TDI: Start a revolution.
And keep repeating it.
Technology | TDI
The piezo injectors open and close in
fractions of a millisecond and inject
fuel several times into the combustion
chamber at pressures of up to
1,800 bar. In some cases, an injection
process can involve the injection
of the tiniest of amounts weighing
less than a thousandth of a gram.
Pre-injection results in a “gentle”
combustion process and consequently
excellent combustion acoustics
and agreeable engine running
characteristics.
One in every two Audi cars sold today is a diesel.
What sounds perfectly normal now was cause for
huge excitement 20 years ago, when Audi
revolutionised the market with the first 2.5 litre
TDI engine. Since then, developments such as
common rail technology have made TDI even
more efficient. Piezo injectors ensure the fuel is
finely and precisely distributed. Consequently,
since the first TDI, the engines have become
around 30% more economical, whilst specific
output has increased. So it was only logical that
a diesel car should then enter the world of
motorsport. With great success: in 2006, the
Audi R10 TDI became the world’s first diesel
powered race car to win the Le Mans 24 Hours –
a victory which it has repeated several times over.
A 2.0L powerful TDI Engine available on Audi A6,
operates with intelligent common rail diesel
technology. It generates 130 kW power and a
healthy torque of 380 Nm @ 1750-2500 rpm.
