What does jetta tdi mean

Here diesel is injected directly into the cylinders through a nozzle at an extremely high pressure, which breaks it down to a very fine mist. So, what does this mean for drivers? Read More: vs Golf. When you have a hard time remembering which one is which, think of the D in TDI meaning that it has the diesel engine.

The Golf TDI on the other hand, offers more torque. Diesel might be going through a tricky period right now, but it remains the fuel of choice for many larger cars and for anyone who needs to cover long distances. Diesel cars consistently offer better fuel consumption than an equivalent petrol car and offer comparable refinement too. The boom in diesel during the s and s is in no small part due to the many refinements and advances in diesel technology that took place during this period, and the TDI engine was a significant part of this.

This means more air is packed into the combustion chambers and so more fuel can be mixed with it, delivering more power for a given amount of fuel. Non-turbocharged diesel engines were typically economical but low on power; since first arriving in the late s, turbocharged diesels gave a much-needed power boost while still retaining the all-important fuel economy.

Other technologies such as CRT particulate filters and catalytic converters burn soot and reduce particulate matter, carbon monoxide and hydrocarbons by as much as 90 percent. 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. The fuel has to mix swiftly with the compressed air in the cylinder.
