The times are long past, where diesel engines were slow acting, woke
up the whole neighbourhood during morning start-up, and black
smoke was trailing out of the exhaust when driving at full speed.
The driving performance, dynamics as well as vehicle comfort,
economy and emissions have been significantly improved through
further development of all engine components, combustion
procedure, materials and machining procedure as well as the injection
pressures.
In order to comply with strict exhaust gas emission regulations and to
lower the fuel consumption at a high performance,
Škoda
Auto a. s.
relies on the TDI Engine generation with 4-valve technology.

Introduction
2.0 ltr./103 kW or 100 kW
*
TDI Unit Injector Engine with 4-valve technology
SP57_01
The 2.0 ltr./103 kW or 100 kW
*
TDI Engine is
the first representative of the new generation
of TDI Engines with 4-valve technology from
VOLKSWAGEN. A 100 kW version of the
engine has already been fitted in the
Volkswagen Touran. It has been developed
from the 1.9 ltr./96 kW TDI Engine.
The enlargement of the displacement in
comparison to the basic engine was achieved
by increasing the size of the cylinder bore.
The new 2.0 ltr/103 kW or 100 kW
*
TDI Engine
has a newly developed crossflow aluminium
cylinder head with two inlet and two exhaust
valves per cylinder.
Other technical highlights are:
• switchable radiator for exhaust gas
recirculation,
• crankshaft sealing flange with integrated
sensor rotor for engine speed,
• new glow plug system.
*
The 2.0 ltr./100 kW TDI Engine is only
intended for the Belgium market.
