydraulic engine ensure smooth, low-vibration running.
